    Jett 20

    Delivery Icon

    We deliver! Just say when and how.

    Kids move fast, and grow faster. At times, it can seem like there’s a small window for the perfect bike fit. The right bike for a young rider is a delicate balance between too small, too big, and a short-lived just right. If we’re going to inspire the next generation of riders, we need to keep kids comfortably riding longer.

    The Jett is designed so that you’ll never fear the growth spurts. We did our homework to understand how kids grow—spoiler alert, kids’ arms and legs grow more rapidly than their torso. We took to the books and designed a bike with child-specific touch points that withstand the development of young riders. The Jett is uniquely adjustable, perfectly proportional, and child-liftable—they’ll always be set to Jett.

    The Jett Multispeed features an adjustable handlebar that allows kids to fine tune reach as their arms grow. The 2-hole position cranks combined with longer seat tubes give plenty of flexibility to dial-in the optimal pedaling position. And whats more, we designed the frame and reviewed every component to make the Jett one of the lightest bikes on the market. You’re going to have to beg them to get off this bike.

    I bought this bike for

    I bought this bike for my 8 year old son as his first proper bike now he’s grown and competent at riding. Really impressed and if you can afford it I would strongly recommend this bike. It has a great set up and it’s relatively lightweight. I looked around local bike shops and Halfords and I’m certain I made the right decision getting this bike.

    A great first bike for

    A great first bike for my son. Only gripes are that the gears are hard for him to use as they aren’t ergonomically suited to smaller hands and the wheels and seatpost would benefit from being quick release.
