Hi wondering if anyone has used a pulley based cvt for pedaling or
a motor drive ive seen some of the pulleys and looks like they could be
used in a bike application fairly easy
 
They've been used with IC systems. Both the larger, 'comet' style CVTs, and the smaller, pocket bike CVTs. Take a look in the CVT forum

You should be able to connect an electric motor to one without too much problem - you just need to match the motor RPM to the CVT 'shift points.'

One point to keep in mind is that the pocket bike CVTs start off in the 90-92 percent efficiency range, and as the belt wears, the efficiency slowly drops, down to about 85%. They do have a step-down gearbox on the output, which can make getting the rear wheel RPM correct, a little easier.
