Got turned onto the Bafang motors after years of speculation over powered bikes in general. A coworker let me borrow his Bafang 750W equipped folder for a week in 2016 and I was more than impressed with the speed and range.
I ended up getting a BBS02 and a BBSHD for both an old cyclocross bike I picked up from a yard sale and my Catrike Expedition.
They do get addicting and now I try to go as many places with pedal only and gym trips. I save the motor use for riding on the main roads out here.
