I trashed my 24v experimental bike today. I decided just to keep one bike. The bike I kept has a controller that will work at 24 or 36 volts. 24v with a controller is crap. If I build another bike ever it will be 24v no controller. I caught a ton of grief on the forum for advocating that kind of bike but it is the way to go for me anyway. Should the controller on the bike I have now go, I will convert it to 24 volts no controller in a minute.

Meanwhile I have a much faster bike in the 36 volts so I will ride and enjoy it knowing that it is best only for the speed.

I may try again to get the direct drive with skateboard wheel working. I just need a better connection to the motor.
