Integrated handle
Hidden handle under the saddle helps you guide your child while they learn to ride.
Suspension fork
Front suspension absorbs the bumps of the road, path and trail, and looks cool while doing it.
A better way to produce aluminium
Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike we make, this one included, had made the switch, driving a major drop in our footprint.
Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
