Stolen Frog Bikes: UK Frame-Number Check (Free, Instant)
Last updated
Quick answer
Frog frame numbers are stamped on the underside of the bottom bracket. Frog is the UK's leading lightweight kids and junior brand, and because the bikes hold value strongly they are a frequent theft target, so run the number through Cyclesite's free lookup for an instant UK check against a stolen-bike registry and rider-filed theft reports.
Where Frog stamps the frame number
On the underside of the bottom bracket shell on the vast majority of Frog kids and junior bikes. Frog bikes hold their value unusually well second-hand, so the frame number and a receipt matter as much here as on an adult bike.
Frog on the UK used market
Frog dominates the premium lightweight kids market, with the numbered sizes (Frog 44, 48, 53 and so on) and the Road and Hybrid juniors changing hands quickly as children grow. Strong resale value makes them attractive to thieves, so always check the frame number and ask for proof of purchase before buying.
