Motor & Battery System
The HKM‑849939 is propelled by a high‑efficiency 48 V 1000 W brushless rear hub motor. This configuration places power directly at the rear wheel, resulting in a direct, responsive feel that seasoned riders appreciate. The motor’s 60–70 Nm (44.3–51.6 lb‑ft) of torque translates into strong low‑speed pull and the ability to maintain momentum on technical climbs without excessive cadence loss. Whether you are powering out of a switchback or accelerating from a standstill at a trailhead, the delivery is smooth and predictable.
Energy is stored in a robust lithium‑ion battery pack, carefully positioned low on the frame to optimize the center of gravity. With a single charge, you can cover more than 37.3 miles (60 km) under typical mixed‑terrain riding conditions. Actual range will vary based on rider weight, terrain, assist level, and weather, but the system’s intelligent controller continuously balances performance and efficiency. Recharging takes just over 3 hours, so even a lunch stop can add meaningful range.
Drivetrain & Braking
The 27‑speed gear system gives you the mechanical range to complement the electric assist perfectly. On steep, loose climbs, shift into a low gear and let the motor’s torque do the heavy work while you keep a comfortable cadence. On fast descents or paved connectors, jump to the high end and enjoy efficient cruising. The drivetrain components are selected for durability and crisp shifting, so you stay focused on the line ahead.
Stopping power is handled by hydraulic disc brakes, a crucial upgrade for any e‑bike that sees mixed weather and demanding terrain. The sealed hydraulic system provides consistent lever feel and powerful bite, even when rotors are wet or dusty. Less finger fatigue means you can ride longer and react quicker. Combined with the grippy 27.5 × 2.4‑inch tires, the braking performance inspires the confidence to push your limits.
Frame, Geometry & Tires
The foundation of the HKM‑849939 is a lightweight 27.5‑inch aluminum alloy frame. Aluminum offers an excellent stiffness‑to‑weight ratio, meaning the bike feels lively and direct under power while remaining agile enough for technical singletrack. The frame geometry is tuned for a balanced ride — upright enough for comfort on longer excursions, yet aggressive enough to attack descents with control. Subtle but thoughtful touches like internal cable routing keep the silhouette clean and reduce maintenance.
Rolling stock consists of 27.5 × 2.4‑inch tires, a width that delivers a generous contact patch for traction without excessive rolling resistance. The 27.5‑inch wheel diameter (also known as 650B) strikes a sweet spot between nimble handling and rollover capability. The 2.4‑inch width enhances stability on loose gravel, hardpack, and asphalt, and the larger air volume acts as natural suspension, absorbing trail chatter before it reaches your hands and feet.
