Here is a quick all purpose bike I am putting together.
Reason for build:
I wanted an all weather go anywhere type bike. I currently ride a friction drive road bike most of the time. This is great for commuting style riding on the roads and in fair weather, but not ideal for wet weather or off road. Previously I did have a high powered/high speed full suspensions direct drive hub motor bike, but it was a pig to pedal when the juice ran out. So ....... since I only want 40-45 kph cruise speeds I am happy to loss the rear suspension. I want to be able to take it off-road, handle any weather, and still pedal well so the geared hub was the answer for me. Settling on the Bafang BPM based on the positive experience of fellow Melbournite's full-throttle and Kepler.
Ingredients:
- Hardtail Mountain Bike
- Avid BB7 disc brakes
- Bafang BPM Code 12 (supplied by Ben Moore a local suplier in Melbourne)
- EB306 - 6 fet sensorless Xie Chang/E-crazyman/Infineon controller with IRFB3006 fets [EDIT: Corrected fet type]
- LiPo 15s using 5s5Ah 20C Turnigy packs
- Left Hand half-twist throttle - to free up right hand for front brake and rear derailleur duties
Final Product:
~ 21kg
~ 30km range
~ 40kph cruise speed
~ 1500w
