Who it fits
Good fit for
You should consider this kit if you have a 26-inch rear wheel and want maximum speed. The 72V system and 5000W motor suit riders who prioritize acceleration over range. It fits those who enjoy customizing their ride through the programmable display. The waterproof connectors make it suitable for varied weather conditions. If you need a rear fork width of 150-155mm, this wheel fits directly. It is ideal for experienced builders who can handle high-power conversions.
Who should skip it
You should skip this option if your bike uses a different wheel size like 29-inch or 27.5-inch. The kit is only available in specific diameters. It is not for casual commuters who need quiet operation. The 5000W motor is loud and aggressive. If you require a 5T high-torque motor instead of the standard 3.5T high-speed version, you must contact the seller for customization. It does not include a battery. You must source a compatible 72V pack separately.
Verdict: This kit delivers serious power for the right frame. It suits builders seeking high speed and customization. Ensure your wheel size and fork width match before buying.
NB Power Kit Key Specs
Motor Power: 5000W
This motor delivers substantial torque for rapid acceleration and steep hill climbing. You will notice strong pulling power when starting from a stop or overtaking traffic. This power level suits riders seeking high-speed performance rather than casual cruising. Compare this to standard e-bikes that often cap at 750W or 1000W. Higher wattage means more energy consumption, so you must ensure your battery can handle the load without draining too quickly during long rides.
Battery Voltage: 72V
A 72-volt system provides higher electrical pressure than common 48V or 52V setups. This voltage allows the motor to spin faster and maintain power under heavy loads. You will experience better top speeds and improved efficiency on inclines. When shopping, check if your existing battery is compatible with this voltage. Using the correct voltage is critical for safety and performance. Higher voltage systems often require more robust wiring and controllers to handle the increased current flow safely.
Wheel Size: 26 Inch
This kit is designed for wheels with a 26-inch diameter. You must verify that your bicycle frame and forks accept this specific wheel size before purchasing. This size is common on older mountain bikes and some cruiser styles. If your bike uses 27.5-inch, 29-inch, or 700C wheels, this kit will not fit without major modifications. Always measure your current wheel or fork width to ensure compatibility. Incorrect wheel size selection will prevent installation and render the kit unusable for your specific bicycle.
Rear Fork Distance: 150-155mm
The motor hub requires a rear dropout spacing between 150 and 155 millimeters. You need to measure the inside width of your bike's rear forks to confirm this fit. This measurement is standard for many fat tire bikes and some mountain bikes. If your frame is narrower or wider, the motor will not install correctly. Check your bike manual or measure directly with calipers. Proper spacing ensures the wheel sits securely and the brakes align correctly with the rotor.
Controller: Sabvoton 100A
The system uses a Sabvoton controller rated for 100 amps. This component manages power flow from the battery to the motor. A 100A rating supports the high power output of the 5000W motor. You get reliable performance with programmable settings for speed and torque. This controller features waterproof connectors, which helps protect electronics from rain and mud. When comparing kits, check the controller brand and amperage rating to ensure it matches your motor's requirements for safe operation.
Design and Build Overview
According to the listing, this kit features a 3.5T high-speed QS 205 motor. The motor weight contributes to the total unit weight of 35.3 pounds. You should note that a 5T high-torque version is available if you contact the seller for customization. The system is built for a 26-inch wheel, though other sizes like 29-inch and 27.5-inch are offered as variations. The rear fork distance is specified as 150 to 155 millimeters. This narrow clearance limits compatibility to specific frame types. You must verify your bike’s rear dropouts match this dimension before purchase.
The electronics include a Sabvoton programmable 100A controller with a sine wave design. This component manages power delivery smoothly. All parts, including the controller, brakes, throttle, and display, use waterproof fast-release connectors. This design choice simplifies maintenance and protects connections from moisture. You can disconnect components easily for repairs or upgrades.
Control is handled by a TFT color LCD display. It offers five-level speed control, wheel size selection, password settings, and tracking for distance and time. The interface is fully programmable. This layout gives you precise control over performance parameters. The finish and build quality prioritize function over aesthetics. You get a robust, utilitarian setup designed for heavy use rather than casual commuting.
Setup and everyday use details

You operate the bike using the included TFT color LCD display. The screen allows you to adjust five speed levels. You can also select your wheel size for accurate speed readings. Password settings and distance tracking are available on the interface. The throttle provides speed control. You should ensure all connections are secure before riding. The waterproof features protect the electrical components from moisture. This setup supports high-speed performance. The 5000W motor delivers significant power. You will need a sturdy frame to handle the torque. The 3.5T motor version is standard. You can request a 5T high-torque custom version if needed. Daily use involves monitoring the display for distance and time. The system is designed for riders who prioritize speed and power over lightweight construction.
Before You Buy This Kit
This kit is a significant upgrade for your current bicycle. You will need a compatible 72V battery pack to power the system. The controller draws up to 100 amps, so your wiring must handle the load safely. Check your rear fork width carefully. The listing specifies a 150 to 155 millimeter spacing. If your frame is wider or narrower, the wheel will not fit. You should also verify that your brakes can stop the rapid acceleration this 5000W motor provides. Regular maintenance includes checking the waterproof connectors for corrosion. The TFT display allows you to adjust speed and wheel size settings, which helps fine-tune performance. This setup sits at the high end of electric bike kits. It suits riders who want maximum speed and are comfortable with technical installation. Casual commuters might find it too powerful. Ensure you have the tools and knowledge to install the rear wheel securely. This is not a plug-and-play solution for beginners.
Check before you buy
- Verify rear fork spacing is 150-155mm.
- Confirm you have a 72V battery.
- Ensure brakes handle high speed.
- Check wiring ampacity for 100A controller.
