My daughter has been riding her two wheeler for close to a year, now. She has a healthy trepidation about riding on, or crossing, "big streets;" and several of her friends have those overpriced "towing wheel" cycles (see the second picture). The kind that can't be used for anything at all if they aren't attached to a grown-up's bike. Well, she wants a towing bike, too.
I'm not about to drop $300 when she has a perfectly usable bike already. Instead, I tried to build a towing rig that can attach to both of our bikes, and can also detach, leaving both bikes fully operational.
|DISCLAIMER This project did not work as intended. The trailing bike is not stable when towed, and falls to the side very easily, even without a rider. I have documented my work for completeness, but the device described here is not safe for use.|
I do intend to keep working on this, and try to find a way to reduce the swivel and sway to make it safe and rideable. If I succeed, I'll update this Instructable accordingly.
Update: It turns out that there's an instructable which discusses modifying a commercial product that does exactly what I'm trying to do here. I need to study that I'ble more, to see if it can help me with my issues here.
