≈ 3‑hour charge time Quick lithium‑ion recharge · minimal downtime between adventures

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.

Frequently Asked Questions

What is the maximum speed I can expect on flat ground?
The HKM‑849939 can reach a top speed in the range of 18.6 mph to 31.1 mph (30 km/h to 50 km/h) on level ground, depending on the selected assist mode, rider weight, and terrain. Many riders find the upper end easily achievable with throttle‑only operation on smooth pavement.
How far can I go on a single battery charge?
Under typical riding conditions with mixed pedal‑assist usage, expect more than 37.3 miles (60 km) of range. Factors such as rider weight, wind, tire pressure, and the level of electric assist chosen will influence the actual distance. Using throttle‑only mode at maximum speed may reduce range, while gentle pedal assist can extend it noticeably.
Is the battery removable for charging?
Yes, the lithium‑ion battery is designed to be easily removable. This allows you to charge it indoors or at your workplace while leaving the bike secured outside. The battery locks into the frame with a weather‑resistant mechanism and can be removed with a key for added security.
Does the bike offer pedal‑assist as well as throttle?
Absolutely. The HKM‑849939 features a multi‑level pedal‑assist system that senses your pedaling input and automatically adds power. In addition, a thumb throttle lets you engage the motor on demand — ideal for starting from a standstill, crossing intersections, or giving your legs a brief rest.
What type of terrain is this mountain bike suitable for?
It is built for a wide spectrum of surfaces: singletrack, fire roads, gravel paths, and paved streets. The 27.5 × 2.4‑inch tires, combined with the robust aluminum frame and powerful motor, make it equally capable on loose climbs and urban commutes. It is not designed for extreme downhill or freeride park use where full‑suspension bikes are recommended.

Not for side sleepers
Size: Standard (Pack of 2), Style: Medium, Configuration: Hometextile
These pillows are quite soft and flat, and offer very little support. I sleep on my side and can't use these pillows. I don't know why they're recommended for side sleepers.

A pillow made of extras soft lumps and clumps. Defective.
Size: Standard (Pack of 2), Style: Medium, Configuration: Hometextile
This pillow should not even be sold. It's simple a super soft pillow with lumps of clumps of softness. Part of my head was even touching the mattress through the clumps. I ended up throwing it on the floor at 2 am and my head and neck hurt from it. I have never had a pillow of lumps before. I hope I can return this thing.
