Ridgeback MX20 Kids Bike in Turbo Teal
The Ridgeback MX20 is a lightweight kids mountain bike for riders aged 6 to 9, roughly 120–135cm tall. Where the Ridgeback Dimension range is built around road and path riding, the MX20 is designed for children who want to go off-road, cut through parks, and treat every muddy track as an invitation.
Built tougher
The 6061 heat-treated aluminium frame is light enough for a child to manage but durable enough to handle drops, scrapes, and the general lack of care that kids this age give their bikes. Multi-surface tyres on 20 inch wheels grip well on grass, dirt, and gravel without dragging on tarmac, so the ride to school and the ride through the woods both work on the same rubber.
Gears that make sense
The 6-speed Shimano drivetrain with Revoshift gives young riders a twist-grip gear change that's simple to use without looking down. Six gears is the right amount at this age, enough range for hills and headwinds without overcomplicating things. For a kids bike with gears in the UK, the Shimano setup is reliable and doesn't need constant tweaking.
Sized for children
Ridgeback have kept the same child-specific approach across the MX range:
- Easy-pedal cranks proportional to a child's leg length, positioned closer to the centre of the bike for natural pedalling
- Narrower handlebars and smaller-diameter grips that fit small hands properly
- Adjustable brake levers sized so children can reach them safely
- A lowered frame for easier mounting and dismounting
- A steering limiter to prevent over-steering while coordination develops
These aren't afterthoughts. A child who can reach the brakes and change gear comfortably rides with more confidence and stops more safely.

Who is it for?
The MX20 suits children who want more from their bike than path riding. If your 7 year old is drawn to dirt tracks, park trails, and rougher ground, this is a better fit than a road-focused Dimension. It's a durable kids bike that handles being thrown around without falling apart, and the Turbo Teal colour looks good even when it's covered in mud.
If your child mostly rides on pavements and cycle paths, the Dimension 20 may be a better match. The MX20 is for the ones who'd rather ride through the puddle than around it!
