I stuck a bafang on my surly big fat dummy. In terms of installation it was a piece of piss. Main challenge was mounting the battery but I think the internal triangle of the BFD is smaller than then that of the regular Big Dummy, so I expect you probably won’t have the same issue. I didn’t bother with the gear change or brake sensors, as the need for both is dependent on whether or not you have the sense to stop pedalling when you’re braking / changing gear.
In terms of overall range, not sure what I’d get out of it. I’m Sheffield based, so it mostly does short trips on high power up sharp hills. I do plan to take it out into the Peaks for a fully loaded luxury camp out one evening, reckon it would easily make it there and back again if I resisted kept the power low and relied mostly on pedal power.
Eejit-
whether or not you have the sense to stop pedalling when you’re braking / changing gear
I never get this!
I often pedal when braking, particularly when doing low speed maneuvers, through the brakes at a low speed / easy gear. You have more control that way.
if you have a derailleur you always pedal (lightly) while shifting ?
Even with the Rohloff I wouldn’t stop pedalling really just shift in the parts of the turn where there would be less pedal power.
But this was with bosch that has a torque sensor. So maybe not really possible in the same way without.

Any pictures?
Does it have disc brakes?

Looking to buy a Bafang mid-drive to put onto a Surly Big Dummy + Ted trailer. Prob pulling 150kg max, hydraulic disc brakes if that makes a difference for the sensor thing.
Any advice/pointers - or is there an existing Bafang thread? - from folks who have bought/used them? Or where to order? Thanks in advance!
