I put a tong on my bike a couple of weeks ago (a pashley I bought off @passhunting last year). Pretty simple really, just swap the bottom bracket and wire everything up. Probably took no more than 2 hours. I got my from PSW Power on ali. Came to £400.13 for both the motor and a 48V 12.5amh (if you use the 'ship from China' option, although it actually comes from Germany...). I think coaster brake may be an issue with the tong as you can't acutally back-pedal due to a cluch thing which stops the front cog rotating backward (although the cranks still rotate), I assume to protect the mechanism or something?
That's a good point! Coaster brake won't function at all as the cranks are independent from the chainring to allow the throttle to be used without pedalling
