Hello All,

I got into an accident today. Luckily, no one was hurt, I got myself some road rash in elbow. Here is what happened. I was on my way to the bart train station in San Francisco to go home, from work. At the last stop, for some reason, I could not slowdown or brake, although I saw that the remote is still connected. I decided to bail and jump off, trying to run a few steps before I landed on the street. Unfortunately, my board decided to continue its journey by itself at the same constant speed. It ended up under the electric bus/train wheel and caught on fire.

There are 2 things I’d like to discuss:

Firstly, please make sure that we all have protective gear, and ride that the speed that we can jump and run off. I’m glad that I don’t max my speed in the city often. Second is a question. What could have happened with the vesc to disable my brake? It has been very reliable board. The only difference between today and other is the hot temperature at around 86F degree.

My board configuration is:

10s4P battery with BMS (group buy)

Maytech vesc

6454 motor

Maytech new mini remote contorller

I setup my vesc to freewheel if controller is disconnected. But I don’t think it is the case, because the controller connection light was always on.

Although I will be boardless for a long while, I’d like to learn if I did anything wrong with my build. Thanks!

My vesc setup:

My board turned into 3 pieces:
