Customer Ratings & Reviews

I am not an avid cyclist but bought a bike during the pandemic to help with the cabin fever. It is a healthy activity to do but I would always return drained depending on how far my trip was. My NIU BQI-C3 PRO Electric Bike is a dream come true for casual cyclists like me and folks who may otherwise prefer to cycle than drive. At about 70lbs, the NIU BQI-C3 PRO is heavy and two-person handling is highly recommended. It very well packaged with tons of Styrofoam and polyethylene foam. Overall, it arrived unblemished. Contents: • NIU BQI-C3 PRO Electric Bike • Manual • Tool kit: 2 open-end wrenches, 3 Allen key wrenches and a Philips screwdriver • Two keys • Charger with adapter for dual charging • User manual NIU has a YouTube video on the assembly. I would estimate the bike is about 85 percent assembled upon receipt. While the video is definitely helpful, I found some tricks (or efficiencies) as I worked on the assembly alone. I basically removed the wooden block from the from, collapsed the cardboard at the end of the base box and was able to install the front tire. I then rolled the bike out, with all the zip ties removed of course. I also loosened the headlight screws to be able to access all four screws for securing the handlebar. I may be missing something but there appeared to be no other way to get them fastened otherwise. The NIU BQI-C3 PRO is sturdy and appears well built. As one of its strong selling points, it ships with two 460Wh rated batteries that blend seamlessly into the frame. You do receive two identical keys for their release. The batteries can be charged while on the bike or independently outside. They even have power level indicators that tell the approximate level at the push of a button and blink to indicate charging. The bike can be operated with either one or both batteries. They are also swappable. The included charger ships with an adapter that makes dual charging a possibility. Should one be more depleted than the other, it is given priority until both batteries are at similar levels beyond which they charge uniformly. The two charging jacks have covers to protect the ports which may appear daunting, initially. I have discovered once the hole on the cover is aligned with the pin in the port, the covers snap on without fuss. On the dashboard, the batteries are represented independently: the rear battery (along the seat post) is indicated on the right while the front battery is on the left when looking at the dashboard. Renowned for their scooters, it is comforting to know that NIU have several redundancies built into their battery technology for safety. The stated five-hour charge time is for a single battery though so there was some anxiety as I waited for my first ride. Should there be a sale on the batteries, I may get another. As with all things, the durations expressed by the manufacturer may not be attained in real world use due to a myriad of differences. In my experience, the fun and joy to be had far outweigh trying to go the distance; there is a reason some prefer sports cars over regular fuel-efficient sedans. The dashboard provides a lot of information: odometer, speed, trip distance, trip time, riding time, average speed, max speed, cadence, range to empty, calories burnt, assist level, headlight indicator and a power ring (fills up when you are at the peak power for the selected assist level.) With time, I have become very comfortable reading the dashboard and interoperating the displayed information. There are submenus to change the units of measurement (metric to imperial), level of screen brightness (5 levels or auto) and duration for auto shutoff. Tucked underneath the dashboard is a USB Type-A port that can charge your phone with the appropriate cable. It is not the fastest, but you will be able to make that call if you are stranded but still have some juice in your bike. This is my first electric bike and it may have set a very high bar for me. The aluminum alloy frame is solid the bike has not creaked so far. Controls are easy to use, and the handlebars offer comfortable support when riding. The lack of any suspension, however, implies that you will feel every jolt when riding. Thankfully, the seat is very comfortable for what it’s worth. The tires are 27.5 x 2.4 Chao Yang branded with 1.5mm of Kevlar for additional durability. At 70 pounds, this bike may not be the easiest to drag along with a flat. Speaking of weight, there is a pedestrian mode that propels the bike at about 1 mph when engaged. I can see the convenience when needing to go walk the bike up an incline. The rear hub 500-Watt motor has specifications to reach 28mph. In operation, it is relatively quiet. It is a single speed setup with no derailleurs and a carbon drive belt instead of a traditional chain. The good news is that carbon drives require minimal service, are cleaner and quieter compared to their chain link counterparts. Durability is also exceptional with service life around tens of thousands of miles. There are three assist levels that could be used as “gears” when riding. Level 1 will help you reach a maximum speed of about 14 mph beyond which pedaling becomes pointless. For assist level 2, pedaling ceases effectiveness at around 22 mph. Level 3 will get you to around 26 mph and beyond! The throttle can only accelerate to 20 mph regardless of the assist level selected. This means should you select assist level 3, the bike will max out at 20 mph. To attain speeds beyond 20 mph, you will need to pedal. Operating the NIU BQI-C3 PRO is a little different compared to a traditional bike. I am sure everyone remembers their first bike. The general rule was the faster you pedaled, the faster you went. The logic with the NIU BQI-C3 PRO is that the slower you pedal, the faster you go. It is a bit counterintuitive, but it basically enables you to gracefully fly at 25mph with a cadence of about 50rpm. It was an “aha” moment for me and immensely changed the riding experience. As you gently pedal, the motor kicks in and does the rest. Go slow to go fast! The beauty is that this bike allowed me to keep up with (and overtake when I felt like it) professional cyclists on my trail who would constantly lap me on my previous manual bike! The mechanical disc brakes are quiet and very capable of stopping the bike, given its speed potential. The maximum recommended weight is a 287-pound rider who is also over the age of sixteen. The taillight is also brake actuated for extra safety. A cool thing to note is that when the light feature is engaged, the taillight can convey braking just like a car does with varying the brightness. The NIU BQI-C3 PRO has a daytime running light in its headlight assembly. It is a bright halo and illuminates as soon as the bike is turned on. For night, the aforementioned “light feature” automatically reduces the brightness of the dashboard and illuminates a very bright bulb at the center of the headlight assembly. Riding at dusk or even night riding can thus be conducted with a high confidence of safety. This is all provided along with the typical reflectors for the front, back, wheels and pedals. The kickstand is sturdy and very necessary for that fact due to the weight of the bike and the step through frame which makes attempting to straddle frame between your legs impossible. The bell gets attention and is easy (along with satisfying) to operate. As wonderful as the NIU BQI-C3 PRO is, I have a few items that I hope future iterations can incorporate. A clock would be a nice feature that would help a rider figure out the time without deferring to their watch. If you ride with a smartphone mounted, this may not be a big deal. In line with the previous item is the request for retention of the average and maximum speeds for the previous ride. Unfortunately, this data is refreshed with every shutdown. An app for the bike on a connected device (i.e., smartphone, tablet etc.) would be a very helpful enhancement, in my opinion. Through Bluetooth, perhaps, the rider would be able to download ride and bike data (i.e., battery discharge graphs, charge cycles etc.) Finally, the NIU BQI-C3 PRO electric bike appears to have all the bell(s) and whistles. It is a well thought out effort that I hope to enjoy for years to come. With a water resistance IP 45 rating and other thoughtful features like the bike rack, the commuting public was very much taken into account, in my opinion. The two-year warranty on the critical components is very generous as other manufacturers leave you with the typical one year. While I hope the next iteration could improve on a very good initial effort, it gets a solid recommendation in my books.

Having owned a Polestar 2 electric vehicle for a period of time and re-engaging with the love of driving; instant torque, insane acceleration, and environmental benefits, my expectations are unreasonably high for an electrified bike. TL;DR it succeeded re-engaging my love of bike riding after decades from the hobby. I was out of town when the box was delivered on front porch, told my wife just carry to the garage. She sent a pic and it was much larger than i expected. She felt the weight and as the box recommends, this is a two person job, both in moving the box, as well as assembly. The bike was carefully packed, all body frame surfaces were wire tied, all surface paint nicely wrapped in soft styrofoam. The base of the package contains a large block that the back tire (pre-assembled to frame) sits in and balances the bike while you cut all wire ties (careful not to snip brake line or electrical feeding the computer). Important tip, take the keys from the pouch and remove both batteries to start the 5-hour charge process, and to reduce much of the weight. The computer is attached to the handlebars with a bundle of cabling, though the bars aren’t attached in the shipping container, so it was a bit cumbersome having to navigate them dangling with fear of damaging the wiring harness. Once out of the styrofoam supports the kickstand won’t work until the front tire is on. Assembly was more involved than I’d hope, though the hour it took my biking buddy and me was mostly spent on trying to adjust the front brake from rubbing. It’s a single piston disc brake, so just one side of the calipers moves as the handbrake is pulled. After much frustration we called it good trying to find a spot of minimal rub. When we tested the rear wheel that was already attached we got the same thing, and can’t adjust it out, so I’ll have to plan a bike shop trip to hopefully remove the warp on each disc. Attaching handlebars to the gooseneck required loosening the computer sliding it out of the way in an awkward manner. Once assembled operation is straightforward, easy and intuitive. Simply hold the power button for 2 seconds and the bright LED headlight illuminates, while the computer screen turns on. Below the power button are an up and down electronic “gear shifter” or max speed control, which cycles through speeds 1 to 3. The right grip has the throttle to provide power. My first ride I thought I’d pedal up the driveway to the road. Not so, the extreme 70 pound weight of the bike (mostly 2 battery packs) prevented me from doing so, but shifting up to 1 with full throttle helped get me to the street. That’s where the e-bike came alive. You’re free to pedal solo, pedal assist, or not pedal at all. While it doesn’t accelerate as snappy as the Polestar 2, it gets pretty quick, while I didn’t get to 28mph max speed mid 20s was faster than I’ve ever “rode” before. I’d suggest a bike helmet for street riding. Note: The original spec stated 62 mile range, but in the US (where eBikes are less restrictive than UK, elsewhere) they’re now using larger batteries capable of producing an impressive 90-mile range. Pros + Fun Factor + VIdeo guided instruction + Environment friendly + Practical Transportation + Low near zero maintenance + Puncture resistant Kevlar coated tires + Carbon belt (avoid greasy chain) + Releasable batteries to charge indoor + Y-cable to charge both simultaneously + double keys one for each battery security Cons -heavy weight trying to pedal uphill -3 speed single drive vs gear shift for climbing hills -assembly takes patience (use video instead) -lacks front fork suspension -could be more peppy like an EV car -heavy, hard to pedal uphill without drive activated -both front and back wheels rub, limited adjustability -single piston brake limits adjustments variability Conclusion *high expectations lead to initial frustration during assembly due to both front and rear disc brakes rubbing, but once assembled and acclimated this bike is pure fun and helped me re-engage with the love of bike riding (but without all the work) If you’re an extreme mountain biker the 70 pound weight and lack of 7 or 10 gear shifter would severely challenge, but if you’re looking for an electric transportation device that’s fun to ride yet practical and economical then you may like to give this a try. Recommend Buy, but expect a trip to the bike shop to straighten the disc brakes.

Biking an NIU BQI-C3 PRO Electric Bike has been a very positive experience. I loved it and looking forward to doing plenty of additional miles in the weeks ahead. This is not my first electric bike and I have a daily commute with a different model. The NIU-BQI particularities attracted my attention for its promise of outstanding mileage (up to 90 miles) with the double batteries and its carbon belt drive. The bike was delivered home in a heavy box where I was able to find all the components properly protected and the tools for the bike setup. It’s also not the first bike that I am building but in total, unpackaging and putting the different components together took me (alone) no more than 30 min: all very intuitive. The batteries are delivered with 15% of power for your first run. The specs: The bike has a nice display to see basic data, including the speed and front light. Following legal requirements include also a bell. The bike is a rear motor type and both wheels have disk brakes. As already mentioned the carbon belt drive that provides a bigger lifespan and no more oil. A full-size saddle. I am a 207 lb guy and living in a quick hilly area, in my first tests, I tried especially the torque power of the electrical assistance and adding some extra weight with my son on the back of the bike. Very impressive delivery with almost 350 lbs in total. The bike is bringing a single mechanical gear and three levels of electrical support (from 1 to 3) and the option for no electrical support at all. The electrical changes are accessible with your left hand. The throttle bottom to accelerate is on the right side. After the first test and short distance, it was the moment to fully charge the batteries. The specs are indicating a charging time of 5 hrs but my experience from 0% to 100% in my first two charges has been more in the 6.30 hrs. Today Sunday, I did my long run with the full battery with the objective of a real test about speed, battery capacity, and riding comfort. Few notes: .- Two fully charged batteries gave me a total of 41.03 miles (please remember my weight and see details), an average speed of 16.1 mph, with a total 2642 ft elevation gain (very hilly area). In some areas with heavy hills, I have an elevation gain from 0 to 136 feet reaching a speed of 28 mph with assistance three. .- Downhill I reached a Max speed 51 kmh (31.7mph) but the bike has a limited speed of 28 mph max speed using the pedal and electrical support three. .- With one single mechanical gear and considering how heavy the bike is with two batteries, biking without electrical support (level 0) is only possible downhill with the assistance of inertia. .- With intensive use of electrical assistance during the first hour and an average speed of 30 kmh (18.6 mph) I used 50% of the batteries. The distance at that moment was 19 miles. .- The biking experience thanks to the fat wheels is awesome. During my trip, I did road, dirt, and gravel and the stability and comfort are one of the best that I experienced ever. .- With more conservative biking, the remaining 50% battery provided me with the remaining 22 miles. .- This total trip was a nice ride that didn't require a huge physical effort. This makes this bike a great option for people in all types of shape. A final consideration after the full trip. This is an electric bike with single mechanical gear so trying to use the right level of support with the electrical power is part of the ride. It took me some miles to realize that the electrical support is more than more or less assistance. The wrong combination makes your pedaling inefficient, but when the power is included in the equation, you see that you could have a total of 4 speeds to deal with different terrains. And all of this, learning again how to learn to bike and use the gears is exciting! A final element to indicate, the manufacturer is offering a 2-year guarantee in part, and work is also an indicator I love it and the times ahead to use it.

It has an excellent battery life. I was able to bike from the east side to Seattle and back totaling 37.63 miles and still have 62% of battery left. This translates to about 99 miles range. That’s very impressive. I was at level 0 going down hill, 0 or 1 on flat surface, 2 going up medium slope, and 3 for steep slope. This was the 4th ride I did. On the first ride, for some reason after about 7 miles, the screen shut off and no power to the bike. I had to stop and then was able to turn on the display quickly and everything was good again. This was a really weird experience, but it has not happened again since. However, I have only done 4 rides so far with today being the longest. The other rides were about 8.9 miles and that normally left me with about 90% battery. One other thing is that the motor seemed to want to grip on to the bike because sometimes when I go from level 1 to 0 on downhill or level surface, I had to push harder as if it’s not just letting the bike go. In this situation, the motor should just let it go and let the pedaling moving the bike. Anyway, not sure what’s going on there. If it weren’t for the pedaling issue here, I would have given it a 5 stars.

When FedEx pulls up and drops off this box, you will quickly find it's pretty heavy, so you may want to recruit a neighbor's assistance. It's about 90 pounds if I recall. Assembly was straightforward but tedious, especially aligning the front wheel and brake. As you screw in the handlebar, make sure you tighten the 4 screws evenly and make sure the "bullseye" icon faces forward. Once it was assembled, I took it for a spin. What a blast! I've only ever rode road bikes, so being able to fly along with no (or minimal) pedal effort is amazing. The 3 "speeds" correspond to how fast you want to go. I found that "speed" 2 is best for tooling around the neighborhood. Put it on 3 and start pedaling...you can get to 29 mph with ease. The LCD display shows several metrics and does track how much you pedal (assist or otherwise) in the form of kcal burned. If you aren't pedaling, it won't track manual stats, obviously. The design is really nice and the V frame is certainly unique. Regarding the brakes I feel like they should have put hydraulic brakes on this, but the included ones do the job. The weight of the bike and rider (I'm 160 lbs) is definitely noticeable while turning and braking. The head/tail lights are nice and the circle halo on the front is pretty unique looking. Even though I haven't ever owned an eBike, I can tell this bike that it's more suited for power/assisted bicycling versus one with multiple gears. The "chain" is pretty genius but takes some getting used to. If you are already traveling fast (say, 20 mph) and you start to vigorously pedal, you will feel a "spinout" from the pedal and gears. What I've found, ironically, is the bike will fly if you just pedal gently. When on #3 assist, you can pedal very slow and be racing along at like 26 mph. It's kind of amazing, honestly. I'm not sure how to address a flat tire if I'm out stuck somewhere, but I imagine parts would be sold directly by NIU and that a basic patch kit will work. It just feels like parts for this are so specific and unlikely to be stocked by your local bike shop, so keep that in mind. I could be wrong, however. Overall, this is one of the best things I've owned in a while. Been biking my whole life but at 44 I am starting to feel it...being able to sit there and be "driven" by your bicycle at a moment's notice with zero effort is pretty sweet. I've been ~30 miles in so far (weather been bad) and the batteries are at like 70%. That's impressive. Put it this way, my wife immediately said we have to buy her one now. Life's too short to miss out on fun times together, and this eBike certainly fills a missing void we never realized we had. Highly recommended!

Love the bike but there is a few things to be aware before buying. 1. It says it will go up to 90 miles on a charge, it will not. Fully charged on setting three pedal assist going the 27.8 mph you may get about 30 miles. 2. There is zero suspension so if you are riding on bumpy or rough roads it is not the bike for you. 3.If you just use throttle it will only go 20 mph. 4. I upgraded the seat already because it was uncomfortable. 5. If you are looking to pedal this bike without pedal assist. It is a bit hard because it is belt driven and there is no gears so you can only pedal so fast before it feels like you’re just paddling with zero resistance. Also looking to upgrade the front forks to have some suspension. Overall though the bike is a good time and a lot of fun.

It has been now 1 year since I bought the NIU bike. This is not a regular bike, meaning you can't just ride it without assistance. It is too heavy to be ridden around without the e motor assisting. I use it like a e-moped for commuting. My commute to work is about 10 mile one way with some hills. I can get about 35 miles and still have 50% battery life left. however, those 35 miles are with level 3 assist and usually at top speeds of 25 to 28 mph. I have a regular bike I use for more standard biking experience but the NIU works amazing for commuting to and from work.

Ohmygosh Awesomesauceness!!! Ordered this week got it today, quick delivery, put it together myself, while watching video from website. It's self explanatory, directions easy to follow. Unpacked it, put it together and riding I went!!! Great quality, very strong, lights are bright on screen and front head lights. Easy to use, just click button to change speed from 1, 2, 3... holds my weight with no problem, I'm 5'7" and 230... Very smooth... Love it!!! Worth every penny!!! Thank you Best Buy!!!

I really like it, now that I’ve learned how to ride it! Acceleration is really good using the peddle assist 25 mph consistently and 27.8 top speed. The only downside is no front suspension! If our streets were in better condition it wouldn’t be an issue! As an in town commute bike it’s a quality built bike that’s been well designed!

Little early still to be telling with my reviews, I am a special case though as I use it for both commercial commuting and personal. I've done door dash with it, and it's the great white steed of my pest control business I've launched with AI as my co pilot With a goal of 5-10 services a week, weather permitting I can commute safely with pesticides in tow trailblazing the path to local e bike regulation I plan to help the DEC learn to cope with the inevitable onslaught of these affordable vehicles not only getting tax rebates but written off as business expenses for entrepreneur like me. The batteries are concerning but they pop in and out so seamlessly and have survived me getting caught in a total downpour once already. The charge lasts long enough for me to get from watervilet to downtown Albany in 30 minutes and still have 76% charge and can ride around the city for about an hour and a half, start making my way home at 30% these bikes are too heavy to take upstairs unless storing for a length of time get a friend to help. Due to the low frame and lack of suspension you must be careful approaching curbs. Making sure the front bike wheel is tight and doesn't move is super important I've had difficulty fighting with the front tire and unable to install the fender without issues grinding. The neck of the bike tightening and retightening gets annoying too for maintenance the handle bar may slip up or down from a significant shock like coming off a curb but maintaining balance isn't hard. The step through design is convenient but my muscle memory of lifting my leg high has not gone away. This bike is cheap for good reasons but the batteries last long and it's likely through saved gas expenses, door dash and regular commuting on it should pay for itself within 6 months. Depending on your credit score the gas savings alone can cover an above minimum payment for the best buy financing. If it lasts years I'll consider buying more of these NIU models for my business. I will contact the maker and my local bike shop for advice, this bike has been able to handle the cargo load I wanted from it as a cargo e bike. Says up to 130kg which is 290 lbs, me plus my bags of pest control equipment falls short of that for lighter services. With a stronger e bike that can handle more weight ill be able to strap an 14ft expanding ladder to it. I'm looking at those options now

Do not buy this bike. For following reason, 1. Speed limit is 20 on motor and with assist it is 21, unless you are lance Armstrong with added magic it may take you to 24. 2. The tires are way too low quality, they will not grip. 3. The motor is out within few months, and best buy has only 14 day return, and good luck with Niu support. 4. It does not have suspension. So good luck to your back. 5. It's better to burn 2K, rather than buying this low quality bike and getting frustrated

I used it for 5 days, but it does have a 90-mile range in both battery. And there refund policy is so hard.

Took it for a road test and rode 2 miles one way using pedals half of the time. At the end of the round trip of 4 miles there was ONLY 80% of the charge in BOTH batteries left! The 4 miles ride used up 20% of charge in each battery! That's 10% for every 2 miles, which equals ONLY to 20 miles distance on fully charged batteries until they are completely depleted, not 90 miles. Keep in mind that fully depleting your ebike batteries to 0% is not recommended as it will shorten your battery's life span, not to mention you don't want to ride your ebike back home with depleted batteries. So, Not even 20 miles out of it, but more like 16 miles if I use 80% of the batteries. This e-bike is great, solid, big and heavy, easy to get on and off but can't ride too far out because of the problem with batteries. Conclusion: Unfortunately, must have gotten lemon batteries that discharge at an unbelievably fast rate, which is frankly disappointing cause I really like the bike regardless of it not being top notch. Great ebike, but mine gets Only 16 mile range using 80% of batteries with pedal assistance, which limits me to how far out I can cruise and must monitor the batteries all the time.

We purchased two of these e-bikes, besides missing the keys to swap out the batteries. We loved the bikes at first. One bike developed a lot of movement between the handlebar and the fork. We reached out to niu support and after a few days they asked for pictures. After sending pictures they wanted us to return the scooter to the store. After 3 more emails and 11 days later I was able to make them realize it was not a scooter at all. This back and forth went on for days as they tried to verify the e-bike and when I had purchased it. After proof of sale vin number and 21 pictures later they informed me that shipping it back to their service facility was the best option. This bike is huge, heavy and I was in not way going to ship this to anyone. Both wheels came out of the box out of true. Local bike store fixed that for a fee. One week later brake error came up in the screen. Tried agajn with tech support. 4 days later again they asked us to ship the bike. Niu does not have good support. The cost of the bike is alot and should have good support. We ended up returning to the store.

My bike will only travel up to a distance of 45 miles, not the 90 miles they claim. And will only go 26.5 mph, power cutting out. In this ad, says front suspension, WRONG! This bike has zero suspension, feeling every bump (I trashed the seat, installing a new one with springs). The headlamp is useless at night, not seeing anything in front of the bike, and the taillight doesn't work. The front disc rotor doesn't center in the brake caliper, constant rubbing against the inner brake pad, making a lot of noise. This bike is only good for riding on level roads, will not climb hills. For the overall poor quality, it's way over priced.

This bike is wonderful, it stays charge for a long period of time! I would give this bike a 20 out of 5☺️

My grandson picked his bike out as a birthday gift a little difficulty, putting it together only because nuts and bolts don’t put the tires on is what they screw lever same with the seat same with the handlebars, but pretty easy to install. My grandson loves it. he now has a little independence.

the ebike looks solid but i have had issues with the gears not changing from 1-3 and i have to turn the bike off and come back again or restart. The front brake is very noisy. When it starts to pedal I have a dry sound similar to a clock. toc, toc, toc. I love NiU moto bike, my experiences in China were great but on this ebike, need to keep working.

In general, it is a good product the biggest problem is about the center of gravity it lies in the rear of the bike, which cause my rear tire flat 2 times in 3 month. AND CHANGING REAR TIRE IS PAINFUL good thing is the bike design is great so that I can change it by only removing 6 screws. Strongly suggest adding a tire insert to your rear tire
