Regen will only marginally extend your range (about 10%). And pedaling with the regen on will be almost as hard as trying to pedal while holding the brake down all the way.
For a low-power vehicle such as an eBike, regen offers very very little.

If you want to build an e-Bike I would recommend looking into hub motors. Golden motor offers some very nice kits in a variety of price points and performance levels.
