between MTB Trail and Cyclepath

Grand Canyon Young Hero 27,5 Zoll Review

Suspension fork, disc brakes, and a decent drivetrain. The Canyon Grand Canyon Young Hero 27.5 delivers what one would consider a proper mountain bike for kids. And that for a price of 699 €. Is there a catch?

The youth hardtail from Canyon is available for €699. Can you really go mountain biking with it?

For many kids and teenagers, mountain biking is an ideal balance to a life with digital media. Instead of sitting in front of screens for hours, riding on trails offers exercise, a nature experience, and a genuine sense of adventure. The mix of physical challenge, thrill, and outdoor action especially appeals to young people, while also boosting their self-confidence and fitness.

However, such enthusiasm has its price—literally. Looking around the MTB scene quickly reveals that the gear can be quite expensive. Especially for ambitious young riders, you often see bikes that cost more than €1,500. Canyon aims to tackle this with the Grand Canyon Young Hero by offering their Grand Canyon Young Hero 27.5-inch for €699. But does this bike offer more than just leisurely laps in the park—is it a real sports machine or more of a practical compromise?

When is a 27.5-inch mountain bike suitable?

The old rule of thumb (“Feet must touch the ground when sitting on the saddle”) loses significance as kids get older. A seven or eight-year-old child can handle slightly tilting the bike while standing to reach the ground with their foot.

Starting from a wheel size of 24 inches, it’s more important that the saddle can be adjusted so kids can pedal ergonomically perfectly.

The wheel size of 27.5 inches is roughly equivalent to 26-inch wheels in terms of bike size. Our experiences on kids-bike-test.com show that a bike with 27.5-inch wheels can be considered for a height of about 135 cm. Before that, it’s not very sensible. Canyon offers the Grand Canyon Young Hero 27.5 in two frame sizes. Our tester, just under 140 cm tall, used the 2XS version. The larger XS version has the same seat tube, but the main frame is significantly bigger.

Bike Setup: Work Comes Before Fun

Especially for kids, it’s crucial to pay attention not only to the wheel and frame size but also to ensure the components are ergonomically suited to the children’s body.

The Canyon Grand Canyon comes stock with a sensible crank length of 155 mm and a short 45 mm stem. We slammed the stem for our 135 cm tall test rider. This allows kids to apply enough pressure on the front wheel.

However, we trimmed the 350 mm long seat post a bit so that the saddle can be fully lowered into the frame. In the factory configuration, this wasn’t possible. This not only allows for the ideal seating position but also lets you drop the saddle when hitting the trails.

Handlebar Width Kids
As parents, you often hesitate to use the hacksaw on things like the handlebars. However, if you notice that they are a bit too wide for your child, it's worth the effort.
Kids' Bike Size
Kids grow up fast. What seems too big today might fit perfectly in just a few months. Regularly checking the saddle height is especially important for kids' bikes. If the saddle is too low, kids can't pedal properly.

Air suspension fork is key

Unlike the smaller Grand Canyon with 24-inch wheels, the larger 27.5-inch model actually features an air suspension fork.

The fork can be properly adjusted to the low body weight of children. The appropriate pump is included in the delivery. This option significantly enhances the bike’s value. Inexpensive coil spring forks not only have poorer responsiveness, they also typically offer less travel. With 120 mm, the Young Hero is well-equipped for technical trails.

With 120 mm travel, the fork on the Canyon Grand Canyon is generously equipped for real mountain bike trails. Other youth bikes often only have 80 mm of travel.

Lockout
On the right fork leg, kids can lock out the suspension fork.

13.6 kilograms – not a super lightweight

At 13.5 kilograms, the Canyon isn’t super light. In this wheel size, there are Carbon bikes that are easily 2-2.5 kilograms lighter. But they also cost three times as much.

For the price of €699, the weight is absolutely acceptable. Especially since the tires (which can wear out quickly for kids) and tubes offer significant tuning potential.

Anyone willing to make an effort can easily shave off another 300-400 grams here. However, the base with an aluminum frame, disc brakes, and suspension fork cannot be tuned into a super-lightweight racer. The focus of this bike is not on lightweight construction but rather on a robust design that allows for everyday use.

What can be said about the specs?

The 10-speed Shimano Cues drivetrain is sturdy, has shifters specifically designed for small hands, and with the large 48-tooth cog on the cassette, it provides an easy climbing gear—without kids needing to operate a second shifter for a front derailleur at the crankset. That’s brilliant.

The Shimano MT 200 brakes can be operated with more than one finger. Kids often use two or three fingers on the lever, and that’s possible here. They provide reliable stopping power but aren’t specifically tailored to the ergonomics of small children’s hands. Nevertheless, their braking force significantly increases safety on streets and trails—and boosts confidence in the bike and their own abilities.

Features: Between Everyday Life and Sport

The Canyon Grand Canyon is a true mountain bike but also shows a pragmatic side with its frame details. A kickstand or luggage rack can be mounted if needed.

There is space for a Bordo lock on the down tube, and on the top tube, there’s an additional mounting point for a small pouch – e.g., for snacks or the house key. This way, Canyon also has kids in mind who ride this bike to school.

Final assembly
In addition to the two bottle cages that fit into the frame triangle, another bottle cage or a Bordo lock can be mounted on the down tube.
Bag setup
You can mount a small bag on the top tube, for example, to hold your house key.

Here's what our tester says about the bike:

After several weeks with the bike, our tester Lukas has also developed his own opinion on it and comes to a verdict far beyond technical details:

Conclusion on the Canyon Young Hero 24 Inch Mountain Bike

For €699, Canyon delivers a kid’s bike that can do more than just commute to school. The suspension fork performs exceptionally well even at low weights, and the geometry of the bike is designed for off-road use. Those seeking ultra-light construction will have to spend more money. If you’re looking for a robust, affordable, and versatile bike, you’ll get a great overall package here that covers everything from the ride to school to singletrack trails.
