    Disappointed
    Set this thing up and the tech won't work and renders the bike useless. Stuck on Level 1 and won't progress past 5 seconds. Doesn't recognise move state or manual control. Absolutely gutted.

    After one month of use no issues
    It is not only stylish and well designed, but also sturdy and good quality. Everything seems to fit perfectly. Easy to assemble. Very quiet. Great seat and pedals. Only one issue: the top spinning levels could be a bit harder than they are.

    Straight forward
    Simple and easy to set up. I have been using it almost everyday and it feels great to use every time (about 1 month of use now). Premium quality feel, highly recommended.
