Some thoughts on scooter motors.
Scooter motors come in two varieties, brushed and brushless. Make sure you get a
brushed motor. Brushless motors require a special controller and may not be
reversible. Other things to keep in mind,
- Scooter motors are timed to run faster in one direction (like EV Warrior motors,
usually CW).
- Scooter motors are environmentally sealed (no air holes) and are prone to heat
damage when stressed.
- They are generally 24 volts though motors for Zappy scooters are 12 volt.
- The cheap ones are rated around 150 to 250 watts (EV Warriors are 900 watt, 1.5hp
at 24volt).
- A plus is they have a belt or chain sprocket pre-installed on an 8mm shaft.
A wealth of info on scooter motors and scooters in general can be found at the Yahoo
Zappy group and the Voltage Forum,

Here you'll find info on ventilating and "hopping up" scooter motors.
