I've only used the Bafang ones but a mate who does conversions is looking at getting a TongShen to see how they go. Can reccomend this mob, decent service and best price.Thread dig again.
I'm thinking of dropping a mid drive motor on the child-carrying bike. Urban riding only. I don't intend on going fast, but sometimes I need a bit of extra oomph to get up some of the short but steep hills around here.
Does the TSDZ2 still stand as a good, affordable option?
Would it be suitable to use if I went completely insane and got a cargo bike? (box up front type)
Ideally I want to put my old car to rest and ride everywhere. With two kids. In a car-centric town. What could possibly go wrong?
