Upgraded Electric Bicycle

[89JeepXF]

i would get another bracket and mount it under the seat and wire in a general motors one wire 110amp alternator and drive it off the rear wheel...that would increase the range alot further and charge the batterys when not running the motor...and maintain a charge while running...just a thought ...

[mrmihov85]

watch ``Bojan Mihov - bicycle reverse driving``

[TheVideomaster2012]

good

[karim26karim]

this is motorbike not biycycle !?

[shinelectrical]

skip to 2.22

[gerasimoskolovos]

ok 

[den2003]

Very neat!

[Lampasable]

pero ahi si o si tenes q pedalear igual porque esta puesto en el plato donde estan los pedales....o hay algo raro ahi?

[motormx]

wow thats....... pretty gay

[anttt69]

Did you have those parts custom made or can they be bought?

[VLADIMIR87831]

Какая максимальная скорость?

[deathbytacos23]

I like Steve's better:p

[ElectricCarVideos]

Did I hear 350 watt motor? In Australia, we are limited to 200 watts for power assisted bicycles. What is the power limit in the UK?

The pulley arrangement is a nice set up. With the drive shaft on the motor, is there a v-groove pulley or do they have teeth/splines that match the v-belt or toothed belt?

[icarowaki]

nem pro space que niguem vé....kkkkkkkkkkkkkkk

[PrototypeNo97]

haha! what a joke! XD

[badslabber]

so is the motor for pedal assitance ?

[dkw12002]

Looks incredibly dangerous with the belts and pulleys not closed off. Obviously this could never be marketed.

[1355marcus]

I like your pronunciation, very clearly and that I speak spanish. When did you get time to do this project?

[NITECOREPD]

wow the wife sounds like a guy llool

[NicolaBurrow]

@NITECOREPD Have you not heard of a tripod before? Well, its quite an easy concept to set up a camcorder on a tripod and to do your own commentary all at the same time!

[NITECOREPD]

@NicolaBurrow i shud have said it was a joke

[boltenloozen]

that is a nice setup. good work.

[danosly]

all you need now is a chain wallet a tattoo and a leather jacket and you could start a biker gang hell's pusseys

[cscchua]

wow, there is a very huge rotary encoder installed. which model is it?

[produKtNZ]

The average athlete puts out , say around 1/4 horsepower. Assuming that we commoners would put out less (if it were measurable) - could this setup then be considered as a 2 person bicycle? once again assuming the output of the motor (less torque, which just makes things difficult to calculate) is around the same as what we could put out.

[ravingking]

its looks shit and he sounds like a rite amateur faggot

[crackerstolemybike]

@ravingking fuck off you pathetic cunt

[scrambler77]

Dangerous.

[ShazamVanBane]

has any sexy brazilian women with perfect asses and boobs suddenly taken their clothes off when they saw this? pleeze let me know

[taynanliani]

Music ?

[BASSHEAD1994]

if you dont use the motor can you peddle and charge the battery turning the motor?

[ZEINSTAIN2011]

better you check my bike!on zeinstain2011! this is to much pedaling!

[telorinodelhoyoo]

be careful with your balls man

[misium]

With the dive belt unprotected like that, the thought of a shoelace or a part of pants getting pulled in there with the force of 350 watts gives me creeps.

[misium]

When looking at some electrical bicycles here In Sweden, I found out that the pedals need to be turning even when assisted or else its not a bike but a scooter (you'd need a registration plate and a drivers licence).

[GodlessPeaceTM]

Don't get caught up in the pulleys ,that's all i can say :/

[benscardude]

Ok. Either pedal or use the motor... Not both

[NicolaBurrow]

@benscardude The whole point of the design is that you use both 100% of the time. This means that unlike most hub motor types you are not restricted to a top speed of 15 mph, anything above that speed would then be entirely dependant on the cyclist.

[EEEEEEEEEEEEEEEEE434]

@NicolaBurrow when the motor is off you would have to use extra watts to get motor round

[787brx8]

@NicolaBurrow We don't need the government holding our hands and imposing laws that limit the speeds of electric bicycles. Just build an electric bike that can do 60+ MPH and let it run on the road like a motorcycle.

[sn0wchyld]

@benscardude one question... why?!?!

[4crevis]

So you can't free-wheel with it when the electric motor is running the show???! You have to pedal the whole time... that doesn't make sense... sort of defeating the object!

[hooligan11392]

nice town!

[88bobo111]

What is the voltage of your system?

[NicolaBurrow]

@88bobo111  24v

[1BlubeTube]

Now he needs a generator to keep it going for along time.

[pedrosalas76]

I think that there is some way to make to put the motor at the axis of the front wheel.

[nolanpoepoe]

@pedrosalas76 that's called a hub motor.

[1weside]

impressive motored bike i saw how fast you were going.this could be the future of all vehicles . quiet.no police to worry about. wonerfull job sir ,really you are very good at this thanks

[DINGBATDAVE1993]

It's not the wrong side of the road, the US drive on the wrong side, in the UK we hold the wheel with our right hand ( peoples predominantly stronger hand) and change with the left, steering with our stronger hand gives us more control of the car, this is why. But hey most Americans have automatics, wouldn't want them to get their brains overflowed!

[photofreaksk]

I can see you still ride on the wrong side in UK...

[eddiequest4]

Looks like someone needs a tripod... :-P

Neat idea tho.

[scrooty1]

you seem to have to do all the work

[ochgottnochma]

2:22 to see it in action.

[magna59]

Lovely piece of work.......i've been having discussions recently over the lossy nature of 'v' fan belts, which as I understand it can be over 50% if there is a notable difference between the pulley sizes. Feel the temperature of the belt after a bit of a run and know that comes from battery. At one point , you coast , so you turned the motor off to do the turn ? There is a folding bike called the Strider that has a free wheel in the bottom bracket, why may give you some rest on the way home !

[mateyvelican]

thsi is not working! guy at the end of the video is pedaling...!!!

[Hodenkat]

Watch your pants don't get caught in that top pulley!

[Chatthai2534]

Can this bike ride on the steep .

[frackcha]

awesome project, and thanks for sharing :) i had a little thought.... could you use a ratchet (like on the rear wheel of a pushbike) acting on the axle of that center pulley wheel to help........ wait...... no that wont help..... darnit :) still, cool project..... plus, ill wager, a heap of experience to apply to the next one.... we'll be waiting :D

[peppes97]

when you've spent on the engine?

[ThinkStage]

Very cool

To see more innovative videos like this or want to share your own ideas visit ThinkStageDOTcom

[peppes97]

but where did you get the generator

[NicolaBurrow]

@peppes97 you mean the motor . I bought on e bay

[abdellahiarefa]

@NicolaBurrow hello. please tell me aboute the motor : I want one alternative! so can i find a motor in some things..in car or homes tools.... thanks

[NicolaBurrow]

@abdellahiarefa I bought this motor off of e bay for about £30. It is 350 watts there is a smaller one of 250 watts which I used in the original project. I think they are the type used in the stand on electric scooters.It would depend on what you want the motor for. A windscreen wiper motor from a lorry which runs on 24 volts may be a consideration . they also have a gear reduction already built in so that can be usefull .They are probably only around 50 to 70 watts so you may need two.

[NicolaBurrow]

@abdellahiarefa Bear in mind with wiper motors most have a worm gear so they can drive but can not be driven.Also think of motors which are used for long periods. Not for example a starter motor which although is very powerful would soon over heat with continuous use. I hope I have given you some help. Most of what i have done has been trial and error. Good luck with whatever you are building.

[redghost105]

@NicolaBurrow how much did you pay for this whole set up?

[NicolaBurrow]

@redghost105 It was done on the cheap all in for about £150.

[skoalstright]

@peppes97  G A Y

[MultiCunt666]

now that is cool

[slicktires2011]

So your total reduction is about 70:1?? That must give you a lot of torque! How good is it going up a steep hill?

[NicolaBurrow]

@slicktires2011 Actually the ratio is about 32:1 after I made this video I realised my mistake of calculating it using the internal measurements of the pulleys instead of the outside. As for going uphills the motor assists on all aspects of riding but the lead acid batterries are its bggest let down.

[omgsean2]

@NicolaBurrow hmm lead acid batteries are heavy than lightweight battery?

[jonesclan9]

@NicolaBurrow What is bad about lead acid batteries ?

[tsbrownie]

Regenerative braking?

[stevensx7]

Full Moon e mobility EnBW.flv

Look at this, that´s the future !!

[luc59457]

I use the unite motor too, I held 70km/h 43mph on flat with it

[smelter159]

good job. well done

[KokaVirivotaNah]

Электровелик ?

тогта нахрена он крутит педали ? - баран

[NicolaBurrow]

@KokaVirivotaNah Hello, please can you provide your comment in English, as I'm unable to understand what you have said? Many thanks.

[DoctorFreeman97]

@NicolaBurrow I will now suggest google translate.

[DoctorFreeman97]

From my russian classes i believe they said:

*illegible, i think it's near What if you run out of energy?*

Then the second line is "Fuck it, pedal?"

[NicolaBurrow]

@DoctorFreeman97 Thank you. I'd actually used Google translate myself but the results seemed a bit odd, especially the second line about the pedal!

[DoctorFreeman97]

@NicolaBurrow Anytime.

[smelter159]

@NicolaBurrow

He says - he ram, and does not understand why there pedals.

[fairyheli2]

does it add alot of resistance when the battery is empty?

[NicolaBurrow]

@fairyheli2 yes.Its not really designed to be ridden with a flat battery. But if a freewheel was fitted it would eliminate that problem.

[sidvicious020279]

thats crap....

[NicolaBurrow]

@sidvicious020279 thanks for your comment

[crudeoilsystems]

great job

[TimpBizkit]

I've been wanting to do a similar thing with a honda gx50 and a 40:1 reduction at the cranks. I'm not sure how to do a freewheel though so I don't have to pedal against engine braking when the motor is off. I guess I could put a simple manual clutch on it so I can start the motor by cranking the pedals and also disengage to use as a non motorised bike.

[TimpBizkit]

I'd put that on a road bike so I could crank my 52/11 at 80rpm. That would be cool

[cdmharley]

Just dont wear lose shorts... shave your legs and balls before use!!

[BiggRob1221]

was that the motor pushing alone or where u helping

[NicolaBurrow]

@BiggRob1221 the rider pedals as well to give an overall total power

[BBLuVr1]

does your design allow for you to pedal backwards as the bike moves forward, the way a bike like that would work without a motel .... a la ... the "optibike"

Which shows us the optimal placement for a motor on a bicycle ... the bottom bracket.

[NicolaBurrow]

@BBLuVr1  No.

[godmajic]

take ur feet off and not petal so we can see if it really works or some random guy petaling me if it works imma try and make 1

[caddy60special]

I JUST PUT A 66CC 2 CYCLE ENGINE ON MY MOUNTAIN BIKE. HERES MY QUESTION I PUT A RADIO ON THE BIKE POWERED BY MY DIE HARD 12VOLT ATV BATTERY. DO THEY MAKE A GENERATOR SPROCKET TO RECHARGE THE BATTERY WHEN IT SPINS . I HAVE NO WAY TO RECHARGE EXCEPT FOR THE TRICKLE CHARGER. THANK YOU FOR YOUR HELP

[riotact747]

@caddy60special I have seen generator hubs that go in the front wheel. You could look into that. The ones I have seen came on beach cruiser bikes to power lights. good luck!

[IcarusX72]

Where do you buy the motor?

Nice job.

[NicolaBurrow]

@IcarusX72 I bought it on ebay

[motorcyclecushion]

Like your work because it is simple and clean. Would you clutch the motor to eliminate motor drag while pedaling?

Win

[NicolaBurrow]

@motorcyclecushion I did think of adding a freewheel to stop motor drag while pedalling unassisted but didn't bother as I was managing ok without one.

[laxplayer1199]

@NicolaBurrow What did you use to charge the battery?

[laxplayer1199]

What so you use to charge the batteries?

[laxplayer1199]

What do you use to charge the batteries?

[laxplayer1199]

How do you charge the battery? Thanks!

[NicolaBurrow]

@laxplayer1199 the batteries are charged either in parralel with a twelve volt charger or individually.I dont use a 24v charger as although it would probably be ok to charge them in series manufactures dont recommend it . Also they would have to be charged individually now and again to keep them both in sync.

[ihatemuckdjs]

I am starting a job on Monday where they provide training to install these kits! I can't wait to make my first e-bike!

[bangzilla]

get your fingers in there, byebye fingers

[laxplayer1199]

where did you get the motor and all the parts? Thanks!

[flyro2000]

ya good apart for you put good gear on to a rubbish bike but nice why dont you put it on a nice bike?

[NicolaBurrow]

@flyro2000 Thanx for your comment. When I started the project I didn't know if it would work so I did it on a cheap budget.

[flyro2000]

@NicolaBurrow oh ok sorry about being a bit cruel but like the idea, look at ebikes there like a moter bike but electric bye

[ohyeahtotally08]

Very nice! love to see one on a racing bike.

[NicolaBurrow]

@ohyeahtotally08 Thanx for you're comment .Its on my to do list.

[luc59457]

Electric!

[jadayMisha]

мх тема

[sweatyss]

ok. so why cant an altenator or two be added onto the rear wheel to prolong or sustain the battery?

[hotstreak334]

thAT SHIT LOOKS UN SAFE

[salamalycoom]

I like the belt drive why didn't I think of that

[HEMAS13]

all it needs is some guard sfor your left leg

[shukronnn]

why not put the motor on front tire... it,s much eazier..

[ShelbyGT500TT]

i dont know bout you guys but i thought you were sposed to ride into traffic?

[ShelbyGT500TT]

and i know hes in england but still

[NicolaBurrow]

@ShelbyGT500TT i,m sorry but I don't know what you are talking about. I'm following the highway code and also using a cycle lane.

[manfromregina]

@NicolaBurrow hi ,you're pedalling ,the whole time.

where's the motor come into this?

[NicolaBurrow]

@manfromregina the pedal power is added to the motor power giving a combined overall power.

[rsmithlal]

@ShelbyGT500TT Depends on the country or even state/province that you reside in. I know that bike laws have changed a lot here in Canada even since I was a kid. Here in Canada at the very least, you have to ride WITH traffic.

[Rayxl1]

I made a pulse width modulating control system for mine which wasn't too difficult but making an accelerator pedel give a varying resistance is now the problem. Reed switches and a moving magnet is nice and frictionless but gives too much hysteresis and only stepped control. A potentiometer gives nice control but too much friction; but getting round these problems is half the fun of enventing!

[VialensCalaelen]

Ну вы даёте ?! Передачу надо было ставить на колёса, а не на педали!

[walkingfreak]

these bikes would be awesome and when there not in use they charge up the battery when your coasting kinda like a prius

[Jonz6661]

@walkingfreak some bikes can do it, you put the motor in reverse and it acts as an alternator and a brake, or you put a solar panel on the pannier rack to charge it while your in work.

[homemadehookahguy317]

lol farmer voice!

[1204DIZZY]

put a ALTERNATOR on it for the batter it works :)

[TheMikejollie66175]

cool

[35Berrin]

ride it!

[nileor1]

ive always been curious why no one has added a low resistance high output generator to their systems to regenerate electricity back to the battery ? also i have seen other model add light weight 12 v battery in empty space under main support bar, good job though this was very interesting, all you need to do now is figure out how to add auto shift to system and you can save electricity/power

[0urGaia]

@nileor1, motors and generators are not 100% efficient so you would actually loose power by propelling the generator with the motor.

[rainbowdragon1215]

Can you still pedal regularly with these bikes ?

[NicolaBurrow]

@rainbowdragon1215 Most of the bikes on the market have a brushless or ac hub motor in either one of the wheels which can be pedaled without the motor running and can be ridden as a regular bicycle, albeit a very heavy one. Although my home made bike can be pedalled without the motor running the motor puts a resistance on the pedals so unless a freewheel was fitted it is not worth it.

[governator45]

@NicolaBurrow But you can pedal to help the motor out?

[nitrodudez09]

@NicolaBurrow So surely when you are pedalling the bike without the motor on this would charge the battery?

[MrOlezhandr]

Is not it easier to put forward the same wheel as the rear (with an asterisk), and buy a motor with gearbox and an asterisk on the shaft (eg MY2010), instead?

[TaylorHolmes]

24volts*19 amps = 456 watts, dude.

[cyberlord64]

where do you people get these motors. I have searched in a range of 200miles from where i live and still nothing

[NicolaBurrow]

@cyberlord64 I got mine off of E- bay.

[cyberlord64]

@NicolaBurrow how much did you pay for it? how long was the shipment? what was the condition and the specs of the motor? and if you could also add the seller i would be greatly obliged

[NicolaBurrow]

@cyberlord64 I paid about £25 plus £6 postage. Its a 24v 350 watt dc motor which I think are used on electric scooters. It was new when purchased but cant tell you who seller was.I bought it maybe 2-3 years ago and they were quite easy to get hold of then, but just had a quick look on e-bay and only saw 1 250 watt from china with £39 postage so it looks like they are now hard to come by. Sorry I cant be any more help.

[derman077]

@cyberlord64 i helped someone move and he gave me two of them. attached to a pesky scooter but i got it , lol

[cyberlord64]

@derman077 you lucky bastard!!!!!!!!! :P

[derman077]

@cyberlord64 lol, thank you. I worked my butt off for them. good luck finding something. What do you intend to do once you find what you are looking for?

[cyberlord64]

@derman077 I have converted a bike into an electric one about 6 years ago when i was 16 using two 12v motors (taken from a cars cooling fan) mechanicly connected and overcharged at 24 volts each. I managed to get as fast as 55-65km/h (depending on the conditions) but after a couple of months one of the motors burned. Now i want to build another one but as i am heavyer now i need a stronger motor. At the very least 500w. I saw an 800w motor at ebay and i think i will go with that one

[toxicstone]

@cyberlord64

i have one for sale on tradera.com an ebay site

go in to tradera.com and search for El motor till en elmoped 24V DC 200W + Adapter + 2 st 12v i cant link here :S

[sxayaxang]

hey hoe do you control the speed

[NicolaBurrow]

@sxayaxang There is no speed control unit as the idea is, that by selecting the correct gear the motor keeps working at its optimum efficiency.

[NicolaBurrow]

hahaha LOL at your ignorance

[sonicxlc123]

i can get my bike up to 75MPH no joke! no hills nothing just man power the shit out of it i peddle my main speed is 50MPH my slowest is 30-35

[beamo32]

i woudnt like that belt to snap and slap ya testicle hahaha

[DMxNemesis]

looks like he was pedaling all the way with no help loll

[standinwater]

Good idea, but it should be disconnected from the pedals for safety reasons. I'd be concerned at least if it's a good idea to have your knees being pushed around by an electric motor when you're tired and most likely to use it.

[ChowZeb]

What if you get your pant leg stuck in the belts? or a finger?

[xmicina]

@xMackan750x There is direct mount pully on left side of pedals. There should be a freewheel on pedal crankshaft(little bit complicated solution in homeworkshop). I think that freewheel is implemented in electric motor, when is motor on= it adds force to pedal= direct drive(pedal moves). You can pedal with motor(if your back wheel looses traction, motor could spin pedal much faster,does not happend usualy I supose. Big plus is all gear range of bike can help motor work in optimal performance

[pescadinha123]

hope your leg doesn't get cot on the belt !!!! lol

[721069]

I don't see the point of this... a gas bike is much easier to build and cheaper, plus you can go about 50 miles on a tank of gas non stop power. i get 150 mpg on my moped!!!

[xmicina]

@721069 The main point of doing this kind of vehicle is:

if you are on moped and motor refuse to work= you are fucked up 20 miles from civilisation in the midle of nowhere( moped does not have any backup power). Than a turtle is faster than you with a extra heavy bike to walk back home. I personaly prefer this kind of solution(but with small gas motor(f.e. Honda GX 25 or 35 ccm). Electiric motor is more suitable for comuter. Stil can pedal, much easier with motor on.

[721069]

@xmicina well first off i should have said motorized bike not moped.. sorry my fault. How ever my bike doesn't have any problems so i know i will not have any problems!! also if you look at the differences between the two gas is cleaner then electric.... i can go on and on and on but i will not because there's no point. over all gas is better!!

[FilippoGatti1991]

it's too slow... i can go a lot faster with my normal MTB.

[NicolaBurrow]

@FilippoGatti1991 well of course you can you are 19 and fit. I,m 45 and fat.

[SebastianHofmann]

you should connect the motor gears strait to the wheel so that you don't have to keep pedaling with it.....it will make it look more enjoyable

[drsquirrel0]

@SebastianHofmann your legs will just seize up if you don't use them for long periods, and if you pedal at least slightly, you will easily double the distance, it only really draws power when you struggle (hence power assisted).

And at least this motor can make use of the gears for climbing etc, cheap bike hub motors on the front wheel run as if they are in a single gear, which sucks :p

[jeanlucvar]

Wow, really excellent - congratulations,and good continuation in your job

You can also see on YouTube,the assembling my electric bike. Thanks

[crazykawafool]

did u know u were pedaling the whole time

[NicolaBurrow]

Of course . The motor turns the pedals. The rider adds his own power to make it go faster.

[crazykawafool]

@NicolaBurrow ohhhh i see

[bykashka75]

@NicolaBurrow is it DC or AC motor
