I have this bike extension to your existing bike. It fits to most of the regular bike or e bike. Just very lightly used sits in my basement most of the time. It’s great to ride with your kid/ small young adult for enjoyment, don’t need to worry about they fall or where they ride off to. It’s also easier for them to learn balancing on a bike. It is also foldable and fit in most of the car or trunk. It comes with all the parts and screws that comes with it
