Anyone installed an e-bike motor on road bike with disc brakes? If so, how did you mount the magnetic brake cut off sensors?

hall sensor and small magnet triggering this hall sensor are are already manufactured into brake lever, you can buy it.

ZeroEm said:Using a push button. Use it to cut motor and engage regen (throttle is moved by the palm of my hand) in place of rear brakes (no rear brakes). Have dual front disc on one dual pull brake lever for the front. I use the palm of my hand so I can grip the hand grips and move my wrist to vary regen or use throttle. Saves my thumb for thumbs up. :thumb:
Monte said:Here's where I glued the sensor on mine
Magnet is inside lever on the hinging piece which moves up and down when pressing the lever in and I could never get a good picture of the placement.
Anyway, the setup was very sensitive to placeme and only worked well for a while. Once the lever sagged a bit and didn't return to quite the same position anymore, it wouldn't release the cutoff.
I have 4500km on this bike and during this time I've first removed one brake sensor, then the other and have now installed a push button on the face of the lever instead.
If you figure out a better placement for the magnetic sensor, I'd love to know as well!

Would seem like it would be more likely to work.

pushbutton? hmm
sometimes you have only seconds to engage brake.
pressing pushbutton would have to be very strange way to engage regen braking

For me, the pushbutton is actually on the lever and will be basically be pushed anyway when applying the brake.

that is how typical ebike brake lever works
beauty of any ebike is regen which saves pads, also on EV.
also listening to those disc/pads noises ...
I must say I use pads grinding only for emergency breaking.

raylo32 said:Yes, fine. But why are you posting that in MY thread for mid motor cutoffs?? LOL.
