I've had a search on this subject but can't find anything specific. There's a three year age gap between my kids and I'm having problems integrating my social time with one and the other. They can both cycle, but the youngest (5) isn't ready for the longer rides and can't do roads yet. He gets left out quite a lot and the obvious solution would seem to be a Trailer Bike so we can do this as a group. The majority of the rides are off main roads and on cycle tracks and the like at the moment. Is a Trailer Bike the answer? If so, which one?
