    Best bike in the price range hands down

    I've sent this thing off cliffs, I've wrecked into trees, Viciously rode this thing on mountain bike trails, pulled my kids on sleds in the snow, you name it. This bike is a TANK. 750miles and counting and the only thing ive changed is the brakes (once) because I let my very heavy set father ride it a few times. Ill be buying 2 more in the future. Maybe more >:) Seriously cant recommend these things enough.

    Frickin’ Awesome!

    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!

    This Moped is a game changer!

    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!
