Our bikes have fully lugged frames, so they are built on a very strong foundation.   Our frames, chains, spokes, rims, hubs, puncture resistant tubes and Kevlar tires (and many other parts) are all designed  to support heavy weights and long-term use.   It's not just the tires that make a bike Super Sized -- it's a combination of the materials, design, and all of the components.

Right now the only two-wheeled bikes made strong enough for you are our own brand, Zize Bikes.  There are two custom made models.  On this page we’ll explain some of the differences between the Time of Your Life and A New Leaf so that you can understand the differences and choose your ideal bike.

The Time of Your Life was designed to allow the rider to be seated and have his feet touch the ground.  This fundamental difference can dramatically increase the rider’s confidence level.  The center of balance is optimized with characteristics of a Super Sized Cycles customer—legs reaching forward, back straight, eyes headed straight out in front—thus increasing the center of balance and the rider stability.  This bike is designed to work in harmony with your body, not in spite of it.

As a great way to make sure your bike lasts your lifetime, if you start with an easy ratio and are ready for a bigger challenge, you can purchase a Ratio UP!  kit, and bring it to your local bike shop to have them install it.  Conversely, if you start with a Normal gear ratio and decide that you don’t want to work that hard, just get a hold of one of our Ration DOWN! kits, bring it to your bike shop, and you’ll be back in the business of riding just they way you like it.  By the way, you really won’t see any difference in the look of your bike, unless you are very attentive to detail—it’s simply changing the front chain ring and back sprocket.

The goal of Super Sized Cycles is to make biking available to everyone.  The two models we are now making go a long way towards meeting that goal. 

We now have a selection of saddles that will ease your troubles.  The selection is limited right now, but we are on the lookout for awesome, comfortable saddles that allow you to ride without pain or damage.

 t's also a good idea to invest in a pair of cycling shorts  with a padded crotch.   Ours are designed for both men and women.   The difference is unbelievable!

To measure your inseam, get a pencil and a book that has a binding about 2 inches thick.

Take your shoes off and stand facing a wall. Put the book between your legs, with the binding facing up and your feet about 6 inches apart. Hold the book firmly under your crotch - you should feel the same amount of pressure as sitting on your bike saddle. Make sure your legs are straight, and hold the book square against the wall. Mark the spot on the wall at the top of the book. Measure the distance from the floor to the mark - this is your inseam.

For accuracy, repeat the measurement several times and calculate the average. You may need to interpolate for height and shoe size.

All the bikes that we sell can be used whether you weigh 100 pounds or the maximum listed for that bike.  Our brand, Zize Bikes, are designed especially for continuous use, no matter what your weight.  (Which, by the way, is great for those of us whose weight seems to fluctuate with the winds.)

There are some cases where you might want to get a different bike.  For example, let's say you get hooked on riding, and get really into bikes.  You start salivating when you read about the latest Tour de France road bikes.  At this point you may want to add another bike to your repatoire, cause it sounds like you've got it bad.  Or maybe you've discovered mountain biking, and you want a cycle you can really beat up.  Again, time for a different bike. 

You may find, as I have, that one bike is no longer enough.  I now have three, and will be adding more as I find them :)  And each of my bikes serves me well, depending on my mood and the type of ride I'm taking.  If, however, after investing in a Super Sized Cycles, you decide that you want to be a one-bike-person, and it's time to change rides, please send us a note.  We frequently get requests for used Super Sized Cycles, and we'd be happy to help you sell yours.

Our Supersized Personal Activity Vehicle is an awesome way to get around on 3 wheels.  The manufacturer does make an electric-asssit for it, but it is not recommended for over 220 pounds.  If you'd like an electric assist tricycle, we recommend the iZIP Tri-Cruiser.

The short answer is that the bikes are custom-made.  What this means is that each bike is built after we receive your order.  The process included building the frame, powdercoating (like painting) the frame, attaching the parts, and shipping the bike out.,  This generally takes 4 to 6 weeks, if we hit it just right.

Our goal is to have enough inventory that you won't have to wait for your bike, but we're not yet at that point.  The good news is that the wait is well worth it--you'll love your Super Sized Cycle! 

We are happy to ship our Zize Bikes anywhere in the world. 

Some of our other products we are unable to ship due to  manufacturer's guidelines and/or international regulations.  Please send us a note with the product you're interested in as well as the specific address you'd like it shipped to, and we can let you know if we can deliver those items, and at what cost.  If we can't help, we're happy to connect you to sources that may be able to assist you. 

Please note that we cannot ship Nutcase Helmets to locations outside of North America.

Yes!  The payment option is available for any model costing $1000 or more.   You have the option of breaking your invoice into 4 equal monthly payments or into 6 montly payments, with the first one being 25% of the total due.  Due to the fact that we're online only, we have to provide the financing ourselves, so no bikes will be shipped until payment is completed.
