Who it fits
Good fit for
You should consider this kit if you have a rigid frame with 135mm rear dropouts and want maximum speed. It suits riders who already own a high-voltage battery pack, likely in the 72V range, to fully utilize the 3000W motor. The inclusion of a 100km/h top speed claim makes it ideal for experienced riders comfortable with high-velocity travel. You will need a robust fork capable of handling the torque and a compatible wheel size, such as the 19-inch option shown.
Who should skip it
Skip this option if you need a quiet, efficient commuter bike. The 3000W motor and high voltage range are not suited for subtle pedal assistance or long-range efficiency. If your frame uses 100mm or 130mm dropouts, this 135mm kit will not fit without modification. You should also avoid this if you prefer a simple, low-maintenance setup, as the high-power components require careful installation and maintenance. It is not designed for casual recreational riding.
Verdict: This kit delivers serious power for riders with compatible 135mm frames and high-voltage batteries. It is a specialized tool for speed, not everyday efficiency.
NB Power Key Specs Explained
Motor Power: 3000W
This rating indicates the continuous power output of the hub motor. A 3000W motor provides strong acceleration and can handle steep inclines with ease. You will notice significant torque when starting from a stop or climbing hills. This level of power suits riders who want to replace a standard bicycle with a high-performance electric vehicle. Compare this to standard e-bikes that often use 250W or 500W motors for lower speeds and legal compliance.
Top Speed: 100km/h
The listing claims a maximum velocity of 100 kilometers per hour. This speed is extremely high for a bicycle conversion kit and typically exceeds legal limits for road use in many regions. You must check local laws before riding at this pace. High speeds require robust braking systems and stable tires. This spec targets experienced riders looking for maximum performance rather than casual commuting. Always verify if this speed is achievable with your specific battery and tire setup.
Battery Voltage: 48V-72V
This kit accepts a wide range of battery voltages, from 48V to 72V. Higher voltage generally increases power output and top speed. You can choose a battery based on your desired performance level. A 72V system will likely provide more power than a 48V setup. Ensure your chosen battery fits your frame and matches the controller requirements. This flexibility allows you to upgrade your power system later without changing the entire kit.
Wheel Size: 19"
The motor is designed for a 19-inch wheel rim. This is an uncommon size for standard bicycles, which typically use 26-inch, 27.5-inch, or 700C wheels. You must ensure your bike frame has 135mm dropouts to fit the rear fork. This specific wheel size limits compatibility with most standard bikes. Check your current rim diameter carefully before purchasing. If you do not have a 19-inch rim, you may need to source one separately or choose a different kit size.
Design and Build Overview
According to the listing, this NB Power kit uses a 19-inch motor rim as its standard configuration. You can also select other wheel sizes including 27.5-inch, 700C, 26-inch MTX, or 29-inch rear options. This flexibility allows you to match the conversion to your existing frame geometry. The motor is designed specifically for rear forks with a 135mm dropout spacing. You must verify that your bicycle frame meets this requirement before installation. A mismatch in dropout width will prevent proper mounting.
The system includes a sine wave controller rated at 80A. It comes with a dedicated controller bag for protection. This layout keeps the electronics secure while managing heat dissipation. You will also receive a single-speed freewheel and an alarm lock. These components simplify the mechanical setup by reducing the number of parts you need to install. The alarm feature adds a layer of security for your bike when parked.
Control is handled by a TFT UKC1 color display. This interface provides clear visual feedback for your ride parameters. The controller supports a dual mode that addresses Error 07 issues. This design choice aims to improve reliability during operation. The overall build focuses on high-output performance for rear-wheel drive conversions. You should ensure your frame can handle the physical dimensions of the 19-inch hub. The finish and materials are chosen to support the 3000W power rating.
Setup And Daily Use Guide
Setting up this NB Power conversion kit requires matching the physical dimensions of your bike frame. The standard configuration features a 135mm rear dropout spacing. You must ensure your frame accommodates this width before installation. The kit includes a 19-inch motor rim, though other sizes like 27.5-inch, 700C, 26-inch MTX, or 29-inch are available as variations. Selecting the correct wheel size is critical for proper fitment and alignment.
Electrical setup involves connecting the motor to a battery within the 48V to 72V range. The system utilizes a sine wave controller rated at 80A. This controller is housed in a protective bag, which helps shield the electronics from road debris and moisture. The dual-mode controller design is specified to help resolve Error 07, a common fault code in hub motor systems. This feature may simplify troubleshooting during the initial setup phase.
For daily use, the TFT UKC1 color display provides essential ride data. You can monitor speed and power levels through this interface. The system operates as a single-speed setup, meaning you rely on your bicycle’s existing gears for traction control. An alarm lock is included to deter theft when the bike is parked. The 3000W motor power rating suggests strong acceleration and high-speed potential, reaching up to 100km/h. This level of performance requires careful handling and adherence to local traffic laws. The combination of a robust controller and clear display aims to make the conversion process straightforward and the riding experience responsive.
Check Compatibility Before You Buy
Before purchasing this NB Power 135mm dropouts e-Bike kit, you must verify your frame compatibility. The kit requires a 135mm rear dropout spacing. If your bike uses a different width, this conversion will not fit. You also need to confirm your battery voltage matches the 48V to 72V input range. The system includes a 19-inch motor rim, but you can select other sizes like 27.5-inch or 29-inch. Ensure your chosen wheel size aligns with your current tires and brakes. The 3000W motor draws significant power, so your existing electrical system must handle the load. You will need a compatible controller and display, which are included. Regular maintenance is essential for high-output components. Check the controller bag and wiring connections periodically. This kit suits riders wanting extreme speed, reaching up to 100km/h. It differs from standard e-bikes by offering raw power rather than integrated convenience. You are responsible for installation and legal compliance. This option is best for experienced builders who can manage complex upgrades safely.
Check before you buy
- Verify your frame has 135mm rear dropouts.
- Confirm battery voltage is between 48V and 72V.
- Ensure your brake system handles high speeds.
- Check local laws for 3000W motor use.
