and forgot to mention the first tentative attempt at riding! - Me going very slowly (and probably making it worse by wobbling) as grandad and stepdad ran along one each side, a pre journey lecture on the importance of HOLDING ON and how he has to concentrate and join in rather than the trailer which he just sits in singing away in a little dream world! - Needn't worry at all though, got on fine with it straight away, no wobbles (from him!) kept holding on, peddled, thought it was brilliant! It takes quite a bit of communication as you're going along (coming up to junctions and the need to stop peddling and then make sure he's concentrating with both hands on before pulling away and hasn't sat back and relaxed in the middle of a junction!
One thing I wouldn't agree with on the box though is the 'quick release' thing for unhitching childs bike, I find this far from quick release I'm afraid, and preferably a two man job - although it could just be me . . . .
