This mountain bike is the ultimate choice for young racers and trail rockers who want to ride at the highest level. The Endgame was developed to withstand the challenges of demanding cross-country trails while offering first-class performance.
When it comes to speed and precision, our Endgame makes all the difference. Designed for young athletes who want to give their all on the race track, this bike sets new standards in performance and lightness.
Every detail counts – that's why we select each component with the utmost care. The result is a race bike built for peak performance. No matter the terrain, the JAISON Endgame delivers the perfect balance of speed, control, and agility.
For young racers who refuse to compromise, the Endgame is the perfect partner. It provides the ideal foundation for fast starts, precise handling, and maximum acceleration – exactly what's needed to cross the finish line first. This makes every competition a true experience!
Our race bikes are hand-assembled in Switzerland and built specifically for the high demands of racing. By collaborating with Swiss suppliers, we can individually address the needs of your young racer.
Ready for the next big moment on the race track? Then the JAISON Endgame is the right choice!
We focused on the following features:
Frame
Quality
Our frames are produced to the highest quality standards and tested according to international ISO standards.
They not only meet all requirements for impact and fatigue resistance applicable to children's bikes, but our carbon frames have also been tested with increased forces according to adult standards.
Standover Height
The top tube of our carbon frames is drawn far down, resulting in a low standover height. This allows younger riders to transition to larger wheels sooner, enabling them to benefit from the advantages of larger wheels earlier. For example, larger wheels can roll over obstacles more easily, increasing control and safety.
Geometry
We focused on a balanced stack-to-reach value for optimal control. In combination with a not-too-flat head tube angle, the bike remains extremely nimble and agile. This is an enormously important characteristic for any children's bike.
Weight
One of the most important features of a children's bike. Regardless of the category. Naturally, we strive for the lowest possible weight for our carbon frames... this is the basis of every super-light kids' bike.

Cranks
Cranks for children. A difficult matter. Children's specific needs differ significantly from those of adults here. Crank arm length is one of the characteristics of a children's bike that is often neglected. Unfortunately, crank arms that are far too long are often installed. On the one hand, an efficient cadence can hardly be achieved, and on the other hand, large lean angles in corners are impossible because the pedals hit the ground. In addition, excessively long cranks, especially for children in their growth phase, pose a risk of knee injury. We install a crank arm length appropriate for the age and size on every bike.
Another important criterion is the so-called Q-factor. This describes the distance between the two crank arms. Crank arms that are close to each other enable ergonomic pedaling and optimal conversion of pedaling force into propulsion. The Q-factor of our JAISON crank is significantly smaller than that of standard cranks. Crucial for efficient pedaling, which increases fun and propulsion.

Wheels
Lightweight wheels are a decisive factor in children's bicycles and play a central role in the riding experience and safety of young cyclists.
Lightweight wheels make handling the bicycle easier. Children can maneuver, steer, and stop the bike more easily. This promotes confidence and control over the bicycle. With lighter wheels, children need to exert less force to get the bicycle moving and keep it moving. A bicycle with lightweight wheels reacts faster to steering movements and braking maneuvers. This can be crucial in preventing accidents. Better handling and faster reactions thus contribute significantly to the child's safety. Ultimately, a bicycle with lightweight wheels is simply more fun.
That's why we choose very light aluminum rims for building our wheels, combine them with outstanding hubs with double-sealed ball bearings, and install light yet extremely stiff spokes. Jaison wheels are super light and yet so robust that they pass all tests in the test laboratory, even with increased requirements and higher forces.
3/4
Handlebar
We install ergonomically shaped handlebars on our kids' bikes to enable comfortable and safe handling for young riders. The handlebars offer a natural hand position that reduces strain on wrists and shoulders. The adapted shape with a slight backsweep improves control over the bike, which is especially important on uneven terrain and during longer rides. Furthermore, ergonomic handlebars promote better posture and help prevent fatigue, making the riding experience more pleasant and safer for children. We also adapt our handlebars to children's narrower shoulders while still providing enough width to ensure optimal ergonomics and riding stability.

Crank Arm Length IV
The length of the crank arms is one of the characteristics of a children's bicycle that is often neglected. Unfortunately, crank arms that are far too long are often installed. On the one hand, an efficient cadence can hardly be achieved, and on the other hand, large lean angles in corners are impossible because the pedals hit the ground. In addition, excessively long cranks, especially for children in their growth phase, pose a risk of knee injury.
Our crank arms are short enough to allow efficient pedaling with a high cadence, yet long enough to generate proper torque.
