The Coast Trail 20 is the bike that takes a young rider from wobbling about outside the house to riding to school and back. It's light, simple and built properly, with the sort of components that make riding feel easy at an age when a heavy, awkward bike puts kids off for good.
A Series 1 aluminium frame and matching alloy fork keep the weight low and the standover generous, so stopping and starting is never a drama. A smooth-shifting Shimano 7-speed drivetrain with an 11-34T freewheel gives enough range for hills and headwinds, and the Microshift short-reach shifter and kid-specific alloy brake levers are sized so small hands can actually work them.
Marin x Vee Tire Co. Speedster 2.0" tyres roll quickly on tarmac but have enough tread for gravel paths and the park, which covers just about everything a rider this age wants to do. It's a proper little bike rather than a toy.
