hello, buddy, if you want have a electric bicycle! you could have a look of my BLOG and site, here have foldable, mountain, ebike! please search "lilyebike" by google
Well expectedly I'm not a big fan of them. But now that I've had some time to think Electric bikes are really not that bad. A 10mile ride can be done by bike, but if I have to commute for 20 miles or more than I'd rather forgo my pride and arrive to work unflustered and not sweaty.
On an electric bicycle you are saving the environment but cheating yourself of the greatest joy of cycling, that is the physical movement that it demands.
Fine it will save the environment but you are cheating. You're using the lazy option and I hate lazy people.
Sorry if I seem to hammer on, but, the fact is for the money you pay for a decent electric bike, you'll get into a decent road or hybrid bike. (totally pedal powered) The road bike will weigh half as much, lasts 20 years and is as easy to pedal quickly as the electric. I recently rode a $2000 electric bike, and because of the battery weight, even with electric assist could barely make 24km/h. On my road bike I average 30km/h. Battery weight kills electric bike performance, battery life sucks.
Your entirely correct, and you should be congratulated for having the fittness for using a normal bike. BUT, you have also missed the point.
About 95% of people dont want to rise a bike, because they dont want to raise a sweat, change their clothes or dread the trip home. An ebike solves that! I have nothing against bikes, in fact I have one and use it often.I also know there are many people who will not use an ordinary bike often. Many of those same people are willing to get on an ebike.
And that's the point of an ordinary bike, you don't have to raise a sweat - 5 times more energy efficient than walking the same distance. I don't raise a sweat, I dress appropriately for work and I travel quickly. No batteries, no badly designed compact frame bike, just a fast, easy, comfortable road bike. You simply ride and you get better at it every day. Why fuel a vehicle when you can fuel yourself with gourmet food?
your still missing the point. I am a martial arts instructor. (obviously fit as f&ck). I use an E-bike.
Why travel 18 miles to work by subway and bus when I can bike it? I doubt I'd make it 18 miles of hilly roads on an ordinary bike and then be able to teach 8 hours of TKD. Well an ordinary bike wont cut that situation...and I get some light exercise. I CAN make it on an ordinary bike BUT I wont be able to do my job!!!
PS e-bikes are 4 times more energy efficient than normal bikes, Kj per Kj.
Look at all the views some of these electric bike video clips are getting? How many of them go over a bona fide 27 miles per hour and can go for over 10 miles per charge without pedaling a stroke? The Electric Horse™ does and I have a patent pending on an even better looking and functioning mod' that will be approved some time in June. Ashamed to see people wasting $ on ? bikes instead of buying the answer bike: Electric Horse™ Wiscokiddd on you tube.
I myself am looking to put a 72 volt etec electric motor on my bicycle. not recharging itself yet hough, but soon hopefully, i am trying to use lithiom batteries, but if i have to, lead acid i will have to try.
This is a follow up to my previous comment. Why should you need batteries at all if the generator and motor has an effiency of over 100%? Then you could just connect the generator directly to the motor, give it one kick to get it started, and it would run forever. I think you should start read some basic physics before posting more comments.
well, u can run 10 to 20 alternators up at a time on a belt running at a nice rpm since electric motors rev up past 3,000 rmp. gotta think outside of the box, or just rip the box up and use you're emagination. humans whent on the moon,. u can make a bike that charges itself.
I can't believe you are 22 years old. You really think you have the solution for perpetual motion? I thought so too, but at that time I was 5 years old. Unless you dropped out of elementary school, you should know that energy cannot be created. Only converted from one form to another. This is not about thinking out of the box. This is about thinking at all. Going to the moon has always been physically possible, but this is not. Why don't you make a time machine when you're started?
Interesting, but...what's the city? Bikeparadise? For me is not possible riding so safely trough the city to go job, and also the distance is too great (more than 25+25Km). If the distance is greater than 8-10Km, the real alternative to the car is subway, if there is.

i see, i see, u guys would rather just say, it'll never work. because it's hard to try to make something work. but when someone does it, u'll say, i knew it would work. lol. try it out or put 3 or 4 alternators. Life is not about saying it's too har, it's about doing it because it is hard.
So you think you have the solution for perpetual motion? You think you have invented somethink scientist never thought of? I was thinking just the same when I was 5. I connected a motor to a generator, but was very dissapointed. The problem with the idea is that energy cannot be created, only converted from one form to another. In other words, the effiency of a motor or generator cannot exceed 100%, but most people know that. Why don't you make a time machine when you're started?
Look very closely at high efficiency electric magnet motors perhaps even with magnetic floating bearings.
Then look at the magnetic alternators used for wind generators.
None of these are fully permanent magnet driven just assist but the trend is that each are becoming more efficient, if you are a visionary you can see where this is headed.
wind generators spin with less resistance & produce higher output at lower RPMS. problem is overheating at the lower RPMS
riding bikes every where is so much better. for time and the world. i mean no gas emissions. but it's not always safe, you cant always know where to ride. and it makes you sweaty ];
why wouldn't u put an alternator on your bike so u can drive and charge your battery at the same time?? never recharge at home again, drive forever on a single charge!!
Are you serious??????? Is this a real question?? An alternator is only 40 to 80% efficient so you would be losing 20 to 60% MORE ENERGY BY DOING THAT!!! So what you are saying is that you can connect an alternator to an electric motor, spin the shaft and it will go forever? Go back to 6th grade and learn the basics of science please before posting moronic statements like this.
It's not so moronic if you are thinking more along the line of regenerative breaking where the motor acts as a generator (alternator) going down hill.
Imagine if your parents or school teachers called you a moron every time you got something wrong, you can't be all that perfect in life, try educating without the sarcasm that makes your insignificant self feel better.
If you research electric motors they continue to be more & more efficient, floating magnetic bearings etc.
Then explore alternators used for wind generators that can spin with less friction (easier) and produce higher output at lower RPMS. What happens? The impossible? I don't give a rats ass what science says, Science becomes outdated, how many times has the impossible become possible, science fiction become science fact, science always lags behind due to politics and corporate control
Electric motors are of course getting better and better, with effiencies very close to 100%, but this was also predicted from the day the first electric motor was made. Today we are just more certain than ever that perpetual motion is completely impossible, because we know more than we did at that time. Most people don't believe in science because they have no idea what scientist are taliking about, and because perpetual motion sounds so fantastic, compared to the "boring" truth.
I also agree science becomes outdated. The theory of relativity and quantum physics are most probably getting replaced by a newer universal theory like string theory, but this is not because there is something wrong with the old science. We are just finding new ways to explain the old physics in an easier way, and find connections we didn't know existed. Also, basic physics like this is just proven to be more relaiable than ever, because we get new ways of testing the old laws.
I have not yet placed my hands on one of these claimed perpetual or Overunity devices but I believe there is something many objectors are failing to see. Some have a measurable input of electrical current.
properly aligned permanent magnets boost rotation then when output ability is measured it is higher then measured input current. Nobody is taking into account how much force is being used from the magnets, I don't think there is a device yet that measures permanent magnet output.
People love to discount this just to win an argument at all costs claiming magnets do not have a charge when in fact a demagnetized magnet can be remagnetized (recharged) Science took 70Yrs to prove a bee could fly and did so when the tools to prove it became available. It took science 5yrs after flight before "heavier than air flight" was recognized, Science always lags behind.
Magnets put to work will discharge in approx 100 yrs or so and I realize the term perpetual is an inaccurate term because it means never ending, everything ends eventually so the term overunity came about but according to my description above once the output of magnets can be measured there is no magic no overunity or perpetual, in time a set of magnets will cost $10,000 to make up for lost oil & coal industry
you should read wikipedia on perpetual motion and the "seemingly mysterious ability of magnets to influence motion at a distance without any apparent energy source has long appealed to inventors" because you are seriously lagging behind in science.
"device or system that delivers more energy than was put into it."
same goes with electrolysis to get hydrogen and oxygen from water as fuel. it still take more energy for electrolysis than the amount returned from extracted hydrogen and oxygen
Exactly! It is pretty funny that you mention the water-driven car. A couple of friends of mine is actually still believing they can make a completely water-driven car. Even funnier; they think they can put the waste matter, which of course is water, back into the cell and drive forever. When I say it isn't physically possible and explain why, they often answer "Einstein did mistakes as well, didn't he?". Haha, some people have too much confidence in their own work...
i've been throught many ideas and many others have already done them before.
it all seems so easy.
the laws of thermodynamics have done so much not by explaining what we cannot do but what we CAN do, HOW and WHY so i would not go as far as saying "the science is wrong".
you know how much shit that would undo if the laws were proven wrong?
For jmagish - a FORTNIGHT is two weeks - a week is seven days - a day is 24 hours - an hour is 60 mins and a minute is 60 seconds - a second is the time is takes to say 'fortnight'.
yeah i have an electic bike. gets me to work just as quick as the car, plus i also get to sit there and rev the tits off the thing to 23mph.. save me loads on what petrol would cost in me citroen saxo..
"the bike wont take you get groceries..." Wrong. When shopping for just me, I can fit a fortnight's groceries in 3 of my panniers with room to spare for goon bag of red and a 6-pack in the spare rear. When I'm shopping for when my kids come over, I use a backpack, too. I have a trailer with an extra-long drawbar which will haul up to a 3 seater couch. My bike has no motor, it doesn't need one, even when towing 200kg on the trailer. No, I'm not a hippy, either! (sheesh!)
"the bike wont take you get groceries...and...what good does a bike when you go to the home depot?? "
About as good as a motorcycle or moped. What the hell is your point?
The point of this video is to show that you can get to work FASTER with a 36v or higher electric bike than an ugly SUV, save a ton of cash on gas, insurance, repairs, parking, and maybe even loose that gut. ;-)
OK, cool, but think of this, where are the batteries going when they die? Battery technology is pretty ugly environmentally. A better solution would be a biofuelled, microdiesal engine built into the back wheel - like a Sachs system, but not a smelly, noisy two-stroke like the Sachs
Car batteries have a small amount of lead and sulphuric acid in them. Lead is easily recycled. Electric bikes and hybrid cars use either hydride or lithium battery technologies. These are NOT easily recycled, this is the same techno waste that makes old computers such a landfill hazard, too.
EV's never include electricity generation carbon emmissions. Say you use a 250 watt motor for 4 hours. To get that kwh at a bike's wheel, you have a 60% loss, a battery has a 70% loss, battery charger 50%, transmission lines 90% and the power station turns 90% of the energy available in the fuel into electricity. That's an energy transfer of 17% from the fuel that fired the power station. A 4 stroke engine will transfer about 20%. Just get a good road bike and train your legs up, sheesh.
You are forgetting about things such as recharging from a solar panel, wind generators, regenerative braking, etc. I quite often arrive at my destination with a fully charged battery using nothing more than regenerative braking. I live in a mountainous area.
And you are forgetting that if you just use the pedals, instead of trebling the weight of the bike (or more) with batteries and a motor, you can travel for 16km on the calories in a bowl of rice - 5 times the distance you can walk for the same energy. And as for solar panels, they have an enormous energy input cost in manufacturing. Electric bikes are a load of wank.
It's important to remember what is carried with some people to their jobs: Change of clothes, safety gear such as gloves, kevlar sleeves, maybe a hard hat, a big lunch because you need a big lunch when you aren't working in an office, possibly a toolbox... it's nice to have an electric bicycle to assist with all that. You'd not be able to pedal 50+ pounds of stuff to work with you and still be good for anything except sitting down for 8 hours.
It also takes quite a bit of energy to manufacture a bicycle whether it be steel, aluminum or carbon fiber. And while we're at it don't forget the rubber on the tires, brakes handlebars and on and on. Even producing the bowl of rice you mentioned has an impact on the environment. There is no such thing as a free ride. You make your choices and you pay the price...
However, that is taking it to silly extremes. Getting up in the morning generates carbon. The fact is, a plain bicycle is the most efficient machine ever invented, requiring only one fifth the energy required to walk similar distances. Electrifying bikes, overly complicates them, robbing the bike of its other advantage, it's the last great technological leap a non-engineer could understand and fix. And there is 4x the carbon released making an electric bike battery than the bike itself.
bandmassa, my calculations show that it costs 60 cents kwh from a typical 5KV petrol generator (if you could magically meet its continuous rated output) compared to 13 cents kwh from the lines. Obviously a single power station is more efficient than 1 million small generators. cont...
I wasn't talking about running an EV from a generator, I was talking about EVs V. petrol engined vehicles, and I wasn't talking about the running cost, I was talking about the hidden environmental costs that people ignore when talking about EVs. The fact is an electric bicycle is "guilding the lily" compared to the plain, common, pedalled bicycle. Electric bikes are for lazy buggers.
Without the electric motor I was to lazy to tackle the local hills here. With the electric motor I'm hardly using the car anymore. Most people peddle with the electric motor so it does help get people fitter to the point that they use the electric motor less and less. If electric motors get some of us lazy buggers out of our car seats then I'm all for it.
Fair enough, but in nearly 20 years of bicycle campaigning, I've found I can get people cycling just as easily by demonstrating that cycling is already lazy buggers' exercise (that's why I took it up ;-) and Hobart is a damned hilly city.
That's like saying cars are for people too lazy to walk 50 miles. The fact is that electric-assist bikes allow faster and farther travel at a very low cost. We are going electric, on four wheels and two wheels. If you still want to pedal - that's fine, but don't knock something just because you don't feel you need it, maybe others do.
As I say, I'm a lazy bugger and ride as much as 30km day (15 each way) over undulant terrain. It takes only 5 minutes longer than driving, parking and walking the same distance and I don't arrive sweaty because I stay just on the boundary of my aerobic zone. (If I can still sing in key on a hill climb, I'm going to fine when I get to work ;-) The issue with leccy bikes is not what they put out in use, but what it costs to make the battery - 4x the carbon it cost to make the bike.
bandmassa, also it costs much less than .1 of a cent per km to recharge batteries (Im using a kwh meter to measure the battery recharge) and another 1.0 cents per km for battery replacement (using A123 cells with min 2000 recharges).
1.1 cents km for electric bike
1.3 cents km for .31cc petrol bicycle motor
9.0 cents km for small fuel efficient car (not included maintenance and reg costs)
That 1.1 cents km for electric bike is based on a minumum claimed 2000 charges from A123 cells, hopefully in real life it will work out something like .5 of a cent per km, if I can get about 4000 re-charges from the A123 cells (dewalt 36v batteries).
You are not realizing that some people are using e-bikes to replace trips in their 3000 pound CAR. That makes the e-bike much more efficient. Gas engines waste 3 quarts of every gallon in heat and friction (and pollute). Electric motors are over 90% efficient. The reason you ride a bike rather than walk is because it is faster and more efficient - that's why people are going electric. You may want to pedal your ass off - others don't want to, and that's their choice, don't you think?
NiCad are terrible in this respect its true. But environmentally even the posinous cadium far outweigh the environmental adv.
no pollution...and 35% more energy effiecient than any other means of transport including cycling REGARDLEES OF THE ENERGY SOURCE according to reseach carried out at the Uni of Pennsilvania.
NiCads are not geenrally used for Ebikes because they are older tech. and are potentially env. harmful.
How many acres of farmland(+greenhouse gases) are required to generate the energy that you use to pedal the bike? Lucky if the system is 1% efficient. The eBike is far cleaner and more efficient. You should never pedal yourself.
Oh, where does the electricity to power the eBike come from? 80% of the world's electricity is coal fired. If I walk 3km to work for 20% energy burn above my sleeping metabolic rate, I can cycle 15km for the same energy burn. The energy the eBike needs to burn is not just my weight and the bike, it's got the motor, controller and battery weight, too. The battery uses 70% of the energy put in it and the mains electricity to charge accounts for about 60% of the energy in the burned coal.
Yes, but the ICE engine is only 18% (at best) efficient. Also the human body as a motor is only 30 to 40 % efficient. The electric motor is 80% efficient and can regenerate and when its off its off. Regardless of the energy source the electric bike is approx. 35% more energy effiecient than ANY other means of transport...including walking...crawling around drunk or running or jogging or even joining the "ministry of funny walks" AKA power walking. :))
We need to lose some weight anyhow (most of U.S.)... and it requires oil (a scarce resource) to make these eBike batteries last time I checked, so I vote HUMAN powered!
sealed lead acid battries last forever if cared for properly if they enter the high discharge state and are deep cycled they can be recovered also lead can be recycled also NiMH can be too as well as lipos which have a high weight to power ratio anyway...your thinking of mobile phone batteries which are LithION.
In actual fact the car took closer to 40 minutes, while the bike took about 6! I didn't feel like pestering the editor over these details, so I just let it slide. The point is - in this case, bikes are fast, cars are slow!
inspiring vid. I love my electric bike, pretty much the fastest way to get around in Brighton except for a motorbike. good to see people trying to get the word out. Imagine a world in witch the majority of journeys were done by bike!
Cool video I like the comparison, the car journey sucks in comparison you also get to ride through the nice park as well which is a bonus, my commute is not quite as long winded by car but I cut it in half roughly on my 30mph e-bike and it costs me pennies in fuel if you like.

regenerative braking re-captures its power from inertia/kinetic energy.
i say re-capture because a car uses energy to move or climb a hill.
but there is no way you are going to get the same amount or even more of the energy back.
that would be perpetual motion.

I don't give a rats ass what science says, Science becomes outdated, how many times has the impossible become possible, science fiction become science fact, science always lags behind due to politics and corporate control

Electric motors are of course getting better and better, with effiencies very close to 100%, but this was also predicted from the day the first electric motor was made. Today we are just more certain than ever that perpetual motion is completely impossible, because we know more than we did at that time. Most people don't believe in science because they have no idea what scientist are taliking about, and because perpetual motion sounds so fantastic, compared to the "boring" truth.

I also agree science becomes outdated. The theory of relativity and quantum physics are most probably getting replaced by a newer universal theory like string theory, but this is not because there is something wrong with the old science. We are just finding new ways to explain the old physics in an easier way, and find connections we didn't know existed. Also, basic physics like this is just proven to be more relaiable than ever, because we get new ways of testing the old laws.

I have not yet placed my hands on one of these claimed perpetual or Overunity devices but I believe there is something many objectors are failing to see. Some have a measurable input of electrical current.
properly aligned permanent magnets boost rotation then when output ability is measured it is higher then measured input current. Nobody is taking into account how much force is being used from the magnets, I don't think there is a device yet that measures permanent magnet output.

People love to discount this just to win an argument at all costs claiming magnets do not have a charge when in fact a demagnetized magnet can be remagnetized (recharged) Science took 70Yrs to prove a bee could fly and did so when the tools to prove it became available. It took science 5yrs after flight before "heavier than air flight" was recognized, Science always lags behind.

Magnets put to work will discharge in approx 100 yrs or so and I realize the term perpetual is an inaccurate term because it means never ending, everything ends eventually so the term overunity came about but according to my description above once the output of magnets can be measured there is no magic no overunity or perpetual, in time a set of magnets will cost $10,000 to make up for lost oil & coal industry
FreeGlobalEnergy 4 years ago
you should read wikipedia on perpetual motion and the "seemingly mysterious ability of magnets to influence motion at a distance without any apparent energy source has long appealed to inventors" because you are seriously lagging behind in science.
"device or system that delivers more energy than was put into it."
same goes with electrolysis to get hydrogen and oxygen from water as fuel. it still take more energy for electrolysis than the amount returned from extracted hydrogen and oxygen

Exactly! It is pretty funny that you mention the water-driven car. A couple of friends of mine is actually still believing they can make a completely water-driven car. Even funnier; they think they can put the waste matter, which of course is water, back into the cell and drive forever. When I say it isn't physically possible and explain why, they often answer "Einstein did mistakes as well, didn't he?". Haha, some people have too much confidence in their own work...
jonpetter88 3 years ago
that was a fast reply.
i've been throught many ideas and many others have already done them before.
it all seems so easy.
the laws of thermodynamics have done so much not by explaining what we cannot do but what we CAN do, HOW and WHY so i would not go as far as saying "the science is wrong".
you know how much shit that would undo if the laws were proven wrong?
probably collapse and destroy the whole universe
ZO6 3 years ago
wow, this guy doesn't seem to understand the concept of perpetual motion.
this line really points this out:
"I have not yet placed my hands on one of these claimed perpetual or Overunity devices"
maybe because, they don't exist?
he thinks magnets can be used as an energy source LOL.
all science has done is further prove why it is NOT possible.
ZO6 3 years ago
it is a dumb question. Assuming that the double question marks are done for emphasis and not just a typo.
But it would be really cool if there was some way to do regenerative braking but I imagine the electronics would be too heavy to be effective.

OK, cool, but think of this, where are the batteries going when they die? Battery technology is pretty ugly environmentally. A better solution would be a biofuelled, microdiesal engine built into the back wheel - like a Sachs system, but not a smelly, noisy two-stroke like the Sachs
bandmassa 4 years ago
And where do car batteries go when they die? Same place as bike batteries for the most part.
zeuserx 4 years ago
Car batteries have a small amount of lead and sulphuric acid in them. Lead is easily recycled. Electric bikes and hybrid cars use either hydride or lithium battery technologies. These are NOT easily recycled, this is the same techno waste that makes old computers such a landfill hazard, too.

OK, but including the pollution that a car makes, I believe that an EV causes less harm to our planet overall.
RockManAU 4 years ago 2
EV's never include electricity generation carbon emmissions. Say you use a 250 watt motor for 4 hours. To get that kwh at a bike's wheel, you have a 60% loss, a battery has a 70% loss, battery charger 50%, transmission lines 90% and the power station turns 90% of the energy available in the fuel into electricity. That's an energy transfer of 17% from the fuel that fired the power station. A 4 stroke engine will transfer about 20%. Just get a good road bike and train your legs up, sheesh.

You are forgetting about things such as recharging from a solar panel, wind generators, regenerative braking, etc. I quite often arrive at my destination with a fully charged battery using nothing more than regenerative braking. I live in a mountainous area.
02134B 4 years ago
And you are forgetting that if you just use the pedals, instead of trebling the weight of the bike (or more) with batteries and a motor, you can travel for 16km on the calories in a bowl of rice - 5 times the distance you can walk for the same energy. And as for solar panels, they have an enormous energy input cost in manufacturing. Electric bikes are a load of wank.
bandmassa 4 years ago
It's important to remember what is carried with some people to their jobs: Change of clothes, safety gear such as gloves, kevlar sleeves, maybe a hard hat, a big lunch because you need a big lunch when you aren't working in an office, possibly a toolbox... it's nice to have an electric bicycle to assist with all that. You'd not be able to pedal 50+ pounds of stuff to work with you and still be good for anything except sitting down for 8 hours.
Oddman1980 4 years ago 2
It also takes quite a bit of energy to manufacture a bicycle whether it be steel, aluminum or carbon fiber. And while we're at it don't forget the rubber on the tires, brakes handlebars and on and on. Even producing the bowl of rice you mentioned has an impact on the environment. There is no such thing as a free ride. You make your choices and you pay the price...
Wank indeed...
02134B 3 years ago
However, that is taking it to silly extremes. Getting up in the morning generates carbon. The fact is, a plain bicycle is the most efficient machine ever invented, requiring only one fifth the energy required to walk similar distances. Electrifying bikes, overly complicates them, robbing the bike of its other advantage, it's the last great technological leap a non-engineer could understand and fix. And there is 4x the carbon released making an electric bike battery than the bike itself.

I wasn't talking about running an EV from a generator, I was talking about EVs V. petrol engined vehicles, and I wasn't talking about the running cost, I was talking about the hidden environmental costs that people ignore when talking about EVs. The fact is an electric bicycle is "guilding the lily" compared to the plain, common, pedalled bicycle. Electric bikes are for lazy buggers.
bandmassa 4 years ago
Without the electric motor I was to lazy to tackle the local hills here. With the electric motor I'm hardly using the car anymore. Most people peddle with the electric motor so it does help get people fitter to the point that they use the electric motor less and less. If electric motors get some of us lazy buggers out of our car seats then I'm all for it.
IQchallenged 4 years ago
Fair enough, but in nearly 20 years of bicycle campaigning, I've found I can get people cycling just as easily by demonstrating that cycling is already lazy buggers' exercise (that's why I took it up ;-) and Hobart is a damned hilly city.
bandmassa 4 years ago
That's like saying cars are for people too lazy to walk 50 miles. The fact is that electric-assist bikes allow faster and farther travel at a very low cost. We are going electric, on four wheels and two wheels. If you still want to pedal - that's fine, but don't knock something just because you don't feel you need it, maybe others do.
OregonDARRYL 4 years ago
As I say, I'm a lazy bugger and ride as much as 30km day (15 each way) over undulant terrain. It takes only 5 minutes longer than driving, parking and walking the same distance and I don't arrive sweaty because I stay just on the boundary of my aerobic zone. (If I can still sing in key on a hill climb, I'm going to fine when I get to work ;-) The issue with leccy bikes is not what they put out in use, but what it costs to make the battery - 4x the carbon it cost to make the bike.
bandmassa 3 years ago
bandmassa, also it costs much less than .1 of a cent per km to recharge batteries (Im using a kwh meter to measure the battery recharge) and another 1.0 cents per km for battery replacement (using A123 cells with min 2000 recharges).
1.1 cents km for electric bike
1.3 cents km for .31cc petrol bicycle motor
9.0 cents km for small fuel efficient car (not included maintenance and reg costs)
IQchallenged 4 years ago
That 1.1 cents km for electric bike is based on a minumum claimed 2000 charges from A123 cells, hopefully in real life it will work out something like .5 of a cent per km, if I can get about 4000 re-charges from the A123 cells (dewalt 36v batteries).
IQchallenged 4 years ago
How do you hook up the a123 cells for a 36v electric bike motor designed for 3 sla 12 v batteries? thanks
value505c 4 years ago
You are not realizing that some people are using e-bikes to replace trips in their 3000 pound CAR. That makes the e-bike much more efficient. Gas engines waste 3 quarts of every gallon in heat and friction (and pollute). Electric motors are over 90% efficient. The reason you ride a bike rather than walk is because it is faster and more efficient - that's why people are going electric. You may want to pedal your ass off - others don't want to, and that's their choice, don't you think?

NiCad are terrible in this respect its true. But environmentally even the posinous cadium far outweigh the environmental adv.
no pollution...and 35% more energy effiecient than any other means of transport including cycling REGARDLEES OF THE ENERGY SOURCE according to reseach carried out at the Uni of Pennsilvania.
NiCads are not geenrally used for Ebikes because they are older tech. and are potentially env. harmful.
ogicabp4u 3 years ago
How many acres of farmland(+greenhouse gases) are required to generate the energy that you use to pedal the bike? Lucky if the system is 1% efficient. The eBike is far cleaner and more efficient. You should never pedal yourself.
takarada 3 years ago
Oh, where does the electricity to power the eBike come from? 80% of the world's electricity is coal fired. If I walk 3km to work for 20% energy burn above my sleeping metabolic rate, I can cycle 15km for the same energy burn. The energy the eBike needs to burn is not just my weight and the bike, it's got the motor, controller and battery weight, too. The battery uses 70% of the energy put in it and the mains electricity to charge accounts for about 60% of the energy in the burned coal.
bandmassa 3 years ago
Yes, but the ICE engine is only 18% (at best) efficient. Also the human body as a motor is only 30 to 40 % efficient. The electric motor is 80% efficient and can regenerate and when its off its off. Regardless of the energy source the electric bike is approx. 35% more energy effiecient than ANY other means of transport...including walking...crawling around drunk or running or jogging or even joining the "ministry of funny walks" AKA power walking. :))

Hi
Cool video I like the comparison, the car journey sucks in comparison you also get to ride through the nice park as well which is a bonus, my commute is not quite as long winded by car but I cut it in half roughly on my 30mph e-bike and it costs me pennies in fuel if you like.
