Trek Precaliber 24 Kids Bike Review

As kids grow older, they often grow more adventurous in their riding. If your kid loves to venture from paved trails with the family to tackling neighborhood dirt trails, the Trek Precaliber 24 may just be their perfect next bike.

Stylized like a mountain bike, the Trek Precaliber is designed for kids who are antsy for a bike with a cool “shock”, but who don’t actually need the expensive components found on a true mountain bike. And for those who want to save a little on weight and price, the Precaliber is also offered without the suspension fork for $30 less!

Results of our Test Rides

To facilitate this review, we purchased a 2021 Trek Precaliber 24 with suspension (2024 model is the same) from our local dealer and put it to the test on a wide variety of terrains. This review focuses mainly on the suspension model, but the suspension and non-suspension versions of the Precaliber share all the same components except for the fork, handlebar and hubs (more about these differences below).

What type of rider is the Trek Precaliber 24 best for?

Trek Precaliber with Suspension

The perfect combination of not too technical, yet not too basic, the Precaliber with suspension is an ideal bike for adventurous neighborhood riders who never plan to actually ride in the mountains.

Providing the cool off-road look of a true mountain bike that kids love, but without the expensive high-end components that parents don’t want to pay for, the Trek Precaliber 24 is a win-win! It’s hands-down the best “recreational mountain bike” we’ve ever tested.

To be clear, the design and quality of the Precaliber’s frame is trail-worthy, but its lower-end hand brakes don’t provide the stopping power necessary for true single track riding. Additionally, the “casual use only” labeled fork isn’t designed to handle the strain from mountain trails.

However, the suspension fork does a bit more than just look cool. It’s a huge win for kids because it helps them to easily pop-up their front tire when doing jumps and hops. It also adds a bit of appreciated cushioning on the landing.

Rigid Trek Precaliber (No Suspension)

For those looking to save on some weight, Trek also offers a non-suspension version of the Precaliber 24 that comes with a rigid fork. Weighing just under 2 pounds less than the suspension version, it may be a better option for lightweight riders who don’t plan on getting really aggressive on the bike.

With the same 2.25″ wide tires as the Precaliber with suspension, the non-suspension version is also capable of hitting basic dirt trails.

Performance and Use

From powering up jumps at the DIY neighborhood bike park, to cruising through snow and mud along paved bike trails, our testers were quickly at home on the Trek Precaliber 24.

While riding up hills, the grip shifter didn’t skip a beat, and the v-brakes had no problem bringing the bike to a stop. The 2.25″ wide knobby tires were the perfect match for snow and dirt but weren’t overly noisy or rough while on paved surfaces.

All in all, we were very impressed by the Precaliber’s performance and fit, and it easily ranks as our favorite recreational mountain bike (i.e. a bike with a suspension fork that’s not designed for real mountain biking).

What size child fits on this Trek 24 inch bike?

The Trek Precaliber 24 is a best fit for kids with inseams ranging from 24″ to 28″.

The Precaliber has a seat height range of 24″ to 30.5″, but its minimum seat height should be considered to be much closer to 26″. When the seat is placed in its lowest possible position, the handlebars are much too high for the rider and makes for a very uncomfortable and awkward fit.

As you can see in the image above, our 6-year old tester with a 22″ inseam can sit on the Precaliber with the seat height set to 24″, but the bike was much too big for him. Our taller 8-year-old tester below, with an inseam of 24″, was a great fit with the seat height set to 26.5″.

Lightweight Bikes Bolster Confidence

Lightweight bikes can be a tremendous help for young riders. Ideally, a 24 inch bike should weigh less than 30% of a child’s weight.

Less weight not only bolsters confidence in their riding abilities, but also helps kids grow or maintain their love for riding! Heavier bikes are more challenging to balance, and are a lot harder to maneuver.

Trek Precaliber 24 with Suspension

As one of the few larger bike manufacturers that actually post the weight of their kids’ bike online, Trek certainly deserves a lot of praise! Trek’s listed weight for the Precaliber 24 with suspension is 26.31 lbs., which is about what we got on our scale with 26.5 lbs.

Surprisingly, the suspension model only weighs about 1.6 lb. heavier than the non-suspension model. To help offset the weight of the suspension fork, the suspension Precaliber model features an upgraded alloy handlebar and hubs (versus steel on the non-suspension model).

Compared to recreational mountain bikes in its $400 price range, the Trek is truly a lightweight. The REI Co-op REV 24 Plus is built for a similar rider (but with plus-size tires instead of a suspension fork) and comes in at 28.2 pounds!

When compared to lower-end 24 inch bikes with a suspension fork, the Precaliber comes out winner again. The $299 BikesDirect Gravity 24″ comes in at 29.3 lb., while the $299 Schwinn Ranger 24″ comes in at 30 lb.

Although heavier than higher-end true mountain bikes (such as the $679+ 24 lb. Pello Reyes), neither of our riders commented on the Precaliber’s weight and had no problems catching air around the neighborhood.

Rigid Precaliber 24

We did not have a chance to weigh the Trek Precaliber without suspension, but its listed weight is 24.73 lb. Compared to other non-suspension 24″ bikes, the Trek is similar in weight to other bikes for neighborhood riders under $400. At $449, the Priority Start 24 is a bit lighter at 23.3 lb., while the $339 Guardian 24 is slightly heavier at 25.5 lb.

While having less of a “mountain bike” style, the Priority Start 24 and Guardian Ethos are also great bikes for neighborhood riders. The Priority is unique as it contains an essentially maintenance-free internally-geared hub paired with a belt-drive, while the Guardian features a unique SureStop braking system that allows kids to easily and safely stop on a dime.

Suspension Fork for Casual Riding Only

Suspension forks on kids bikes can add up to 4 lb.+ of weight. That’s a lot – especially for a 7 or 8 year old rider. As a result, we typically only recommend bikes with suspension forks for kids who are aggressively riding true mountain bikes, and who need the extra cushioning well-made forks can provide.

But suspension forks look cool, kids want them, and Trek knows this! As a result, Trek made a clever and commendable move and put a featherweight “casual riding” suspension fork on the Precaliber 24.

While the Zoom branded fork is not designed for true mountain biking (it clearly says so on the label), the fork does provide enough bounce to allow kids to tackle small jumps (not drops!) without adding a lot of weight to the bike.

So if your little one loves to jump curbs or even over cracks along the sidewalk, the extra $30 for the suspension fork is worth the investment.

Drivetrain and Gearing

This Trek 24 inch bike comes with a Shimano Tourney 8-speed grip shifter and derailleur. According to Shimano, the Tourney series is “a basic component set for entry sports bikes and riders”.

As the lowest level of components in Shimano’s mountain line, the drivetrain certainly has room for improvements, and for really ambitious riders and parents, they could be swapped out.

For the average rider for whom the Precaliber is designed, our main complaint is with the Tourney’s bulky shifter. The large bump of the inside portion of the grip shift is too large in diameter for most kids to comfortably place their hand around it.

As a result, most kids adjust their grip to the side of the shifter, which still allows them to shift, but places their hand farther away from the brake lever. In order to brake, kids must then angle their fingers across the grip. While not a deal-breaker, it does make braking more challenging for small hands.

This same shifter, however, is very common on bikes in the Precaliber’s price range and can also be found on the Specialized Hotrock 24, the Cannondale Quick and the REI REV Plus.

Lower Gain Ratio than Higher-end Kids Bikes

The gain ratio of the Trek Precaliber 24 ranges from 1.9 to 4.9. From long paved trails to powering up dirt ramps, the Precaliber’s range presented no problems for our testers.

For those looking for a higher top gain ratio to bust out long distances on flat terrain, be aware that the Trek’s 4.9 max gain ratio is significantly lower than other brands with ranges that max out between 6 and 7.

The woom 5, Prevelo Alpha Four and the Pello Reyes all have higher ranges, BUT they are also much more expensive and are designed for beginning trail riders versus casual neighborhood riders.

Brakes Are Basic and Non-branded

The v-brakes certainly aren’t high-end, but they provided plenty of stopping power throughout our test rides. The brake levers are child-sized and adjustable to minimize the reach for younger hands.

Compared to Tektro v-brakes, the Precaliber’s v-brakes require a little more effort to pull and don’t feel as solid. Because quick stopping is essential to true mountain biking where kids can quickly reach high speeds, brakes with more stopping power are ideal for aggressive trails.

Pedals Have Wide, Grippy Platform

The Precaliber comes standard with Bontrager’s satellite platform city pedals. Our testers enjoyed the grip and wider platform the pedal provided, but they certainly have a unique style to them. One of our kid testers thought they didn’t look enough like “mountain bike pedals.”

Swapping the pedals out, however, is quick and easy with any 9/16 thread pedal set.

Color Options

The Precaliber (suspension and non-suspension) both come in Radioactive Red as well as Magenta. Although we wanted the Radioactive Red it was out-of-stock so we ended up with the Magenta which oddly enough looks pretty red!

As a comparison, here’s a side-by-side image of Trek’s Radioactive Red and Magenta. The Red is certainly lighter and brighter than the Magenta.

The suspension version of the Precaliber 24 is also available in white with pink and orange accents as well as a black with yellow and green accents.

Local Bike Shop Assembly and Support

Another major benefit of purchasing a Trek is professional assembly at your local bike shop. From brake levers to tire pressure and shifting, you can rest assured that your Trek comes ready to roll from day one. Most local bike shops also include a complimentary tune-up after several months.

When purchasing a Trek online you have the option to pick up the bike at your local bike shop already assembled. If you don’t have a local Trek dealer, some models are available to ship directly to you, but you would have to assemble the bike yourself.

Trek Precaliber 24 Bottom Line

Offering great quality and performance for the price, the Trek Precaliber 24 is an amazing bike for kids eager to tackle ambitious jumps and trails around the neighborhood, but not quite ready to hit real mountain bike trails.

Coming with or without suspension, the Precaliber also offers that look and feel of a real mountain bike, without having to pay for high-end components.
