    Tell us more. Range? Weight? Top speed? About the wheel/hub motor? Will you add pedals? Going to stay with those brakes?

    I mean a disconnect in case the controller runs away. If (when) I fall off, the throttle spring will just return it to 0. My plan is to put a 30 amp switch on the battery. It will not be switched under load unless there is an emergency. I think that will work fine.
    The motor is 1000 watt Chinese import. The wheel/motor weighs 16 lbs. The battery less than 10. Top speed is about 28 mph. Range should be 10-15 miles per charge without pedaling.
    I just finished the bottom bracket:





    Neither the frame or the forks are setup for calipers so it is V brakes for now. If I use this thing a lot, I may go to disc in the future. I would have to change out the fork and weld mounts on the frame.

    Next: finish the spindle. Change the tire for MTB tires. Start on a cool battery box. Need to find or cast a bullet headlight and a seat!

    I like it. Just put a kill switch on the handlebars. If things go nuts you cut the power to the entire thing before it dumps you.

    Most people stand on the peddles when going over a bump so a seat switch would be bad.

    The brake handles have kill switches that feedback to the controller. I also want a master power cut off. Hence the 30 amp switch.
    I feel some casting coming on for the seat and the headlight housing unless I can source something more easily.
