DS1 currently rides an Islabike Cnoc 16 which he's had since he was 3 1/2. He's growing out of it so we are planning on getting him a new one for Christmas. The next Islabike up is Beinn 20 and costs £299 so we wanted to check what alternatives there are. Does anyone have any experience of Giant or any other makes for that age? I've just looked at the Giant website and the specifications for their 20" bikes don't include the weight which I find a bit worrying. Thanks in advance
