What makes our TWENTYFOUR LARGE so unique? We strive to offer the individually perfect solution for every child. As a dedicated manufacturer, we achieve this by selecting the exact fitting bike based on the inseam length. Recommendations based on age are much less precise and can result in a significantly shorter period of use. It's not just the 24-inch bike that is in demand, but the TWENTYFOUR SMALL or TWENTYFOUR LARGE! Following the "29er idea," the TWENTYFOUR LARGE frame allows children with an inseam length of 59 cm (measured with shoes!) to transition to the next wheel size. Our developed chain guard prevents the chain from falling, even on rough terrains! The Shimano twist grip and 8-speed derailleur are the consistently smoothest choice to enable children to shift gears early. We state this firmly today, after having chosen other solutions over the past 10 years. Kid-friendly crank lengths with a narrow Q-factor prevent damage to the musculoskeletal system. The Schwalbe Mow Joe 24 x 1.85 is the perfect all-round tire, exclusively made for Pyrobikes! Thanks to the low profile in the center, the tire rolls smoothly on the road. Its volume provides sufficient security against punctures when crossing curbs, and the stronger side profile gives the necessary grip off-road. Upgradable: fenders, luggage rack, stand, hub dynamo – ask your dealer!
