bikerwannabe answers are:

1. No the Nova has no suspension. It competes with entry level folders in the market ( none of which have suspension ).
2. The full suspension is the most comfortable bike we sell. The front suspension is our commuter model. It swaps the rear suspension for a rear rack and rear fender ( please note a front fender is not required on most 20" folders ). Otherwise the two bikes are identical.
3. It depends what forks you swap ( steel vs aluminium ). However as a general rule, suspension adds about 2 lbs vs non suspension.

Thanks,
