Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

My old controller about 10 to 12 years old stopped working. I got what was to be
an exact replacement. All wires was the same. Hookup was easy. Then did a few test
and all seemed good. So did a drive test and it when very bad. I was at 5MPH going
through the big gate started to back off throttle and went to 45MPH. Hit the speed
bump/dip and went airborne. Landed on my right side then E-Trike landed on me.

Well I have a few fractured ribs and clavicle. Yup lots of pain in many places.

So while I heal-up I'd like to make something to limit the power going to the
front 3 phrase motor.

The controller has limit wires set to 28MPH that failed to protect me.

My son said I should move the throttle to a pedal on the right and a 3 switch
cutoff pedal on the left.

Bike is an adult Schwinn trike with back and front facing cameras. "great for nite"
A MM170 with 4" display showing state of 48Volt LiFePO4. While I'm down looking to
change for a newer Pico with DVI and 10" screen with DVI, VGA, AV.

One last thing would be to stream the cameras to my android phone motion detected.

Looking for ideas here.

THANKS
