    • its a fun ebike for local use
Color: White Style: Standard
updating 3 stars to 5 stars, customer service made it right helping me with the issues i am having. all i am gonna say is, is ebike is more for local use, running to the store, to school, work a friends place, not to be used for delivery, travling far from home, if you wanna do that, get an ebike with 7 speed / 21 speed and larger wheels like 24 inch 26 inch. ... show more

Very sturdy and will put together bike. We added a bag for the rear rack and a bottle holder. My son has so much fun with this and gets great exercise. No problems going on 20 mile rides as far as battery. I wish there was more pedal assist speed levels. Acceleration is smooth and manageable for anybody. ... show more

Great for a ride to the store or around the neighborhood. It’s a bit heavy but the bike is well built. Well worth the money. I’m 5’9” and 180 lbs. rides me with no problem. It’s a fun little bike. More than I expected. 👍
