    Bike is Working Well

    I bought two Gosen A8 bikes for my wife and myself. They arrived in 2 days and were well packaged. The assembly was quite easy. Since it's winter here, we've driven both bikes just a few times to try them out and check for defects. So far, nothing major. The gears on one bike required adjustment and every nut and bolt needed to be checked because many were not tight. My biggest complaint is the lack of a comprehensive owners manual covering the numerous programming parameters for the digital readout and personal settings. There are YouTube videos available from various people but nothing from the company so you can't be sure the information you are being told is accurate for this bike. Looking forward to many years of use.

    Your pictures are so good!
    Thank you for your trust and support!


    Amazing performance and great quality. Quick delivery. Perfect for Canada winter.

    Great bike

    I love the bike! Lots of power! I’ve put 615 miles on it so far this year and it’s still going strong!!

    Excellent value

    Solid bike. Lots of power. Excellent fit and finish. Arrived ahead of schedule. .Feel I got more than my moneys worth.
    Excellent customer service.
    Purchased two. One for myself, one for my wife.
    It was too big for my wife, so I had to return one.
    NO PROBLEM, no question.. I wish all vendors were so easy to work with.
    Purchased a folding model from Gosen for her. She loves it.
    We had always ridden 26 inch frame bikes, so I didn't give it much thought.
    The fat tires really increase the seat height.
    Website indicated 5 ft 8 inch rider.
    I'm 5 ft. 8 in. and had to modify mine a little to get my short little leg over it. If you are 5 ft 10 in. I think you would have no problem
