Little Wheels, Big Fun

The On-One Piccolino kids 'Fat Bike' is the gift every kid wants, big and small!

Packed with the same quality design features and craftsmanship as our full-sized mountain bikes, the Piccolino is a 'Honey I Shrunk The Bike' kiddie-sized version. The Piccolino frame is made using oversized 6061-T6 alloy tubing and we've squeezed in a burly 20" wheelset ready to tackle anything. With seriously grippy 2.5" Maxxis tyres, the Piccolino turns any family weekend bike ride into an adventure the kids will love.

Because the Piccolino is so capable, you and the kids can spend more time riding off-road, away from the hazards of the road and moving vehicles. Versatile geometry ensures the Piccolino rides great and fits a wide range of rider heights, too - ideally suited to kids between 5 and 10 years old (depending on size). Powerful disc brakes and seven Shimano gears mean the Piccolino will grow with your child as their riding skills develop. The Piccolino is the perfect gift to give your kids two-wheeled freedom and a life of adventure!
