Kepler, have you played with the skateboard hub motor yet? Is it still too slow, even with higher voltage?

Re: Gear Sensor for Bafang BBS02 Mid Drive *+ other mid-driv

Isn't the response from the GS (with a dedicated controller input) supposed to be much quicker than a tap of the brake lever?

I thought that the whole reason why the GS was invented was because it takes too long for the brakes to cut and then reapply power (plus the convenience factor).

Re: BMSBattery Torque sensor

Has anybody tried an after-market torque sensing system that was actually significantly better than a modern PAS system? I've added a BeamTS torque sensor, which, when combined with a modern PAS system, has significantly improved my throttle-less experience: https://endless-sphere.com/forums/viewto...

Re: KT-LCD3 speed sensor turns off when motor is not on...

If there is no speed sensor, then yes, the speed will be computed from motor speed. (This is why it shows 0 when you are coasting). Also, I believe that most of these KT controllers shut down when they get no speed sensor input for 5 or 10 minutes. If you can't add a speed sensor to your controller,...

These symptoms indicate that you are either not using a speed sensor, or the sped sensor is not working correctly.

Re: PAS skips - troubleshooting

Grab your magnet disk, and try to turn it on the spindle to see if it's tight. It may be that the disk is rubbing on the bottom bracket, and is not spinning as you pedal.

My solution for access to work on the front wheel was to use longer wire routing, held in place with Velcro wraps.

Re: PAS (Pedal Assist) is slow to disengage the Motor

Again, if you're looking for an excellent PAS experience, get an S12S controller, and use it in torque simulation mode. This lets you control the maximum power by adjusting the PAS assist level. I use one with a MAC 10T on the front wheel, and a 50V battery. Because it's on the front, the traction i...
