Strong Bikes

A Strong Bike Makes All the Difference

When we were young, biking meant freedom!

No more walking
You didn't need to be chauffeured
Freedom to go where you wanted, on your own power

Ah, but things have changed. Somehow the years and the pounds have multiplied, an

d perhaps bike riding has gone off the program? And why is that? The majority of

bicycle companies today don’t make cycles for big people, strong bikes that are built to comfortably support bodies that are bigger than 200 pounds. In fact, to ride on one of these bikes is to invite trouble and there have been no options available for the heavy bike rider. Until now.

Now is the time to step up to Zize Bikes®, the only place you will find strong bikes, designed for people who are plus sized.

Our bicycles are proudly made in Vermont, USA by Super Sized Cycles. They are not over-welded adaptations that are difficult or embarrassing to ride, they are sleek, easy-to-ride machines. They are bicycles whose design flows along classic lines, using unique design concepts and exciting new components that provide a durable, safe and comfortable ride.

They say a picture is worth a thousand words, but one picture is not enough to show you the compelling design concepts utilized by Super Sized Cycles and found no place else and built exclusively for people who are big. We invite you to look through and see the future in bicycling. Study, choose, and join the fun.

Our Frames

Custom Built Bikes don't have anything on our Frames!

Big 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 from the aircraft industry, which provides a stronger base than steel or iron, yet retains subtle flexibility and lightness. This alloys kept the bicycle from being too heavy, yet provides a comfortable ride.

The structural integrity will last for a lifetime of riding.

Our frames are built with aircraft-grade seamless chrome-moly
Our frame material thicker than anywhere else in the industry
Using rolled, seamless tubing means your frame will never split

Our Brakes

Extra Large Bikes Require Extra Strong Brakes

Who doesn't remember the little rubber pads attached to the end of the calipers as being all that stood between you and stopping? For the XL bicycle rider that would not be enough. Selecting the modern disc brakes that are becoming standard on more elite bicycles was the superior way to look at this element. Gone is the brake fade we all remember, and so too is any sense of urgency whenever you feel the need to use your 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.

Our Saddles

Heavy Riders Need Comfortable, Stable Seats

On any bike the seat is the comfort zone. Tires are where the rubber meets the road, but this is where the human meets the bike. And as we gain in age it's more important than ever.

Our seats are wide, padded and built for comfort
Tested from many designs to provide hours of easy riding.
Seat posts are firmly locked to the bike—no quick-release levers (which can mean a sliding seat)
Seat clamps are integrated inside the post, which means no wiggling seat for heavy riders

The solid connection of the seat to the bike frame will give you the direct feel of the bike and raise your confidence riding, 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.

Our Tires

Bikes for Big Riders Require Big Tires and Wheels

The tires you see on most bikes today haven't changed much since the days when you first started riding. But for bigger folks, it makes sense that we're going to need something more than thin tires with low thread counts that seem to get flat just by looking at a bumpy road.

We created super strong tires that take big people and the bikes they ride through rough terrain and smooth. These are better tires that transport riding a bike from a task of appreciating friction to gliding on air. For big riders it is a matter of, once again, adding to confidence in riding through nearly effortless motion and positive feel of the road.

- Our wheels are wide, but not so ride that they can't fit into most standard forks
- Our spokes are 14-15 gauge, the strongest in the industry
- We use 36 double-butted stainless steel spokes per wheel
- Our tires measure 2.4", and great for support and stability
- Our tires are three times more durable than traditional cruiser bike tires
- Our tires have well rounded side walls for ease in handling
- The smoothness of our tires creates low rolling resistance
- Our inner tubes are sealed with Slime® so it keeps the tires from losing air or getting flats

Our Pedals

Why You Need Tougher Pedals and Cranks

While the pedal assembly may seem simple, it is actually a cantilevered piece that absorbs all the rider's weight when pedaling, especially under the stress of going uphill or obtaining speed.

For the plus sized rider this is a crucial component. We didn't need to look further than to the area in biking where the bikes are stressed on a regular basis—the world of BMX racing. The parts selected for our Zize Bikes will easily stand up to a plus size rider.

Shimano® anodized aluminum cranks for integrated strength
Heavy duty steel alloy platform pedals
Pedals with oversized cartridge bearings to keep the pedals in place all the time
Pedals are mounted close to the crank, eliminating bending

Our Cruisers

The Gears Make You Feel like You're on a Customized Cruiser Bike!

If you've never ridden with internal gears before, you are in for a wonderful surprise! No more gears slipping, no more grease on your pants leg, no more chains falling off, no more timing of the shifting. With our Shimano designed, internal gear system, you no longer have to think about the standard dérailleur with its plethora of open gears, exposed chain and the requisite grease and oil. The ease with which you can change speeds truly will make you feel like you're on a customized bike.

Riders can shift gears faster, easier, and in any position, including at a full stop
90% easier to use than external gears
Adjust your gears once, almost no need for further adjustments
Stronger than external gear systems
Chains NEVER fall off

Our Finish

A Custom Built Bicycle Finish

Zize Bikes are assembled with the care of a limited run feeling. Paint, the standard, less expensive option, would chip and ding quickly and soon enough lose the allure of the flowing lines. We spend the extra time to powder coat our bikes. The polished glass look in the photos is what you will find when you remove your bike from the shipping box. Durable, and beautiful,it's the custom built bicycle finish you deserve.
