YOMO 20 has a maximum permissible total weight of 65 kg. This includes the bike, rider, and any luggage.

Featherlight Build, Endless Fun

The YOMO 20, weighing just 7.6 kg, proudly stands out as one of the market's lightest 20" wheel children's bikes. Designed with a Triple Butted lightweight alloy frame, it offers exceptional ease of handling. We design all of our bikes to give children a boost. Whether they're just learning to ride or are already confident little cyclists, YOMO bikes help them tackle hills with ease and ride longer distances, all whilst always maintaining a big smile! The child-specific components ensure not only that the bike remains as lightweight as possible but also that it's comfortable and easy to use. As children effortlessly lift and manoeuvre their YOMO bike, their cycling confidence grows, leading to more adventures and a healthier lifestyle!


YOMO's child-specific geometry ensures a safe and comfortable riding experience. Unlike traditional bikes, YOMO positions the rider's centre of gravity slightly further forward, ensuring intuitive balancing and stability. This helps young cyclists quickly master their bike and get on with enjoying endless adventures.

Designed with Young Riders in Mind

The YOMO 20 features junior-specific, reach-adjust brake levers, fine-tuned for young riders' hands, ensuring effortless yet safe braking. This is further complemented by slim ergonomic handlebar grips for ultimate control, precision mini V-brakes, and a handlebar made to the perfect width for young riders. Alongside its ergonomic saddle and optimal crank length, every ride becomes a blast. No more stretching due to poorly designed components, or the upset from tired legs pushing a heavy bike uphill - all thanks to these premium junior-specific components and YOMO's frame geometry

Shifting Magic: Gear Up, Speed Up!

With Shimano's 7-Speed Rapidfire Plus gear shifters, children can glide through the gears like never before. Its unique ability to downshift three gears at once, paired with an optical gear display on the handlebars, ensures an unbeatable riding experience with ultra-light shifting at their fingertips. Precise and easy-to-use, this gear-shifting not only helps children learn to use gears quicker but also allows them to ride further and on more varied terrain. Shimano's 7-Speed freewheel (11-28T) quietly does its job on the back wheel and is perfectly complemented by a 32-tooth chain ring up front

Optimal Cranks, Narrow Q-Factor

Unlike many children's bikes, which adopt the same Q-factor as adult models, leading to a wider, less ergonomic leg stance, the YOMO 20 stands out. Our bikes are equipped with optimal cranks featuring a narrow Q-factor, ensuring a more comfortable and ergonomic position that's gentle on young hips and knees


With quick-release skewers, removing and installing your bike's wheels becomes stress-free. Whether you're removing a wheel to fit all the family's bikes in the car, or doing a roadside puncture repair, this tool-free solution makes it a doddle


Jump on board our top-quality saddle from the globally renowned brand, Selle Royal. Specifically designed for young riders, its ergonomic shape promises unmatched comfort. And with advanced water-resistant vacuum technology, parents can be assured of its lasting quality


From playful outings to muddy adventures, our hubs are always up for the challenge. Our sealed bearing hubs guarantee a smoother ride and longer-lasting performance, ensuring the bearings remain free-spinning and clean, even in the mud.


YOMO 20, fitted with stainless steel spokes and rust-free wheel nuts, promises endless fun paired with unmatched durability. With less maintenance and no worries about corroded parts, this bike stays looking great for longer, making it a perfect investment that lasts for countless fun-filled journeys.
