MY tongshen has not arrived yet
However from my reading if you do not use the thumb throttle you do not need brake cutouts – because the motor stops when you stop pedaling – thats the beauty of torque sensing. My previous kit was torque sensing and no brake or gearshift cutoff – worked fine even with hub gears
My kit is coming with a big battery – 17w amp hr and from a UK supplier who had it in stock – so I paid £650 for it.
I think but am not at all sure that you can use any battery of the correct voltage but am not sure
apparently there are people who can help yo alter the software as well so you can go illegal if you want – ie its the same hardware for 250, 350, 500 and 750 w versions but you ned to crack the casings to do this
I will start a thread when it arrives which should be tomorrow
