I've already tried the bike with a simple on/off switch at 60v (no controller. it was awesome torque,horrible range, very jerky and scary).

For the car, I'm going to use an off the shelf hall effect sensor. It's like $16 I think. It can read up to 600 amps.
Possible Choice for Hall Effect Current Sensor

That sounds like an awesome project you are doing! I hope you keep me updated. I like the idea of having modules that can attach to increase the max amps. That sounds very interesting!
