24-inch mountain bike for youth and children, aluminum bike CROSS STELA 21-speed Shimano TZ-500
The 24-inch youth mountain bike combines a lightweight aluminum frame with versatile features, making it ideal for young riders who want to ride around town, go on bike tours, and tackle a variety of terrain. The 310 mm frame, together with the 24-inch suspension fork, provides a solid foundation for a controlled ride.
The Shimano 21-speed gearing provides a versatile choice of gears. It features a Shimano TZ500 7-speed rear derailleur, a Shimano TZ500DSDM 3-speed front derailleur, and Shimano RS35 twist shifters. The 3-chainring crankset with 24/34/42 teeth is paired with a Shimano MF-TZ50 7-speed freewheel. This provides a total of 21 gears for different riding conditions.
The youth bike uses a combination of two braking systems: a mechanical Repute disc brake with a 160 mm rotor up front and a Logan brake with 110 mm aluminum brake arms and 55 mm brake pads at the rear. The black 2.5-finger brake levers are made of aluminum and plastic.
The bike runs on Crosser X2 rims with 36 black spokes. The front wheel has a Joy Tech JY761 hub with quick release and disc brake mount, while the rear wheel has a Joy Tech JY754 hub. The Rubena Ocelot tires in 24 x 2.125 inches provide a wide contact patch.
Other features include a 600 mm-wide steel mountain bike handlebar, an 80 mm stem with a 30° angle, black Ballboss grips, a Ursus aluminum kickstand and a quick-release seat clamp. Front, rear and Herrmans wheel reflectors improve visibility.
Weighing approximately 13.05 kg, this 24-inch youth mountain bike is a versatile companion for leisure, everyday use and bike rides together.
RECOMMENDED RIDER HEIGHT: APPROX. 125–145 CM
This bicycle is delivered 92% assembled. Only the handlebars, front wheel and pedals need to be secured. Final assembly to make the bicycle ready to ride must be carried out by a qualified person.
