Thanks, Steve, this is the kind of information I need.
I suppose I should just bite the bullet and go for used wheelchair motors
instead
of scooter motors? Other than cost, is there any advantage using a scooter
motor
instead of a wheelchair motor?

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.
