I weigh 295 lb was nervous that it wasn't going to be able to handle my weight. I was wrong this is a monster bike . A loving how comfortable it is.
This bike is awesome. Battery is massive. Just went on a 30 mile ride, full throttle with battery to spare. So much fun. Topped out at 33.7 miles a hour down a small hill full throttle! The suspension makes for a smooth ride. I’m on the shorter side 5’7 and I sit on the front seat, so the extended seat wasn’t necessary. Get a lot of people who ask about it and mention how cool it looks. I did a lot of research when looking for a new bike and I couldn’t be happier. Definitely the most bang for your buck with the S4. I love this bike! Hoping to put a lot of miles on this baby!
Easy to assemble. Got a quick response when I had some trouble with a part. The bike is beyond fun and rides easily on all surfaces, from the sidewalks to the streets to the sand. Highly recommend for anyone looking for an e-moped—should be at the top of your wishlist!
So iv been looking for an electric bike for a while , always reading the specs and looking at my options. This bike has everything i ever wanted in a e bike, full suspension, adjustable suspension in the front, double the battery size then the other competitors in this price range, super comfy, rear seat ,1000w motor, gears, and crazy range , also can go pretty fast over 30mph
