Re: First motorized bike for city use
Most people have no problem pedal starting the motor on a single speed.
Your motor bike choices sound good to me.
The Micargi Falcon has little space in the frame for a motor, but the Rover should have plenty.
A front disk brake is a good idea for emergency stops in the "Cold Kentucky Rain".
You will need a disk brake compatible front fork and hub, unless you do some fab work or buy an adaptor kit from a vendor like Venice Motors.
