The YIBYKOU Electric Bike (2025) stands in a league of its own — an ultra-powerful, dual-motor fat-tire e-bike engineered for riders who demand thrilling acceleration, extreme torque, and all-terrain freedom. Delivering up to 5000 W of peak combined power, a 52 V 32 Ah removable battery, and a top speed of 40–45 MPH, it’s one of the fastest and most capable electric mountain bikes available today.
Built for adventurers, off-roaders, and serious commuters, the YIBYKOU redefines what an electric bike can do — with brute force, refined control, and endurance that rivals small electric motorcycles.
- Motor & Battery: The powerful 672W rear hub motor with a 499.2Wh high-capacity BAFANG battery, which covers a range of up to 24-59 miles per charge
- Comfort and Ease of Use: This electric bike for adults is designed with a user-friendly step-through frame and a comfortable seat. Choose throttle for effortless cruising or one of three pedal-assist levels for easy riding
Design & Build Quality
The YIBYKOU has an unmistakable presence: bold, heavy-duty, and purpose-built. The 6061 aluminum alloy frame is reinforced to handle the torque of dual motors while maintaining structural rigidity. Despite its aggressive profile, the welds are clean and the geometry well balanced for high-speed stability.
The integrated battery housing keeps weight low and centered for improved control, and the matte black powder-coat finish resists scratches and corrosion.
Available in both 24-inch and 26-inch tire configurations, the bike adapts to rider height and terrain preference. The fat-tire setup (4.0–4.5 in width) delivers exceptional grip on dirt, snow, or pavement.
The overall design communicates raw capability while remaining surprisingly ergonomic — wide handlebars, an adjustable saddle, and full-suspension comfort make it as functional as it is fierce.
Dual-Motor Powertrain – 5000 W Peak, 45 MPH Top Speed
At the heart of the YIBYKOU lies its defining feature — dual brushless hub motors, each producing 2500 W peak. Combined, they unleash up to 5000 W of instantaneous power and a staggering 190 Nm of torque.
Switchable drive modes let you tailor the experience:
- Front Motor Only: Improved traction control in slippery conditions.
- Rear Motor Only: Efficient cruising for longer range.
- Dual Motor Mode: Maximum acceleration and climbing ability.
Expect true motorcycle-level performance:
- Top Speed: 40–45 MPH
- 0–30 MPH Acceleration: ≈ 5 seconds
- Hill Climb: 35°+ inclines effortlessly
Power delivery feels instantaneous yet smooth, thanks to an intelligent dual-controller system that balances output between motors.
Battery & Range – 52 V 32 Ah (1664 Wh) Power Pack
Feeding the beast is a 52 V 32 Ah lithium-ion battery, offering one of the largest capacities in its class.
- Pedal Assist Range: Up to 100 miles
- Throttle-Only Range: ≈ 60 miles
- Charge Time: ≈ 8–10 hours
The removable battery locks securely into the frame and can be charged on or off the bike. A built-in Smart BMS (Battery Management System) protects against overcharge, over-current, and thermal overload.
For long-distance explorers or daily riders who hate recharging, this pack delivers genuine endurance — enough for multi-day rides between charges.
Transmission & Riding Modes
The YIBYKOU features a Shimano 7-speed drivetrain and three electric assist modes, providing total control:
- Eco Mode: Extended range for long cruises.
- Normal Mode: Balanced power and efficiency.
- Sport Mode: Full dual-motor torque for maximum thrill.
You can toggle seamlessly between PAS (pedal assist) and throttle-only riding depending on your terrain or energy level.
The drivetrain shifts smoothly, and with the immense torque available, you’ll rarely need to drop below mid-range gears.
Suspension & Ride Comfort
Given its speed potential, the YIBYKOU integrates a full-suspension system to maintain comfort and control:
- Front Fork: Adjustable hydraulic suspension with lockout.
- Rear Shock: Heavy-duty coil spring absorber for trail impact resistance.
This setup, combined with fat tires, eats up bumps, gravel, potholes, and off-road obstacles with ease. The ride feels planted and confident even on rough backroads or loose dirt.
The wide ergonomic saddle and upright riding posture make long rides surprisingly comfortable despite the bike’s aggressive capabilities.
Braking System – Hydraulic Disc Control
To match its immense speed and power, the YIBYKOU employs hydraulic disc brakes with 180 mm rotors front and rear.
Stopping is immediate, progressive, and fade-free — critical when decelerating from 40 MPH. The motor cut-off sensors instantly disable throttle input during braking for added safety.
Braking feel is confident even under full load or steep downhill descents.
Display & Controls
A large full-color LCD display dominates the cockpit, providing real-time metrics:
- Speed / Average / Max Speed
- Dual-motor status and power distribution
- Battery percentage and voltage
- Trip distance / Odometer
- PAS level and mode indicator
Backlit for night riding and fully waterproof (IP65), it’s easy to read in sunlight. The control pad beside the left grip allows effortless toggling between PAS levels and motor modes while riding.
Lighting & Safety Features
Night visibility is excellent thanks to a high-intensity LED headlight, rear brake light, and reflective tire strips. The electrical system is UL-compliant, ensuring safe current management and temperature protection.
Optional accessories include turn-signal integration and horn functionality — features often reserved for e-mopeds.
