Bike Reviews
  1. one year ago

    My bike was a lifeline as a kid; i rode everywhere. When I was older, it was my favorite fitness activity; I rode a hundred miles or more a week. After getting married and having kids, I just…stopped. Now my son and daughter want to ride, and I want to share that with them ,as well as improve my own health so I can be around for them for many years. My old bike is uncomfortable and unsafe given my size, so I am thrilled with my Zize Bike. It’s everything I remember!

    I had 2 leg surgeries in 3 years which left me somewhat immobile for walking, but biking is a great second!

    It’s great to feel like a kid again – no worries riding as fast as my legs take me!

Part Recumbant, Part Comfort Bike, Part Traditional Bike. All Wonderful!

The Contour Seat is amazing!  The seating surface is a full 16″ wide, which supports your entire bottom, and over 2 ½” of high density injected molded foam, which provides cushioning and ‘oh my gosh’ comfort.

  • The removable, fully adjustable backrest provides lumbar support.
  • The entire seat is supported by dual seat struts and a beefed-up, locking seat post tube.
  • The Contour Seat is covered in a stretch fabric with a waterproof backing and comes with a nice attached backrest bag to keep your odds and ends in.
  • We’re happy to introduce the Samson, the newest addition to our bike line.
  • With its beefed-up frame, dual seat struts, upgraded cranks, hubs, and bottom bracket, the Samson is not only incredibly comfortable but also sturdy.
  • The Samson boasts a one-of-a-kind cockpit that includes a 16″ injection molded seat and contoured backrest. A lower seat allows both feet to easily reach the ground when stopped and a low step over simplifies entry and exit.
  • The Samson’s easy to reach handlebars allow you to sit up and relax, eliminating stress on the wrists, neck, shoulders, low back, and crotch while providing a commanding view of the road.

Note: This bike MUST be assembled at a bicycle shop.  You may indicate which shop you’d like to use, or you may ask us to find a shop near you.  Call us at 877-690-1879 if you want help with this!
