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