    Great bike

    I live in a hilly rural terrain and I’ve used it 2 weeks to commute to work. Must have done 350 km. So far so good. I love the bike. The only thing is that I never received the seat extension. It wasn’t in the box.

    Richard Lefebvre

    Love the S4…. It’s a powerhouse and a blast to ride. The big fat 20” tires make it a playful sturdy fun bike that handles rough and smooth terrain.

    Great bike deal!

    Really exceeded my expectations.
    Comfortable and fun to ride plus picks up quick!
