Parent-Child Tandem - Non-Standard Connection

This instructable is relevant only if you have a FollowMe-Tandem (or Family-Cycling) parent-child bicycle connector and the two standard options for connecting the system to your bicycle don't work.

This weekend project has been documented in two Instructables. The twin Instructable can be found in the Non-Standard Child Bicycle Fit to Tandem with Adult Bike.

In Step 1 of this Instructable the FollowMe Parent-Child-Tandem is being introduced. Steps 2 and 3 explain how I managed to fix the FollowMe-Tandem to a towing bicycle in a non-standard manner (the standard ways didn't work). Finally, in Step 4 some words are being spent on the license of this Instructable.

Step 1: FollowMe Parent-Child-Tandem

The FollowMe parent-child tandem is a device for attaching a child's bicycle to an adult's bicycle. It allows to take a child with you on its own bike on busier roads in a safer way. Once you're in a more quiet area (parks, separate bicycle lanes, etc.) the bike can be decoupled easily and the child can continue on its own bike. It is a well-designed system by a Swiss manufacturer, which has two other innovative products available: a single-wheel kids carrier and single-wheel cargo carrier.

The next step elaborates on the standard and non-standard ways of connecting the tandem device to the towing bike.

interesting. how about an instructable on how to build one of the tandem aparatus thingies next? i'm interested to see how it works.

The basic principle of the connecting system is that the degrees of freedom of the following child bicycle are being limited. Of the three possible rotations two are allowed: tilting forward and backward (important for crossing a speed bump but also in curves, made possible through the front spindle connector) and turning left and right (important in curves, comparable to the principle of an articulated bus, made possible through the center hinge). The only rotation being suppressed is tilting side to side: the child bicycle will keep the same position as the towing bike (i.e. upright).

Additionally, if the towing bike assumes a prone position, the child bicycle will take that position as well. Perhaps some type of gimbal mechanism would be better. The current design allows for detaching the child bike so the child could ride on their own. So, if a child can already ride on their own and speed is part of the equation of remaining upright, the added speed of the parent bike should add to the upright stability of the child bike. Any tendency off vertical of either bike would not impart that tendency to the other bike.

I see the challenge of building one yourself, but also the risks involved: there are some safety issues to be addressed. I think that one of the strong points of the device shown here is that it is universal and capable of dealing with different types of bicycles (note however that the purpose of this Instructable has been to show that the standard solution for fixing the tandem to the towing bike does not always work, for which a solution has been documented). By releasing that constraint of universal application a DIY construction could be made slightly simpler. But the two free rotations need to be guaranteed in any design I think.

A great way to wait for a friend at a Bus or Train station, so that both can then go cycling, each on his own Bike.
