Problem solved on mine! I started getting the speed sensor problem on my 2020 Trance E+1 a few minutes after a hard whack on a log on the bottom of the bike-motor cover. I thought I was just running out of battery life after a pretty demanding ride. Ended up struggling out of there mostly without power (waaa). Tried lots of the great suggestions on cleaning battery terminals, etc... and then cleaned magnet on rotor - still would cut out and flash red and the L3 light (speed sensor) with a fully charged battery - after about 10 seconds of power pedal assist. Popped the lower cover on motor and quickly saw the speed sensor cable was perfectly centered over a 'high spot' on the motor housing - and my solid contact directly on this while crossing a log smashed the wire pretty good (see pic). I carefully stripped/soldered/heat shrinked each wire and then the whole bunch (3 wires) and then tucked them down and away from the area where a direct hit on the bottom cover would do this to me again. Good to go now. These bikes are a lot more fun when everything works. Ha.
