Have you experimented with supercapacitors? They can dump HUNDREDS of amps without overheating, they can charge really fast and can withstand over a million charge cycles. Oh, and they're cheap too.
@rstevewarmorycom A hybrid design involving both batteries and supercaps can allow for both strong accelerations and good range. When cruising at a constant speed, not much energy is required, providing time for the supercaps to charge up. This design would be a little more complex, but I'm sure it's worth it.
@rstevewarmorycom I never said this was a new idea, I was just asking the poster of the video if he had experimented with this kind of set up.
I don't like the idea of regenerative braking; a brake is supposed to stop you bicycle, not recover energy. Regenerative brakes add a substantial amount of weight to the bicycle, decreasing efficiency overall. Plus, what happens when your "brakes" fail? You can put yourself in a very dangerous situation. Regular brake pads are the way to go.
Incredible bike! Can someone please give me some tips about bikes? I'm wanting to get either an electric or motor bike to get around faster but don't know which to get. Electric bikes I hear don't go very fast but save $ over time and motor bikes are hard to build and require a lot of upkeep yet can fly down the street like the one in the video. I'm not rolling in $ but I've saved up some for a good one. I don't know which to get, can someone give me advice? Thanks!
Why not try (Less revolution)Front Drive motor with Bigger Wheel 26" n the "2nd Rear Charging motor with bigger Watt n Current but smaller whel 24" (turning faster) to charge back electricity into the Battery, both Motor positive wire with single powerful DC Blocking Diode in series, so U won't need to go home and Charge it regulary. The Travell DISTANCE might get more.....
@biodiversivist "perpetual motion machine "with 2hub motor on 1 Battery, Front wheel is a Drver motor as usual but the Back rear smaller hub motor (do nothing) just charging back the battery when its operate. The Battery should ve "2 postive wire" in Diode series with the rear and the want coming out from the battery to the front wheel with blocking Diode aswell. Becoz the wheel size's difference, the back wheel should be more revolution for it to generate the electricity back into the Battery
@biodiversivist Not really. You Could conceivably add a generator capability to the front wheel. That would send a trickle charge back while moving, and a larger amount back while coasting downhill. You will never get back what the battery packs put out. But you can increase the range by decreasing the load on the batteries. Electric cars use the same technology to increase range.
@Drdump1 sure that would work but then the charging wheel would create drag and you wouldn't gain anything from the electric motor.....you might as well just have a pedal bike.
@flyfkly The Electric Bicycle design now is changing into "Real Free Energy" type, people now is doing Solar Panel charges it back into their SuperCapacitor, When we talking about "Free Energy", any Battery use is just as a Energy Storage, no matter Up hill or Down Hill, here the ideal is use 1 of this Magnetic Wheel as a Generator to charges the energy back into the Ion-Battery or SuperCapacitor...so that your Flykly in future can travell around the world without looking for external electric s
i really like the idea of using relaible brand name batteries and chargers instead of importing them from sketchy sellers in china. if i build such a bike i think ill take your lead and use 2-4 of these puppies

ILL never go back to electric bikes again after building my mortorized bike.Takes three seconds to fill up instead of three hours of charging my super over priced batterys which were Lifepo batterys and the bike weighed a ton.

Yes, Busettii Bikes have the good pedaling system so you can use it as a bike or pedal with the motor. I have one and it runs about 75--85 miles per charge but you can also pedal like a regular bike. Also, it really goes fast even in throttle mode. Check out busettii dot com if you need more info. ciao

@biodiversivist I'm new to e-bikes and have noticed so and so watts and so and so volts and amps are always mentioned could you please explain what the watts, volts and amps mean in turns of requirements of needs ie lots of watts for speed or lots of? for torque, range etc please I'm clueless to all of this but once someone is kind enough to explain it I will get cracking on building a over the top one :-)
In a nutshell, stick to 36 or 48 volt systems. 72 volt systems like mine are rare and can be dangerous. Watts=volts x amps. A 750 watt bike is adequate. use some algebra to figure out the rest. ; )
Very nice looking work, I'd like an electric bike, not as much as my BMW but it'd be neat for running errands. How is it in the lower gears, will it do off road very well with pedal help? I've been daydreaming about an electric off road motorcycle for too long now, all that instant torque appeals to me.
Well worth the price. I rarely drain the batteries down but when I do, it is typically around 20-25 miles depending. Weight is around 80 pounds. They charge so fast you don't need much range and who wants to sit on a bike for more than 20 miles?
Because I rarely ride it to full battery amp-hour capacity, I don't really have an average distance. I tend to ride it about 12 miles between charges. I can stretch the range up toward 20 plus miles by pedaling a lot and going slower. It weighs about 80 pounds. Well worth the price.
Are you using them for power tools or for an electric bike? I've been using these batteries on my bike since late 2006. I have had to bypass the internal fuse on some and have replaced the BMS card on a couple as well after shorting them out during ah, experiments.
I was using one in a tool a few weeks ago and drained it. The charger refused to charge it so I let it sit for a couple of days and kept trying it in the charger until it accepted it again. One of the cells is getting weak.
have you figured out that those dewalt batteries are crap yet? Maybe not so much the batteries as the charger that dewalt supplies with them. Both me and a co-worker have had a half dozen of them crap out from multiple dewalt chargers. I have one good battery left. I get much better life out of my 28v milwaulkee batteries.
@anymanusa, they not broke so don't chuck them. Cells inside the batteries sometimes go outside the acceptable limits of the charger so it gives up the ghost. I have soldered two wires to positive and negative (36+-) inside each dewalt battery. If a battery doesn't charge properly I just connect the wires to a fully charges battery for couple minutes (positive to positive, negative to negative) then the dewalt charger will do its job. Might not be smartest way but seems do the job for me.
Dude, nice video. Great speech and camera work. Btw nice bike, my dad and I are into gas engines more but my grandpa is really into electric engines and i'd like for him to teach me more about them.
I like the alt fuel movement. My bike will have the batteries - but no motor. Instead, it will have a telescoping pole in the front, with an electromagnet on the end, powered by the batteries. Peddle out in traffic, latch on to a car, hit the kill switch when they turn off your route. Arrive at work looking refreshed! (haha)
How many amp hours are the batteries and you said in one of your post series and parallel. I have 2 tidalforce wavecrest I want to use these on as a b battery pack. They are a 40 amp hour battery motors at 36 volts. I have a cycle analyst and I thought I could limit the MPH and change the controller. What to you think?
You probably have to stick to the controller designed for use with those motors. If it is designed for 36 volts, you are stuck with it. It does not matter what battery you use as long as it is 36 volts. The motors could probably handle 72 volts but you are limited by the controller's max design voltage.
nice job!...hope you have better luck with those dewalt batts than i do with my dewalt nicad 18 volt. not all but some of mine get hot and im lucky to get a year out of them
The Dewalt 36V batterypacks use 10 A123 technology Lithium-ferro-nanofosphate 2300mAh cells in series. Wired for 72V-35A of continues use, we're talking 3.4HP, that's moped power, on a machine that weights less than a fifth. I guess we're going 40mph+. If the gearratio and motorcombination allows it.
But that kind of speeds eat batterypower, so, that explains the short range on 4600-6900mAh. Get the gearratio right for 25mph, and get an hour of freedom.
Fist off, why do people feel the need to leave pointless negitive comments, The bike looks great. I did the same thing to a Trek. However, after sittingover the winter. the sla's are bad. I am running at 48v (at least the controller is" Can you give me ideas on batteries, how much they might cost etc. I would really appreciate it,.
SLA batteries are cheap for a reason. I don' t advise using Dewalts unless you are very comfortable trouble shooting electric circuits. They are also not cheap, $180 each x 4 plus tax plus chargers.
True, but the bike cost less than one of my four battery packs. I've since replaced the brakes and crankset with very high quality ones because the originals have already failed ; )
I have a bike with 500 watt motor (36Volt). Can I use 4x 36 Volt dewalt battery pack ? Please tell me that how install 36 volt Dewalt battery pack in series? I had 3x12V battery 12Ah. This battery is really heavy like 25 lbs.
You can but I would advise you not to use them if you have to ask how to install them. They have an internal fuse that can blow and you would have to repair them yourself, Dewalt does not repair them or even sell parts for them. You can buy other lithium batteries for ebikes off the internet.
@dakotabu I rarely exceed 20 mph but can kick it up close to 30 in a pinch for a short time to avoid cars while on the road. The only thing special about this bike are the batteries. They can deliver a lot of power, don't weigh much, charge in less than an hour and have been going strong for four years now.
@biodiversivist You said in an earlier post you can get approx 25 miles range.These batteries seem a little low on amp hrs to get that kind of range.Are you wiring them in series as well as parallel for greater range?Any info on range/wiring would be very useful.I love the idea of these batts,but the tiny amp hrs kinda put me off.I will be running a Unite 350w 24v geared motor which will in turn be using the bikes deraillieur gears,so should have loads of torque.Thanks.
I always pedal to extend range. It's a bike, not a scooter. I have no problem doing a high speed 25 mile trip with hills. Range is a function of pedal power, battery capacity, motor efficiency, and speed. My bike, with me riding it the way I always do (fast) has a 25 mile range, no problem.
Two batts are in series and then they are in parallel with two more batts which are in series. Also keep in mind that they charge in less than one hour. I can use them all day.
@biodiversivist Also keep in mind that "they" charge in less than one hour. You have to bring six wall chargers with you on the road to charge your six batteries in less than an hour right?
I use four batteries so I only need four chargers. They all fit in my pannier bags. I rarely take them with me. except on really long rides. There is no free lunch.
Can you send me some explicit instructions on how to wire this up for my bike. I just ordered a wilderness 600watt brushless hub motor with controller (I am told it has a 50 amp controller) and have been told it has no problem taking 72 volts. I am going to mount it on a beach cruiser. Since it is my only transport and I need extended range and a quck charge, this seems to be ideal for me. I would appreciate any information you could provide to me as I am quite unskilled in electric. TY!!!
I don't recommend using these batteries if you are not skilled in electric circuits because things can go wrong and there are no repair shops. My advice, get a good quality 48 volt lithium ion battery from a reputable dealer on the internet. These are for hot rodders willing to do some soldering and fix things when they go poof ; )
A clear precise presentation. Good power packs. As an older dude, " and heavier now " i need a full frame with tricycle support of batteries, and basket cage. My trips would be 2 miles return, with groceries and library books. " i sure need this, " even if it comes to 3, or 4 thousand dollars, non rainy days, i would do all my travel this way, saving on sky train and bus fees, " pays for itself" in my budget, " if you build one, i will buy it " cheers Thomas in Vancouver Ca.
Wind resistance goes up exponentially with speed. It becomes a limiting factor at higher speeds as does pedal rpm. In the video you can see that the extra power comes in handy on hills where you can still do 20 mph, which is about how fast I'm going in the video.
Not a motorcycle. Speed kills, especially on a bicycle. Never checked its max speed. I typically cruise around 20 mph, push it to about 30 on rare occasions to keep up with traffic in a pinch.
Peddle, paddle, petal. Generators are hard to turn, especially when they are charging a battery. The idea is to use the charge in the battery to make your ride easier, not to make your ride harder to charge the battery.
You are probably wondering about capturing a tiny amount of energy using regenerative braking. Although the controller is capable of doing that, it isn't worth the added complexity on a bike.
Tiny amount? My understanding with cars is that it is quite a significant amount of regenerative energy re-captured from the braking.
Why would it be worth it on a car, but not a bike?
Are you saying the the extra weight of the mechanism itself adds more weight that the batteries have to push around when moving forward, so it is not worth it?
You need special brake levers with switches, which can be a source of maintenance problems plus the battery charging system for lithium battery packs can be complex, monitoring heat, voltage and current flow for each cell. You could damage it with a high current flow from your motor. Let's say you capture 10% of your braking energy, which I doubt. On a bike with a 25 mile range, you now can go 27.5 miles. Is it worth it?
Before I can answer I would rather have an actual figure than speculation. But it isnt just about the extra range, it's the fact that energy was used to create dthe forward momentum, and when you simply scrub that energy off with brake pads, it is wasted energy.
My understanding from automobiles is that the recaptured energy is closer to 25%. Now perhaps with that much extra inertia there is more to recapture, but I can't see why it would not hold true cont..
...on a smaller scale, unless the technology to do it on a smaller scale doesn't exist, or can not be implemented on a wheel that is the size and shape of a bicycle tire/brake caliper combination.
Everyone talks about how big of a deal and important braking is on these bikes to eliminate speed, it would be great to have a solid system that can turn that problem into an asset.
An electric motor? This is a brushless motor. It contains super magnets. The controller sends pulses with a frequency determined by the throttle position via the halls sensors. Not sure what your point is.
If you are riding a bike for exercise you can just lay off the throttle. With an electric bike you still get exercise, you just have more control over how much you get and what you smell like when you get to work. ; )
I've made my own custom design of a Hybrid Mountain Bike. But im keeping it a Secret on the Design also how i did it, I can say it does have a Electric motor But it also has something else added to it. Hmm.. I call it a 3 in 1 Motor Powered Bike.
What you've done is terrific! I've got an old Trek touring bike that I'd like to set up with something like this--do you have specific instructions on how to replicate your design?
It was cheap. Just today I put a $200 crank set on it because the bearings on the original fell apart, which cost more than what I payed for the whole bike.
The only thing left of the original shit bike at this point is the frame. For example, the crank now has a huge front ring (54 teeth) like you find on road bikes instead of the small ones on mountain bikes. I did that so I could continue to contribute to the power train at higher speeds, especially downhill. The tires are puncture resistant and low friction, it has fenders, and on and on. The frame seem to be adequate for street riding.
Sure. Most high-end controllers have regeneration capacity. Mine does but I did not bother to hook it up because regeneration returns a very tiny amount of energy, not worth the added complexity on a bicycle although it is worth doing on a Prius.
An excellent piece of engineering, has answered a few querys I had for my project, I also intend powering a leisure from solar panels and a wind turbine to charge the bike so I can use it for work, regards Nigel aka Doc Cox
Yes but all of the components I used have been redesigned by the manufacturer. The motor has relocated the spoke flange and the controller is much lighter. I used a controller rated to 100 volts and 45 amps.
I like your design: It does what it should do; it's out of the way, so you concentrate on riding, and you sound pretty happy with it. Cheers!

@yellowmetalcyborg Regen braking is not done as the
only method of braking, it is used more like engine braking
before regular pad brakes are applied at the very last.
rstevewarmorycom 1 week ago
@yellowmetalcyborg The pedal acts as a sensor and applies full regen and
to that adds as much regular brake as is needed according
to whether you push the pedal harder to stop more urgently.
All the regen is controlled by is the brake pedal switch, the
pedal still directly drives pad brakes. It's like power brakes
except the additional power brake stores it.

I was using one in a tool a few weeks ago and drained it. The charger refused to charge it so I let it sit for a couple of days and kept trying it in the charger until it accepted it again. One of the cells is getting weak.
biodiversivist 1 year ago
have you figured out that those dewalt batteries are crap yet? Maybe not so much the batteries as the charger that dewalt supplies with them. Both me and a co-worker have had a half dozen of them crap out from multiple dewalt chargers. I have one good battery left. I get much better life out of my 28v milwaulkee batteries.
anymanusa 1 year ago
@anymanusa, they not broke so don't chuck them. Cells inside the batteries sometimes go outside the acceptable limits of the charger so it gives up the ghost. I have soldered two wires to positive and negative (36+-) inside each dewalt battery. If a battery doesn't charge properly I just connect the wires to a fully charges battery for couple minutes (positive to positive, negative to negative) then the dewalt charger will do its job. Might not be smartest way but seems do the job for me.

I like the alt fuel movement. My bike will have the batteries - but no motor. Instead, it will have a telescoping pole in the front, with an electromagnet on the end, powered by the batteries. Peddle out in traffic, latch on to a car, hit the kill switch when they turn off your route. Arrive at work looking refreshed! (haha)

How many amp hours are the batteries and you said in one of your post series and parallel. I have 2 tidalforce wavecrest I want to use these on as a b battery pack. They are a 40 amp hour battery motors at 36 volts. I have a cycle analyst and I thought I could limit the MPH and change the controller. What to you think?

vardi47 1 year ago
@vardi47
You probably have to stick to the controller designed for use with those motors. If it is designed for 36 volts, you are stuck with it. It does not matter what battery you use as long as it is 36 volts. The motors could probably handle 72 volts but you are limited by the controller's max design voltage.

The Dewalt 36V batterypacks use 10 A123 technology Lithium-ferro-nanofosphate 2300mAh cells in series. Wired for 72V-35A of continues use, we're talking 3.4HP, that's moped power, on a machine that weights less than a fifth. I guess we're going 40mph+. If the gearratio and motorcombination allows it.
But that kind of speeds eat batterypower, so, that explains the short range on 4600-6900mAh. Get the gearratio right for 25mph, and get an hour of freedom.

You can but I would advise you not to use them if you have to ask how to install them. They have an internal fuse that can blow and you would have to repair them yourself, Dewalt does not repair them or even sell parts for them. You can buy other lithium batteries for ebikes off the internet.

@dakotabu I rarely exceed 20 mph but can kick it up close to 30 in a pinch for a short time to avoid cars while on the road. The only thing special about this bike are the batteries. They can deliver a lot of power, don't weigh much, charge in less than an hour and have been going strong for four years now.
biodiversivist 1 year ago
@biodiversivist You said in an earlier post you can get approx 25 miles range.These batteries seem a little low on amp hrs to get that kind of range.Are you wiring them in series as well as parallel for greater range?Any info on range/wiring would be very useful.I love the idea of these batts,but the tiny amp hrs kinda put me off.I will be running a Unite 350w 24v geared motor which will in turn be using the bikes deraillieur gears,so should have loads of torque.Thanks.

I always pedal to extend range. It's a bike, not a scooter. I have no problem doing a high speed 25 mile trip with hills. Range is a function of pedal power, battery capacity, motor efficiency, and speed. My bike, with me riding it the way I always do (fast) has a 25 mile range, no problem.
Two batts are in series and then they are in parallel with two more batts which are in series. Also keep in mind that they charge in less than one hour. I can use them all day.

Can you send me some explicit instructions on how to wire this up for my bike. I just ordered a wilderness 600watt brushless hub motor with controller (I am told it has a 50 amp controller) and have been told it has no problem taking 72 volts. I am going to mount it on a beach cruiser. Since it is my only transport and I need extended range and a quck charge, this seems to be ideal for me. I would appreciate any information you could provide to me as I am quite unskilled in electric. TY!!!

Wind resistance goes up exponentially with speed. It becomes a limiting factor at higher speeds as does pedal rpm. In the video you can see that the extra power comes in handy on hills where you can still do 20 mph, which is about how fast I'm going in the video.

ccaptorchen 1 year ago
@ccaptorchen
Peddle, paddle, petal. Generators are hard to turn, especially when they are charging a battery. The idea is to use the charge in the battery to make your ride easier, not to make your ride harder to charge the battery.
You are probably wondering about capturing a tiny amount of energy using regenerative braking. Although the controller is capable of doing that, it isn't worth the added complexity on a bike.
biodiversivist 1 year ago
@biodiversivist
Tiny amount? My understanding with cars is that it is quite a significant amount of regenerative energy re-captured from the braking.
Why would it be worth it on a car, but not a bike?
Are you saying the the extra weight of the mechanism itself adds more weight that the batteries have to push around when moving forward, so it is not worth it?
2bornot2b1984 1 year ago
@2bornot2b1984
You need special brake levers with switches, which can be a source of maintenance problems plus the battery charging system for lithium battery packs can be complex, monitoring heat, voltage and current flow for each cell. You could damage it with a high current flow from your motor. Let's say you capture 10% of your braking energy, which I doubt. On a bike with a 25 mile range, you now can go 27.5 miles. Is it worth it?
biodiversivist 1 year ago
@biodiversivist
Is it worth it?
Before I can answer I would rather have an actual figure than speculation. But it isnt just about the extra range, it's the fact that energy was used to create dthe forward momentum, and when you simply scrub that energy off with brake pads, it is wasted energy.
My understanding from automobiles is that the recaptured energy is closer to 25%. Now perhaps with that much extra inertia there is more to recapture, but I can't see why it would not hold true cont..
2bornot2b1984 1 year ago
@biodiversivist
...on a smaller scale, unless the technology to do it on a smaller scale doesn't exist, or can not be implemented on a wheel that is the size and shape of a bicycle tire/brake caliper combination.
Everyone talks about how big of a deal and important braking is on these bikes to eliminate speed, it would be great to have a solid system that can turn that problem into an asset.

The only thing left of the original shit bike at this point is the frame.

I did that so I could continue to contribute to the power train at higher speeds, especially downhill. The tires are puncture resistant and low friction, it has fenders, and on and on. The frame seem to be adequate for street riding.
