Q- Why should I convert my bicycle?
A- There are many good reasons, but only enough space for a few. You get tremendous savings on your gasoline bill, plus this ride is an exhilarative experience you can't get enough of and it makes a great backup transport.
Q- What kind of bicycle can be used with our engine kits?
A- Most any 26" V-frame bicycle will work with no modifications. You want to make sure there's enough clearance for the motor to fit inside the frame (Bikes with rear suspension in the v-frame will not work).
Q- Is it legal to operate a motorized bicycle in my state?
A- Motorized bicycles are considered pedal assist bicycles and are legal to operate in most states without a driver's license, registration, or insurance. For more information contact your local authorities.
Q- How do I know if this is a good deal?
A- Because you know the cost and disadvantages of other vehicles; example-A motorcycle can go faster, but you can't peddle and you need license and registration. A car can go faster and take passengers, but it cost much more in fuel cost, licensing, insurance and maintenance; you also can't take it inside your home. These are just some of the advantages of owning a sleek, dependable, clean, lean and mean machine!
