HKM-879251 Electric Mountain Bike
Precision-Engineered e-MTB — Bafang M600, 120Nm Torque, 11-Speed Electronic Shifting
*Top speed may be electronically limited to comply with local regulations. Actual range varies based on rider weight, terrain, assist level, and conditions.
Every component of the HKM-879251 (URUS 27.5) is chosen to deliver uncompromising performance. The Bafang M600 mid‑drive motor leverages a torque sensor that measures pedal force 1,000 times per second — meaning power delivery feels instant and natural, not like an on/off switch. The 120 newton‑meters of torque let you conquer grades exceeding 35% without breaking a sweat.
The integrated 48V 17.5Ah battery uses high‑energy‑density 21700 cells, providing 840 watt‑hours. On a typical mixed ride, you can expect 19–37 miles (31–60 km) of assisted range. The battery locks into the down tube with a secure, rattle‑free mechanism and can be charged on or off the bike in approximately 5.5 hours.
The 11‑speed drivetrain is controlled by an EDS ETAP AXS electronic derailleur. Shifts happen in milliseconds with the tap of a button — no cable stretch, no barrel adjusters. The system is fully wireless and IP69K rated against water and dust. You can even customize shift speed and multi‑shift behavior via the AXS mobile app.
TEKTRO HD‑E725 hydraulic disc brakes feature quad‑piston calipers and 203mm rotors front and rear. The result is predictable stopping power with excellent modulation, so you can feather the brakes on loose descents or grab a handful when a sudden obstacle appears. The brake levers are reach‑adjustable to fit different hand sizes.
The ROCKSHOX 35S air fork offers 5.9 inches (150mm) of plush travel with adjustable rebound and compression. Out back, the ROCKSHOX DLX air shock provides 7.5 inches (190mm) of stroke, keeping the rear tire glued to the ground. Together they create a balanced, active suspension platform that reduces fatigue and increases traction on technical terrain.
The BC281 LCD display mounts cleanly on the handlebar and shows speed, battery level, assist mode, trip distance, and more. Pair it with the Eunorau GO app via Bluetooth to record rides, update firmware, and run diagnostics. The display is backlit and readable even in direct sunlight.
How long does it take to fully charge the battery?
Using the included 4A charger, a full charge from empty takes approximately 5.5 hours. The battery can be charged while mounted on the bike or removed for indoor charging.
What is the total weight of the bike?
The HKM-879251 weighs approximately 52.9 lbs (24 kg) including the battery. The aluminum frame and optimized component selection keep weight low without sacrificing durability.
Is the electronic shifting waterproof?
Yes, the EDS ETAP AXS derailleur is rated IP69K — it can withstand high‑pressure water jets and immersion. Riding in rain or through puddles is no problem.
What type of terrain is this bike designed for?
It’s built for aggressive trail riding, enduro, and technical singletrack. The 150mm/190mm travel and 2.8″ tires provide capability on rocks, roots, and loose surfaces. It also excels as a fast urban commuter on rough streets.
