How about getting the kids a fully featured full susser that grows in size as they do? Could it be the one perfect bike to rule them all? Well, at least until they’re big enough to buy their own rig?

The Yuma from Propain is very popular among young bikers. No wonder as it is a full-featured mountain bike for uses from enduro to downhill, which is optimized for and “grows” with the needs of its small, light riders.

For the 2018 model, Propain and the Propain Gravity Kids team have worked together to completely overhaul the frame and launch it with a new chainstay concept. The option to install both 24″ and 26″ wheels has been retained giving the kids many years of fun with the bike.

Until now, the Yuma had been a smaller version of its big brother, Tyee, but now Propain is heading in a new direction and going with a completely distinct bike. A single pivot chainstay, in combination with the latest generation of shocks by Rock Shox with Trunnion Mount (side mounting point), provides a sensitive, high-progression response.

The new frame concept is especially suited for children’s bikes as the comparatively simpler construction with few frame bearings leads to a significantly lighter frame weight. The total weight of the Yuma is just 12.3 kg.

The frame geometry has also been completely reworked. Due to a lower frame height compared to its predecessor, the jump from the 20″ Frechdax to the new Yuma is no longer as significant, and kids find the transition a lot easier. The Yuma is recommended for heights of approx. 1.30 m and upwards. Test rider and Propain Gravity Kids team member Johann Schumacher (aged 9, 1.29 m) felt immediately comfortable and was able to handle the bike right from the start.


Propain doesn’t make any compromises on equipment and offers even young riders an overall package. The chassis with 140 mm front and rear suspension travel in the serial version consists of the Manitou Minute suspension fork and the Rock Shox Deluxe RT shock.

The Yuma is equipped with the Sram GX groupset with 1×11 gears. This wide bandwidth means that even longer cycling trips are no problem. The bike uses the reliable Formula Cura 2 piston brake. For components such as handlebars, stem, saddle, and wheels, Propain relies on its own brand, FirstRide, which specializes in lightweight and functional parts for children’s bikes.
