woom OFF 5 - 24 inch Lightweight Kids Mountain Bike - Copper

Brand:Woom

Code:100018-0063-5001

The woom OFF 5 is designed for young riders who are ready to take their mountain biking adventures to the next level. Combining a lightweight chassis with premium off-road components, it offers the performance, control, and confidence needed to tackle challenging trails, woodland singletrack, gravel tracks, and family bikepacking adventures.

At the heart of the OFF 5 is a lightweight aluminium frame developed specifically for younger riders. Every aspect of the frame geometry has been carefully optimised to provide balanced handling, predictable steering, and excellent stability across varied terrain. The result is a bike that feels confident on descents, agile through corners, and efficient when climbing.

One of the standout features of the OFF 5 is its rigid carbon fork. Unlike heavier suspension forks often found on children's mountain bikes, the premium carbon fork keeps overall weight impressively low while helping to absorb trail vibrations and improve steering precision. This creates a more responsive ride that's easier for younger riders to control and enjoy.

The OFF 5 is equipped with a dependable SRAM 1x9 drivetrain, offering a wide range of gears without the complications of a front derailleur. The single-chainring setup keeps operation simple and intuitive, allowing riders to focus on the trail ahead while still benefiting from gearing that can handle steep climbs, fast descents, and everything in between.

Braking performance comes courtesy of Promax hydraulic disc brakes, delivering powerful and consistent stopping control in all weather conditions. Hydraulic braking requires less hand strength than traditional rim brakes, making it particularly beneficial for younger riders while providing excellent modulation and confidence on technical terrain.

The lightweight 24" wheels roll efficiently over rough surfaces while maintaining excellent traction and stability. Paired with grippy off-road tyres, they provide the confidence needed to tackle roots, loose gravel, woodland trails, and trail-centre loops with ease.

Every component has been chosen to support young riders as they progress their mountain biking skills. Child-specific contact points, an ergonomic saddle, and carefully proportioned handlebars ensure comfort and control, while the lightweight construction helps riders conserve energy and enjoy longer days in the saddle.

Whether it's exploring local trails, riding with family, or developing off-road skills, the OFF 5 delivers true mountain bike performance in a package designed specifically for younger riders.

Available in Black and Copper, the OFF 5 combines modern trail-bike aesthetics with premium engineering and adventure-ready capability.

Professional Opinion

The woom OFF 5 is one of the best examples of how a children's mountain bike should be designed. Rather than fitting heavy components simply to match adult bike specifications, woom has focused on creating a lightweight, high-performance package that genuinely benefits younger riders.

The rigid carbon fork is a particular highlight. While many competitors rely on basic suspension forks that add significant weight and often offer limited performance, the OFF 5 prioritises low weight and precise handling. This makes the bike easier to control, easier to climb with, and ultimately more enjoyable to ride on the types of terrain most young riders encounter.

The combination of the SRAM 1x9 drivetrain and Promax hydraulic disc brakes provides a level of performance usually found on much more expensive adult mountain bikes. Gear changes are simple and reliable, while braking remains powerful and consistent regardless of conditions.

For families who regularly ride trails, forestry tracks, gravel routes, and mixed terrain, the OFF 5 offers an exceptional blend of capability, reliability, and rider-focused design. It's a bike that encourages young cyclists to push their boundaries, develop their skills, and discover just how much fun mountain biking can be.
