Uncompromised Power for Every Journey

The HKM-M4X is built around a high‑torque 800W rear‑drive motor that delivers swift acceleration and dependable hill‑climbing ability. Whether you’re merging into a bike lane or tackling a gradual incline, the motor’s instant torque response keeps you moving confidently. The scooter handles grades up to 20° (approximately a 36% slope) without hesitation, so urban overpasses and park paths feel effortless.

Instant Acceleration

Zero to full speed in just seconds thanks to the optimized motor controller that minimizes lag.

20° Hill Climb

Consistent power delivery up steep slopes ensures no route is off‑limits.

Go the Distance

Range anxiety is a thing of the past with the integrated 48V 15.6Ah lithium‑ion battery pack, boasting a substantial 748 Wh energy capacity. Under typical riding conditions (165‑lb rider, mixed speed modes, 77°F), the HKM-M4X achieves up to 28 miles (45 km) on a single charge. Even in demanding scenarios—heavier loads, colder temperatures, or continuous top‑speed runs—real‑world range remains competitive, often exceeding 22 miles. A full recharge takes merely 4–5 hours, letting you top up during a workday.

Three Speed Modes, Total Control

Adapt your ride to any environment with three distinct speed profiles. A single button toggles between Eco, Standard, and Sport modes, each calibrated for a specific use case. The intuitive LED display keeps you informed of your current mode, speed, and battery level at a glance.

Eco – 9 mph (14 km/h)

Perfect for crowded sidewalks, campuses, or when you want to maximize battery life. Gentle acceleration extends range dramatically.

Standard – 19 mph (30 km/h)

A balanced profile for everyday commuting. Responsive yet efficient, it blends speed with reliable range.

Sport – 28 mph (45 km/h)

Unleashes full motor power for swift travel on open roads. Experience thrilling acceleration and maintain higher average speeds.

Built for Comfort and Control

The HKM-M4X is engineered to iron out rough surfaces. Its dual suspension system—front fork and rear shock—absorbs vibrations from cobblestones, expansion joints, and gravel paths, keeping your ride smooth and reducing fatigue on longer trips. The sturdy aluminum alloy frame provides a rigid backbone, while the suspension travel has been tuned for a blend of responsiveness and plushness.

Front & Rear Shock Absorbers

Dual springs dampen impacts, giving you a planted feel even on broken pavement.

Dual Disc Brakes

Front and rear mechanical disc brakes deliver strong, progressive stopping power in wet or dry conditions.

All‑Terrain Ready

Equipped with 10‑inch solid off‑road tires (approx. 2.7 in wide), the HKM-M4X provides excellent grip on asphalt, packed dirt, and light gravel. The wide contact patch increases stability at speed and enhances confidence when cornering. Because they’re solid (non‑pneumatic), you’ll never worry about flats, and maintenance is virtually zero.

Smart Connectivity

Pair the HKM-M4X with the dedicated mobile app (iOS & Android) to unlock a suite of smart features. Adjust acceleration profiles, set cruise control, activate the electronic lock, and track your rides with detailed statistics. Firmware updates are delivered over‑the‑air, ensuring your scooter improves over time.

App Dashboard

Monitor speed, battery, and odometer right from your smartphone.

OTA Updates

Receive performance optimizations and new features automatically.

Portable and Practical Design

The HKM-M4X’s aerospace‑grade aluminum alloy frame is both lightweight and incredibly durable. With a net weight of approximately 40 lbs (18 kg), it’s easy to carry up stairs or lift into a car trunk. The quick‑folding mechanism collapses the scooter in under 3 seconds, reducing its footprint to roughly 44″ × 17″ × 18″ (112 × 43 × 46 cm)—compact enough to stash under a desk or in a crowded closet. An IPX5 water‑resistance rating means splashes and light rain won’t interrupt your commute.

High‑Visibility Lighting

Ride with assurance after dusk. A powerful LED headlight illuminates the path ahead, while integrated LED strip lighting increases your side profile visibility to motorists and pedestrians. Reflectors on the front, rear, and wheels provide passive safety, making the HKM-M4X a 360‑degree visible vehicle even in low‑light conditions.

Frequently Asked Questions

What real‑world range can I expect?
Real‑world range depends on rider weight, terrain, speed mode, temperature, and riding style. Under mixed conditions (165 lb rider, Standard mode, flat terrain), most users achieve between 22–28 miles (35–45 km). Riding aggressively in Sport mode or climbing frequent hills will reduce range toward the lower end.
Is the battery removable?
The 48V 15.6Ah battery is integrated into the deck for waterproofing and structural integrity. It is not user‑removable, but the scooter can be charged anywhere via the standard AC adapter.
How does the folding mechanism work?
A single lever at the base of the stem releases the lock. Fold the stem down until it clicks into the rear fender hook. The handlebars also collapse inward. The entire process takes about 3 seconds and requires no tools.
Can it handle wet roads?
Yes. With an IPX5 rating, the HKM-M4X resists water jets from any direction. It’s safe to ride in light rain or on damp pavement. However, avoid submerging the scooter or riding through deep puddles.
What is the recommended rider weight?
The sturdy aluminum frame supports riders up to 265 lbs (120 kg). Heavier riders may experience slightly reduced range and a small decrease in hill‑climbing performance, but the 800W motor remains capable.

Perfect protection for daily use
Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)
This is my go-to sunscreen for my daily use. I have stuck to a strict skin care routine and at the end, it’s extremely important to have a sunscreen to seal the deal. And this does just that. It doesn’t leave that nasty white streaks from the sunscreen and goes on very nicely. Out of my months of using this I have never been uncomfortable with it and the smell is very refreshing unlike other brands of sunscreen. Most importantly, this doesn’t feel greasy or overly slick. Perfect balance.

Great
Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)
While it is a bit thick, that can be great for sweaty summer activities (also it's purpose)! It does not leave a white cast (on me, though I am pale, I have experienced this with other sunscreens) and smells okay, not great but like a sunscreen would be expected to. It's not a super strong scent and does not burn my eyes. Sits good under my makeup as well.

Great protection and not greasy.
Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)
This sunscreen is great. It is not greasy and protects for a long time. I have had a few battles with skin cancer, but feel confident that this stuff will protect me. Yesterday was hot and sunny and my skin was still protected after 4 hours on the golf course.

Instant relief and moisturized skin well!
Size: 3 Ounce (Pack of 1), Style: Cool Down Lotion
We used the Sun Bum Cool Down Aloe Vera Lotion after getting a little too much sun on vacation, and it worked so well. It gave instant cooling relief without any sticky or greasy feeling. The lotion absorbed quickly and actually soothed the burn instead of just sitting on top of the skin like some aloe gels do. The smell is light and tropical—really pleasant and not overpowering. After applying it a couple of times, our skin felt way less hot and tight, and it definitely helped prevent peeling. We’ll absolutely be bringing this with us on every beach trip from now on! Highly recommend if you’re looking for a sunburn solution that actually works and feels good to use.

Sun Bum Cool Down After Sun Lotion
Size: 8 Ounce (Pack of 1), Style: Cool Down Lotion
I would give this more stars if I could! As someone who spends as much time as possible soaking up the sun during the summer, I’ve found a true gem in Sun Bum’s Cool Down After Sun Lotion. This product has become my go-to for post-sun care, and it’s easy to see why—it’s like gold for sun-exposed skin! With its fantastic tropical scent, skin-loving formula, and high ratings on the Yuka app for its all-natural ingredients, this lotion is a standout. Here’s a detailed look at why I highly recommend it for anyone who loves summer adventures. Ingredients and Yuka Rating One of the standout features of Sun Bum’s Cool Down After Sun Lotion is its commitment to clean, natural ingredients, which has earned it excellent reviews on the Yuka app. According to the product description, it’s formulated with soothing aloe vera, vitamin E, and coconut oil, all of which work together to hydrate and nourish sun-exposed skin. These ingredients are free from harmful chemicals like parabens, sulfates, and dyes, making it a safe choice for those prioritizing non-toxic skincare. The Yuka app, known for analyzing product safety, rates this lotion highly for its clean, natural composition, which aligns perfectly with my preference for products that are good for both my skin and the environment. This clean formula gives me peace of mind, knowing I’m not applying anything harsh after a long day in the sun. Scent and Sensory Experience The scent of this lotion is nothing short of phenomenal—it truly smells like summer in a bottle! The tropical, coconut-adjacent fragrance is light and refreshing, evoking the feeling of a beach vacation. Unlike some overpowering or artificial-smelling products, Sun Bum’s scent is gentle yet nostalgic, making the application process a delight. It’s not just about function; this lotion elevates the entire post-sun care routine with its inviting aroma, which lingers subtly on the skin without being overwhelming. Performance and Skin Benefits When it comes to performance, Sun Bum Cool Down After Sun Lotion delivers exceptional results. After hours of playing in the sun—whether swimming, hiking, or lounging on the beach—my skin often feels dry, tight, or slightly irritated. This lotion instantly soothes and cools, providing immediate relief. The lightweight, non-greasy formula absorbs quickly, leaving no sticky residue, which is a huge plus compared to some heavier after-sun products I’ve tried. My skin drinks it up, feeling soft, hydrated, and revitalized after each use. The inclusion of aloe vera helps calm any redness or mild sunburn, while coconut oil and vitamin E lock in moisture, preventing peeling and keeping my skin smooth. I’ve noticed it helps maintain my summer glow without the flakiness that can come from sun exposure. Texture and Application The texture of this lotion is a perfect balance—not too thick like a heavy cream, but not runny like some gels. It has a smooth, serum-like consistency that glides onto the skin effortlessly and absorbs in seconds. I appreciate how a little goes a long way, making the 8-ounce bottle last through many applications. For an extra cooling effect, I sometimes store it in the fridge, which feels incredibly refreshing on warm, sun-kissed skin. The lotion applies evenly, and I’ve used it on both my body and face without any issues, even on my sensitive skin. Durability and Practicality I’ve been using this lotion consistently throughout the summer, and it’s held up beautifully as part of my daily post-sun routine. The bottle is sturdy and travel-friendly, fitting easily into my beach bag or backpack. While Sun Bum notes that shipping to certain areas like Hawaii or Alaska may be restricted due to alcohol content, I’ve had no issues purchasing it locally or online for mainland use. The formula remains effective even after multiple uses in a single day, and I’ve never experienced any separation or change in texture, which speaks to its quality. Comparison to Other After-Sun Products Compared to other after-sun lotions I’ve tried, Sun Bum’s Cool Down stands out for its lightweight feel and natural ingredients. Many gels can feel tacky or sticky, and some creams are too heavy for summer use, but this lotion strikes the perfect balance. Its Yuka-approved clean formula also sets it apart from competitors that may contain questionable chemicals. While some after-sun products focus solely on cooling, Sun Bum’s inclusion of nourishing ingredients like vitamin E and coconut oil makes it a more comprehensive solution for skin recovery. Pros Clean Ingredients: High Yuka rating for all-natural, non-toxic formula with aloe vera, vitamin E, and coconut oil. Fantastic Scent: Tropical, coconut-like fragrance that smells like summer without being overpowering. Lightweight and Non-Greasy: Absorbs quickly, leaving skin soft and hydrated without stickiness. Soothing and Hydrating: Calms redness, prevents peeling, and restores moisture after sun exposure. Versatile: Suitable for face and body, great for sensitive skin, and effective for mild sunburns. Travel-Friendly: Sturdy bottle perfect for beach bags or travel. Cons Price Point: Slightly more expensive than drugstore alternatives, but worth it for the quality and clean ingredients. Conclusion Sun Bum Cool Down After Sun Lotion is a must-have for anyone who loves spending time in the sun. Its clean, natural ingredients, delightful tropical scent, and lightweight, hydrating formula make it a standout in post-sun care. My skin absolutely loves it, and the high Yuka rating gives me confidence that I’m using a product that’s good for me and the environment. Whether you’re recovering from a beach day or just need to soothe sun-exposed skin, this lotion delivers on every front. It’s become an essential part of my summer routine, and I highly recommend it to anyone looking for a reliable, skin-loving after-sun product.
