The Ridgeback Dimension 20 is a lightweight, premium bike designed for confident young riders aged 6 to 9 who want a smooth, easy-to-handle ride. With a strong aluminum frame and high-quality parts, the Dimension 20 helps kids explore new trails and master new skills with ease.
With 20-inch wheels and carefully tuned geometry, the Ridgeback Dimension 20 fits children approximately 120–135cm tall. It's the perfect step up for riders who are ready to take on longer rides and new challenges.
The Ridgeback Dimension 20 combines premium materials with thoughtful design to give kids a bike that's light, durable, and ready for fun adventures. It's built to inspire confidence and keep young riders excited to get outside and ride.
From the UK’s first MTB in 1983, through the Roxy, the introduction of the Urban series in 1998, the Genesis Day 03 flat bar road bike in 2001, the Dual Track 29er and the 25th anniversary R25, Ridgeback Bikes have been helping people get out and about for 40 years now.
For the modern Ridgeback range, E-Bikes are absolutely the present and the future. Cycling isn’t always about fun or fitness, sometimes (or even most of the time) it’s an incredibly powerful tool for just getting around without using a car. For that type of urban mobility, E-Bikes are the perfect solution which is why the Ridgeback range contains multiple different models at different price points so that you have a choice no matter where you are or where you need to get to.
But that’s not to say that Ridgeback has ignored the non-E-Bike, not at all. The range still has classic, powered bikes from £400 all the way up to £1,199.99, making sure there is a choice for every rider, no matter their budget. The other fundamental is to make bikes that complement lifestyle, not hinder it. That means every Ridgeback uses quality parts to make sure that they keep going for longer and wont let you down when you need them most.
The other fundamental part of Ridgeback bikes is the kids bikes. It starts with the Scoot and Scoot XL balance bikes that are designed to teach kids the fundamentals of bike riding without throwing pedalling into the mix and goes all the way up to the almost-adult-sized Dimension 26, Ridgeback’s kids bikes are proper bikes, not toys. That means they’re made to withstand the beating that kids can inflict and come back ready for more, they wont need a trip to the bike shop every 5mins because that’s doesn’t benefit anyone.
