Heavy riders know instinctively that bike frames may be precarious. The key to making a superior bike for our customers is in the frame. We use chrome-moly steel tubing designed for the aircraft industry, which provides a stronger base than steel or iron, yet retains subtle flexibility and lightness. This keeps the bicycle from being too heavy, yet provides a comfortable ride.

Remember the little rubber pads attached to the end of the calipers that you’d use to stop a bike? For the heavy rider, that wouldn’t be enough. That’s why Zize Bikes have modern disc brakes instead of standard rim brakes. Whether you use your brakes to stop gently in front of your favorite coffee shop when you’re out for an afternoon ride or for an emergency stop heading downhill, you’ll be able to ride in confidence.

On any bike the seat is the comfort zone. After thousands of hours of testing and several iterations, we are confident that you will love riding on our wide, padded seats. Because our seat clamps are integrated inside the post, you’ll never worry about a wiggling seat and you can ride with total confidence. Whether you’re meandering on a country lane or negotiating traffic in a city. Every rider expects this connection, and with Zize Bikes, heavy riders meet, and exceed, these same expectations.
