Mounting adult bike brakes onto a children's bike isn't possible. That’s why the Numove 240 Disc is equipped with 140 mm rotors and ergonomically sized levers on the hydraulic Tektro disc brakes. These can be extensively adjusted to match the strength and skill level of young, lighter riders. Additionally, it features Performance 22 Light wheels from Newmen, fitted with Schwalbe Smart Sam tires. The smooth 8-speed gear system provides the right gear for every situation, and with an adjustable stem integrated, the fit can be customized, allowing the bike to grow somewhat with the kids. In summary, it’s the ideal complete bicycle package for adventurous youngsters!
