⚙️ 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.

❓ 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.

Great for freezing apple sauce, peanut butter, etc for a treat.
Size: Large (Pack of 1), Product Packaging: Standard Packaging
Our dog has extreme separation anxiety. When ever he even thinks we are going to leave he barks and jumps in our face. He is a mini Aussie, so he can jump high. I have researched ways to help him not freak out so much when we leave. I read that giving him something like this with some yummy frozen in it like peanut butter, apple sauce, wet food, etc. so he relates us leaving to him getting a yummy treat. He still freaks out when we leave, but not as bad because he wants the kong but also wants to remind us he doesn’t approve of us leaving, lol. It’s Kong, so obviously very high quality. It’s pretty heavy. I wish there was an in between size, this is a little too big and the smaller size isn’t big enough. So his tongue can’t quite reach the end inside. He also plays with it when it’s not filled with treats. We have a few so one can be in the freezer while he has one. Thank goodness he is a dog that doesn’t destroy stuff when we are gone, just yells at us when we are leaving. After we are gone he just pouts. But this gives him something to do and keeps him busy. It takes him quite a while to finish what’s inside.

Helps with separation anxiety, keeps dogs busy
Size: Medium (Pack of 1), Product Packaging: Standard Packaging
Have been using kongs for my labs for years. Brand new the kongs do have a strong rubber smell. Try putting the Kong in a pot with water over low fire to help reduce the smell. Stuff with favorite treats or fill with peanut butter and freeze. Will keep dogs busy and chewers with an indestructible toy

Very durable and my Dutchie loves it
Size: X-Large (Pack of 1), Product Packaging: Standard Packaging
This is one of many Kongs I have purchased through the years. This one was the extra large that was purchased for my Dutch Shepherd. Every night at bedtime, he gets his Kong stuffed with some dry food, treats, and a nubs bone to hold everything in place. He loves his Kong and runs for his crate at bedtime. Usually, he doesn’t eat the treats immediately. But sometime during the middle of the night, he will wake up and eat. Every Kong I have purchased through the years has been very durable. I highly recommend this product for all sizes of dogs.
