Cannondale Trail 24 children's bike Sonic Blue

Description

Cannondale Trail 24 kids’ bike Sonic Blue is a children’s MTB with 24" wheels designed for the step up from smaller sizes to faster riding on bike paths as well as on lighter trails. In terms of design, it sits in a more affordable performance category with a focus on low weight, easy handling, simple maintenance, and components sized for children’s anatomy. With an 8-speed drivetrain and a suspension fork, it targets riders who already know how to use shifting and want to develop their off-road skills.

Frame and geometry

The frame is made from SmartForm C3 Alloy and is set up for rim brakes, with mounting points for a rack/fenders, which broadens its use beyond pure MTB riding. On this model, Cannondale uses kid-adapted proportions (kid-correct reach and low standover) so getting on/off and keeping control of the bike is genuinely manageable for smaller riders. The bike is built around the 24" standard for a height of roughly 124–137 cm; the manufacturer does not provide specific reach/stack figures. The headset is FSA, 1-1/8", which matches widely available service parts.

Components

The drivetrain is configured as 1×8: microSHIFT shifting (trigger, 8 speeds) controls a Shimano Tourney TX rear derailleur, with a Shimano 11–32 (8s) cassette and a KMC Z8.1 chain. The Prowheel Pro-V30 cranks are 145 mm long with a 30T chainring, giving kids lower gearing for starts and climbs without the need for a front derailleur; the bottom bracket is cartridge, square taper. Braking is handled by Promax V-Brake linear-pull brakes with aluminum brake levers, making service straightforward and consumable compatibility high. The wheels use Cannondale lightweight alloy 24" rims (28 holes), hubs with sealed bearings (QR, rear 8s freehub), and Kenda Small Block 8 24×1.95" tires. The cockpit consists of 580 mm aluminum handlebars (25.4 mm) and a short 30 mm aluminum stem; contact points are handled by Cannondale Kids Comfort saddle and grips, and a kickstand is included.

Ride characteristics

The combination of an aluminum frame and 24" wheels delivers a direct response to pedaling and quick direction changes, which is key for learning how to manage body position and line choice off-road. The Suntour XCT-JR 24 suspension fork with 50 mm travel (coil) helps smooth out bumps on gravel and roots and improves front-wheel stability on rougher surfaces. The Small Block 8 tires in 1.95" width are a compromise between rolling resistance on hardpack and traction on dry trails. Rim V-brakes provide predictable engagement and low system weight, but their performance depends more on adjustment and rim condition than disc brakes.

Who it’s for

Cannondale Trail 24 is for kids around 124–137 cm who can already handle shifting and want to ride faster off the pavement: forest roads, hardpacked trails, and everyday commuting with the option to mount fenders and a rack. Compared with some competing 24" MTBs with disc brakes, it aims for simpler servicing and less complexity while retaining a suspension fork and 1×8 gearing.
