Hi All,

I have been interested in building an electric motorcycle for awhile. I have been riding enduros and hare scrambles for the last 10 years fairly consistently in the B/C skill range and currently ride a Beta 300rr.

My plan is currently on a 2005 CRF 250R:
  • QS165 60H
  • ND961000
  • Amorge CRF 450 Battery 96V 50Ah RS50 Cells

Below is how that is all kind of laying out. The 165 motor kicks it up a bit compared to the rest of the 138 builds I have seen. I would have the cables exit out the rear. I also believe the battery case would potentially poke through the top of the fuel tank so i may have to design and print/fabricate the finishing cover.

My target use case is:
  • Riding around my parents property and ohv areas.
  • Competing in Hare scrambles, 30 miles ish 20-30mph avg
  • Let my friends ride it and be wowed
  • Stretch goal, Competing in short enduros 40-50 miles, The long ones are 70 plus and will be done on my 300 18mph avg plus higher speed transfers
  • Stretch goal, Commute to work 20 miles on surface streets if i figure out a MC title route. 55-60mph range
I arrived at 96v for better high rpm performance for potential commuting. I also have built and flown FPV drones and the difference between 6s and 4s is fairly significant and i could only imagine a similar level of performance increase. Amorge also didn't really seem to care on pricing between the voltage levels. So the main cost was the controller.

One of the main things i love about my 300rr is the low end so i arrived a the 165 as a higher torque option. I also was influenced by the dust moto using the same motor in there prototype bikes.

As I was preparing to spend some money and get out the mock up phase i began question if i was over building a touch and if the qs138 is all i need for my use cases and could make the build a touch more clean. Does any one have input on the clutch style pop on the 138 vs 165?

Appreciate any input.
