Mountain Hardtail
At first glance, this is a classic mountain hardtail — a bicycle with a front suspension fork designed for confident off-road riding. The Rock Shox Gold 35 air-oil fork has up to 120mm of travel and is equipped with a lockout mechanism. The lockout feature allows you to disable the fork to conserve energy when climbing or at high speeds on smooth asphalt roads.
Pedal Assistant
The increased thickness of the bottom tube of the frame indicates the presence of a built-in battery with a capacity of 630 Wh, which powers the electric motor in the bottom bracket. The electric drive assists in pedaling but does not provide fully independent movement. Using the pedal assistant, the bicycle can reach speeds of up to 25 km/h, and the range is up to 100 km on a single battery charge.
High-Level Components
The KROSS Level Boost 3.0 2025 is built on quality Shimano SLX components and complemented by Shimano Deore hydraulic disc brakes. The bicycle is equipped with 29-inch wheels with WTB Ranger Comp tires 2.4 inches wide. Additionally, the model comes with a convenient and informative onboard computer mounted on the handlebars.
