Frog 44 bike for sale. The Frog 44 is a 16 wheel Frog Bike – it replaced the Frog 48 in 2020 and is aimed at young riders aged 4-5 years old (with an average inside leg of 44cm) and weighs 6.39kg. Reflectors, mudguard and bell are all fitted. The bike is in extremely good condition. There were some light scuff marks to the brake levers (really common on a kids bike) but we’ve touched these up to the best of our ability to present the bike as close to new condition as possible for the benefit of the next rider. There is only very light wear and tear due to its light use. The bike has lived in a dry garage since new and has served our daughter extremely well whilst she transitioned from a balance bike to a pedal bike.
