Jett 16 Single Speed
Built to make riding fun
Kids move fast, and grow faster. The Specialized Jett 16 Single Speed is built around child-specific touchpoints — informed by Retül data gathered from a kids' research group — so young riders get a genuine fit instead of being stuck between too small and too big.
Best for: Young riders building confidence, bike-handling skills and a love of riding.

Key highlights
an adjustable handlebar and longer, extendable seatpost let you dial in the perfect fit as your child grows, extending the bike's usable life.
the 130mm Bridge saddle and narrower-diameter grips were sized from Retül research on young riders, not just shrunk-down adult parts.
V-brakes front and rear with reach-adjustable levers so smaller hands can brake confidently.
34T/16T gearing keeps the focus on riding and balance rather than shifting — ideal for a first pedal bike.
