Re: New to motorized bicycling and I have some questions.
Use the search bar at the top of the page, and you'll find all kinds of information about alternate motors people have used besides kit motors.
Use of the bike's own sprockets and chain will depend on the motor you go with, and if it's drive goes the same direction as you want to go once the motor is mounted.
Any day that starts with a good ride is already a better day, and a bad day riding still beats a good day working.
