HKM-394707 High-Performance 72V 8000W Electric Dirt Bike

Engineered for rugged terrain and pure adrenaline — the HKM-394707 combines a formidable 8000W brushless motor, precision full-hydraulic suspension, and a long-range 35Ah lithium battery to redefine off-road freedom.

8000W Brushless Motor Massive 330 Nm (243.4 lb‑ft) of torque delivers instant acceleration across sand, mud, and rocky inclines.
35Ah Detachable Lithium Battery Ride 62–81 miles (100–130 km) on a single charge. Quick 3–5 hour recharge keeps adventures rolling.
Adjustable Full Hydraulic Suspension Soak up bumps and drops with tunable damping — confident control on the gnarliest trails.

Unleash True Off‑Road Power

The heart of the HKM-394707 is a high-efficiency 8000‑watt brushless motor, tuned for immediate throttle response. With 330 newton‑meters (243.4 pound‑feet) of peak torque on tap, the bike climbs steep grades and powers through loose surfaces without hesitation. The electronic controller optimizes energy flow, minimizing heat buildup even during sustained high‑load riding.

Max Speed Over 31 mph (50+ km/h) — thrilling trail velocity
0–31 mph (0–50 km/h) Rapid acceleration — reaches top speed in seconds
Torque 330 Nm (243.4 lb‑ft) at the rear wheel

Endurance That Matches Your Ambition

The 72‑volt architecture paired with a 35‑Ah lithium‑ion pack offers a real‑world range of 62–81 miles (100–130 km), depending on terrain and riding style. The detachable design allows you to charge the battery on or off the bike — ideal for apartment dwellers or base‑camp setups. Intelligent Battery Management System (BMS) safeguards against overcharge, overheating, and deep discharge, extending pack life cycle by years.

35 Ah Capacity 72 V nominal, 2520 Wh total energy — ample for day‑long trail sessions.
3–5 Hour Fast Charge From empty to full while you rest. Standard 110 V / 220 V charger included.
62–81 Miles Range 100–130 km on mixed terrain. Eco mode extends distance further.

Lightweight Aluminum Alloy Chassis

The frame is forged from aerospace‑grade 6061 aluminum alloy, striking the perfect balance between rigidity and low weight. This reduces overall mass for better handling and longer battery life, while maintaining exceptional torsional strength. The welded joints are double‑pass smoothed for stress distribution, and the swingarm geometry is optimized for off‑road tracking stability.

Frame Material 6061 Aluminum Alloy — lightweight, corrosion‑resistant
Max Load 331 lbs (150 kg) — accommodates rider plus gear

Race‑Ready Suspension & Braking

Both front and rear feature fully adjustable hydraulic dampers with piggyback reservoirs, allowing fine‑tuning of compression and rebound to match rider weight and terrain. The 7.5‑inch (190 mm) travel soaks up roots, rocks, and jumps. Hydraulic disc brakes with 210 mm rotors front and rear deliver powerful, fade‑resistant stopping even in wet conditions.

Fully Adjustable Hydraulic Fork Inverted design reduces unsprung weight. Rebound & compression clickers.
Hydraulic Disc Brakes Dual 210 mm rotors, sintered pads — consistent bite and modulation.

Aggressive Traction, Any Terrain

Fitted with heavy‑duty knobby tires sized F 70/100‑19 and R 80/100‑19, the HKM‑394707 finds grip on hardpack, loam, gravel, and mud. The 19‑inch rims provide ample sidewall flex for bump absorption while resisting pinch flats. Multi‑edge tread blocks are self‑cleaning in sticky soil.

Front Tire 70/100‑19 (approx. 2.75‑19) — directional knobby
Rear Tire 80/100‑19 (approx. 3.00‑19) — wide footprint for drive

Frequently Asked Questions

What is the actual range in off-road conditions?
Range varies with terrain, rider weight, and speed. On mixed trails with moderate hills, expect 68–75 miles (110–120 km). In aggressive riding or deep sand, range may be closer to 62 miles (100 km). Eco mode can extend it past 81 miles (130 km) on flat hardpack.
How do I charge the battery, and can I charge it off the bike?
The 35Ah pack is detachable: unlock and slide it out. Connect the included smart charger to any standard household outlet (110V or 220V). Full charge in 3–5 hours. The BMS prevents overcharging and balances cells automatically.
Is the suspension suitable for heavier riders?
Yes. The fully adjustable hydraulic fork and shock allow spring preload, compression, and rebound tuning. Riders up to 331 lbs (150 kg) can set sag correctly. The linkage rear suspension progression handles big hits without bottoming out.
What maintenance does the electric drivetrain require?
The brushless motor is virtually maintenance‑free. Keep the chain or belt (depending on model) lubricated, check brake pads periodically, and inspect tire pressure before rides. No oil changes, air filters, or fuel stabilizers needed.
Is the bike waterproof? Can I ride in rain or puddles?
The electrical components are sealed to IP54 standards, meaning resistance to splashing water and dust ingress. Riding through rain or shallow puddles is fine, but submerging the motor or battery is not recommended. Always dry the bike after wet rides.

Works well
Color: Silver
The stainless steel caddy quality is fine, the sticker was easy to install on the inside of my stainless steel sink. I initially used the small movable arm to hang on the hooks, and it did not keep the caddy in place. Anytime it was hit, it fell off or tilted off the hooks. Customer service followed up with me on my purchase, gave me the correct instructions with a picture, and I was able to snap the caddy into the hooks. They were responsive, listened to my concerns and answered my questions, and now it works great. I would recommend this.

It doesn’t take up so much space
Color: Silver
This is perfect for my use. I did have to place the sticker on it to hold it in place. I have a Blanco sink which isn’t smooth.

Negative reviews are misleading it definitely works just fine.
Color: Silver
Noticed the only negative reviews were because the hooks would not fit and was sort of concerned about that, but I figured it might be one of those things where it’s the person’s fault not the product. Sure enough it was. The hook fits, yea you have to push it in there with a slight bit of force, but it definitely does fit. What those people don’t realize is that by design the hooks are like that to keep a firm hold onto the tray itself. I found it funny how mad people were about that when really it’s very very simple to make it work. Nice product sticks well, seems sturdy.

Good product, lousy instructions
Color: Silver, Color: Silver
This is a good product with terrible instructions. I’ve used this adhesive strip before so I know how to install the basket & how to remove the strip. To get a snug fit position one of the basket's vertical wires in the middle of one of the horizontal bars then press down hard until you hear it snap into place, it’s now snug & will not tip over. To remove the adhesive strip I used a putty knife & wiggled it underneath the strip until I had loosened & lifted enough of it to get a good grip & pull the rest off. Mine is installed on a ceramic tile back splash not in the sink so this method did not damage the tile, can't say what it would do to stainless steel. I'm a 72 y/o woman with arthritis, if I can get the adhesive off anyone can.

Works well, but very difficult to remove!
Color: Silver
Perspective: Ive had this caddy for 3 years and it has suited me well. Over time the hooks that hold the caddy in place loosened and the caddy would occasionally fall off the side of the sink wall. Not a huge deal, just a small inconvenience. Over time it started to happen more often because the plastic hooks completely lost their grip so I decided to replace it. Well it literally took me 3 days to get it off of the side of my sink. Using different tools to jimmy it off because the adhesive is sooo strong (which is a good thing, until you are looking to remove it). It took a razor blade and several bouts of goo gone to get the whole thing off as well as the leftover adhesive. The fact that it lasted for 3 years is a testament that it is a good product, but it lost several stars for the drama and pain and suffering it took to remove. I wont be buying another one.
