I helped out with my daughters year 3 bike ride. A ~2 mile pootle, including some mildly technical rooty single track and a couple of tunnels under the railway bridge and by the river. There was the usual selection of bikes from bling Islabikes and Specialiseds, BMXs, to supermarket specials. Everyone had a good time in the rain apart from one lad on a “stunt bike”. His supermarket BSO had twitchy steering and wouldn’t go in a straight line, had lousy brakes, and plastic tyres. The poor lad fell a couple of times (once into nettles) and nearly ended up in the river. Sorry for the ramble, but…nice bikes are nice (we know that), heavy framed bikes are OK if the steering and brakes work, and beware of anything with “stunt” written on it.
