Yep, this is my bicycle. And here I'll show what I'm doing to this poor soul.
First, What I started with
And now what it looks like with a new battery/brains box + recycled NiCd's + and old BD36
At this point the bike works, and I've used it for a few rides. The duct tape and cut up zip-lock bag provide basic rain sealing for now. I'll be painting the battery box and properly sealing it once I get a few more switches and a power socket for my headlight installed. Oh yea, 33.6v 7.6Ah battery pack, should give me ~20 mile range while averaging 12-14 mph. (I'm a slow-poke biker, we'll see how long that lasts
finish up the battery box
better head light (so I can blind the car's for a change)
Up my gearing so I can pedal with the motor
make the motor drive the bottom bracket
P.S. I'll get pics inside the battery box next time I pull it apart.
