very neat build. You have not tried to mask any part of it which I like the most . I bought a 2002 Hayabusa without engine. starting work on that this week. Your work is an inspiration
You evidently did a lot of research on this project which gave you a great clean & compact conversion! I have the exact same hub motor which I plan on using to convert my 1972 Honda CT90. Would you possible share the info for the rear brake you used for you conversion?
@rptrower I got the rear brake from QS motor with my motor order. If you contact them, they may be able to ship you just the rear disc and caliper that will fit your motor separately.
I'm liking the conversion! Though a few thoughts if I may. Why a 3KW vs a 5KW? Was it cost or was range more the priority over speed? I like the addition of the charger, you see that on several factory built cycles but not so many conversions. Have you thought about moving it into the what was once the fuel tank? That way it would be protected from the elements and it opens the possibility of using the gas cap area as the location for the power cable. Anyway this is a fantastic project, and you've done a great job!
@ebikeengineer The goal was to keep it under $2K. A 5kW motor was certainly possible, but the next size up motor, controller, and BMS would have bumped the build cost up by ~$500. Performance would have certainly been better. The nice part is all these next size up components can drop right in with no mounting modifications if that's ever desired. The cross section of the fuel tank is a horseshoe shape, so unfortunately the charger won't fit. Not much would fit in there honestly. Maybe the DCDC converter and some wiring. But there's already ample space for it underneath.
@@zuccamachine You make great use of the existing space, I was just thinking weatherproofing. Yeah a U shaped tank would mean you'd have to disassemble the charger to get it to fit. But you got me thinking how I could install my charger on my Goat instead of carrying in my pack.
The controller supports regen braking. It is on/off only and not variable. You can either use a momentary button to control the regen, or use an option in the controller app that full regen applies when the throttle is released. This is similar to single pedal EV driving.
@andrewgrimm7715 Most people will order a battery from Amorge that fits their size restrictions. Go with a battery that is just as wide as the engine was between the case covers, and fit in the biggest square you can. Just be sure that if the bike falls over, the battery won't hit the ground in any way and is protected.
Nice build I got one similar but I used the fuel tank to store controller and transformer. What kind of controller is that?… my 72v 3kw hub peaks at 45mph and cruises at 40 mph only pulling 30 amps it has more juice but I think the bms is restricting it. I know the mtr controller isn’t
Lovely, hopefully you installed one of those slip-on battery cable terminal covers.
Fantastic build
Nice build, neatly done. Thanks for sharing!

Love it!! Looking to do a 1974 ty250 trials bike in the next year or so.

I should have watched longer - as you later answered my question on the 3 vs 5 KW motor. ;-)

Hi,
I relly admire the work!!
Im wondering how did you do the regen braking, does the motor come with it presetup?
The controller supports regen braking. It is on/off only and not variable. You can either use a momentary button to control the regen, or use an option in the controller app that full regen applies when the throttle is released. This is similar to single pedal EV driving.
Great Project! Have you thought about cutting the cutting the old gas tank open and use it to hide the charger?
@@lorenzglettler9070 The gas tank section is shaped like a U and wraps around a frame member. The charger wouldn't fit.
Hey I'd love to hear more about the battery! I'm about to do something similar on a dt250

Can we get a video of you riding it?!
