The same guy who posted the electric trike smoking the rear tire also converted a PK Ripper BMX bike to electric using 2 RC motors and some CNC work. Check out the setup in the first video. The CNC’d throttle is amazing to see. Check out the brute power display in the second and you will see why he needs the dual disk break setup. Especially the rear to keep the bike from looping out wheelies.

Check out this 40 Hp, 46 Volt electric powered trike roasting the back tire on pavement. It is a completely rediculous example of what electric drive is capable of.
Here’s how crazycrutch on YouTube describes it…
I have actually pulled 800 amps at 44 volts on this thing. So, I am up near 40hp for very small bursts. It will sustain 500 amps at 46 volts pretty much the whole time it is under load. I have over-amped the controllers, though. So, I am taking the gearing down from 60mph to 50mph top speed. That should give me 25% less load on the controllers. I am also going to program some throttle ramp into the system to eliminate the huge current spikes.
