Swordman's Electric Mountain Bike

[Swordman]

Recently I added power assist to our mountain bike to help with hill climbing and when running errands.

I ordered a 24V P2-A geared hub motor, controller, and thumb throttle from Island Earth in Australia and a single 24V 8AH NiCd battery from ebikes.ca.

This design provides a nice assist when going up hills. You still need to pedal to help out the motor when going up hills, but it provides a nice level of assist to help you out.

Top speed with this approach is around 15 mph with an unassisted range of over 10 miles.

You need a cover for the back of that battery if you ride in the wet. The tire will throw water right into the case.

Lessss,

I do have covers for both my bikes. They are made out of a black stretch fabric. However, I thought the picture would be more interesting with the cover off to show the hardware, instead of a black fuzzy block.
