My first mountain bike was a Peugeot Canyon Express, from the 80's. A bit unusual, with triple butted cromoly tubes and brazed lugs, Shimano Deore BioPace chainrings and components and Suntour Roller-Cam brakes. Specialized Crossroads II tires. Eventually I gifted it to my son and he used it for transportation. Crashed, ignored, etc.
So it is sitting here in the garage, barely functional, and the pile of e-bike components that I've taken off my bike has grown to the point that we have pretty near a complete kit.
So it is time to make another ebike, right?
There are a bunch more photos in the album here:

So this afternoon we drug out the parts and did a little fitting. The main thing fitted was the 9C 9x7 hubmotor. This JUST fit into the dropouts. Very small but STEEL. On the derailleur side I had to tap the axle in with a mallet and plastic rod. I doubt if a torque arm is needed, but I will fit one anyway on the other side. I put NordLock washers on the derailleur side, since that was easy. On the wiring side the connectors are in the way, so it will get a regular washer setup for now. This axle is really tight on the derailleur side. The derailleur hanger is one piece steel, not removable. Changing tires is going to be an at-home deal. There is a Marathon plus tire on the wheel so perhaps it won't be soon that we'll be fixing flats. I hope.
A friend gifted me a Crystalyte battery box without the mounting bracket. Nice box, have to find or make a mount for it. It will hold 4x5S 5AH Lipo or 2x5S plus 2x6S for 10S or 11S by 10AH. Not a huge pack, essentially 36V 10AH, but quite nice, and very easy. My son doesn't want a speed demon, and with these brakes and his experience level now I'm not planning to push the speed up too high. The controller is 36/48 volt 35 amp, and the battery compartment won't hold more than 11S of the 5AH batteries anyway. So later we can up the voltage a bit, but it will require a different battery setup. Could reduce the amp hour capacity perhaps and find another combination that fits in the box. I actually already have 10S 10AH batteries (4x 5S 5AH) already so we'll go with that for now.
My son already put the thumb throttle and grips on. I guess those are the important things.
The roller cam brakes are in need of minor overhaul (cleaning and adjustment) or replacement. There are no disc brake mount tabs on the frame or forks. The shifter was already 6 speed, and it almost works. It probably needs new cables and a bit more adjustment. I'm not sure it is going to make the super-low first gear though, when it goes there the derailleur scrapes the motor housing. But at least the indexed shifting lines up fine, unlike my bike (even after purchasing shifters mine still doesn't quite line up).
