Because mountain bikes simply fascinate children, almost all major manufacturers now offer a children's MTB. However, there are a few companies that specialise in high-quality bikes for kids. Naloo from Switzerland is one of them. With the Mountain Jack 26", Naloo supplies a children's fully that allows youngsters to race through real terrain from an early age.

Naloo comes from Switzerland, but is not cheese. The company from Aargau manufactures high-quality children's MTBs based on the 29er principle. The aim is to enable youngsters to enjoy the largest possible wheels from an early age. The advantages of this are now well known. But if you take a look at the details, you will also find some clever solutions on the Mountain Jack.

Child-orientated solutions

Short cranks with a narrow Q-factor, for example, which are more suited to the anatomy of small shredders than cranks with standard dimensions. Naloo also relies on special solutions for handlebars and grips. While normal handlebars have a backsweep of approx. 8 degrees, Naloo uses a model with a 12 degree backsweep on its children's MTB. This should ensure more relaxed wrists and shoulders.

With a diameter of 25 to 28 millimetres, the grips are also particularly thin and can therefore be gripped more securely by children's hands. To mount the brake and gear levers, Naloo therefore uses a sleeve that enlarges the handlebar diameter at the corresponding points.

The Swiss have put a lot of thought into both the geometry and the equipment. This is how the Naloo Mountain Jack Kids MTB For its size, this bike has a generous reach, a steep 77 degree seat angle and a slack 65 degree head angle. The chainstays remain extremely short at 420 millimetres, which gives the 140-millimetre fully a high degree of manoeuvrability. A striking feature is the shock positioned low in the frame which, together with the low bottom bracket, allows the youngster to literally dive into the bike. Downhill, this gives an enormous feeling of safety.

Both the suspension fork and the shock in the four-link rear triangle respond finely to the low weight. On long climbs, the shock can be locked out using a small lever. The 2.35 inch wide Tyres The rubber compound also provides additional cushioning, and children also want a grippier rubber compound, at least at the front.

There is little to complain about when it comes to the equipment: the 11-speed Deore drivetrain is high-quality and changes gears precisely, the four-piston stoppers from Hayes are perfectly adjustable and brake even adults safely.

Small deductions in the B grade

Our tester, who is just 1.28 metres tall, got on well with the Naloo Mountain Jack, but complained about the excessively wide handlebars of 700 millimetres. Unfortunately, when he tried to lower the saddle, he hit nothing - the bike doesn't come with a dropper post. However, if you want to retrofit a dropper post, the cable can be neatly routed inside the frame. However, other manufacturers offer a dropper post ex works at this price.

Unfortunately, it's not available as standard: if you want a telescopic seatpost, you'll have to dig deeper into your pockets. However, the cable guide is already included.Photo: Stefan FreyUnfortunately, it's not available as standard: if you want a telescopic seatpost, you'll have to dig deeper into your pockets. However, the cable guide is already included.

Unfortunately, the stylish aluminium frame with some internally routed cables is barely protected. Although the accessory box contains a self-adhesive rubber chainstay protector, a little more frame protection in the most important places would be desirable and would certainly have a positive effect on the resale value.

Mountain Jack 20 & 24 inch
