Actually, our adult training stabilizers always fit on your bike. So you don’t have to worry about that. It is always possible to order the Swinging Wheels separately from us. However, we always recommend that you have our support wheels purchased and mounted by a bicycle specialist. This is because mounting the springy training stabilizers cannot be compared with, for example, mounting training stabilizers on a child’s bicycle. The training stabilizers can be mounted quickly and professionally by your bicycle specialist. You will also receive an explanation of how to use it. With your current bicycle you will immediately receive an electric tricycle when you have the Swinging Wheels mounted on your electric bicycle.
