Electric Bike

[kokopelli314]

Is that singulator upside down?

[kdc43]

WHY would you connect a hub motor to the bottom bracket????? Lace it to a wheel and SKIP that extra chain, ratchet and motor mounts. LOTS easier doing it that way!

[robbo1908]

That's a brilliant bit of kit, but I just know I'd jump on it in long trousers and laced shoes and lose a leg

[ez3usx2]

electric is the way to go...

check out the lincvolt neil young is building.instead of plugging it in the recharge u plug it in to power your house.

[jokey444]

hahaha!!! when he opened the battery place, it looked like fucking bomb!!! suicide biker!!!

[jesse19811]

put a larger gear on your rear wheel to get more torque outta that hussy!

[motorpsychohead]

i think this is a great home-made. Can you tell me how and where to get the CRANK like on your bike ? And how much ? I've been looking all over for a Crank like that but never saw until i see this video ! thank you , now I know it exists !

[poobardog]

Hi Motor

Check the earlier comments -you can (or could) get parts from Cyclone USA

Cheers

I think this is a great home-made ! Can you tell me where to get the Crank like your bike ? I've been looking all over for it but never come acorss one until i see yours ! Plsssssssssss tell me how and where to get it and how much does it cost ? Thank you so much !

[ROY0666]

yo, this bike look like SHIT

[jojo808]

Reminds me alot of the StokeMonkey. I recently saw someone use the Currie electroDrive [spoke drive} as a crank drive with only 24 volts! Some how the crankdrive seems like a much more efficient application than a wheel hub or spoke drive to me now. Any reason why?

[poobardog]

Hi Jojo

Yes -my inspiration was based on the Stokemonkey,but i didn't want to pedal :-)

Crankdrive are really good for torque and i find having more voltage and less current is good for your batteries as well.Plus you can get lower amp rated batteries which is heaps cheaper.

Crankdrive is a bit noisier than hub or spoke drive and great for hilly areas.If you lived in mainly flat areas the hub/spoke is the way to go.

Cheers

Dom

[jojo808]

Hmm.. I have the bionx and the Currie spokedrive 24v . The inherent limits are torque and set revs as gears are not connected. Although they're great and I don't yet own a crankdrive , my searches and laymans logic say the overall package is the crank system ,as it assists at any speed as long as one has the gears for it.

[poobardog]

Have you got alot of hills around your way?

There are a few 17deg hills around my place which i regularly ride -that was why i went with the crankdrive.

Otherwise the hubdrive at 48V20A in a 26" wheel was fine -still had to pedal but was good moderate exercise.

Have you looked at BMC brushless geared hub motors for example? Or BMC motor kits that are similar to your Currie?

Cheers

Dom

[buchnermarkus]

Is it what it looks like? ( completely DIY )

The motor seems to be a brushless outrunner.

[poobardog]

Hi mate

Yes -all DIY

Motor is a hub motor with the spoke flanges cut off

[buchnermarkus]

Brushed or brushless?

Does it have 2 or 3 wires?

[poobardog]

Brushless

It is a Crystalyte motor

Now using a 408/4011

[kinsler33]

Yet another electric bike video that doesn't show anyone actually riding the thing.

[poobardog]

I have a couple other vids with it in action.

[christopherdoshoian]

I plan on getting a speed bike frame, then hooking up a high output motor, with a couple alternators to charge a seperate battery or to charge the battery while i am using it.

[Tsnafu]

you are going to use a battery to power a motor to power an alternator to charge a battery? You are a fkin idiot

[Dilekz]

Yes that christopher is crazy.. are you thinking of overunity.. Those people are insane and believe everything without trying itself.

[christopherdoshoian]

But i think alternatornators are better than a petrol motor to charge the batterires. Just because it involves more emagination. And i hate using gasoline. lol

[christopherdoshoian]

I also think it would be very good for a trike. good idea

[christopherdoshoian]

See, if u can tell how many amps you are drawing from the motor, there is hight output alternators. You can put more amps in than u put out. Or u can charge a seperate battery with those alternators while the seperate battery is powering the motor.

[christopherdoshoian]

Would u ever consider putting an alternator or two to charfe a seperate battery while u use a battery, then when that battery dies, u can switch it with the one that was getting charged. that is my idea for an electric bike

[poobardog]

Hi Chris

I was going to use a petrol motor as propulsion and generator to charge batteries for the electric motor,but the bike was massively overweight.

Would be a good idea with a trike i think.

Good luck though

Cheers

Dom

[vinilla]

very good work!

[poobardog]

Thankx Vinilla

Is alot of fun building and getting it working.

Cheers

Dom

[TechnoTempleStudios]

Hi there, curious about your rear hub, is that like those old sturmey archer or suntour 3 speed hubs that were so popular in the 70s-80s only with more speeds???

[poobardog]

Hi TT

Yes ,it's a Shimano Nexus8(speed) -gives a really good torque range for hills and such

Cheers

Dom

[dual85]

I like the way that electric motor is mounted. You have a good setup. Show us a video of your other E-cycle.

[poobardog]

Hehe .

Will have to wait a while as i crashed into a car which did an unexpected U-turn in front of me.

Bike is fixable but have to wait till my 2 broken legs fix.

Cheers

[dual85]

Oh my gosh are you going to be OK? I'm so sorry to here about your accident. How fast did you clock yourself? Here is hoping for a speedy recovery and getting back into action. Cheers man!

[poobardog]

Thanx Dual

Legs are healing well -prolly 3 more weeks and off the stix.

Was doing about 45kmh no brakes.

I'm going to go a bit slower in the future -30kmh would have give me some reaction time.

Cheers

Dom

[poobardog]

whoops - i just deleted someones post.

it does up to 55kmh -though i have the electrics on another bike now.

will have to make another vid

[taterbrain1]

Electric bike from hell. Very Cool.

[roremster]

thats awesome.........

I've never seen one before.

Can it go fast?

[funnyman1972]

You are the first person i could find that shows how it all works.Thanks

[drey27]

the motor you got there isnt that a hub motor? so why didnt u just use that as your rim

[youfuckingtossers]

You mean hub not rim, retard...

[quickstart20o7]

how long do the power last

[poobardog]

I can get around 35klms without pedaling -distance increases of course the more you pedal.

[Dershnof]

Whats the top speed?

[OregonDARRYL]

But why would you not use the hub-motor as the front hub? Don't you add friction with the chain, and expose it to rocks and sand, water, etc?

[OregonDARRYL]

Nevermind... I read a little further... it lets yopu use the gears of the bike. Interesting. But I love the idea of a sealed hub, with no moving parts.

[poobardog]

Hi Daryl

Used just as a hubmotor on the front -it won't get up alot of hills without major pedalling. 99% of hills i don't have to pedal if i don't want.

A "Puma" geared hub is better on the front.

[Jibbie49]

I read that most people would ride bikes if they didn't have to peddle up hill, so the electric motor would greatly help that issue.

[druidg]

very pretty, i want to build the same thing but cant find any freewheel front cranks. i plan on using a currie motor i already have but same drive setup. where did you get your front crankset?

[poobardog]

Have a look at cyclone-usa in miscellaneous parts -you need the cyclone crankset and freewheel adaptor.Will have to rig the chainrings.

[luisbaltazar1]

doesn't the rotor's rotational inertia, at this gear ratio, make the bike too heavy (compared to the original bike, without the electrics) to speed up while using only the pedals?

[poobardog]

Hi Luis

There is a freewheel on the motor and crank -so everything is independent -just like pedaling a normal bike -apart from the weight of motor and batteries.

[Seanisthebest1]

Hey Cool bike but just one question how tolerant is a typical ebike system to crashes and is it legal in the USA, I ask because I myself am considering getting an electric bike. I got a few others but I dont want to overwhelm you : )

[poobardog]

Hey Sean -i'm from Australia -nothing is legal here LOL

There are alot of stealth ebike systems that you can get that are fairly powerful -legality in USA seems to be different in every state.

I've crashed lots - just have to make sure the batteries are well protected.

[cornsnakeman94931]

what is the point of a bike with a motor on it

[poobardog]

If you live in a city -it is quicker than a car, motorbike or pushbike to get around -and you don't have to pay for parking or registration - and you don't need a license.

[OregonDARRYL]

Electric assist let's you go further, faster, with less effort, at less cost than gas powered stuff. It' also let's you feel like you're screwing the oil companies back for once. I like the idea!

[echoanomie]

Hi dom, I was wondering how you made the freewheel - I've got the oatley working, but a crank freewheel would make it much better/safer.

Or - can I offer you money to make me some? :)

[ttt60]

That is a hub motor, why not putting it in the rim?

[poobardog]

drives thru the gears for good takeoff and hillclimbing

[echoanomie]

Cool, I might do that. But how does it perform?

[echoanomie]

I noticed (on power-assist) that you were experimenting with an oatley motor, I was wondering how it performs?? Any vids? :)

(I bought a 300w version - but I'm having trouble fixing it on, I should have got the 250 geared mod in retrospect, but I'm determined to get this working!)

[poobardog]

Hi Echo

A few people have done the 250 geared mod - i respect your detemination on getting the ungeared 300w motor going,but i think it would only be good for a scooter.

Reccommend you get the geared 250!!Much easier!

[canadianhoser]

Hey Dom ,I have an x5 and x4 .All my vids are with the x5.I have 8 vids at googlevideo the latest is labled (electric bike part1 through 4)I started a forum with google groups, you can find the link on my vid page .

[canadianhoser]

didnt let me post a google url

[canadianhoser]

Im Volt from the visforviltage forum(currently looking for a new forum)...are all you vids posted here ? google has a great upload tool that allows you to upload well over 100 meg vids.My latest is over 600meg.

[poobardog]

Hiya Volt -thought it was you after looking at the crash vid LOL

But didn't know you had the Currie.

I noticed you were missing at V -Thought Dicanio went as well,but he chimed in today.

I haven't any vids at Google yet -will after i finish new bike.

Are you Canadianhoser at Google - will do a search -must be a long vid!!

Unfortunately V is the best setup -next would be Yahoo Power Assist -Buzzz chimes in there a fair bit lately.

Cheers Dom

[canadianhoser]

dom ?

[poobardog]

Yeah! Who Be You? Name is familiar!
