Hi im planing on converting my Genesis croix De fer with a Tongsheng TSDZ8. I was wondering hiw much clearance there is between the bottom bracket and the motor. I.E for gear cables. I've attached photos for reference. The cable guide is 9mm high from BB

On my one, it's about 6mm. There's a slight swelling of the BB of maybe 1mm, so if you have a thin BB tube, you might get 7mm.

Try it, and if there's insufficient clearance, which will probably be the case, run the cables in an outer around the motor. That's notexactly a big problem to do.

With my tsdz2 my brake and gear lines don't fit between the BB and motor.
