    • Great for the price
Style: S16/Black
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. ... show more

    • Easy to carry and fast travel speed
Style: S16/Black
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! ... show more

    • Great bike and even better customer service
Style: K2/Black
Review Image by Jeffrey Jeffrey
Customer service is good and they really take their responsibilities. At first the inner front tire I received is defective, or maybe my fault mis-operated the installment. Anyway it pops out from the outer tire and not able to hold air. I contacted them and they sent me a new inner tire right away. However, since I do not have tools to re-install tire, I had to contact them again and asked whether they can just send me a new whole set of front wheel, and they did! Now it is working well after some time waiting shipping parts. I appreciate how seller responds to my problem and request. Bike is sturdy and ride is smooth. It is time to enjoy this e-bike during upcoming summer season! ☀️ ... show more

I would have given a five star review if it didn't have damage and alignment problems. There is a broken nut, a crooked display (that can't be straightened), a loose washer in the box that isn't known where it belongs, and a crooked handlebar stem. I would like a new nut, even though it appears that I would need to disconnect wires to the gears to replace it. Update: More damage recognized...a dent on the right rear fender. And when tightened, the handlebar stem still has play when turning the wheel. ... show more

    • its cool bike with wide tires .
Style: K2/Black
I recently got this Electric Bike, and I couldn’t be happier with my purchase. The installation was a fast , taking just about an hour to complete. This bike’s long battery life is impressive—it comfortably takes me around Santa Monica Beach with family and friends, making our outings fun and worry-free. The bike’s 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 ... show more

This bike is for any beginner or other. Value for the money, simplicity of design, quality workmanship. I recently bought this e-bike, and it been a great choice. The battery life is impressive, providing a long range on a single charge. What stands out the most is its reliability I am been using it daily without any issues. The electric assist is responsive, and I find the overall performance to be smooth. This e-bike has made my daily commuting much more efficient and enjoyable. If you are looking for a reliable e-bike with a good range, I am recommend checking this one out! ... show more

This bike is amazing! Perfect size for my husband. I ordered this for his birthday / Christmas. He really likes it. It reminds him about his motorcycle, nice speed and ride smoothly. The assembly was not bad at all. It took him around 30 minutes and good to go. The quality is decent and sturdy. The weight is pretty heavy. So far, everything is good! He really enjoys it.
