That's a really cool set up KC.
How is the performance for that set up because I bet it's a blast to ride.
I recently moved my battery from a rack to up front and that made a huge difference in handling. I just wish I could fit one of those battery on my bike.
Well yours is pretty cool too!
You went with the rear electric hub correct?
Looks ideal for that bike.
Where to put the batteries is always an issue, on a 2-wheeler anyway.
I built 3 electric shifting trikes and had huge LI battery packs made that would fit in the case I found to mount between the trike frame and basket with everything in it, even the charger, a keylock, and 3 12V back lights to run of their 36V system.
Point is, I like motor gears, regardless of power source.
The Sick Bikes electric kits have the main good parts you need for $400 if you want to tie into your bikes gears with a good electric base and drive system.
NOTE, the only different part between the 36V and 48V kit is the throttle as they are voltage specific.
The motor and controller will take most anything you care to throw at them, and where you care to mount it is up to you.
On the mountain bike I had no choice but to mount under the down bar.
On the trike I could put it where it fit best and out of the way.
On this 24" 3-speed build for a petite gal, a little $375 36V LI battery system worked just dandy with the motor in the cavity.
Fitting in the cavity can work though, even if you use a big ass battery meant for trike in a 2-wheeler like this one.
And of course if you don't really need to travel far you can get away with a smaller battery and mount everything in a tight package that, well, you get the point.
I like electrics, I like using gears with any motor, this is how I get both.
