Very peppy e-bike that exceeds the advertised speed and is very fast for it's size. All of the advantages outway the downsides for the e-bike. The bicycle gets around 25 miles on a full charge not the advertised 50, the mechanical breaks get a advantage break speed and distance, and the seat could be a little softer. That's the only downsides, and the advantages are vast. The throttle has a small delay I actually think is a safety feature to stop whiskey throttles, the tires even small are wide making them very stable, the bike has fantastic acceleration and speed, the bike is very stable, folds easily, nice small rear rack, easy battery removal, easy to move from pedal assist to off position pedaling like a standard bicycle and back to pedal assist with just the hit of a button. The size of this e-bike with all of the upsides makes this bicycle worth the price which is very economical. I could go on about everything I enjoy about the bike but I'll spear you all. The most disappointing downside of only 25 miles on a full charge is kind of negated by the easy removal and portability of the battery. You can always go somewhere and charge the battery for the trip home. It does take around 6 hours to fully charge the battery from zero, so take that into account.

My son is going to secondary school next year and I bought him one for Christmas to make it easier for him to get to school. My son is very happy and loves this e-bike! Firstly, it was very easy to set up - everything was intuitive and he was riding it in no time. One of its best features is its portability; the compact folding design makes it easy to store in the trunk of my car. Then it looks very sleek and modern - definitely an eye-catcher! In terms of performance, I was very impressed with its speed; it's perfect for zipping around quickly. The battery life is also very long and the charging time is short, so you can go at any time without having to wait for a long time. What really stands out is the smooth ride quality. Whether it's city streets, sidewalks or slightly rough terrain, the scooter handles it with ease thanks to its sturdy construction and reliable tires. It's also very easy to maneuver, making it perfect for navigating traffic or tight spaces. Overall, this e-bike ticks all the boxes in terms of design, performance and convenience. If you're looking for a reliable, stylish and suitable electric scooter for adults, this is definitely the one to go for. Highly recommended!

For one, this bike is built like a tank. Had a little accident that was due to my negligence. The bike hit the pavement pretty hard but other than a few scratches, all was well. The bike is comfortable and easy to control. With the big tires it handles well in sandy soil. I did need a new security latch used when the bike is unfolded. I contacted support and after providing my order number, they sent it with no questions asked.

Really fast and had a nice kick. You do have to pedal to keep up the speed especially over bumps or it does slow down. The throttle gives it a kick but pedaling give it more of a kick and speed. I don't like how heavy it is very hard to move around and hard to fold back up and lift into a car or something. But other then that it's a great bike for the price. It's wonderful gets me to work and back which is about 5 miles away and I can get there and back and still have a semi full battery. It rides smoothly and feels great when you hit bumps it's a little rocky but still does ok. Off road it's pretty freaking good too. I did run over something that got a hole in the inner tube after just a couple days my bad luck or just not as strong tires as I thought idk. Overall great bike but be ready to pedal more so then other E bikes for that speed.

Very happy with this purchase, bike looks great, is sturdy, battery life is good. Also, I had an issue mounting it (which was my fault, if I'm going to be honest), I was able to reach the Windone team right away and they helped me with my issue, 5 star customer service! Definitely recommended!

Electric Motorcycle This e-bike is a class 2, in addition to pedal-assist it has a throttle and if you are not careful it will throw you backwards causing injury or death. It is very heavy almost 68 ponds, sturdy built as if it was designed for battlefield, cumbersome to fold and unfold. Mine arrived with minor damage. Ride is very stiff and uncomfortable. Changing the bike seat requires changing the seat post as well, once that is done battery removal for charging requires seat post removal. Of course you can charge the battery while battery is attached to the bike. E-bike with throttle are not permitted everywhere, check local laws.

Assembly was rather straight forward, been using it for maybe 2 months and have 70 Miles logged on it,I can definitely say it's awesome to ride and feel the wind blow through your face, it does not fold, to those who think it may this is literally a 75 IBS chunk of 20MPH steel, it's very powerful for an E-Bike and definetly worth the money for those who weigh a bit more than most E-Bikes support. I have noticed the front mud guard isn't exactly stable however which is the only downside but all in all a fun and worth it purchase for small distance commutes and joyrides

Nice e-bike, but there’s an electronic issue that causes it to shut down while riding. Not sure if it’s a loose connection, or some other malfunction. Took a while to assemble and I really didn’t want to return it, but no other option.
