Retrospec Koda 3, 20" Kids Bike, 2026 Blue Bolt

This Retrospec Koda 3, 20" is a great kids' bike and built for big-kid confidence on two wheels. The bike grows with the kids and fits 44" to 63" in height. Bonus sticker pack included.

Finally – a bike that can keep up with your adventurous kid. This 20” kids bike is the total package: it offers improved balance, effortless pedaling, dependable braking, and kid-sized ergonomics for the most comfortable, perfect fit. Its reach-adjustable V-brake is just like the hand brakes they’ll find on their first adult bike and offers stopping power that’ll keep them feeling safe and confident. Koda’s adjustable seat starts as low as 21.5” and adjusts alongside the handlebars to counter even the most drastic growth spurts. With Koda, they’re ready to rock and roll with the big kids. 

Grows With Them

This bike’s wide range of adjustable seat height, extending from just 21.5” up to 27.5”, can accommodate small riders and their growth spurts, so little cyclists can keep riding comfortably as their bike grows with them.

Optimized Pedaling

Pedaling on this bike is intuitive and efficient, with a gain ratio of 4.0. Every pedal stroke adds speed (“gain”) with just the right amount of energy (“ratio”) needed to propel them, resulting in easier starts & better balance.

Perfect Fit

A better fitting bike leads to faster learning, heightened confidence, & more fun. At 23.25 lbs, this bike is lightweight and easier for kids to maneuver. Its easy-mount frame & ergonomic saddle were tailor-made just for them.

Easy-Reach V-Brake

This bike features a highly responsive, easy-reach V-brake that teaches kids early how to use hand brakes like those found on adult bikes. Easily adjust the brake lever’s reach to fit smaller hands.

Wide, Cushioning Tires

Grooved tires reliably grip and can easily maneuver over different surfaces, making their ride smooth and stable no matter the terrain.
