After testing the original motor, it proved to be too low in torque at low RPMs, meaning unless I gear it down a lot it will be pretty useless in power.

Instead, after much thinking of Ideas, I looked around for a more suitable motor. There were some perfect for the job, but the cost upwards of $300.

I then decided to spend a little extra and buy an electric conversion kit. I found one online for $395.00 (Australian) which Included:

– 500W/36v Rear hub motor, wheel & tyre
– 500W Re-Gen Braking controller
– Throttle control
– Battery gauge
– Re-gen brakes
– 36v Battery charger
– All needed wiring

No batteries included, so I bought:
– 3 x 12v SLA batteries $90.00

Main installation took about 3 hours, and then another hour for minor changes (such as a kill switch) etc. later.

Next video I will give a test run of the bike in action. It will take off without pedalling, it will even go up hills un-assisted! Here are some basic stats:

Top speed: 36km/h (22.5mph) no pedalling
Range: 20km no pedalling
Power: 500W / 36v
