  • i have an electric bicycle using 48 volts motor from china as soon that i plug the battery on the controller theres a spark produce on the wire or plug,which will burn the plug on after a while .probable cause of condenser in the controller.are the kelly controller smooter on contact.thank you,gordon

  • dang this is amazing! I would love to attempt something like this on my 250, but I need it to go at least 80mph.. I would definitely do this if all I used it for was driving around town.

  • Whats the range with the new 60 ah batteriea from china and how much did u pay

  • I keep waiting for a gearchange!!! I guess a gearbox would create too much drag to be worthwhile, Nice looking conversion well done

  • the way its geared now, 65

  • what is the top speed

  • I didn't do it for mpg....even though it gets the equivelent of 400 mpg. I did it for fun. I have a YZ6 and Z400....luv gasers too.

  • Nicest cleanist looking conversion I've seen so far. I have a 500 ninja that gets 62 -68 mpg depending on how I ride. I've always been pretty happy with that.

  • Nice bike.

    1:50 - That wasn't a nice driver in that car. Some just can't find the brake pedal timely. Just when he / she's before you already. =/

  • WOW .With the greed of oil companies and gas coming close to $4 a gallon this summer of 2011. We need more vehicles like these. Great Video. Are you from NJ?

  • @joseabreu00 I wish we were paying the equivalent of $4 a gallon over here in europe.As it is, we are paying a touch over $8 per u.s gallon at the moment when you convert euros to dollars.

  • i'm going to convert my 250 too...it's just to much of a gas hog

  • An electric motor has very high torque. Belts are less effcient then chain drive due to tension and friction.

  • @drz4000 did you consider keeping the gearbox and driving the original crank with the motor?

  • @sscholle333 No need to. An electric motor has much higher torque then a gas engine. With one gear I can has fast acceleraion and 70 mph top end. Gearboxs are torque multipliers....required for a gas engine. True a gear box could extend my topend..at the expense of very high current and poor range.

  • @drz4000 You nmean that adding a second, higher gear would consume more electricity?

  • @PktMma Yes, because of the resistance of air, the relationship of speed and power required is not linear. 50 mph uses 50 amps...100 mph used 175 amps.

  • How about using a teethed belt instead of the chain since it doesn't transfer that much power(torque)?

  • Clean, Green, Mean Machine.

    Great Electric Ninja. EV is the way to go. I wish I could do this to my EX250R-2008. Nice Video. Thank you.

  • This is a cool thing . I see that everybody is talking about charge or battery life . Why haven't you modified a small alternator off of a car to charge ? That would be my next step to make constant power off of the chain . How is the acceleration and top speed ?

  • @bigcotie The problem with that is you use more energy then you make....so you would lose range. Perpetual motion is just not possible.

  • @drz4000 it is , in one way of looking at it , when you are able to install a small wind turbine electricity generation system to constantly charge the batteries when you choose that charging system to be active on the fly..manually adjustable :D can you say" free at last?" i knew you could. this will take time and many people getting it FIRST wrong..to finally get it right. THEN we can flip off all the FAKE republicrats and democans in office the past 40 years. cheers! long live free energy

  • VERY MOTORCYCLE MAN.

  • As fun as it is to listen to the motor whine and watch the camera shake, it sure would be interesting to see the guts of this conversion with maybe a little commentary.

  • That is one sweet ride!!

    If I was still working full time, that would be perfect for getting to work in the summer time.

    It's only 10 miles roundtrip, so recharging would be a bit faster..

    Congrads on a great job..

  • guys this is cool that you are doing stuff like this i wqould love to try out something like this to, but still i can not imagine my bike without smell of gasoline without gears and ofcourse without sound,,,,

  • @sxetheexile Agreed, there's nothing better than that petrol-ey kind of smell when you first open the garage. And whenever I hear the engine on this video start to sound strained, I expect to hear him change gear, lol. But still, the guy has done a good job and made an epic motorcycle...

  • Is it possible to capture the regen energy into capacitors for immediate use in your next acceleration cycle? I'm not an engineer, obviously, but it seems you can generate energy a lot faster than you can pack it back into the storage medium.

  • @tomasdipagio Sure, thats what it does now....on braking 50 amps goes into the pack from a 50 Mph stop.

  • @drz4000 Doesn't the energy regeneration mess up the battery's potential amount of recharge cycles? I'm considering building an EV out of an old ZXR, but not too sure if this regeneration is all that healthy.

    Those Lifepo4 batteries are too expensive to risk having to replace them every 2 years, so I'm really not sure if I should go for a controller that allows regen or not.

  • @XSaenen No, you can program the controller to limit max regen current. Mine is at 50amps.

  • Kelly regen applys a charge but its not very useful under hard short breaking; its only effective applied lightly over long distances like rolling hills. The motor can generate a lot of power when breaking from 50 to 0 but lead acid batteries simply can’t charge that fast and most of the energy generated is wasted. Seems like it would be more efficient to store the charge a capacitor bank as you mentioned and then dump the charge upon launching, but probably expensive so....

  • WELL DONE M8

  • cool how far can you go between charge's ?

  • Good job dude. I have a NSR250 frame and wheels sitting around that I want to do this too....Though living ruraly I really need more range...

  • @14212288

    I have 24, 60AH Lifepo4 cells on order....delivery from China early May. This will more then triple my range and reduce weight.

  • @drz4000

    Wow, please update when you get those in. 20 miles would do me for around town, 60 would be even better. Unfortunately I could only ever use it for around town. To get to the city it's a 200km round trip....:(

  • pretty neat!

  • How long does a full recharge take?

  • love it man ;)

  • shouldn't you be getting more miles out of it if you're using regen braking? nice build :D

  • Regen is only good for about 6-8%. Its nice to recapture this energy and save on the mech brakes

  • Top Speed? where you get the motor and electronics?

  • Nice ride.

  • really nice man !

    1:52 he was like 1 meters in front of you :O (the VUS) what the hell .

  • I now use the tach as an anolog voltage meter. Using V/F converter.

  • dude you forgot to hook up the tach? lol jk.. sweet conversion man!

  • GREAT JOB!!

    People, google is an amazing tool. google "DIY electric motorcycle" and all kinds of sites with plans and info pop up.

  • Nice job! Why will the Motorcycle manufacturers do these? The technology is here, with better batteries and chargers these will become even more attractive.

  • What is your estimated weight? And any cost or assembly information that you can provide. Thanks

  • Great conversion!

  • Thanks for the inspiration.

    What type and how many batteries?

  • Great Job !! How much did the conversion cost?

  • The eROCKIT has a top speed of 50mph and a range of 60-80 miles...but it costs $44,000...

  • what are pros and cons of gearing it more for highway?

  • does the regen make a noticible difference?

  • I'd rather have both....like I do.

  • whats the engine braking like?

  • Great, from a 40mph stop, 60 amps is pumped into batts. No need to use mechanical brakes once over 3-4 mph.

  • sounds just like mine :)

    I'm running a Mars brushless motor and a Sevcon controller, which sucks a bit. I need to try a Kelly brushless controller on it.

  • Nice job mate! >:)

  • Can an EV bike get a range of 50 miles on the highway?

  • What kind of range does the bike have and how long is the rechage time?

  • 20 miles with present agm batteries. 35 ah.

  • Great Job!!!

    What was the total conversion cost and where did you get the components?

  • no, velco'ed the cam to the empty gas tank. thats why the regen sounds loud....tank is like a speaker enclosure.

  • pretty kool there phil...was that an helmet cam or did ya hand hold while cruising about???
