Bafang PAS senso
« on: June 27, 2026, 10:31:50 PM »
Hi. Has anyone recently converted their Rohloff-equipped Thorn with a Bafang front motor?
There’s a couple of issues Id like to understand.

The online sales stores (Amazon, etc) offer a left side and right side PAS sensor, neither of which seem very compatible with Thorn’s BB. Has someone fitted either of these successfully?

Also the Thorn dropouts are 9mm. I can’t tell but I imagine the Bafang kit requires 10mm. Has anyone successfully installed this and what was the solution?

Thanks!

On my wife’s hybrid I had to file the front fork dropout to 10mm to take the hub motor axle.   Could you find an older / cheaper fork?

Thanks. Could do yes. I’d rather avoid either!

Filing down is something I could live with.
I’m less convinced that the PAS sensor will fit and there doesn’t seem to be a way to check
