Falcon Jetstream 20" Kids Boys Mountain Bike - Grey

Designed for junior riders, the Falcon Jetstream 20" Kids Boys Mountain Bike offers a considered riding position for children aged 6–9 years, helping them feel comfortable and in control as they build confidence. A hi-tensile steel MTB frame is paired with a lightweight rigid fork for a stable ride, with a curved lower section intended to reduce vibrations from the pavement.

Progression comes naturally thanks to 6-speed gearing powered by a Shimano rear derailleur and Revoshift shifter, allowing smooth changes without letting go of the handlebars. Practical details support everyday riding too, including a double-sided chainwheel guard to help protect fingers and clothing, plus MTB-style pedals for reassuring grip. Front and rear V-brakes are matched with reach-adjustable brake levers designed to accommodate smaller hands, while the longer 250mm seat post, adjustable saddle position and quill stem help the bike adapt as they grow. Strong yet lightweight alloy rims and all-surface tyres are built for riding across a variety of terrain.
