Some great looking kids bikes here.
Just a comment to make about the wheels. They really are worth spending the money on even if Crest rims seem a bit pricey as they make a massive difference to the weight of the bike and the way they ride.
Apart from the tyres and valves I lost virtually nothing on the wheels I built for my son so maybe worth spending the extra up front just on that item alone.
Everything else can be removed when you sell the bike and put on their new one.
I picked up Tom’s 26″ wheeled Whyte 403 today and will look to put on the XT running gear over the next week or so, all saved from the upgrades made on his Genesis.
