    Pure City Step Through Bicycles

    Have you ever floated dreamily on a cloud, the fresh breeze and sunshine dancing in your hair as you cruise down to the coffee shop, grocery store, or wherever your day might take you? Have you seen the contagious smile on the face of a young Dutch woman sailing through the city on her bike? Those are the sights and sentiments that inspired us to build our most comfortable bike yet. With a sprung saddle, step-through frame, upright geometry, and swept-back bars, these bikes are made for relaxed revelry, because it’s easier to enjoy your city when you feel good doing it.

    All Shapes and Sizes!

    Everyone deserves a bike that fits, that's why we designed two sizes of our Pure City step-throughs.

    43 cm

    The 43cms were developed to be perfect for riders 4'10" to 5'3". More than just a smaller frame, they feature smaller 26" wheels to lower the ride, shorter crank arms to keep the pedals within reach, and weigh 12.5% less than their 45cm counterparts.

    45 cm

    The 45cm, designed for riders 5'3" to 6'3", feature larger 700c wheels for easier rolling over imperfect roads, longer crank arms for longer legs, and a longer top-tube to prevent "T-rex arms". Because the best bike is the one you love to ride, and the bike you love to ride is the one that fits.

    We've got speeds!

    We designed these bikes to thrive in whatever city you call home. Because not every city is created equally, we built two different gearing options so you can pick that set-up that’s right for you. The 3-speed gives you a small range of gears to cycle through and the internal hub is unmatched for ease of use and creating a clean, minimalist look. The 8-speed gives you a wider range of gears to tackle tough hills and haul heavier loads.

    3 Speed

    • Internal hub for ease of use, a minimalist look, and low maintenance.
    • Shift without pedaling, ideal for cities or stop-and-go riding.
    • Easier to adjust and more reliable than a derailleur.

    8 Speed

    • Wider range of gears for taming hilly cities or hauling heavy loads.
    • Higher top speed before "spinning out".
    • Cheaper to own, repair, and replace.
