bafang front motor crossbreak style

[edoug]

I'm a newbie and never even heard about electric bikes until two months ago. I came across crossbreak's thread about two months ago and was so inspired I went out a bought a bafang front hub motor, being suggested as the best option for this build at the time because of power and cost. This may not be the case due to the shortness of the shaft and difficulties of modifying the motor for this conversion. The BPM front hub motor may not be the best option for this build but I would still like to share with you what I did to make it work on my bike, and hope you may give me some suggestion on how to improve it.

With no lathe or cnc machine I had to file and cut things by had.

As you can see from my imperfect filing it wobbles. I am waiting for crossbreak to remake his adapters and hopefully it wont wobble so badly.

The shaft adapter can be upgraded when time allows to eliminate the wobble, but so far...looks good!
