The Thrax is built for a teenager or a smaller adult, and the 24-inch wheels make that clear before you even check the spec sheet. The 21-speed drivetrain and disc brakes are the same core equipment you want on a bigger bike, and the front suspension fork softens curb drops and rooty paths without making the bike overly complicated. For a first mountain bike, that is a sensible combination.
We think the Thrax is the pick when fit matters more than wheel size. The 24-inch platform is easier to handle for smaller riders, and the 21-speed gearing gives them room to grow into hillier rides. The one-year manufacturer warranty is a real plus at this price, and the disc brakes are a better choice than the V-brakes on some cheap bikes. We also appreciate the adjustable seat and handlebars, which make it easier to dial in the fit.
What we like most is that the Thrax does not feel like a stripped-down toy. The charcoal gray finish looks more expensive than the bike's place in this group, and the trigger shifters are easier to use than twist grips for most riders. For a teen or a smaller adult, this is the one we recommend first.
Bottom line: Our pick for a teenager or smaller adult, the Thrax 24 pairs 21 speeds and disc brakes with a fit that full-size bikes can't match.
