Customer Ratings & Reviews

Bike is amazing, I use it as a daily commuter. I travel nearly 45 miles each day using this bike. The motor has plenty of torque to make it extremely comfortable going uphill. I use a trailer for this bike. I have my 115lb GSD with me for the longer trips before we may get to the walking. I acquired a second set of batteries for a long trip I plan on taking of upwards to 300 miles I will attempt. If you are holding a lot of weight, but still within the weight requirements of something like 360lbs, you can make it uphill. Put in minimal effort, but you'll be glad you got this. MAJOR ISSUES HALTING FROM 5 STARS: The bolts and screws that were fastened by the manufacturer did not hold for more then 50 miles before coming loose. I have had minor damage requiring removal of fenders and replaced hardware. I know vibration causes this normally, but for the price I paid of $2,199 I expected to feel safe immediately. I now check all bolts and screws after each 30 miles or so. Zero suspension, you WILL feel every bump and rock from the seat. You will need to use your legs a bit to soften the ride by standing. Great bike, on sale.

Definitely stylish and sleek. A modern look and feel. Not too cheaply made. I put it together alone and it wasn’t too bad. They include all of the tools needed but I would recommend someone helping you assemble it for less annoyance and time, but definitely not too bad and easier than most I would guess. It has a seamless feel to the way it all operates. No gears. Just one continuous speed from the belt drive instead of a traditional 7-speed chain gear system. It will not need maintenance like a steel chain and will last forever. Doesn’t have the same feel as a traditional bike when riding. You ghost pedal mostly. Not a bike for exercise. Commuters dream in a warm climate for smooth roads at all times. This bike will excel in places where you will have always smooth surfaces to ride on. This bike does NOT go over bumps well at all. Very painful going over even small bumps and especially big ones. There is no shock absorbing on this bike which is why it doesn’t have good traction. But, the tires ARE decent, just not good for anything but the smoothest of surfaces. So a commuter bike is the main point here. If you live somewhere where the roads are immaculate and especially have dedicated bike paths, this one is for you. do not get this one for any kind of off-road activity. This is a great one for year-round warm climates and paved environments. That is truly where this bike will shine. It has a daytime running light, a headlight, a taillight and a brake light. The range is quite good and the the dual battery containers built-in to the design is nice. Can charge both batteries simultaneously. Has a bell and an easy throttle button. Comfortable seat. I never get discomfort when riding from the seat at all. The acceleration is good and can easily exceed 20mph. Brakes are good. Again, not necessarily needing hydraulics for where this bike is meant to be used, in warm, smooth areas. I’m not a bike aficionado and this is my first bike I’ve purchased. Prior, I’ve only ridden on one eBike and was very intrigued by them because I had no idea how fun and practical they are. I first rode on a Lectric brand bike. I’ve ridden this NiU bike for 30 miles on the odometer so far. What attracted me the most to buy this bike was the range advertised and the carbon belt drive system. I don’t think this bike offers anything overly remarkable that you couldn’t get from another bike in the same price range. I think the only reason to buy this bike is if it you are going to use it in the exact environment it is designed to be used for. In that case, you are getting a premium bike that is way more efficient because it is not equipped with unnecessary things like shocks and hydraulics that will drive the price up and instead you were getting something that has superior designs to maximize efficiency and seamlessness, hence why this is totally a commuters dream bike. Not all terrain, not an exercise, not an off road bike. Not even close. Get this for what and who it’s made for.

Great bike with a powerful motor. The only issue I have is with the front fender and quality of the brackets.

Good fun to ride. Needs suspension though. I use this to commute to work & do local errands. It's a wonderful way to get around!!

Great electric bike. We rode with the pedal assist on a level one for over one hour and only used 7 percent battery. When the bike is unplugged the battery stays charged up. I love the design and the bike height is great for my 5 ft 3 height. We have added mirrors and a phone holder as well as a basket in the front for our 10 pound chihuahua. I feel the price is reasonable and I would highly recommend this bike.

Mileage range grossly understate is 45 miles if that its also a pedal assist electric not electric bike..you.have to pedal or its not moving. Slow charging bike . Battery full.ladt 4 to 5 hours but you have to baby sit it if you go max level 3 it will eat 25% in 5 miles ..its heavy so if your out battery its a challenge

I bought this bike in June of this year and had a issue with the bike shutting off and the rear hub clicking. I contacted NIU in July and asked if they could send a replacement wheel to me and they said they will not send a single part to a customer and the only way to get anything repaired is to send the entire bike to Ontario Canada to their repair facility which is absolutely ridiculous. I received a RMA number and return instructions in August and shipped it out. They received it a week later and in a few week I received an email stating the repair is completed and the bike was being sent back. I received the out for delivery alert a week later then received a message stating it was being returned to sender. And that's the last info I received. 3 months past and I didn't receive any info even though I called and emailed weekly. Fast forward to today nearly 4 months later and without any email or call and after all the failed communication without any response the bike randomly showed up this afternoon. It was in the same box I shipped it out in and it was completed destroy. The bike not only wasn't worked on it was pulled out of the box and just shoved back in loosely with no support and the fork was bent completely in half and the wheel and handlebar were loosely banging around with no support. Please do not buy from this company, buy an Aventon product as they are much better at dealing with issues.

Mine came with stripped screws so I cannot adjust the handlebars. My front tire won’t sit evenly leaving more space on one side causing it to shake at higher speeds. No suspension. Wish I had done more research. It’s fast and fun but bumpy and defective.

One of the best investments we made at best buy was our electric bikes. Look forward to using them as much as possible this year as we move towards living healthier lives

omggggg i love this bike so much, i use to put off going on bike ride but with this bike it’s so easy and fun. i’ve only had it for a week but i can say ill never buy any other bike.

The bike was easy to put together, it only took about 15 minutes. It already had some charge to the battery, it went 28 miles per hour. Great!

Love this bike, very durable and reliable. Excellent miles on the batteries as well!

Excellent bike, fast charging , I recommend this bike, the charge lasts a long time, good quality, good durable tires.

The bike got a hall error code (error code 3) 16 days after purchase, this error makes it unusable. Avoid this bike and NIU technologies. Their response times are disrespectfully slow. The bike lasted 125 miles. Best Buy's return policy is 15 days. Best buy won't honor a return even after explaining to the representatives in store and to the corporate representatives over the phone that I was assured a manufacturer warranty at the time of purchase. NIU Technologies does not provide warranty services to Puerto Rico, and Hawaii, and select other locations (I currently live and purchased this bike in PR). I was lied to by the store representatives. This is my last purchase with Best Buy, I feel scammed.

Good to ride, easy to assemble, nice looking eBike

I like a lot of things about this e-bike but not every aspect is exactly how I imagined it would be before it arrived. I knew going in that it was going to be large and heavy due to the specs for packaging and when it shipped, I got a clearer picture of that reality. But it is genuinely massive. All the tubes on the frame and even the wheels and tires are thick and well built. It feels very high quality, and it weighs over 70lbs as well so that brings some limitations as far as how you use and store it. For example, you’re not going to be able to use a hitch mounted bike carrier for this bike, as I have not encountered any that have a weight capacity that would accommodate it, and between the V shaped frame and fenders over the tires you won’t be able to hook stabilizer bars to it on such a rack either. So, transporting it is difficult, you’re limited to truck beds or something along those lines if you want to take it anywhere before venturing out on a ride. Storing it is also a little more complex due to that same weight and frame shape issue. Many wall racks just can’t hold a bike this heavy, nor would you want to be lifting it up like that. So, you more than likely will have to plan on keeping it on the ground and may be unable to take it anywhere unless you have a truck, leaving you finding a large space for storing it and then hopefully you have places to go with it from your home. There are a few reasons why it’s so heavy, first and foremost is the dual battery arrangement. You can charge them simultaneously with the included charging adapter and then the bike uses both for power while you ride which is where the long-advertised range comes from. In my experience so far, I don’t see how you could actually get 90 miles out of it on a single charge unless you are going slower and not using much of the motor assist as you pedal along. I have ridden it on a couple 10-mile round trips going between level 2 and 3 of the motor assists and generally come back with about 60% charge remaining after those 10 miles. With those assist settings combined with active pedaling you can indeed go up to 28mph assuming your pavement is very flat, and you don’t have too much headwind with the assist at level 3 which is the highest it goes. More often than not I find it hovering around 23-25mph since those perfect circumstances are relatively rare for top speed. The other issue is that pedaling feels a little unbalanced, I struggle to keep a good rhythm since it varies the resistance you feel in the pedals more than I would like. So sometimes my downstroke feels loose, and I lose my stride a bit. Another problem I have run into is it seems to not do well with big bumps, at one point I hit a bump at speed that was more aggressive than I was anticipating, and the bike actually shut down entirely. I still had momentum and it took me a few second to notice but I had to restart the bike mid ride. I think the batteries may have jostled out of place just enough when that happened but I’m not completely sure. On that note removable batteries may be a bit of a negative, but the positive is that you can get spares and swap them out on the fly to keep going and in the long run a bad battery won’t reduce the bike to a big piece of e-waste. The suggestion about putting a 13lb spare battery in a backpack and riding with that is somewhat comical to me but it is an option should you need it. I like the large bright screen which shows lots of useful information such as charge, speed, mileage, calories burned and more and it is easy to use and see in the bright outdoors. The bike also has a nice DRL on the front, brake light that does light up when you use the brakes, and a rear running light what works along with the headlight when activated. It is belt driven rather than using a chain which is very quiet and low maintenance. NIU claims that the belt will last over 10x longer than a chain though that will take a long time to be sure about. It is very powerful and a comfortable ride on nice tires that take minor imperfections in the road extremely well. The brakes work well, and while they seem to lack substantial stopping power that may once again be due to the amount of weight they’re being tasked with between the bike itself and the rider. The seat is nice and wide, comfortable to sit on, and easy to quickly adjust. The handles are just the right shape, and the way you engage the motor for full electric power is a thumb toggle on the right side which is easy to use and does not have excessive resistance. The left side has the power button and an up and down button for interacting with the screen. It is a straightforward bike, looks very nice, and works very well. The top speed is achievable but inconsistent, the maximum range seems to be a bit of a pipe dream, but it is fast and can go farther and most other e-bikes I have seen on the market. Don’t hit bumps too hard and plan on using it from your home and it’s a great bike. Not perfect but I look forward to enjoying it for a long time. If it fits those conditions for you then I recommend it.

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.

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.

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.
