Wahoo 20 Trail is a light and tough kids' bike that's ready to roll off-road. Its sturdy aluminium frame is easy to manoeuvre as they weave their way down the trail, but rugged enough to handle the tough stuff. A 9-speed 1x drivetrain gives them plenty of gears for pedalling up steep trails and disc brakes provide next-level stopping power to slow their roll or help them stop on a sixpence on the way back down. Perfect for riders between 114 and 132 cm tall.
You're ready to take your kiddo off-road and want a kids' bike that's up to the task. You want the added grip of big, knobby tyres, plenty of gears to keep them spinning up hills and the reliable stopping power of hydraulic disc brakes.
An Alpha Silver Aluminium frame with 20? wheels and wide 2.4? knobby tyres that bite into dirt and give plenty of traction. Tons of gears to pick from with a 9-speed 1x microSHIFT drivetrain and serious stopping power from hydraulic disc brakes.
Wahoo 20 Trail is a proper off-road ride in a pint-sized package. It's a kids' bike for little rippers who can't wait to cut loose and want a bike that's light, manoeuvrable and ruddy tough, too. Its hydraulic disc brakes give your kiddo a serious advantage while they progress on the trail.
- Wahoo's aluminium frame is light enough for easy handling and tough enough to roll through the rough stuff
- Hydraulic disc brakes give them the same serious stopping power you'll find on adult mountain bikes
- A 9-speed drivetrain gives your kiddo plenty of gears to shift through, but isn't too much to handle
- Wide and knobby 2.4? tyres provide heaps of traction for confidence on the trail
- Trek kids' bikes are designed and assembled by people who know bikes - and backed by a lifetime warranty
Lightweight carbon fork
A durable carbon fork cuts weight for easy manoeuvrability, absorbs bumps in the trail for happier rides on rough terrain and comes with a legit front mudguard that screams, 'real mountain bike'.
Dropper post compatibility
The Wahoo Trail can accommodate an internally-routed 31.6 mm dropper post for little rippers who want to get their saddle out of the way for extra rowdy descents.
Kid-friendly trigger shifters
Thumb-activated shifters make it easy to find the right gear and set young riders up for success with a kid-friendly version of the shifters you find on adult bikes.
Comfortable, confident geometry
An upright hybrid-style geometry mimics the feel of an adult bike and keeps kids confident and comfortable on the days when they want to ride until dinner time.
A better way to produce aluminium
Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.
Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
