Missed this. Sorry.
I took my bike along there, left it for a couple of days, came back and it had a mid motor fitted with the cranks and bb and stuff, and the originals we handed back to me. It’s not gone wrong in the year I’ve had it, new chain though.
Do BesBikes have all the Bullitt rear wheel components? I was thinking I'd be going to SBC or London Green Cycles for that.
