⚙️ BAFANG M620 Mid‑Drive Intelligence
G510 · Torque SensingThe HKM-043091 is propelled by a 48V 1000W BAFANG M620 mid‑mount motor, a benchmark in responsive e‑MTB performance. Unlike cadence‑only systems, its integrated torque sensor continuously measures pedal force, delivering proportional power that mimics your natural riding rhythm. The result: intuitive climbing, controlled acceleration, and efficient battery use across rocky ascents and loose singletrack. With up to 160 N·m of crank torque, steep grades become manageable without overwhelming the drivetrain.
Real‑Time Torque Feedback
Sensor reads pedal force every millisecond, adjusting motor output seamlessly for a connected trail feel.
Grade‑Conquering Torque
160 N·m crank output pairs with low gearing to handle inclines beyond 25% with composure.
11‑Speed SRAM NX Drivetrain
Shift with confidence across an 11‑42T cassette. The SRAM NX rear derailleur and single‑trigger shifter deliver crisp, reliable gear changes even under load. This wide‑range gearing excels on both steep technical climbs and fast flow trails, reducing chain chatter and missed shifts. Designed for durability and low maintenance, the system thrives in mud, dust, and variable mountain conditions.

🛡️ Lightweight 6061 Alloy Frame · 26″ Fat Tires
Hydroformed aluminum balances low weight with high torsional stiffness. 26‑inch wheels wrapped in 4.0‑inch (approx. 102 mm) wide tires provide immense grip on sand, snow, roots, and hardpack. The voluminous tire profile enhances stability at speed and naturally absorbs small trail chatter.
190 mm Rear Shock
7.5 in (190 mm) of tunable travel absorbs rock gardens and drops. Adjustable rebound and compression let you dial in the feel for your weight and terrain.
Hydraulic Disc Brakes with Motor Cutoff
Front and rear 180 mm hydraulic discs provide consistent, powerful stopping in wet or dry conditions. The integrated brake‑cutoff sensor instantly disengages motor power the moment you pull a lever — an essential safety feature for technical descents and unexpected obstacles. Lever reach is adjustable for a personalized feel.
Front & rear, reliable heat dissipation
Brake‑actuated safety switch
🔋 Dual‑Ready 48V Architecture
The standard 48V 17.5 Ah lithium‑ion pack (840 Wh) delivers a range of approximately 19–37 miles (31–60 km), influenced by assist level, rider weight, and terrain. For longer journeys, an optional secondary battery mounts cleanly to the frame, effectively doubling your range without altering handling. An intelligent BMS protects against overcharge, deep discharge, and temperature extremes.
Removable, lockable, integrated controller
Extends range beyond 75 mi (120 km) with second pack
🎯 Rider‑Focused Adjustability
Fine‑tune reach and height to reduce fatigue on long rides.
Sensitive off the top, progressive through the stroke.
