Great bike
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

Great e-bike and top customer service!
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!

Great support service
Absolutely amazing support, my kid loves the bike, range is great, sturdy. The only thing is that for me I feel somehow a slight unbalance on my hands when driving, like there is more weight in the left side, but the bike is great and it’s a minor thing. Support is really great.

Runs a bit large, and has electrical issue.
Nice e-bike, but thereâs an electronic issue that causes it to shut down while riding. Not sure if itâs a loose connection, or some other malfunction. Took a while to assemble and I really didnât want to return it, but no other option.

Feeling secure
I love riding the bike. I am 65 and have a taller ebike but I don’t feel secure on the taller bike. I love having to ave a key to ri ad remove the battery. Much harder for someone to steal it. My only draw back is the back tires keeps losing air.

Good bile for the price
It has speed as stated (20 MPH pedal assist and 17 thrust only), installation was vary basic, it has a good build. The only problem it is not very comfortable around tough terrain because it does not have shocks absorbers.

Do not buy. Save yourselves the trouble.
A mega fail. Never felt less safe on any bike or motored vehicle. So many issues.The throttle goes from not working to being FAR too sensitive- literally flying off the handle. The battery goes from 60% to zero. The bike is waaaaay too heavy. Does not fold. Not nearly as comfortable as a thing its size should be. I owned and rode many e-bikes- this was hands down the absolute worst. I hope they take back this total lemon. It should not be sold on amazon.

its cool bike with wide tires .
I recently got this Electric Bike, and I couldnât be happier with my purchase. The installation was a fast , taking just about an hour to complete. This bikeâs long battery life is impressiveâit comfortably takes me around Santa Monica Beach with family and friends, making our outings fun and worry-free.The bikeâs stylish, fashionable design turns heads everywhere we go. Not only does it look cool, but the suspension also feels great, providing a smooth ride even on rougher paths. Charging the battery is convenient too, with a full charge taking roughly four hours. The weight of the bike makes me feel secure and safe while riding.Overall, I highly recommend
