Frog 48 - 16 Inch-Wheel Kids' Bike Frog is a British company specializing in better-quality, lighter weight kids' bikes. Key Features Lightweight aluminium alloy frame (9.5 inch seat tube) and fork. Lightweight aluminium wheels. No gears for single speed simplicity. The alloy cranks are a child-friendly short (102mm) length with 32t chainring. The sealed bottom bracket ensures these cranks spin freely. The 440mm alloy handlebar is fitted with narrow grips for smaller hands. The bars are fitted to a short 35mm alloy stem to keep them within easy reach. Tektro alloy V-brakes with alloy levers are such excellent stoppers, they are a common sight on good quality £300-£400 adult bikes. Minimum recommended inside leg measurement to the floor: 48cm. Minimum recommended child height: 110cm. Approximate age range: from 4-5 to 7-8 year old. Manufacturer's published weight: 6.75kg. Frog bikes, like better-quality adult bikes, are built with aluminium frames and (mostly) aluminium parts to keep the weight to a minimum. That way your child(ren) will experience maximum joy riding one of these bikes. An example of their original approach, rather than numbering their kids' bikes by wheel size, Frog size their bikes by inside leg measurement. Hence the Frog 48 is recommended for children with a minimum inside leg measurement of 48cm (19 inches). This corresponds with other manufacturers' 16 inch wheel kids' bikes, so the Frog 48 would make a great present for children from 4 year olds. It comes with a long aluminium seatpost with a quick release seat binder to make it easy to adjust the saddle as the child grows all the way up to 7 or 8 years old. Faster Wheels Another original detail is that the Frog 48 comes with lightweight alloy wheels fitted with good quality Kenda 16 x 1.5 inch hybrid tyres which will be easier rolling than the 16 x 2 inch knobbly mountain bike tyres you'll find on most of their competitors' bikes. Skinnier tyres make a Frog bike easier to accelerate and hence more fun to ride much of the time. Choice of Colours Technical attributes aside, this is no ugly frog. Frog bikes look good, so your child should be really proud to own one. To help ensure they delight, Frog bikes are available in a choice of colours. Frog Video Frog's passion for making better bikes for kids shines through in this video. 'Frog Bicycles We are a small British company dedicated to making cycling fun for children. We believe that the lighter the bike, the easier it is for children to learn to ride, and to enjoy it more as they progress. Many children's bikes on the market weigh nearly as much as the child! So we set about re-designing the kids' bike, sourcing a light but strong aluminium frame, and hand-picking components that offer a high performance without compromising the weight. The founders, Jerry and Shelley, are a couple who have 2 small children of their own – both keen cyclists. So they know something about what motivates children to get on their bikes! Since the first prototype arrived, the bikes have always been robustly tested by the children and all their friends.' Frog. Shop All Frog Bikes > Shop All Kids Bikes > Frog Bikes Size Guide >
