Kellys Lumi 30 20" aqua children's bike (79557)

The Kellys Lumi 30 20" aqua children's bike is a product designed with young cyclists aged 7 to 9 years and a height of 120 to 135 cm in mind.

Drive Components

The key drive element in the Kellys Lumi 30 bike is the KMC Z6 chain, which ensures smooth power transmission. The PROWHEEL crankset with a 32T chainring and 140 mm length is tailored to the needs of younger riders. The bike is equipped with a SHIMANO MF-TZ20-6 cassette with a gear range of 14-28T, which, combined with 1x6 gears, allows flexible adaptation to riding conditions.

Control and Comfort

The Kellys Lumi 30 is equipped with SHIMANO SL-RV200-6R Revoshift shifters, which facilitate gear changes. The steel RiseBar handlebar with a diameter of 25.4 mm and a width of 550 mm provides a comfortable riding position. The grips ensure a secure hold. The KLS Junior saddle is designed with the child's comfort in mind during long rides.

Construction and Materials

The Kellys Lumi 30 bike uses forks made of hi-ten unicrown steel, which provides adequate durability. The hubs are made of a lightweight alloy and feature 28 holes, supporting 20-inch wheels. Steel spokes add durability to the construction. The bike is not equipped with suspension, which simplifies its design and reduces weight.

Safety and Additional Information

The set includes pedals, which is an essential element for the full functionality of the bike from the moment of assembly. Thanks to the threadless a-head design, the headset ensures precise steering. The Kellys Lumi 30 is an excellent choice for children who want to develop their cycling skills.
