The PUMA hub motor is light and very well made, removal of the motor front plate exposes the motor windings which are fixed in to the inside stem of the motor, the rotor and magnets spin in the  opposite direction, on the outside of the rotor the gear is fixed, this in turn drives the hub of the motor around the axle.

The gear reduction is 5:1. The phase and hall wiring exits through an 8mm hole inside the axle, with approx 150mm of cable extending for both the phase and hall wiring.

In motion the PUMA motor freewheels very nicely with no drag, under low speed the motor has finite control, it is possible to move at very slow speeds smoothly all the way up to full speed with no Jumps to full speed or any notchy jumps in speed.

The low down acceleration of the PUMA is very impressive, it has very good torque indeed and keeps pulling right up to the top speed where it settles nicely. The motor is not noisy however it is more noisy than a none  geared hub motor and it is marginally noisier than a Currie USPD, this isn't really a problem and in traffic it is not noticeable.

The hill climbing capability of the PUMA is also very impressive indeed, steep grades can be attacked with relative ease in fact in a 20 inch wheel it will spin the front tyre easily going up ramps in car parks.

An important note is that this motor must be fitted with a torque arm and must not be fitted to aluminium suspension forks, even with a torque arm this motor could possibly damage or even snap the fork drop outs, steel forks are recommended.

The PUMA its relatively light has little free wheel resistance and has great top speed, its easy to fit, its very adaptable for different battery configurations and uses a tested and known motor controller.
