⚙️ BAFANG M620 Mid‑Drive Intelligence

G510 · Torque Sensing

The 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.

📐 Frame 6061 Aluminum, hydroformed
🔄 Wheels 26″ × 4.0″ (66 cm × 10.2 cm)
⚖️ Approx. weight 59.5 lb (27 kg) with battery

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.

🔋 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.

Tune compression and rebound to match your weight and trail aggression.

❓ Frequently Asked Questions

What terrain suits the 4.0″ fat tires?
The 4.0‑inch width (approx. 102 mm) provides exceptional float on sand, snow, loose gravel, and rocky singletrack. Lower tire pressure improves traction and comfort without sacrificing rim protection.
How does the dual battery system work?
An optional second 48V pack attaches using frame mounting points. A parallel connection harness (sold separately) lets both batteries discharge evenly, extending total range up to approximately 75–100 miles (120–160 km).
Can I adjust the torque sensor sensitivity?
Yes. The backlit LCD display allows fine‑tuning of assist levels and power delivery curves to match your pedaling style and terrain preference.
Is the battery removable for charging?
Absolutely. The 48V 17.5 Ah pack is removable and lockable, so you can charge it on or off the bike.

Awesome product!!!
Size: 3 Panel-102"W, Color: Beige, Size: 3 Panel-102"W, Color: Beige
This thing is really awesome. I actually bought 2 of them and made myself a nice little enclosure to keep out any peeping Toms while I’m trying to work on my summer tan. What I was looking for is FULL privacy and this DEFINITELY provides that. Fabric is completely opaque, you cannot see anything through it which is exactly what I needed. Another huge bonus is the strips of fabric to cover the spaces in between the panels, giving TRUE privacy. This is a really well-made product, great design, great structure, and pretty easy to put together overall. The only downside is that with strong gusts of wind, it wants to tip over so as you can see I secured the bottom feet with a couple bricks to make it stable and that did the trick. But to me that is a minor inconvenience given all its other great aspects. So many other privacy dividers were still see-through… totally defeating the purpose. But this one is absolutely full privacy and PERFECT for what I needed it for!!!

Broke within an hour of assembly.
Size: 6 Panel-120"W, Color: Beige
This is of horrible quality. Within an hour of building, the feet support were broken on both ends, where they spin in place & do not stay straight to hold the divider up. Pieces of the plastic on the feet were broken simply from assembling the product. The covers for the metal poles were the only reason I bought this divider instead of other similar products, however those only cover one side of the metal poles so they are still visible from the other side. Two of these covers were also torn & not useable within an hour of assembly, one was already partially ripped on arrival & the other one was ripped simply during assembly of the product. I do not recommend this item & would have returned if I was still in the return window. I missed the return window because the product was bought during the holidays & I didn’t have time to mess with the return. I have not been able to use this product even once, the broken feet which do not stay in place make it very unstable & dangerous.

Nice quality, looks brand new even with daily use! Worth it!
Size: 6 Panel, Color: White
I got the Rose Home 6 panel room divider folding privacy screen and I LOVE it. I use it every day - extending it out to both block the sun, provide a backdrop for my plant wall, use as a backdrop for zoom calls, create privacy at night in front of the big windows and clear doors, and make impromptu study privacy walls in the office. This 6-panel has been the GOAT! Even though the screen is made of a woven paper material, it is still going strong despite daily use and has NOT broken anywhere. The frame is taller than other folding screens I've purchased and this one is also heavier and sturdy. Additionally the hinges fold open in BOTH directions (some screens only fold open in 1 direction like a Z). I use the folding screens indoors, but they have no issue with the AC or fans for wind resistance indoors. Sometimes I use them to hide storage or junk in the corner and make the room look neater. I also have a different brand that is the same material but has 8 panels and I love them both. I got 2 others that were made from synthetic canvas webbing belt/leash fabric and those break so fast - I just had to throw 1 away. This one is worth the money, even after daily use, it looks brand new!
