HOY Bonaly 20 Inch Kids Bike. For keen junior Hoys, the Bonaly 20 is a simple go-anywhere ride that puts quality and easy riding first. The spec includes proper bearings, simple Shimano 6-speed gears with a double chain-guard for fewer (if any?) dropped chains and light integrated headsets for a neat, refined look. Making a great children’s bike at Hoy starts with shorter cranks than most children’s bikes are commonly specified with. This and the rigid forks used means we can drop the frame / bottom bracket as low as possible to make the frame as stable and manageable as possible for small riders. The Bonaly is named after the area at the foothills of the Pentlands where Sir Chris ventured off-road for the first time, so the Bonaly 20 uses semi-treaded Kenda Small Block 8 tyres with a large volume to make those first excursions in safe places like a park or flat woodland a little easier.
