Not all bikes are created equal
Every last part of the HERO 20” has been carefully considered to optimise weight, quality, comfort, safety and style. Weighing just 7.9kg, equipped with a silent, smooth belt drive system, ultra-reliable Shimano 3 speed hub and available with a free lifetime warranty for the frame and forks – the HERO 20” has been built to last.

Less weight, more fun
A lighter bike is easier to learn on, easier to handle and more enjoyable to ride meaning your child will be happy to ride the HERO for longer than a heavier bike. At 7.9kg the HERO is among the very lightest 20” kids bike on the market.

No more chains
Quieter, smoother and longer lasting the HERO comes with a Gates belt drive system which is maintenance-free: no oil, no grease, no rust (ever!) and safer for inquisitive fingers too.

Lifetime Warranty
HERO’s are designed to last a lifetime which is why we offer a free lifetime warranty on the frame and forks to the original owner for as long as they own the bike. Visit our 'Warranty Information' page for more details.

Perfectly proportioned.
Comfort is key, which is why the geometry of the HERO 20” has been designed to put the rider in a more upright position, making it quicker and easier to learn and optimising the riding experience.

Shimano Nexus-3 Internal Gear Hub.
Shimano’s internal gear hub is virtually indestructible, the grip shift is easy for children to twist and can be done even when they’re not pedalling (so no more getting caught at the bottom of a hill in a high gear!). Children find it easy to use the high, medium and low gears.

Efficient cycling.
Fitted with longer cranks that enable gearing with a better Gain Ratio, the HERO 20” requires fewer rotations to travel the same distance when compared to a shorter crank. This makes for a more efficient ride on the flats.

Brake levers made for small hands.
Small, easy to reach, adjustable brake levers, more manageable narrow handlebars and contoured grips means better control and improved confidence.



Carefully prepared by us.
Every one of our bikes is inspected by our UK based trained mechanics who will assemble and tune your bike before it's sent to you. When it arrives, some simple assembly will be required.

Frequently Asked Questions
Do mudguards and a kickstand come with the bike?
You can add these as additional extras when you buy the bike. If purchased, the kickstand will come fitted to your bike already. The front and rear mudguards will come loose in the box. To fit them you will need to follow our step-by-step instructions which can be found by following the link found in the 'Mudguards Information' link at the top of the page.
Can stabilisers be fitted to HERO?
Universal stabilisers can be fitted to HERO, but it is not what we recommend or stock. If your little one is 30 to 48cm then we would recommend the AIRO balance bike instead of stabilisers.
What size HERO should I get?
HERO pedal bike sizes are based on inside leg measurements. The 14” pedal bike is designed for an inside leg of 34-44cm (approximate age 2.5-4.5 years old). The 16” pedal bike is designed for an inside leg of 40.5-50.5cm (approximate 3.5-6 years old). The 20" pedal bike is designed for an inside leg of 48-56cm (approximate 6-9 years old). The 24” pedal bike is designed for an inside leg of 57-67cm (approximate 8-10 years old).
What is the difference between a belt drive and a chain drive?
Belts are set at a higher tension than a chain and so feels different. Initial 'stiffness' wears off very quickly. We prefer belt drives as they are maintenance and oil free, and safer for inquisitive fingers!
