HKM-890067 Electric Fat Bike

Command the terrain. Redefine your ride.

The HKM-890067 merges raw electric power with rugged fat‑tire capability, engineered for riders who demand more. A 1500‑watt brushless motor, high‑capacity lithium battery, and all‑terrain geometry let you conquer city streets, sandy paths, snowy trails, and rocky inclines with unwavering confidence. Every component is selected for endurance and control, from hydraulic disc brakes to a flexible 7‑speed drivetrain. Whether you're commuting off the beaten path or chasing weekend adventures, this e‑bike delivers a smooth, stable, and exhilarating experience.

Technical Highlights

1500W Brushless Motor

Rated 1500W brushless hub motor delivers instantaneous torque. Peak efficiency with minimal maintenance.

19–31 mph (30–50 km/h)

Adjustable top speed to match terrain and local regulations. Thrilling acceleration on demand.

48V 18Ah Lithium Battery

Removable, lockable pack with intelligent BMS for cell balancing, overcharge, and temperature protection.

25–37 miles (40–60 km) Range

Real‑world riding range per charge, depending on assist level, terrain, and rider input.

20" x 4.0" Fat Tires

Ultra‑wide, puncture‑resistant tires provide exceptional float over sand, snow, mud, and loose gravel.

Hydraulic Disc Brakes

180mm rotors front and rear deliver consistent, fade‑resistant stopping power in wet or dry conditions.

7‑Speed Gearbox

Wide‑ratio cassette lets you spin efficiently on climbs and maintain cadence at higher speeds.

Steel Frame · 330 lbs (150 kg) Capacity

Reinforced high‑tensile steel frame absorbs vibration and supports heavy loads with confidence.

8–10 Hours Full Charge

Convenient overnight charging via standard AC outlet. Smart charger prevents overcharging.

Propulsion & Power Management

The heart of the HKM-890067 is a maintenance‑free 1500‑watt brushless DC hub motor. Unlike brushed motors, its electronic commutation eliminates friction and sparking, resulting in higher efficiency, silent operation, and a longer service life. The motor controller is tuned to deliver smooth acceleration from standstill, with a progressive power curve that prevents sudden jolts—ideal for loose terrain where traction matters. Five levels of pedal assist let you dial in exactly how much support you want, while a thumb throttle provides instant full power whenever you need to clear an obstacle or merge into traffic.

Intelligent Battery System

A 48‑volt, 18‑ampere‑hour lithium‑ion pack provides the energy backbone. The cells are arranged in a configuration that balances weight and range, and are housed in a rugged, IP65‑rated case that resists dust and water spray. The built‑in Battery Management System (BMS) continuously monitors individual cell voltages, temperature, and discharge current. It automatically balances cells during charging and protects against overcharge, deep discharge, and short circuits. You can charge the battery on or off the bike, and a lock mechanism secures it to the frame when parked.

Real‑World Range & Efficiency

Range is influenced by several variables: rider weight, assist level, terrain gradient, tire pressure, and ambient temperature. In optimal conditions with moderate pedal input on level ground, expect approximately 37 miles (60 km). In more demanding scenarios—soft sand, steep hills, heavy throttle use—the range settles around 25 miles (40 km). The energy‑saving Eco mode extends distance further, while Sport mode unlocks the full 31 mph (50 km/h) top speed. A backlit handlebar display provides real‑time speed, battery state‑of‑charge, trip odometer, and assist level, so you can manage power consumption proactively.

Chassis & All‑Terrain Capability
Fat Tire Engineering

The 20‑inch wheels are wrapped in 4.0‑inch wide tires that operate at low pressures (typically 5–30 PSI). This creates a large contact patch that spreads the bike’s weight, preventing sinkage in soft surfaces. The knobby tread pattern sheds mud and provides lateral grip on off‑camber trails. On pavement, the compliant rubber compound absorbs road chatter, reducing fatigue during long commutes. The tires are also reflective along the sidewalls, enhancing nighttime visibility.

Frame Durability & Ergonomics

The step‑over frame is constructed from reinforced high‑tensile steel, known for its natural vibration‑damping characteristics. The geometry positions the rider in an upright posture, reducing strain on the lower back and wrists. A wide, padded saddle and adjustable handlebar stem accommodate a broad range of rider heights—from 5'4" to 6'4" (162–193 cm). Welds are double‑pass for strength, and the frame is finished with a corrosion‑resistant powder coat. Integrated bosses allow mounting of rear racks and fenders (accessories sold separately).

Load‑Bearing Confidence

With a maximum payload of 330 lbs (150 kg), the HKM-890067 can comfortably carry a rider plus cargo. The reinforced rear triangle and heavy‑duty spokes are designed to handle the additional stress. Whether you’re a larger rider or planning a bikepacking trip, the structure delivers predictable handling without flex or wobble.

Control & Safety
Hydraulic Stopping Power

Front and rear hydraulic disc brakes with 180mm rotors provide the decisive stopping force required by a heavy e‑bike at speed. The sealed hydraulic system self‑adjusts for pad wear and eliminates the need for frequent cable tensioning. Lever modulation is precise—you can feather the brakes for gradual deceleration or clamp down firmly for emergency stops. Stainless steel rotors dissipate heat efficiently, preserving performance on long descents.

Adaptive 7‑Speed Drivetrain

A 7‑speed rear cassette, shifted by a precise index thumb shifter, allows you to match your pedaling cadence to the terrain. Low gears make steep inclines manageable even with minimal motor assist; high gears let you contribute meaningfully at top speed without spinning out. The single chainring up front simplifies operation and reduces maintenance. A chain guide prevents derailment on bumpy trails.

Integrated Lighting & Visibility

A high‑output LED headlight and a multi‑mode rear light are integrated into the electrical system, powered by the main battery. The headlight casts a wide, bright beam for night riding, while the rear light functions as a steady glow or flashing alert. Reflective tire stripes and pedal reflectors further increase your presence to motorists.

Frequently Asked Questions
What is the actual top speed?
The motor can propel the bike to between 19 and 31 mph (30–50 km/h) depending on assist level, rider weight, terrain, and local legal restrictions. The speed can be electronically limited to comply with regional e‑bike regulations.
How far can I travel on one charge?
Typical range is 25–37 miles (40–60 km). Using Eco mode and contributing moderate pedaling effort can extend range toward the upper limit. Aggressive throttle use, steep hills, or soft surfaces will shift range toward the lower end.
Can I remove the battery for charging?
Yes. The battery pack is removable and can be charged indoors. It locks securely to the frame with a key, and a single charge takes 8–10 hours using the supplied smart charger.
Is this bike suitable for off‑road use?
Absolutely. The fat tires and powerful motor excel on sand, snow, mud, and gravel. The sturdy frame and hydraulic brakes provide the control needed for rugged trails. However, it is not designed for extreme downhill or jump‑style mountain biking.
Does it have pedal assist and throttle?
Yes. The bike offers five levels of pedal assist plus a thumb throttle. You can ride using only throttle, only pedal assist, or a combination of both.
What is the maximum rider weight?
The maximum carrying capacity is 330 lbs (150 kg), which includes the rider and any cargo. The steel frame and heavy‑duty components are engineered to maintain stability at this load.
How long does assembly take?
The bike arrives 85% assembled. Most riders complete the final steps—attaching the front wheel, handlebar, and pedals—in about 30–45 minutes using the included tools and instructions.
Is the bike waterproof?
The electrical components are rated IP65 for resistance to dust and low‑pressure water jets. Riding in rain is safe, but submerging the motor or battery should be avoided.

Beef tallow you need to buy!
Color: Unscented (1 pack)
I have tried other beef tallows & this one is hands down THE BEST! I love how cheap it is and it works wonders for my acne and my dry skin. It’s not greasy at all & definitely hydrates the skin. The scent is a light nice smell! I Love the smell of this. Applying it is very easy.

Honestly great choice
Size: Size 4 (104 Count), Color: Wild Thang + All the Alpacas
’ve tried several diaper brands over the past year, and these honestly surprised me in the best way. The Honest Company Comfort Dry diapers feel noticeably softer than many mainstream brands, and I immediately appreciated that they’re hypoallergenic and designed for sensitive skin. My little one is prone to irritation, but we’ve had zero redness or rashes since switching. Absorbency has been excellent for daytime use. We use Pampers overnights for night time. They hold up well during long errands, naps, and active play without sagging or leaking. The fit is snug without being too tight around the waist or legs, which helped prevent blowouts better than some pricier brands we’ve tested. This is huge for us cause her blow outs have literally been to the edge of the diaper and it catches it!! Another thing I really like is that they don’t have a strong chemical smell like some disposable diapers do. The material feels breathable, and the cute prints are an added bonus without sacrificing performance.

An Honest-to-Goodness Review: Diapers That Deliver Divine Comfort!
Size: Size 6 (68 Count), Color: So Delish + It's a Pawty
As a parent, you're constantly seeking products that offer both peace of mind and genuine quality for your little one. And let me tell you, when it comes to diapers, The Honest Company has truly answered our prayers. After putting their diapers through the ultimate test of babyhood – from explosive blowouts to long, sleepy nights – I can confidently say that these are not just good diapers; they're divine. First Impressions: Aesthetically Pleasing & Thoughtfully Designed Right out of the box, Honest diapers stand out. Gone are the days of boring, clinical-looking diapers. Honest offers an array of adorable, stylish prints that make diaper changes a little more fun. Seriously, who knew a diaper could be a fashion statement? But it's not just about looks. Absorbency That Works Wonders (Even Overnight!) This is where Honest truly shines. The absorbency of these diapers is nothing short of miraculous. I've used countless brands, and few can hold a candle to Honest's ability to keep my baby dry, even after a full night's sleep. The plant-based core is incredibly effective at wicking away moisture, preventing diaper rash and keeping sensitive skin happy. No more waking up to a soaked crib sheet or a fussy baby due to dampness! The Verdict: Worth Every Penny! Yes, Honest diapers might come with a slightly higher price tag than some conventional brands. However, the superior absorbency means fewer diaper changes (especially overnight!), and the gentle, plant-based materials mean fewer instances of diaper rash, which ultimately saves on creams and discomfort. When you factor in the peace of mind, the adorable designs, and the eco-conscious efforts, The Honest Company's diapers are an investment that truly pays off. If you're looking for a diaper that prioritizes your baby's comfort, health, and even offers a touch of style, look no further. Honest diapers are, without a doubt, a divine choice for your little angel!

SO DISSAPOINTED!
Size: Size 4 (104 Count), Color: Donut Grow Up + Cactus Cuties
I am a huge fan of honest diapers and products but i am very DISAPPOINTED in this companies policies. I got a bad batch of diapers, the tabs pulled off of more than 70% of the 104 diapers! I tried to do the right thing and contact the selling company, they sent me to to the manufacturer who eventually sent me back to amazon for a refund. However, since it took so long for me to get email responses from the providing compan and the manufacturer they only gave me a $9 refund from a $45 dollar purchase, which is absolutely garbage! I did everything they asked me to and got SCREWED because of it. I thought this company cared about its customers but they obviously dont. I have been buying honeat diapers for nearly 3 years now, but that changes today, i hope saving $30 was worth giving up a customer who bought diapers for 2 kids for 3 years! What a shame, I wish companies cared more about their customers than they do their bottom line, but that is clearly not the case. Well, with 2 more kids they lost out on at least $5k, I sure hope saving $30 was worth it to them.... What a shame..
