There are lots of different ways to enjoy riding a bike, and it all starts here. Designed to create a more natural riding position for young riders, the Macaroni 20" open the doors to cycling.
BMX-inspired simplicity and durability mean the Macaroni is easy to ride and tough enough to keep on working. Carefully designed riding position allows young riders to feel balanced and confident. 2.4" wide tires smooth out bumps, and adjustable components help the bike grow with the rider.
