HKM-103635 Electric Dirt Bike

Engineered to redefine off-road excitement, the HKM-103635 merges raw electric torque with agile chassis dynamics. Whether you are a veteran rider or a newcomer to dirt tracks, this machine delivers instant acceleration, silent operation, and zero emissions — all wrapped in a durable, lightweight package.

High-Output Powertrain

The heart of the HKM-103635 is a robust 6500W brushless DC motor, tuned specifically for off-road performance. Instant torque delivery eliminates the lag found in traditional combustion engines, giving you explosive acceleration from a standstill. A sine wave controller ensures smooth power modulation, reducing jerky throttle response and enhancing traction on loose surfaces. The powertrain is fully sealed against dust and water splashes, meeting IP65 standards for critical components, so creek crossings and muddy trails won't slow you down.

Removable High-Capacity Battery

A 72V 30Ah lithium-ion pack provides 2160Wh of energy, carefully optimized for sustained trail riding. Depending on terrain, riding mode, and rider weight, you can expect a real-world range of approximately 41 – 62 miles (66 – 100 km) on a single charge. The battery uses automotive-grade 21700 cells and an advanced Battery Management System (BMS) that monitors temperature, voltage, and current in real time, protecting against overcharge, over-discharge, and short circuits. The pack is removable, allowing you to charge it indoors or swap in a spare for extended adventures.

Smart BMS Protection

Active balancing, temperature cutoff, and cell-level monitoring guarantee longevity and safety.

Eco / Sport / Turbo Modes

Selectable power delivery to prioritize range or maximum adrenaline with a handlebar switch.

Lightweight Alloy Frame & Adjustable Suspension

A twin-spar aluminum alloy frame keeps dry weight at just 165 lbs (75 kg), making the bike nimble and easy to maneuver in tight single-track or rocky climbs. The front end features an inverted fork with 8 inches (203 mm) of travel, while the rear monoshock provides 9 inches (229 mm) of travel, both fully adjustable for compression and rebound damping. A ground clearance of 12 inches (305 mm) allows you to roll over logs and ruts without hesitation. The wheelbase spans 55 inches (1400 mm), striking a balance between high-speed stability and low-speed agility.

Braking & Traction

Stopping power comes from hydraulic disc brakes with 220 mm rotors front and rear, offering precise modulation and fade-free performance even during aggressive downhill runs. The 19-inch front and 18-inch rear off-road tires (70/100-19 and 80/100-18) feature deep, self-cleaning tread blocks that grip loose dirt, gravel, and hardpack equally well. A lightweight spoked wheel set absorbs impacts and reduces unsprung weight for better suspension response.

Digital Instrumentation & LED Lighting

A backlit LCD display sits behind a protective lens, clearly showing speed, battery state of charge, odometer, trip meter, and selected riding mode. The display is daylight-readable and automatically adjusts brightness. An integrated LED headlight provides a sharp, wide beam for twilight rides, while the LED taillight enhances visibility to others. All lighting and electronics are powered directly from the main battery, eliminating the need for separate wiring or auxiliary batteries.

Built to Endure

Every component has been selected for rugged off-road use. Stainless steel fasteners resist corrosion, while high-impact plastic body panels shrug off roost and branch strikes. The ergonomic seat, set at 34 inches (864 mm), accommodates a wide range of rider heights and allows easy weight shifts during aggressive cornering. The bike supports a maximum payload of 265 lbs (120 kg), making it suitable for adult riders carrying gear.

Ride Responsibly, Explore Quietly

Electric propulsion means near-silent operation, allowing you to enjoy nature without disturbing wildlife or other trail users. The absence of exhaust emissions makes this bike permitted in areas with strict environmental regulations. Regenerative braking contributes to energy efficiency during deceleration, subtly extending your range on hilly descents. The HKM-103635 is a modern solution for riders who demand performance without compromise.

Excellent watch!
Rapid delivery and processing (domestic US). It's a Hamilton...I was surprised by the weight of this timepiece compared to my Seiko GMT. I love the 24-hour on the dial when dealing with military time.

Great looking color scheme, but the same flaws as the other color variants of this model.
This review is for the 43mm white dial variant with blue ceramic bezel. Everything is built exactly the same as the black and blue variants other than the colors. I’ve already reviewed the black variant separately but updated the review for this white dial version. Like probably 99% of watch enthusiasts, most of my watches have black or blue dials. Those are the most common/popular dial colors for a reason, they look good and they’re the most versatile. But because I already have so many of those, I find myself always on the lookout for a good looking white dial to add to the collection for a little variety. And even more than just a white dial, I really love a red, white, and blue color scheme. I’m a patriot, proud to have served, and to rep our country’s colors anytime I can. It makes it even better that this watch is made by Hamilton, a brand with a rich US military history that has retained its American name, even if it’s no longer an American company and is now Swiss made and headquartered. But out of all the different watches I’ve bought over the years, Hamilton has been the most frustrating. While it has made great strides in the last few years improving a lot of the things watch enthusiasts care about, such as higher end materials, improved designs, much better lume - there seems to always be at least one cheaply made part that disappoints. Pros: Great looking watch overall, it’s already hard enough to find a good looking white dial watch, let alone one with a red, white, and blue color scheme. 300m water resist (screw down caseback and crown). Accurate and reliable automatic movement. 80 hr power reserve with antimagnetic Nivachron hairspring. Thin for such a large and heavy watch with 300m water resist. Very good lume. Bracelet uses pins and collars for sizing, which is much more durable than cotter pins or screws. I never worry about a pin and collar system coming loose on a bracelet. A lot of bracelets on watches in this price tier, and some even higher (I’m talking to you, Mido and Longines!!!) are held together with cheap cotter/split pins. Cons: No date. The only people who prefer no date are watch collectors, and this is not a collector’s watch. For people who actually wear their watches daily, having the date or day/date is always preferable. Bracelet is old fashioned and needs to be modernized. No quick release spring bars, and no on the fly adjusting clasp. Pins and collars can be a little harder for some people to size, although I have no problems sizing and actually prefer them. Powermatic 80 based movement can be more difficult for traditional watchmakers to service/regulate. On the heavier side, but I’m used to even heavier watches, so it doesn’t bother me. EXTREMELY CHEAPLY MADE LITTLE LUME PIP ON THE BEZEL THAT BREAKS OFF EASILY!!! My measurements: Weight, head only: 99g. Weight, full bracelet: 116g. Weight total: 215g. 43.8mm case diameter. 47.1mm including crown. 43.0mm at bezel. 33mm approximate dial diameter without bezel. 22.0mm lug width. Bracelet tapers to 20mm at the clasp. 52.0mm lug to lug. 12.8mm thick. 7.5mm diameter crown. My wrist is 7.375” and 60mm across for reference in the pics. I’ve had the watch for a few years now. The look/styling of the watch is great. It has some classic Hamilton military looks due to the 24 hour Arabic numerals, the kind of matte, textured white dial (more on that in a bit), and mostly brushed finishing on the case and bracelet, while retaining some polished bits for styling versatility. But this white version is definitely not as versatile as the black one. On the black one, the only pop of color is on the red tipped seconds hand. That one (depending on the strap you put on it) would look equally at home for military use on a rubber or nato, a T-shirt and jeans with any strap or bracelet, and even with a suit when paired with a dressier strap. This one has that same red tip on the seconds hand, but with its white dial, bright blue bezel, along with the polished, bright blue indices and handset - it looks much less serious. I think it would look fine with a T-shirt and jeans and up to business casual, but not much otherwise. Regarding the dial, it’s much more interesting in person than you can tell in the pics. Nicely polished/finished blue indices and handset that turn an almost electric blue when hit by the light, but it’s the texture of the dial that I really like. I have no idea what it’s made of. The texture doesn’t look like it’s just from some kind of paint, it has a very subtle metallic sheen, almost like a very faint glitter. Maybe the best way to describe it would be if you were to take a shiny white metal and then sand it down to give it a matte finish, but you could still see hints of a glittery shine - that’s what it looks like. Visibility is great too. In particular, I find white dial watches that use dark outlines for the hands and indices are the most clearly visible at a glance. Also, dive watches (or any watch with an outer rotating bezel) need to be larger like this one because those bezels take up a lot of the diameter. The lume is much stronger and longer lasting than on previous iterations. This one uses blue lume instead of the green on the black version, and seems to be almost as strong and long lasting, although the green always looks brighter to me in the dark. This lume is still visible on camera even at the two hour mark (and the camera has a much harder time picking up dim light than our eyes can when adjusted to the dark), which means it’ll be easily visible in the dark all night. The antireflective (AR) coating is improved from older models and helps reduce some glare, but there are some angles you’ll find it difficult to see the time. Out of those two, the lume is definitely more important in everyday life. A good AR coating is a bonus, but less of a priority, especially at this price tier. The movement is also great, again especially at this tier. The Powermatic 80 movement is always reliable. 80 hr power reserve, laser regulated at the factory. I have 3 of them in various watches, all of them run easily within the COSC spec of -4 to +6 seconds per day. For this one in particular when fully wound, on the timegrapher it settled down at +2 seconds per day dial up, then +6 spd crown left (12 o’clock down). Its lifetime average has been +1.3 spd over 120 non consecutive days (a week or two at a time) that I actively tracked when on winder or on wrist around the house. The bracelet is a weak point. No on the fly adjust capability and no quick release spring bars. I never even wore the watch on the factory bracelet because of all that, I swapped it out immediately. I can’t wear a watch bracelet that doesn’t have the on the fly adjust capability anymore. Once you’ve had it on other watches, you can’t go back. The glossy ceramic bezel looks good and will be very durable and scratch resistant compared to aluminum. The gloss goes well with the polished bits on the dial, knurling, bezel, and crown. It has 60 minute clicks (which I prefer, makes it much easier to use the bezel even for simple things like counting instead of timing) with a solid feeling, notchy action. It was extremely difficult to move the bezel when I first got the watch because it was very stiff, but also because it has shallow knurling, and it’s smooth and polished, so it lacks grip. It’s extra hard to turn when hands are slippery from water, and almost impossible when from soap or oil. The bezel action did eventually loosen up over time (in the beginning I used to just sit there and constantly rotate the bezel to loosen it up while watching tv), and now it’s much easier to turn. But the bezel and crown knurling could definitely be improved for better grip. But the worst part, and the reason why I’m so dissatisfied with this watch - the lume pip is a little unprotected bead that seems to be just glued into the bezel. On the black version, very early on, after only a few times of wearing the watch - that lume pip broke off, and I didn’t notice until later because I hadn’t banged the watch against anything that would’ve made me check to make sure it wasn’t damaged. I never even noticed before whether lume pips were protected until my experience with that watch. Now I always make sure they’re shielded before I buy. I hate having a watch knowing a piece is missing, even if I’m the only one who knows. I bought this white version right after the black one, but before the lume pip on the black one broke off - so I’ve never worn the white version outside the house because I want to keep it intact. I should just get over it and enjoy the watch for what it is, and let the lume pip break off on this one too. It is such a waste not to wear such a good looking watch. It’s something I’ve always noticed about Hamilton watches - there always seems to be at least one part that’s made cheaply and not as durable as the rest of the watch. There’s a very simple way to fix that problem - either make it with a fully protected lume pip, or get rid of the lume pip altogether and make the bezel bidirectional, since without the lume pip it wouldn’t meet diver requirements anymore anyway. That would change the watch from a diver to more of a pilot watch, but let’s face it - 99.99% of people aren’t diving with these, we buy divers for their water resistance/durability but don’t need a unidirectional bezel for diving purposes. Bidirectional is much more functional for timing things in everyday life. And the best type of bezel would be a bidirectional, 60 click, 12 hour bezel with full minute markings. Then you could not only use it for timing, but also to track a second time zone. That would be a total homerun. In addition to that, add better knurling on the bezel and crown for better grip, quick release spring bars for the bracelet along with an on the fly adjusting clasp, at least a date (or better yet a day/date), then it would be a 5/5. Those should not be expensive additions either, they’re all very simple and relatively cheap modifications. All of that would take this watch to its highest potential in its price tier. Since product quality is always relative to its price, if the lume pip issue were fixed, without any other changes, it would be a 4 - good, not yet great. But because this has such a cheaply made piece that breaks off so easily, it gets dropped to a 1. That’s inexcusable on anything in the $1k+ tier. A lot of watches at even the sub $500 tier have shielded lume pips so that they won’t break off.

The "Lazy Professional" Look: Is Hands-Free Luxury Actually Real?
Size: 9.5, Color: Black Napa Leather
Living down here in Florida, my footwear needs are pretty specific. It’s hot, it’s humid, and I spent half my life rushing from the car into work or a meeting. I’ve reached that age where I value efficiency just as much as style—maybe more. I’ve been eyeing the Marc Joseph New York Hands-Free Slip-on Penny Loafers for a while, and after putting them through the wringer, here is the honest truth from someone who just wants to look sharp without the hassle. The "Just Step-In" Reality Look, the big selling point here is the "Hands-Free" tech. We’ve all seen the commercials for those athletic slip-ins, but finding that in a legitimate leather penny loafer is a different game. Does it work? Yes, surprisingly well. The heel counter is firm enough that it doesn’t collapse when you slide your foot in, but it doesn’t feel like a piece of plastic digging into your Achilles once you’re in. For those of us who are tired of bending over or hunting for a shoehorn every morning, this is a genuine quality-of-life upgrade. The Florida Factor: Comfort and Style The leather is actual calfskin (on most models), which is a must for the Florida heat. Synthetic shoes turn into a sauna within ten minutes, but these breathe reasonably well. The aesthetic is classic—it’s a "professor" shoe through and through. You can wear them with chinos and a blazer for work or throw them on with some nice jeans for a weekend lunch. Inside, they’ve got a gel heel insert and a padded footbed. It’s not quite "walking on a cloud"—let’s not over-hype it—but it’s a massive step up from the hard, flat soles of traditional dress loafers. I’ve spent four hours on my feet lecturing, and my arches didn’t hate me by the end of the day. The Sizing Gamble Here’s where you need to be careful. The consensus from other guys (and my own experience) is that the sizing is a bit of a coin toss. They tend to run a little large and sometimes wide. If you have narrow feet, you might find the sides "gaping" or flaring out when you walk, which kills the sleek look. I’d recommend ordering a half-size down if you’re usually between sizes. The Breakdown The Pros: True Hands-Free: You can actually put these on while holding a coffee and a briefcase. No hands needed. Legit Materials: The calf leather feels premium and smells like the real deal. Versatility: Perfectly bridges the gap between a "car shoe" and a formal loafer. Comfort: The gel insert makes a noticeable difference for long-duration wear. The Cons: Sizing Inconsistency: They can run wide, leading to some "heel slip" if you don't get the perfect fit. Break-in Period: The heel is stiff by design (to allow for the slip-on feature), so expect a day or two of minor stiffness. Price Point: They aren't cheap, though often on sale. Value for Money Are they worth it? If you’re comparing them to high-end Italian brands that cost $500, these are an absolute steal. They look 90% as good for a fraction of the price. However, if you're used to $60 mall shoes, the jump to $150+ might feel steep until you realize you’re paying for the convenience of never having to touch your shoes to put them on. For a daily driver in a professional setting, the value is definitely there.

Step In Look Good
Size: 11.5, Color: Cognac Napa Leather
I am wearing these shoes as I write this review, and they look and feel great. I have a bit of a disability with drop foot on the right leg and bilateral neuropathy and have been wearing step in shoes for about 10 years. But the first company that introduced leather dress and casual shoes stopped making them and now only makes sport and casual shoes. So I have been searching for some that meet my need for shoes like this and this company has given me three pairs, so far. Easy to get into, comfortable to wear, and good looking. And they take polish very well, too. (Remember how to do that?). We may buy another pair or two in different styles as well.
