Easy assembly! This E-bike works great to get around everywhere and is comfortable and reliable. A very smooth ride too, and quiet! Easy to charge, and holds a charge well before having to be charged again. I had a question and received a quick response & outstanding customer service!

Great bike. Lots of battery life, nice display, fat tires for a smooth ride, geared well if you want to peddle, and sufficient speed electrically. Also folds for transport. Well made and worth the money.

Great battery life, speed acceleration is great. Durable on and off the pavement. Easy to assemble. Easy to fold and move around to store or take in vehicle. Bought for husband and now in process of purchasing another one for myself. My adult son wants to purchase as well. Delivery was quick and very responsive if any questions or concerns. Love the bright color on the orange. Great to take out and enjoy the weather or a trail. Great price for the design, functions, and durability.

I ordered two of these, one for me and one for my wife. Both came promptly and in good condition save one issue, the LCD screen on my wife's bike was damaged in transit. I contacted the seller and they immediately sent me a new screen. It was easy to replaceand now I have two perfect bikes.Assembly of the bikes were easy out of the box. The batteries came fully charged and after inflating the tires to the proper pressure we were off.The bike is easy to operate and even though I haven't ridden a bike in over twenty years, this thing is a joy to use. The fat tires make the bike all terrain. This bike feels sturdy! I weigh over 250 lbs and not once have I felt like I'm too much for this bike. The ability to fold this bike makes it easy to transport without the need to fit your car or SUV with a hitch-rack. Beware, this bike is heavy! So even though you can fit it in a trunk, depending on your strength, you may need another person to help you lift it out.All in all, a great bike for the price. Would definitely recommend.

Great eBike
Reviewed in the United States on October 17, 2024

I have had this Narrak eBike about 3 weeks. I've got another eBike so I have something to compare this one to. Where to begin? I love this bike. I started out looking for a folding ebike and came across this on Amazon. The reviews on Amazon were excellent and the price is super affordable so I went for it. I had one immediate upgrade I wanted to do and that had to do with the gearing. I was ghost pedaling at PAS 3 and even some in PAS 2. I don't like that "clown pedaling" feeling. So I did some research and ended up getting a 48T front chain ring. The Narrak comes with a 40T front chain ring which is quite small. The rear flywheel is a Shamano 14-28T which I have kept the same. Just going to a larger front ring has made the gearing much nicer. I have no ghost pedaling up to about 18 mph and can pedal in PAS 4 to get that. I thought about upgrading the rear flywheel to an 11-28T which would give me better pedaling at the highest speeds PAS 4-5. However, that would come at a cost of higher gearing in the mid range. And I like my mid range where it is now and love the low range too. I ride in some hilly, mountainous areas and this bike gets me up and down like a pro. I like to pedal myself but will use throttle on challenging areas. I don't know if ebikers realize that when you do some pedaling your battery lasts way longer than if your are at full speed throttle the entire ride. That is not my style and I am getting good mileage on the battery so far. Not sure yet how far I can go but this bike is not that hard to ride at 0 PAS so I feel I could always get home on it. I think it's going to get around 45 miles on a charge if I push it that far. I put some Flat Out in the tires and that's another key I used on my other bike. Gotta have it. Stuff lasts the life of the tire. The ride is very smooth and balanced. The 4x20" tires are great. I have 4x26 on my other bike and like the wide tires. I can ride Narrak with no hands which shows that it is well balanced bike. That's another important thing for me. It makes the ride like a super glide. I also really like the size of this bike. My other bike is really tall. I'm 5'8" and this bike is so easy for me to get on and off. The adjustable seat has springs and works well. And I did fold the bike up and put it in my car and it fit in the back. Pretty cool feature. I also have a rack which is what I use most of the time but it's good to know you can make this bike into small bike. So there you have it. I'm an experienced eBiker, and mountain biker and this bike lets me go where I want to go. Happy trails all!

A big guy review

As the title suggests I am a large human that occasionally gets mistaken for a shaved bear. A little over 300lbs and 6’5”. I bought this bike because of the excellent reviews on the customer service.The unboxing wasn’t bad and quite easy to put together. The battery was about half charged and I put that on the charger in the same area I put the bike together in. Please for safety keep this in the same room you are in, just in case it decides to have issues. The manual was well written and had decent pictures to help.After the battery Was charged (thankfully with zero issues) I plugged it in and took a 4 mile drive with factory settings. I expected to get about 65-70% of the speeds that a normal sized human could get, and likely nowhere near the top speeds, I was pleasantly surprised to find myself going 23 on flat ground with good acceleration! I have put 14 miles on it in the last 24 hours and battery is sitting about 60%. No hills and a combination of pedal assist and throttle. I did unlock the bike to full potential today and got it to 29mph on flat ground!Took it to my local bike shop (and wow the bike turned some heads!) and added some sealant to the tubes for those inevitable goat heads, and now I have an impressive e-bike that moves a bear sized human around nicely!You will need to make some adjustments to brakes and shifter due to rough riding in a delivery truck but the manual helps a lot with those adjustments.After reading a lot of e-bike reviews I always read about how hard they are to pedal due to the weight. I understand how a tiny person could have issues moving a 60 some pound bike around I found it no different than pedaling my marlin 7. But again my legs are very used to moving a lot of weight around.
Everything works so far and I haven’t had any issues in the first 24.I will update if anything changes, as of now worth the money.

I've had the ebike a few months now. It arrived on date expected, was well packaged and easy to assemble. It has now been used on road and off-road with ease. I did have a small accident, hit a rock straight on, but the bike endured with just a scrape. I wish I would have been that lucky. The charge has a lot of life, it lasts forever. The bike is easy to use both in manual and auto mode. It will get you where you want, and quickly if you are brave enough. My husband has one too, we are very glad we puchased them. Looking forward to many more miles of enjoyment.

It's a great bike, however it takes awhile to break the breaks in and it has a slow break, it almost takes me about 20-50ft to stop depending on my speed as well as how quick I stop it. It's not an automatic break. If you plan getting a different seat it seems you'll need a different seat rod. It's perfect for my height 5'3 I just didn't realize how big this bike was so not really ideal for apartment dwellers if your by yourself trying to get it upstairs. I really enjoy and love this bike don't get me wrong. My bike won't go into the 2nd or 1st gear for some reason and it stays on 3. When I do put it into those gears it makes a lot of clanking noises and refuses to pedal, which is fine with me I use full throttle anyway since its my first time riding any type of bike. I'll just ease into 3rd pedal overtime. I've also noticed that it's kind of hard to pedal, my friend also noticed that when he was helping me learn it, his bike was far easier to pedal. Wasn't comfortable for my height though. I enjoy the twist throttle on it because it's simple and easy, the horn is my favorite because it's very loud but awesome at the same time, and it was very easy to put together. Love the speed and love the motor noises very nice. I do love the bike.

This e-bike is my primary mode of transportation and it required quite a lot of time to research properly. When I started shopping for a bike, I had certain criteria, such as wide, low pressure tires (to handle difficult terrain and a smoother ride) and a step-through frame for ease of use (I'm a bit older guy and not fond of swinging my leg over a traditional frame) as well as tires that are aggressively treaded for use with snow. I have not been disappointed with this bike. Through inclement weather and potholes, I have no barriers. It is perhaps not as fast as some others normally, but a very good owner's manual will detail how to tweak the default settings toward better speeds (at the expense of battery power). Unfortunately, the seat supplied with this is better suited to female anatomy, but a simple replacement will address this. I did, after all.It is worth noting that this is not built for speed, but utility. Better speeds are possible, but for commuter use it is actually quite good. It is also for a single rider, not for cargo or passengers. The cargo deck has a warning on the deck that it is not for a load in excess of 25 kg. A quick trip to the hardware store has its limits, but all my other shopping is done by bus. I recommend only a single rider with a backpack at most, and within those limits I have had no problems. A very good bike for the money, and if you're looking for something different, try looking further. I recommend this unit for use within the parameters I specified, but for anything more, you may have to keep looking as there are some fine bikes available that may fit your needs better.

5.0 out of 5 stars Love it!

You can see I added a back rack bag, basket, and some of my own stickers. The red color is beautiful, but found it chipped fairly easy when i removed the wheels to add tire liners for flat prevention. But, as a nice touch they include a small bottle of touch up paint that took care of that. I advise that it is a good idea to watch some YouTube videos on how to change an ebike rear tire as it can be confusing if you don't know how. Also, when removing the rear wheel I took pictures and labeled each bolt, washer, and position as I removed it. It was easy to assembly out of the box with most things already together. Everything has worked perfectly, and I really appreciate that the manual is very helpful even including all the "P" settings to remove the default limit of 22 mph to max. I found it will do the 28 mph as indicated and have hit 32 on a downgrade. I wanted an extra battery as back up or if I want to take a long ride to carry it on the rack. I've only gone a longer ride of 13 miles so far due to the cold weather, but would estimate that around 25 miles on a charge is reasonable using mostly throttle with sime PAS. I contacted Narrak ebike and they were really helpful in getting me the correct battery for this ebike. The batteries on their website are 2 pin batteries, but as you can see in the picture mine takes a 3 pin battery. The people at Narrak had me email them a picture of my bike and battery to insure they sent me the correct battery. I received the correct one. Real nice they provide 4 keys for each battery!
So, I'm so pleased with the bike and that you can get parts if you need them. Nice bike and helpful people at Narrak to assist you. Thanks.
