They’re growing up, so they need a more grown-up bike. Dart was designed to help kickstart their transition from kids’ bike to adult bike – it features the same 7-speed drivetrain & shifters found on some of our adult bikes, and a kid-sized V-brake packs the same stopping power as the grown-up hand brakes they’ll be learning how to use. They’ll get familiar with switching gears while being able to expand their bike route to include more varied terrain, and the bike’s ergonomic design was tailor-made to support the perfect riding position for smaller cyclists (even while they continue growing!) and have them feeling comfortable and confident on two wheels as they maneuver the neighborhood streets with ease.

Taking children’s unique proportions into account, this bike is tailor-made just for them – its ergonomic design with adjustable height supports a comfortable riding position as they keep growing, its size and weight allow even smaller cyclists to handle the bike with ease, and cushy, shock-absorbing tires will keep the cruising smooth ride after ride.
