Next‑Generation Lithium Power System

At the core of the HKM-647187 sits a high‑density 72V 45Ah lithium‑ion battery pack — engineered for endurance and consistent power delivery. With a formidable 3.24 kWh energy reserve, the bike achieves up to 93 miles (150 km) on a single charge under typical riding conditions. The advanced Battery Management System (BMS) continuously monitors cell voltage, temperature, and state of charge, protecting against over‑charge, deep discharge, and thermal stress. Whether you are traversing forest trails or commuting across town, the pack’s optimized energy density keeps you rolling longer between charges.

Smart BMS Protection

Multi‑layer safeguards ensure battery longevity and safety in all temperatures.

Range‑Optimized Cells

High‑grade 21700 cells deliver minimal voltage sag and extended cycle life.

Mid‑Drive Brushless Motor & Instant Torque

The centrally mounted brushless motor delivers a staggering 500 Nm (369 lb‑ft) of torque directly to the drivetrain, translating into explosive acceleration and effortless climbing on gradients up to 35°. Unlike hub‑motor designs, the mid‑drive configuration preserves the bike’s balanced weight distribution and leverages the 5‑speed gearbox for optimal mechanical advantage. The result is a responsive, natural ride feel — whether you are crawling over technical rock sections or sprinting on open fire roads. The motor’s sine‑wave controller ensures whisper‑quiet operation and smooth power modulation.

Multi‑Layer Gear Reduction

Optimized internal gearing multiplies torque while keeping the motor compact and efficient.

Sine‑Wave Controller

Delivers fluid power delivery and near‑silent operation, reducing drivetrain stress.

Lightweight Alloy Frame & Full Suspension

Crafted from 6061 aluminum alloy, the frame strikes an ideal balance between rigidity and low weight, enabling nimble handling without sacrificing durability on punishing trails. The hydroformed tubes feature reinforced weldments at high‑stress junctions, while the geometry is tuned for aggressive all‑mountain riding. Paired with a full‑suspension system — featuring adjustable preload and rebound damping — the bike absorbs square‑edge impacts and successive bumps with poise, maintaining tire contact and rider confidence at speed.

6061 Aluminum Chassis

Precision‑welded frame with optimized strength‑to‑weight ratio for trail agility.

Adjustable Full Suspension

Tune compression and rebound to match terrain, from rock gardens to flow trails.

Hydraulic Disc Brakes with Precision Control

Stopping power is delivered by a set of high‑performance hydraulic oil brakes, featuring four‑piston calipers biting on large‑diameter stainless steel rotors. The system provides exceptional modulation and fade‑resistant performance, even during prolonged descents or emergency stops at top speed. Ergonomic levers offer reach adjustment, allowing riders to tailor the engagement point for maximum comfort and one‑finger braking capability. With a dual‑circuit layout, braking force remains balanced, enhancing stability when you need it most.

Oversized Wheels & All‑Terrain Rubber

Equipped with a substantial 70/100‑19 wheel set (front and rear), the HKM-647187 rolls over obstacles with authority. The wide‑profile knobby tires (approximately 3.0‑inch section width) deliver a large contact patch for superior grip on loose soil, gravel, and mud. The 19‑inch rim diameter strikes a sweet spot between rollover capability and sidewall compliance, while the aggressive tread pattern sheds debris effectively. Whether cornering on hardpack or powering through sand, the tire and wheel combination inspires confidence at all lean angles.

5‑Speed Gearbox & Seamless Shifting

The five‑speed transmission allows riders to select the perfect ratio for every situation — from steep, technical climbs that demand low‑end grunt to high‑speed sections where cadence and motor efficiency matter. The gearbox features dog‑clutch engagement for positive, reliable shifts, and is sealed against dust and moisture. The close‑ratio spread complements the motor’s broad torque curve, enabling smooth acceleration without power gaps. A gear position sensor communicates with the controller to optimize power mapping in each gear.

Frequently Asked Questions
What is the actual range on a single charge?
Range varies based on terrain, rider weight, speed, and assist level. In optimal conditions (flat terrain, Eco mode, 155 lb rider), you can achieve up to 93 miles (150 km). Aggressive off‑road use with maximum power will reduce range accordingly. The battery management system ensures consistent performance throughout the discharge cycle.
How fast does the battery recharge?
Using the included 5A smart charger, a full charge from empty takes approximately 8‑9 hours. The battery supports faster charging (up to 10A) with an optional accessory charger, reducing charge time to around 4‑5 hours. The BMS controls charge current and temperature to preserve cell health.
Is this bike street‑legal?
The HKM-647187 is designed primarily for off‑road use. Regulations vary by region; some areas classify it as a moped or motorcycle, requiring registration and a license. Please check your local laws before operating on public roads. It can be fitted with lighting and mirrors (not included) for potential homologation.
What maintenance does the drivetrain require?
The sealed gearbox requires an oil change after the first 300 miles (500 km) and then every 1,200 miles (2,000 km). The chain (if applicable) should be lubricated regularly. Hydraulic brakes need periodic fluid inspection. The battery contacts should be kept clean and dry. Full service intervals are detailed in the user manual.
Can the battery be removed for charging?
Yes, the 72V 45Ah pack is easily removable via a key‑locked mounting system. This allows you to charge indoors or swap batteries for extended riding sessions. The pack weighs approximately 38 lb (17.2 kg).

Robust pipe & fittings with a beautiful, smooth black finish
Size: side table leg
This set of pipe & fittings for use as low table legs is heavy duty and aesthetically pleasing. Especially when the pieces are handled, the tactile sensation is much nicer than with plumbing steel pipe because this product is beautifully finished smooth. The black pipes are quite smooth as well as the fittings. The pieces are all also pretty robust, though the wall thicknesses are less than in pipe for pressurized water systems. Of course that makes sense as this product does not need to hold fluid pressure. In my view they got the heaviness factor of this product just right; it's not as heavy or robust as black pipe used in natural gas supplies, but still robust and pretty heavy. Assembled, this product is absolutely stiff and unyielding for a solid table that could hold a man's weight easily. The feet utilize a brilliant scheme so that each foot can be independently adjusted for an uneven floor. Thus a level table on an uneven floor is easily accomplished. The feet simply extend the effective leg length by screwing counter-clockwise. To prevent any shifting at the threads adding some pipe compound or teflon tape may be advised. Even masking or duct tape might work as the idea is to just fill any gaps where male threads meet female threads. The four flanges at the tops of the legs provide a wide, solid surface for attaching the table top, with either hidden screws underneath or you could through-bolt a glass table top (provided you have the skill to drill glass!). I think this product would look great with a glass top. Assembly is quick and easy. The hardest part is drilling holes underneath the table top to accept screws. No pipe wrenches are needed as the pieces screw together by hand to an adequate tightness. If any doubt whether they are tightened enough have a strong person with grippy gloves finish. The "X" in the center attaches to the legs with a very clever machine screw system tightened with the included hex wrench. This is presumably because if tightened simply by screwing the fittings, the point of snugness would not likely be where the "T" fittings are exactly vertical. The maker has solved this problem so that you are assured that all legs will be in the perfect vertical position once everything is tight. The setup is also nice and rigid once tightened. This is a huge benefit of steel pipe projects; they are really solid. The black finish is clearly very durable, like a powder coat. It appears that it will provide excellent protection against rust. Coverage is complete; I found no dings or scratches anywhere on any piece. Overall this is a very well-designed product for function and aesthetics. Perfect for a beautifully renovated warehouse condo where an industrial vibe is desired in a rock-solid table that won't shift around. The smoothness of the pipe is top notch. I've used lots of pipe in projects, some of it actual water pipe and some decorative pipe such as this. I've never seen better quality decorative pipe as this maker put in the effort to finish it beautifully smooth. At currently $34.99 I find the price quite reasonable too.

Good DIY Pipe Legs but Powder Coat Quality Lacks
Size: side table leg, Size: side table leg
These industrial style pipe legs make building a DIY end table easy and the kit saves a trip to the hardware store. The fittings go together normally and assembly is simple. Comes individually wrapped. My main issue is the powder coating looks and feels cheap and rubs off easily. The pipes already had marks from touching each other from unboxing. If you do not mind some wear on the finish over time this is a decent purchase. The metal at the hardware store will be thicker and more durable but will cost more. I’d recommend based on ease of having a kit and it being delivered saving me a trip.

Stable, attractive, and easy to turn into a table with your choice of top
Size: side table leg
The X-shape of the table legs - constructed with solid metal flanges, T-joints, X-joints and 1-inch diameter pipes - provides a strong and sturdy base for a wood top. The legs have adjustable feet pads to prevent scratches and ensure stability. Assembly of the legs is relatively simple (the instructions are clear) but you will need your own tools to attach a top. The industrial design is especially well suited to rec room or finished basement use. I am adding a 28" diameter raw edge slab of wood from a recently felled tree as the top and it is very attractive. (Photo unavailable because after I made certain it would work I sent the slab out for drying and finishing.) If you want a custom table and have a particular piece of wood you want to use, these legs are an excellent choice.

Very nice kit: Beware it is NOT heavy duty plumbing pipe though!
Size: side table leg
I want to give this kit a high rating, but I need to address the "truth in advertising" bit since there may be an important disconnect between what you think you are getting and what actually comes in the box. Black plumbing used for shelving or table legs is part of an important niche in interior design. I like the industrial loft look myself and have a variety of glass, steel, and masonry elements in my home. This kit fits that look and provides plenty of "strength" for most domestic uses, like shelves or coffee tables. But they are NOT "industrial pipe" or "maximum durability pipe." Note the phrase "cast iron finish feet," which together with the other claims might lead you to think these are cast plumbing fittings. They are NOT! The feet and flanges feel like electrical conduit fittings, and the pipe sections are likely aluminum. They might be electrical or they might be multi-use, lightweight pipe. While all this might lead you to think that you're getting a truly retro, heavy-duty pipe kit made of black plumbing pipe, you are not. But, does it matter? Depends. I find the lighter pipe's smooth finish a nice "tone-down" from the rough plumbing look. All together, this kit provides plenty of strength for most furniture and the rustic pipe look, but with a nicer, lighter finish. To me that is a plus--this is a very nice kit and costs less that if you'd pieced it together from real plumbing parts (I priced it out to compare), and looks retro but cleaner. I knew what to expect because while I got this kit free on Vine, I had purchased a nearly identical kit from another seller last year. So, I'm giving it 5 stars for what it actually is and for the price, JUST BE AWARE THE NARRATIVE IS MISLEADING. Which is unfortunate because just like some people might want the heavier pipe, I'm betting more would be attracted to the look with a cleaner, lighter feel.
