Kids can’t confidently ride if they’re not riding comfortably. With Riprock, fit comes first. We used data to reimagine everything from how they grip to how they sit to create a bike specifically and proportionally for kids. We did all this because comfort creates confidence. And more confidence always leads to more fearless riding.

2025 Specialized Riprock 20 Inch Kids Mountain Bike in Gloss Lilac

Season:2025

Brand:Specialized

Code:96524-8120

Freedom is the absence of fear. And fearlessly riding requires a bike that can handle your kid’s imagination. It’s why we designed Riprock to be a mountain bike inclusive of all the features needed for superior ripping—like modern geometry, Ground Control tires, hydraulic disc brakes, and internally routed cables. Finally, we threw in a wider-range drivetrain, making Riprock the perfect bike to inspire young riders to climb higher and tackle the downhills freely.

Kids can’t confidently ride if they’re not riding comfortably. With Riprock, fit comes first. We used data to reimagine everything from how they grip to how they sit to create a bike specifically and proportionally for kids. We did all this because comfort creates confidence. And more confidence always leads to more fearless riding.

Key Features:

  • Kids’-specific updates and features inspire confidence. A 130mm Bridge saddle, a narrower Q factor, and shorter cranks offer improved alignment between the hip, knee, and ankle to decrease the risk of injury and make your little one more comfy. Narrow grips and updated frame geometry offer improved handling, inspiring riders to ride more.
  • A lightweight package with an updated frame and wide-range drivetrain creates the perfect bike to tackle climbs easily.
  • Trail riding starts here. Inspired by Specialized’s heritage in mountain bike design, the Riprock offers modern MTB features such as a slack head tube angle, internally routed cables, hydraulic disc brakes, and Ground Control tires.

Click & Collect Orders

Please be aware Click & Collect orders may take some time to fulfil. We advise not to travel to your chosen store until you have been notified that your order is ready for collection.

Spread the cost of your new bike, helmet, safety equipment and accessories paying via instalments being taken directly from your wage. The payments for the Cycle To Work scheme are taken out of your gross wage and your Tax & NI contributions are then worked out based on your new lower gross wage which is how you save money on your new bike and equipment.

At the end of the time period specified with your Cycle To Work scheme you then have the option of buying your bike or to continuing to use it while you work for the company. If you decide to purchase the bike, the balance you owe will be based on a percentage of how much the bike was worth at the time you took out the Cycle To Work scheme.

We know how eager you'll be to jump on your new bike and hit the dirt or tarmac, so we give you everything you need to get you set up quickly. For full instructions on how you're bike will arrive and what you'll need to do, visit our How Our Bikes Are Built page
