What makes our TWENTYFOUR SMALL so unique? We strive to offer the individually perfect solution for every child. As a dedicated manufacturer, we achieve this by choosing the exact right bike based on the inseam length. Recommendations based on age are much less accurate and can result in significantly shorter use. The focus is also on weight reduction, which is why we prefer a rigid fork over a heavy, poorly responsive suspension fork. There is no recommended, lightweight, and child-friendly suspension fork with V-brake available on the global market! To enhance damping off-road, lowering air pressure and using a voluminous tire (e.g., Schwalbe Rocket Ron 24 x 2.10) can provide good performance! It's not about "a" 24-inch bike but about the TWENTYFOUR SMALL or TWENTYFOUR LARGE! Following the "29er idea," the TWENTYFOUR SMALL frame allows children with an inseam length of 55 cm (measured with shoes!) to move up to the next wheel size. Our developed chain guard prevents the chain from falling, even on uneven terrain! The Shimano twist shifter is the consistently smoothest choice for enabling children to shift gears early. We firmly claim this today after having chosen other solutions over the past 10 years. Child-friendly crank arm lengths with narrow Q-factor prevent injuries to the musculoskeletal system. The Schwalbe Mow Joe 24 x 1.85 is the perfect all-round tire, exclusively made for Pyrobikes!! With its low profile in the center, the tire rolls easily on the road. Its volume provides sufficient protection against pinch flats when crossing curbs, while the stronger side tread gives the necessary grip off-road. Upgradable with: mudguards, luggage rack, kickstand, hub dynamo – Ask your dealer!
