Under $250 brushless Ebike

There are plenty of hub motors out there but I still wanted to see if these low cost, low weight, high quality/high power components could compete with what is out there.

$60 brushless outrunner motor (400W-800W)
$50 speed control (60A 12V-16V)
$18 throttle
$99 beach cruiser (Aluminum frame, steel forks)
$Lithium polymer power! Only 5 ounces per 2AH or 6AH per pound at 12V!!!

Note with Lipolys you can run a motor at 12V and amps above 50A no problem!!!
Chainging together lipolys in series to get voltage over does the amount of amps available and is why packs sound so expensive that way. Keep it at 12V and in paralell and the money problems are solved with hundreds of amps available in power.

Weight for the setup including battery, speed control and motor is just a few pounds!
Adding 2 more horsepower (2 more motors) would only add 1 pound!

The bike pushed me around find without needing power from me.

This is just a quick test setup and not even meant for a bicycle necessarily.
The motor should be mounted to take strain off the shaft to prevent damage to the motor.
