Some kits are more reliable than others. If you have a chinese kit with a clutch and chain i wouldn't depend on it to get you to work and back. Riding it for fun on the weekends good idea. But the friction kits that do not have the clutch and chain and all the things to do wrong is a better nominee for riding to work. Just more reliable. I know cause i ride mine 50miles to work and back every day and besides flat tires haven't been left sitting for 2yrs now..you just gotta get one with a simple design that doesn't have all complications. The clutch puts out to much heat right next to the engine to be reliable for long distance..
