Reid Tract Jr. 20 | 20" Kids' mountain bike
Built for young adventurers aged 7–9, the Reid Tract Jr. is a 20" kids' mountain bike designed to help young riders take on everything from neighbourhood rides to exciting off-road trails. With a lightweight alloy frame, front suspension and powerful disc brakes, it's built to give kids the confidence to explore further.
The lightweight 6061 alloy frame is designed with increased step-over clearance, making it easier for young riders to get on and off the bike. Aluminium kids' specific components help keep the bike comfortable and manageable for growing riders.
Front suspension helps absorb bumps and rougher surfaces, with 40mm of travel on the 20" wheel and 50mm on the 24" wheel. Alloy rims and wide 2.35" tyres provide grip and stability across a variety of surfaces, from park paths to local trails.
The Shimano 7-speed Tourney gearing gives young riders a useful range of gears for tackling different terrain, while powerful mechanical disc brakes provide reliable stopping and control when things get more adventurous.
Whether they're riding around the neighbourhood, exploring local parks or heading out on the trails with family, the Tract Jr. gives young riders the freedom to build confidence, develop their skills and enjoy the outdoors.
