HKM-305235 Folding Electric Bike · E-FAT-STEP

Precision engineering meets urban agility — a 48V 500W fat‑tire folding e‑bike designed for smooth commuting and off‑road exploration, delivering up to 50 miles per charge with hydraulic stopping power.

🔋 40–50 mi Range
🛑 Hydraulic Disc Brakes

Brushless Powertrain & Intelligent Pedal Assist

The 48V 500W brushless rear hub motor delivers consistent torque across varied gradients. With a top speed of 30–50 km/h (approx. 18.6–31 mph), the motor control unit modulates output seamlessly, whether you rely on the throttle or the responsive pedal‑assist sensor. The integrated 12.5Ah lithium battery uses high‑density cells to balance weight and endurance.

Sustained Torque Output

500W nominal power with peak efficiency tuned for both stop‑and‑go traffic and steady cruising. The brushless design reduces maintenance and extends motor life.

12.5Ah Lithium Battery

Samsung/LG-grade cells in a compact downtube pack. Full charge in 5–6 hours, delivering 40–50 miles (64–80 km) depending on assist level and terrain.

Lightweight Alloy Frame & One‑Step Folding

The 20‑inch frame is crafted from 6061 aluminum alloy, achieving a optimal strength‑to‑weight ratio. The patented step‑through design (E‑FAT‑STEP) allows easy mounting, while the centralized hinge lets you fold the bike in under 10 seconds for storage in compact spaces — car trunks, closets, or RV compartments.

Aluminum 6061

Corrosion‑resistant, lightweight structure that maintains rigidity during high‑speed cornering.

Folding Hinge Lock

Industrial‑grade latch with safety pin; folds to 35 x 25 x 17 inches (89 x 64 x 43 cm) approx.

Step‑Through Geometry

Low standover height accommodates riders from 5'1" to 6'3" (155–190 cm) comfortably.

Shimano 7‑Speed Drivetrain & KENDA Fat Tires

Equipped with a Shimano Tourney 7‑speed rear derailleur and a responsive thumb shifter, the HKM‑305235 adapts instantly to changing inclines. The 20" x 4.0" KENDA/CHAOYANG sport tires provide exceptional floatation on sand, snow, and gravel, while maintaining low rolling resistance on pavement. Black alloy double‑wall rims add durability without excess weight.

Gear range Shimano 7‑speed, 14–28T freewheel
Rims 20‑inch black alloy, double‑wall

Hydraulic Disc Brakes with Motor Cutoff

Eunorau hydraulic disc levers actuate front and rear 160mm rotors, delivering progressive stopping power even in wet conditions. The integrated motor cutoff switch instantly disengages drive power when braking, enhancing safety during emergency stops. The super‑bright LED rear light with wide‑angle lens ensures visibility from behind at night.

Dual Piston Calipers

Mineral oil hydraulic system with minimal fade, tested for consistent lever feel across long descents.

Motor Cutoff Sensor

Brake lever switch signals the controller to halt motor output in milliseconds, adding a critical safety layer.

Rider‑Focused Experience

From the ergonomic saddle to the adjustable stem, every touchpoint is refined for long‑distance comfort. The wide 4‑inch tires act as natural suspension, absorbing road vibrations without the complexity of heavy shocks. Whether you’re weaving through city traffic or cruising coastal trails, the bike’s geometry keeps you stable and confident.

Intuitive Controls

Thumb throttle and assist level selector placed within natural reach. LCD display shows speed, distance, and battery status clearly.

Universal Fit

Adjustable seatpost and handlebar accommodate a wide range of rider heights, ensuring an ergonomic posture.

Frequently Asked Questions

What is the real‑world range on throttle only?

On flat terrain with minimal wind, throttle‑only operation typically yields 25–32 miles (40–51 km). Using pedal assist extends range significantly, up to 50 miles.

How does the folding mechanism secure during transport?

The main hinge incorporates a stainless steel locking pin and a secondary safety clamp. Once folded, the bike remains compact and stable for lifting into vehicles.

Can the battery be charged on or off the bike?

Yes, the 12.5Ah pack is removable and can be charged indoors or while mounted on the frame. A full charge takes approximately 5–6 hours.

What maintenance do hydraulic brakes require?

Mineral oil systems rarely need bleeding. Inspect pads every 300 miles (480 km) and keep rotors clean for optimal performance.

Durable, Fun, Best Toy Ever for My Spoiled Rotten Rottweiler
This is one of the best toys EVER for our 107 lb male Rottweiler. We have had the Med/Large size for over a year and it has remained Sam’s favorite toy and proven extremely durable. We play fetch and toss/catch with it in the yard and he throws it in the air, pounces on it and makes it squeak like prey. BTW some reviews say their toys don’t squeak; I am guessing those people have the wrong kind of dog for this toy. I can’t make it squeak with my hands, but my Rottie’s powerful jaws have no problem. It’s ideal as a toy for a big, powerful dog when all other toys have fallen apart. I just got Sam the Large/XL size and he was absolutely delighted with it!

Not Boerboel proof
I have a terrible time finding toys for my 10 month old Boerboel. Either she ignores it or tears it up immediately. She likes this toy (jumbo size) and actually chewed on it for 20 min. Bad side is she chewed a hole. It lasted longer than any of the other fairly chewy toys I've tried. She doesn't like the hard chews.

Favorite Toy
Size: Medium/Large, Product Packaging: Standard Packaging
My dog is a 3.5 yr old mix and this toy has been her favorite toy by far for three years. She likes it as a squeak toy, loves it as a tug toy and can't live without it as fetch toy. I roll it on its edge outside and she chases it - sometimes it take cool bounces or swerves and sometimes its just rolls straight and fast and whatever it does she can't get enough of it. She demands we play fetch with it at least three times a day. She's not a great releaser of fetch toys so there's plenty of tugging play involved too. We've had three of these over three years, but she's 75 pounds of muscle and it gets a work out every day so it's a really tough toy. All dogs are different, so I don't know what your dog will think, but it's been a fantastic toy for our girl.

So Bad
Size: Medium/Large, Product Packaging: Standard Packaging, Size: Medium/Large, Product Packaging: Standard Packaging
Had high hopes for this toy as Kong is fantastic with aggressive chewers as or Lulu is. This toy didn't last 30 minutes before she was able to tear it apart. The rubber and plastic are not of the same quality on nearly all there other toys she has. Have found better toys for half the cost. Kong needs to do better.
