Emie's Dad here, just wondering on behalf of Emie's friends parents what the go to 26" wheeled general use bike is for an 8/9 year old. Fully rigid preferred and some form of disc brakes would be nice. £3/400 new or less second hand.
He's outgrowing an Islabike so would prefer something similar, i.e. just a general cutting about bike with maybe some light off-road use, no drop bars.
