Parents, this Büchel kids bike lock is the perfect way to teach your children about responsibility while keeping their bikes secure! The colorful, fun design makes locking up their bike something kids actually want to do, rather than a chore. The 4-digit combination lock means no keys to lose - your child can easily remember their special code, and you can reset it anytime if needed. With over 10,000 possible combinations, it provides solid security for typical situations where kids leave their bikes.
