Take on paved roads, local bike paths or gravel trails with the Zize 29er Max 2.0 bike. It's built for comfort with a cushy saddle, wide tires and an adjustable stem—and it can carry 450 lbs.

  • Features

    • Durable bike is factory-tested to support up to 450 lbs. and is designed specifically for heavy riders, enabling you to move comfortably and easily around town
    • Each component is selected for significantly higher strength and durability than is typical in standard bikes to create a balanced, sturdy ride
    • Aircraft-grade chromoly frame with TIG welding is exceptionally strong and built to last
    • Wide, upright handlebar with a substantial, adjustable stem allows for an upright cycling position around town and on the trail
    • Wider, shock-absorbing seat uses a double-clamped seatpost to keep the saddle in place
    • Shimano freewheel provides 8 internal gears for smooth shifting; internally geared hub helps make your rides more energy-efficient and reduces chain slippage
    • High-strength cranks withstand increased pedaling force
    • Mechanical disc brakes provide superior stopping power
    • 36 spokes and double-wall rims increase wheel strength
    • Wide tires (29 x 2.1 in.) with a high thread count are ideal for multi-surface use, offering stability in softer conditions and speed on smoother surfaces
    • Built to ride for many years, this bike was designed and tested by a heavy person in the USA
    • Specs and images are subject to change
