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.

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.

Incredibly hydrating but unbearable scent.
Size: 1.3 Ounce (Pack of 1)
I love all Avène skin barrier creams, recovery lotions and i just purchased this "Hydrance" cream. Texture is nice, it's unbelievably hydrating but the scent is overwhelming. It caused me a headache. So I decided to return it. Then I thought I'll give it another try and Oh my.... For the love of God, remove that awful scent. The reason I love Avène product is because theyre unscented, except this one I guess :/

wheels are perfect
Size: Large, Color: Black
Really happy with this umbrella base so far. It feels sturdy and well-made, especially once filled—it definitely has the weight to keep my umbrella in place, even on windy days. The wheels are a huge plus. I can move it around the patio without struggling, which makes adjusting for shade super easy. The square design also looks clean and doesn’t take up too much space. Setup was simple, and it fits my umbrella perfectly. Overall, it does exactly what I needed—strong, stable, and easy to move. Great buy.

Easy rolling base
Size: Large, Color: Black
I purchased the umbrella base to enabling the ability to hold our umbrella and easy maneuver the umbrella on a paver patio. The base supported the umbrella and rolled sufficiently on the paver surface. However I did have an issue when readying the base for storage that the plastic umbrella pole support caused a black staining liquid on the pavers when it spilled on the patio
