I usually ride a 26 inch bike but with a fat tire bike a 20 inch bike fit is much better more comfortable easy to fold easy to assemble I am enjoying it my main advise is anyone buying a fat tire bike for the fist time remember fat tires add 3 inches to the bike keep that in mind when sizing your bike Also I noticed some posts about not being able to get motor to start make sure the battery is lined up and pushed completely in also make sure the battery locks into position well and the key is in the on position when you utilize the peddle assist I love the bike fit the peddle assist works great battery charged completely in 4 hours. This bike has given me additional freedom and ability to get some exercise ... show more

    • Struggle Win
I ordered this Bike for my 8-year-old son for Christmas. Everything assembled easy and the Bike looked great, but the battery would not seat down into the proper position, so when he was riding it, the bike would just shut off. After many conversations with their customer service which was good once I got in touch with someone might I add but it was a common issue and they quickly sent me out a new battery casing. It was easy to install and once I got it on and got the battery slide adjusted properly the bike worked great and so far, we have not had any issues with it. We are coming upon 7 months of ownership with 5 of those months of consistent riding. Now after many camping trips and a few off road rides the bike is still going strong without any issues. I would recommend this bike for the value to any young or even adult person for their first E-Bike. Just remember this is a 20-inch bike and due to being a Fat Tire Bike it will add around 3 inches in height. Great Bike! ... show more

    • Inexpensive compared to others, and it works amazing
I love how I can pedal and get a great workout but then can use pedal assist here and there as needed. I get 40 miles in a day on it with battery life still on battery. I use it on country, hilly roads. Very worth it. Tons of power

    • Battery may not be shipped together with bike
Aside from the battery not being shipped together with the bike, it's was fairly easy to figure out regarding assembly. But, im very disappointed because the battery won't hold a charge. After I charged it for 10 hours, I unplugged it and when I was ready to use it. The battery was completely drained. This is a series of unfortunate events and it seems that im not the only customer dealing with the same issues. ... show more

    • Great bike
I'm not a fan of buying certain things online. That being said, things shoes, clothes, food. And now bikes. This was great and fun to ride but yet was 1 problem, it was too tall in the seating for me to comfortably place my feet on the ground. I had the seat all the way down but still had me on my toes at every stop. So this is 1 of the things you try on first. Like clothing. ... show more

    • The unit was a lot of fun until I started developing electrical issues.
Review Image by Darryll Darryll
Halfway through the estimated life cycles of supplied battery, the base of the battery melted, causing connectivity issues. There was also some melting that occurred to the docking plate itself. Another issue I found with this model is weight to breaking ratio. In other words, the bike is a little too heavy for the braking system. Constant adjustment is needed in order to avoid dangerous situations. ... show more

The media could not be loaded. First of all, I'll say that the “500W Motor”, “20" x 4.0 Fat Tire” electric bike, this is one of the cheapest, but that doesn't mean the quality of the product is good. When I received it, I found a lot of problems, some small problems, such as the peeling paint; and some were potentially big problems, such as a noisy front wheel and the rear tire. I emailed the problems to the customer service center, and they sent me a video of how to install the rear wheel, which I tried to do. As for the front wheel noise, it was temporarily resolved after I used WD-40. However, two months later, I found that the noise became more and more serious. After some careful inspection, it was found that the front wheel turned irregularly, non-circular. I found that the axle was bent, and the wheel and brake disc was deformed. I reported to the customer service center again, and about 10 days later received a new front wheel rim, it only a rim, no tires, so I had to remove the original tire and install it on the new rim. After installing the new wheel hub, the front brake made a serious noise, and I had to remove the front brake to adjust, and put it back on again, the problem was solved. I don't know what other problems I will encounter next, but I hope the charging is safe and the battery will not explode. As for the feeling of riding a bike, I would like to say that with 500W of power, the acceleration is extremely strong, even too strong when you just want to ride slowly, you can only turn off the power, otherwise every time you step on the pedal will have very strong acceleration, and you'll have to use the brake for slowly. So, if you want power ride, strong acceleration, and a cheap electric bike, this is a good choice, but you have to solve various problems yourself. If you want a hassle-free, leisurely bike, it is recommended that you would rather spend a little more before buying a better-quality bike. ... show more

    • Looks good, never worked (Update)
The bike was easy to assembly but the battery never changed/never worked. I charged it for the recommend 10 hours nothing. Don’t waste your time on this. And the seller as yet to reach back to me in a refund. Waste of time and money, this is what this bike cost me. The tools that came with the bike worked well but you still need a flash head screw driver and a Phillips head screw driver for a few parts of the assembly. Also the first stem of the bike as way way way to much play for when you riding. I’m able to spin the whole stem around easily with out any effort. Once again don’t buy this bike. No customer support also so be very careful ordering this bike Update 04/28/2021 after getting in contact with their Facebook page, they actually helped fix, and get my bike up and running. ... show more
