2nd hand LEM-200d (double magnets) brushed motor from Asmokarts, rated
at 11kW continuous, 18kW peak output power @ 60 volts.
Drivetrain Motor mounted on the swingarm drives the rear wheel. Chain
and sprockets, direct drive 11:75

Oversized 600A controller to ensure performance without overheating.

Just for testing the concept, I will swap this heavy and toxic battery
pack with modern Lithium cells.

Heater ride hard and you get warm.

Depends on gearing, it's adjustable 50-130km/h
Acceleration Not measured. Feels stronger than the original internal
combustion bike!!

Depends on many variables. 30-40km with lead-acid batteries.

360 2nd hand motor
400 electronic motor controller
390 lead-acid batteries
300 electrical stuff
300 mechanical stuff
250 misc

I sold the old gas-burner for 500
I will invest 1000-2000 on lithium batteries in order to improve
range, performance and safety :D
Additional Features 35W HID Xenon headlight and LED tail light
(efficient and powerful)

I feel like a criminal riding my silent, zero emission vehicle, people
are going crazy...

Stupid spanish bureaucracy makes nearly impossible to legalize the
conversion, I ride it at my own risk...
