Today, I’ll be discussing F-Wheel’s latest electric bike, the DYU D3. It combines features from its predecessors, the DYU D1 and D2, while introducing improvements, particularly in terms of driving comfort. What impressed me the most is its impressive range. Is it worth it?

IN SHORT, WHAT’S THE DYU D3 WORTH?
✅ The pros
- Sleek and modern design
- Comfortable riding experience
- Impressive range (up to 24 miles)
- Maximum speed of 15 mph
- Lightweight (40 lbs)
- Convenient folding mechanism for portability
❌ The cons

This latest iteration of the renowned DYU folding bike integrates a range of technologies and offers improved autonomy (25 miles). Constructed from lightweight yet durable aluminum alloy and equipped with dual disc brakes, it’s well-suited for urban or rural rides. With a weight of 40 lbs, it’s convenient to use as a regular bike when the battery runs out.
Why Choose the DYU D3?
The DYU D3 is offered in 3 colors: red, black, and white—simple yet stylish choices. Personally, I opted for black and I’m thoroughly pleased! I believe the black color adds a touch of “luxury” to the DYU D3 F-Wheel, complementing its minimalist design.
Its small wheels set it apart from traditional bikes, adding a unique elegance. The designer aimed to emulate the appearance of a dolphin, and in my opinion, they succeeded admirably.
The F-Wheel DYU D3 is a foldable electric bike, ensuring easy transportability wherever you go. It’s slim and lightweight, weighing just 40 lbs, making it effortless to carry. It fits snugly into a car trunk for added convenience.
3 Driving Modes Tailored to Your Needs
The DYU D3 bike offers three driving modes to suit your preferences:
- Pure Electric Mode: Allows you to ride without pedaling, effectively transforming the bike into an electric scooter. I particularly appreciate this mode as it’s not commonly found on electric bikes. After a long day of work, there’s nothing like cruising home without pedaling! However, it may reduce range, offering approximately 18 miles of range in this mode.
- Assisted Mode: Provides assistance to the rider, enhancing the bike’s range up to 25 miles. This mode is easily activated via the LCD screen on the handlebars.
- Unassisted Mode: Requires pedaling to propel the bike forward, similar to a traditional bike. Ideal for those seeking a workout.
According to the manufacturer, the bike boasts a range of up to 25 miles. However, after conducting several tests, I’ve observed an average range of 22 miles (I weigh 165 lbs). It’s important to note that the maximum weight capacity is 265 lbs.
Compact Wheels and Enhanced Braking
The DYU D3 tires are 14 inches in size. Initially, I was a bit surprised by the size, but ultimately I had no concerns, given the manufacturer’s focus on quality manufacturing. The tires are crafted from highly durable rubber, ensuring they resist wear and degradation over time.
The tires are designed to enhance the bike’s handling in wet conditions. Additionally, the bike complies with IP65 standards, ensuring water resistance.
The bike is equipped with front and rear disc brakes, providing a braking distance of 5.9 feet in dry conditions and 8.2 feet in wet conditions. This short braking distance enhances the safety features of this electric bike.
Comfort and Shock Absorption
The bike’s saddle is comfortable and adjustable, spanning 11.8 inches to prevent excessive knee bending. Equipped with springs, it ensures a smooth ride and absorbs shocks effectively. After covering several miles on this bike, I haven’t experienced any significant shocks, except on very rough roads.
Battery and Motor
The DYU D3 electric bike is equipped with a lithium battery (the best!), available in 6Ah/10Ah capacity variants, offering better longevity and capacity compared to average batteries. It takes approximately 4 hours to recharge from 0 to 100%, which may not fully accommodate its 25-mile range.
The motor is a 36V 250W unit, capable of achieving speeds of up to 15.5 mph with pedal assistance, compliant with European pedelec legislation. The motor provides ample torque, effortlessly tackling inclines.
The DYU D3 features a mobile app that connects via Bluetooth, allowing users to adjust speed settings and access real-time bike information. Additionally, it enables remote bike locking with password protection, a feature I particularly appreciate.
The on-board computer displays the battery level using bars (there are 4 bars). It also activates the bike’s lights, one at the front and one at the rear. The front light is very bright, and I was pleasantly surprised by its range. The rear light flashes, ensuring you are highly visible in the dark.
The computer also allows you to select from different speed modes: eco, medium, and fast. This is a common feature found on most electric bikes, enabling you to adjust your bike’s speed.
Conclusion
The mini e-bike DYU D3 pleasantly surprised me—it’s far from being a toy but rather a reliable mode of transportation, even for long distances. Despite its compact size, comfort is well-considered, with adjustable features to suit different rider morphologies. I highly recommend it for everyday city use.
