I severely sprained my ankle ebiking off road today. I was testing my 3000 watt mid drive and as I was coming up to a sharp corner I slowed down using both of my brakes. My rear brake has a throttle cut off. I did not realize that I still had twist in the throttle when I let go of the brakes. 3000 watts was immediately pumped into the mid drive and the bike flew out from under me. I landed hard and now I am down for the count for at least a couple of weeks before I can hit the trails again.
Has anyone else had problems with the brake cut off acting in this way? It is all well and good if you have a cycle analyst that controls torque under full power for twist throttles, but that torque control is negated once you activate the brake cut off. If you forget to throttle all the way down before your brake cutoff disengages you will get whatever power level your twist throttle is set at all at once. This is dangerous!
I want to know if anyone has come up with a solution. What I am thinking is maybe adding a logic circuit that forces you to go to throttle zero after you have touched the brake cut off before you can throttle up again.
Or maybe a circuit that makes the cycle analyst see the throttle as zero while you have the brake cutoff engaged allowing the cycle analyst to control torque as normal if you let go of the brakes while still having twist in the throttle.
Long story short, I can not trust the cycle analyst or the motor controller to safely cut off power while I engage the brakes. I need to find a way to be able to safely let go of my brakes at any time without the chance of my bike flying out from underneath me. Can anyone help me?
