    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.
