Performance Review

The NIU BQI-C3 Pro is a Class 3 electric bike with a top speed of 28mph. Its stylish and sleek step-thru design makes it visually appealing. One of the standout features is th single-belt drive and also the dual battery setup, which significantly extends the bike’s range, providing up to 90 miles of travel when both batteries are used at a speed of 9mph on pedal assist 1. The bike’s weight is manageable at 70 lbs, making it relatively easy to handle.

When it comes to ride quality, the NIU BQI-C3 Pro delivers a nice and stable ride. The nominal power of 500W and peak power of 750W provide sufficient acceleration and performance.

The 27.5×2.4″ air-filled pneumatic tires contribute to a smooth and comfortable ride over various terrains. However, one area of improvement is the bike’s performance on inclines. While the pedal assists handles inclines slowly but with ease, the throttle did not perform as well in these situations.

Top Speed

The NIU BQI-C3 Pro impressed me with its top speed, reaching a quite nice 28 mph on the pedal assist. The throttle had a maximum speed of 20 mph. The bike falls into the class 3 designation.



The NIU BQI-C3 Pro’s acceleration felt smooth. Whether I used any of the pedal assists, the gradual increase in speed felt natural, and it gave me a sense of control, as if I was seamlessly integrating with the bike’s power.

Hill Climb

The NIU BQI-C3 Pro’s performance on inclines was somewhat mixed. I managed a 12% grade incline slowly. When relying solely on the throttle, it didn’t perform well on steep inclines while the pedal assist performed much better and managed the inclines more effectively.


The NIU BQI-C3 Pro has an impressive range thanks to its dual battery. With a total battery capacity of 48V 10Ah each, providing a combined power of 920Wh, the bike offers good endurance for long rides.

I achieved an impressive range of 90 miles using the 1st pedal assist mode only, maintaining a slow and steady speed of 9mph. I tested the range separately for both the throttle and pedal assist modes. The throttle provided a respectable range of 50 miles, while the pedal assist mode outperformed with a range of 90 miles. I was able to achieve 45 miles on PAS 1 using a single battery, and this was achieved on a flat road at a speed of 9mph with a weight of 165 lbs.

Ride Quality

The NIU BQI-C3 Pro provided a smooth and stable ride, which I like. The steering felt nimble and agile, making it easy to navigate through various terrains. I like the power delivery as both the pedal assist and thumb throttle was responsive without any noticeable lag.

The weight distribution on the bike felt well-balanced, and it handled the ride with good stability, even when carrying loads of up to 287 lbs.

The bike’s nominal 500W motor and powerful 750W peak power provided ample assistance during my rides. The three levels of pedal assist further enhanced the overall riding experience, allowing me to choose the level of assistance that best suited my needs and the terrain I was riding on.



The NIU BQI-C3 Pro is equipped with mechanical disc brakes made by NIU and a 180mm rotor, which I like over the typical 160mm size and provides better braking performance. The bike also has motor/power cut-off levers, ensuring quick and efficient stopping power.

While the mechanical disc brake is okay, I personally prefer hydraulic brakes, especially for a class 3 bike like this one.



The NIU BQI-C3 Pro has no suspension at all, which was a bit disappointing as it affects the overall ride comfort, especially on rough or uneven terrain.

NIU BQI-C3 Pro Features


The NIU BQI-C3 Pro features a well-built frame with a two-toned aluminum body, which gives it a sleek and modern appearance. The bike’s weight of 70 lbs is manageable and does not feel overly heavy during rides. You’ll also have a bike load rating of 287 lbs.

The rear rack has a load rating of up to 30kg and is practical and convenient. Although the bike is not foldable, it’s not an issue for me as the step-thru design already provides excellent accessibility and ease of use.


The NIU BQI-C3 Pro is available at a price of $1,999 both on the website and on Amazon. Currently, it is on sale, offering a discounted price from its regular cost of $2,199.


The NIU BQI-C3 Pro’s portability has a dimension measuring 74″ x 40″ x 41″. Its low 12.6-inch stand-over height makes it accessible and suitable for riders with heights ranging from 5’2″ to 6’6″. 



The NIU BQI-C3 Pro’s styling is impressive and sleek. I particularly like its step-thru design, which not only looks elegant but also provides easy access and a comfortable riding position. The two-toned color adds to the overall aesthetics, giving the bike a modern and sophisticated look.

The bike features internal wiring, contributing to a clean and clutter-free appearance. The external wiring is neatly done, ensuring a tidy and organized look throughout the bike.


Battery Pack

The NIU BQI-C3 Pro’s battery pack is a convenient and user-friendly feature. It is removable, making it easy to charge the battery separately from the bike. The lockable design also adds an extra layer of security.

The charging time for both batteries is up to 10 hours, which is okay considering it’s dual batteries.


The NIU BQI-C3 Pro comes equipped with a colored TFT display, measuring 3.5 inches. The display showcases a wealth of information and features, which I find quite useful during my rides. However, I noticed that it’s not as visible under bright sunlight. The display automatically dims when the headlight is turned on, ensuring better visibility during nighttime rides.

Despite the slight visibility issue in daylight, I appreciate the abundance of information presented on the colored display. It provides essential details such as speed, battery level, pedal assist level, and more, allowing me to stay informed about my ride at a glance.



The NIU BQI-C3 Pro is equipped with 27.5″X2.4″ air-filled pneumatic tires specifically designed for street use. These tires provide a smooth and comfortable ride on pavements and urban roads, making it an ideal choice for daily commuting and city rides.

The tires are puncture-resistant, but I do not recommend them for mid-terrain or off-road use.



The NIU BQI-C3 Pro is equipped with impressive lights that enhance both visibility and style. The daytime Halo-style headlight not only provides excellent illumination for riding during the day but also adds a touch of premium elegance to the bike’s overall design. The integrated brake light is a valuable safety addition also.



The NIU BQI-C3 Pro is not your average IP2 bike. The battery has an IP67 rating, ensuring it is protected against dust and can withstand immersion in up to 1 meter of water for 30 minutes. The motor, on the other hand, has an IP65 rating, indicating strong resistance to dust and protection against water jets from any direction.

The overall bike has an IP45 rating, meaning it offers some level of protection against dust and water splashes, making it suitable for light rainy conditions.


The NIU BQI-C3 Pro comes with a 2-year warranty and a 14-day return upon receiving the item with defects or minor scratches.

Additional Accessory

The NIU BQI-C3 Pro comes with practical accessories that add to its overall functionality and convenience. One notable accessory is the built-in rear rack, another useful feature is the dual chord for the same charging on both batteries allowing me to charge both batteries at the same time! Cool right? There is also an inclusion of the tool kit whenever you have minor parts that needs to tighten screws.

I was really impressed with the NIU BQI-C3 Pro’s stylish and neat design, which gives it a premium look suitable for daily city commuting. The single-belt drive is a standout feature, offering exceptional durability and minimal maintenance, a feature rarely seen in regular bikes. Moreover, the dual chord for simultaneous charging of both batteries adds convenience to my rides.

However, there are areas that could be improved, such as the thumb throttle, which feels flimsy and might not last long, and I would appreciate the inclusion of hydraulic brakes for better braking performance, especially considering the bike’s Class 3 designation.

One significant drawback is the absence of any suspension, which affects the bike’s overall comfort, especially on rough terrains.
