E-Bike D40 25 km/h 250W – 48V 40Ah Fatbike for Delivery & Daily Use

D40 E-Bike 25 km/h 250W – 48V 40Ah Fatbike for Delivery & Everyday Use
The D40 is a robustly equipped e-bike for riders who require exceptional range, comfort, and reliability in their daily lives. With its 250-watt rear-wheel motor, large 48V 40Ah battery, and a range of up to 160 km, this fatbike is particularly well-suited for delivery services, courier runs, daily commuting, and longer tours.

The combination of wide 20×4.0-inch puncture-resistant fatbike tires, hydraulic disc brakes with 203 mm rotors, front and rear suspension, and a sturdy aluminum frame makes the D40 a versatile e-bike for intensive daily use. Riders who cover many kilometers professionally will especially benefit from the high battery capacity and equipment designed for long working days.

48V 40Ah Battery – High Capacity for Long Distances
The D40 features a large 48V 40Ah lithium battery with a capacity of 1920 Wh. The high battery capacity enables a range of up to 160 km, making the e-bike especially attractive for long work days, delivery trips, and extended rides.

In delivery services in particular, the high battery capacity can reduce the need for frequent charging stops. The battery is removable and can be charged separately from the bike, for instance in an apartment, office, or at a suitable charging location.

An integrated 40A BMS helps protect the battery from overcharging and deep discharge. The battery is designed for more than 800 charge cycles and features IP64 protection against dust and splash water. Replacement batteries are available separately and can be obtained from a European warehouse.

The actual achievable range depends on various factors. These include, among others, rider weight, payload, assistance level, speed, gradients, road surface, tire pressure, outside temperature, and weather conditions.

250W Rear Motor with up to 80 Nm of Torque
The D40 is powered by a 48V 250W brushless gear hub motor on the rear wheel. With a torque of up to 80 Nm, the system assists the rider during starts, in frequent stop-and-go traffic, and on more demanding routes.

Motor assistance is provided up to a speed of 25 km/h. Combined with the large 48V 40Ah battery, this creates a drive system designed for endurance and intensive daily use.

Single-Speed Drivetrain – Simple and Low-Maintenance
The D40 uses a simplified single-speed drivetrain without a traditional gear shifter. Reduced mechanical complexity can help lower maintenance requirements, especially during intensive daily use.

The motor utilizes durable plastic-steel hybrid gears, designed for wear resistance and regular use. Especially for delivery riders with frequent stops and starts, the straightforward drivetrain offers a practical solution for daily operations.

Ideal for Delivery and Intensive Daily Use
The D40 was developed with riders in mind who use their e-bike not just occasionally, but regularly over long periods. The combination of large battery capacity, wide fatbike tires, hydraulic brakes, front and rear suspension, and high maximum load capacity makes the bike particularly attractive for delivery and courier services.

Even outside of professional use, the D40 is suitable for commuters, longer leisure rides, and riders seeking a comfortable, high-range e-bike.

20×4.0-Inch Puncture-Resistant Fatbike Tires
The wide 20×4.0-inch fatbike tires feature a reinforced, puncture-resistant construction designed for long daily rides. The large contact patch with the ground supports a stable and controlled ride on various road surfaces.

The tires are designed for high wear resistance and are suitable for city streets, wet roads, gravel, and uneven terrain. At the same time, the wide tire construction helps to dampen minor bumps.

Hydraulic Disc Brakes with 203 mm Rotors
For reliable stopping power, the D40 is equipped with hydraulic disc brakes on the front and rear. The large 203 mm rotors support powerful and controllable braking performance.

Especially during frequent stops in delivery operations, in dense city traffic, or when riding with additional payload, an easily modulated braking system is crucial. The brake system also includes 5.0T sintered brake pads as well as brake sensors for motor cut-off.

Front and Rear Suspension for Longer Rides
The D40 features an adjustable mechanical aluminum front suspension fork as well as a 350B mechanical rear shock absorber. The suspension helps to reduce shocks and vibrations caused by potholes, gravel paths, and uneven city streets.

Combined with the wide fatbike tires, this creates a comfort-oriented chassis that is particularly advantageous for longer daily rides.

3.8-Inch LCD Display with USB Port
The 3.8-inch LCD display clearly shows important information during the ride. This includes battery level, current speed, ride mode, and odometer reading.

The system offers five PAS assistance levels and also features a USB port for charging compatible devices. Essential functions such as lighting, turn signals, horn, power, and cruise control can be operated using the controls on the handlebar.

IP67 Protection for Critical Electrical Components
For regular use in changing weather conditions, critical electrical components of the D40 are built with IP67 protection. This includes the 48V 25A controller, K5304 display, electrical wiring, as well as water-protected quick-connectors and ports for the motor, battery, and lighting.

The controller is protected within the battery area, placing it in a position less exposed to direct splash water than if it were mounted underneath the frame.

Lighting with Turn Signals and Brake Light
The D40 features a lighting and signaling system powered directly by the 48V system. The front light unit combines low beam, daytime running light, horn, as well as left and right turn signals.

At the rear, there is a brake light as well as left and right turn signals. When braking, the rear brake light automatically becomes brighter. The integrated lighting is particularly practical for riders who regularly commute in the evening, in poor lighting conditions, or in urban traffic.

Robust Aluminum Frame with up to 200 kg Maximum Load
The frame of the D40 is made of a high-strength aluminum alloy and is designed for stability and daily use. The e-bike supports a maximum load of up to 200 kg, providing extra reserves for the rider, personal equipment, and delivery accessories.

The total weight of the bike, including the battery, is up to 48 kg. The aluminum construction is also designed to be resistant to rust and corrosion, making it suitable for regular outdoor use.
