    Greaat Value!

    I use this bike basically as a scooter. Its battery lasts long, gets up to 18.5 MPH on a flat surface, and is comfortable for such a small bike. The only negative is the 1 gear is not great for pedaling, sso its not a bike that will deliver much exercise, but it gets you where you want to go for very little dough!

    Seat issues

    The bike is awesome. Has great battery life…my only issue is the seat will not stay up no matter how tight you get it!

  10. Jade

    Nice bike

    Very good product

  11. LiFen Zhen


    Good bike but not as fast as my other one. Heavy.

  12. Brittany S.

    Some info not true

    I use this bike everyday at work. It’s great and super fun. The 18mph is not true. I have two of them and they both won’t go over 15.5 mph. Besides that it’s a great toy.


    Good for the price

    Overall it’s a good Bike. The only problem is that when you are using electric mode and you want to pedal you feel there is no traction on the pedals. The bike is faster than the pedals can run.



    Nice bike

  15. Keith Chesser

    It’s amazing and a lot of fun

  16. Parry S

  17. Rita Tipple

    Nice bike with some limitations

    Generally, I am satisfied with this bike. At 190 pounds it zips me along at 15 mph with no problem. The only thing that I dislike about the bike is a safety consideration. With only 14″ wheels there isn’t much gyroscopic stability that you have come to expect with bikes with larger diameter wheels and an angled front fork. When I was a kid my bike would almost steer itself. I could take my hands off the handlebars, and the bike would track well. On this little bike I have to keep both hands on the handlebars to feel that I am in control of the steering. I am not even comfortable giving hand signals for a turn. Bumps on the pavement are also more of a problem with the small wheels. My strategy is to go slowly and to wear my helmet.

    Pretty nice 👍

    It was fast , maneuverable, simple.

  24. MR HANDY

    Lots of fun!

    This electric bike is awesome. It is very compact and easy to transport. You can use it as a regular bike or an electric bike. It holds a nice charge and you can get 15+ miles on a single charge. The speed is just perfect where you don’t feel that it’s dangerous at all. Very nice bike and I am getting one for my wife as well! Highly recommended!

    I love this bike! The speed is great, the size is perfect. I wouldn’t recommend if you are riding through rocks or mountains but definitely great on smooth surfaces like the sidewalk or street.

    Great little bike!!!

    This is an awesome electric bike! It came well packaged and pretty much already put together. There are different modes of you hold down the M button. So if you find you aren’t going very fast it’s because you need to change modes. Going up inclines are easy and only need slight assistance. I find that riding this feels safer than a scooter. Highly recommend!

    It is a good size and moves nicely.

    I did not like that there is no manual on how the digital panel is set up or what the functions mean.

    Fantastic Value

    A surprisingly good E-bike especially for the price. A little trouble up large hills and off-road, but nothing has stopped it, only slowed it down. With the pedal assist you can easily go off the road for a minute if traffic demands it and the small suspension absorbs a surprising amount of force.

  36. R. Williams

    Nice EBike

    We have only had this Ebike a week or so and therefore cannot rate battery life but after some minor assembly and charging the battery it is just what we wanted. It performs as expected and we anticipate using it a lot.

  37. Juliana Ratliff


    Very easy to inflate and deflate. I had no idea it was so huge and it’s also a bit more firm than I was expecting.

  38. Michelle Blasky

    I LOVE this bike!

    I love the style. It’s very comfortable to ride. The battery life is good. Speed is also good.
