Kids 26 Inch Hybrid Aluminium Bike Riverside 900 – Children 9-12 Years Old BTWIN. Want a light bike? This hybrid bike is perfect for kids aged 9-12 (135 to 150 cm tall) who want to ride in the city and on trails. With its aluminium parts, this hybrid bike weighs just 10.5 kg! With its 8 speeds and hybrid tyres with knobs, you can enjoy rides on both roads and trails. A lightweight bike: aluminium frame and fork. We had to choose aluminium for this bike’s frame and fork because we wanted to make it as light as possible. Aluminium is particularly hardy: the frame and fork won’t rust, even in tough environments damp, salty, etc. If you’re not satisfied with an item you’ve bought online, you have 30 days to change your mind as long as the item is unused and in its original packaging.
