My sons just outgrown a Carrera Blast 20" ... tAodl0cAdA

and looking to replace it with another flat bar general use type bike. Can anyone recomend a decent 24" for him - can't afford Isla etc as top budget is £200? Nothing doing in 2nd hand that I can see (on here or ebay) and don't really want just get next size up in Carrera as that seems a bit boring. The Blast is Al frame and it makes a big diff to weight so don't want steel as steel kids bikes seem to all weigh a ton. Any advice experience apprecaited
