ZiZZO Bikes

THE #1 FUN MACHINE

All the FUN, none of the hassles

Hassle#1:

Can't Ride Home.

Solution:With ZiZZO, it is now possible to simply ride one way. You are no longer stuck to riding both ways (there and back). If you are too tired, got too dark or if it starts to rain, you have the flexibility to simply fold up the bike and hop on a bus or call Uber. This flexibility opens the door for more bike riding whether for a day trip or a city commute. Want to extend your trip? A combination of riding with other forms of transportation gives you the flexibility to ride or get a ride.


Hassle#2:

Security and Storage

Solution:

Who said you can’t take it with you? You can! One of the greatest benefits of ZiZZO bicycles is that you can take them wherever you go. Ride a ZiZZO in the park, to your school, the coffee shop, your office. When folded, ZiZZO can fit under a desk, in a closet or under a table. No need to lock it outside, in the rain or otherwise risk it getting stolen.

Hassle#3:

Security and Storage

Solution:

Two or more ZiZZO bicycles can fit into a trunk of a car. You can even leave one stored in the trunk and no one will know until you pull it out to ride it. You are always ready for an impromptu ride or an emergency. Many times people have decided not to take a bike ride at the waterfront or in the park just because they don’t want to go through the chore hassle of installing the bike racks on the car and mounting the bikes.

Hassle#4:

Can't Share Your Ride

Solution:

ZiZZO's unique folding design allows one bike to fit most rider sizes and styles. The fully adjustable seat post and handle bar stem makes the ZiZZO is ideally suited for male or female, teen or senior and riders from 4’8” to 6’3”. Your family will never out grow a ZiZZO. It can be passed along or shared for years to come.

Hassle#5:

Which Bike IS Right For You?

Solution:

ZiZZO is the “All-around” bike. If you’re looking for a fun, easy to ride, comfortable and safe bike, then ZiZZO is right for you.ZiZZO was designed from the ground up with three things in mind: performance, comfort, safety. We looked at everything from the tires and grips to the number of teeth on the gears to determine the best combination for a ride that you would expect whether on city streets, park trails, or around the beach and campsites.

The Science:

Engineered to 

Ride Light, Strong and "Big"

Frame: Strong, Light and Rigid

How a small wheeled bike can ride BIG

The frame is the heart of the bicycle's integrity. It is the most important part that determines the performance and safety of the bike. A lot of engineering and material science go into designing a frame that is strong, rigid and lightweight. These are contrary engineering objectives: a rigid frame can be brittle and easily cracked, a steel frame can be strong, but heavy. Typically, as the strength to weight ratio of a frame increases, the cost increases exponentially.​Rigidity or stiffness of the frame determines the efficiency in transferring a rider’s energy in pedaling into propelling the bike forward. If a frame is not rigid, the force applied to pedaling will be wasted by flexing the frame from side to side rather than powering the bike forward. The more rigid the frame, the more responsive and faster the bike since the energy of pedaling will transfer power directly to turning the wheel.​ZiZZO is quite an engineering feat considering that when the frame unfolds and lock together it becomes more rigid than most traditional bikes, comparable to expensive mountain and road bikes costing thousands of dollars (click for complete test results). The aluminum alloy frame gives it the best strength to weight ratio at an affordable cost. Typically when people consider a folding bike, they think: under-performance, slow, unstable and hard to pedal. ZiZZO's goal is not to develop a “folding bike” but an all-around performance bike that folds. Due to it’s strong, rigid and light frame design, people all over are amazed at how well ZiZZO bikes function. They are absolutely fun to ride: fast, quick, easy and safe.  

Gear Inches:

How a small wheeled bike can ride "BIG"

Gearing or gears and gear inches are the great equalizer in cycling. They can turn a small 20” wheeled bike into a world record speed machine as in the case of Bluenose when in 2013 at 83.13 MPH set the world speed record for a bike. What it all boils down to is designing front and rear gear sizes that will provide the correct gear inches, or the distance you move per revolution of the crank arm.​ 


 In the case of typical mountain bikes, gear inches range from 25” in your lowest gear to 87” in your high gear (Trek 820). In the case of your average road bike, the range is 28” in your low to 120” in your highest gear (Diamondback Century). In the case of the EuroMini, the bike was designed for an “all around” ride and we chose a range from 30” in the lowest gear to 87” in the highest gear.​ 


 What all these numbers mean is this: ZiZZO is designed to ride as easily up a hill as your typical road bike and as fast as your average mountain bike.

Wheel Size:

Why smaller CAN be better!

There are 5 fundamental advantages a bike would come equipped with smaller 20” wheels.​ 


 1. As mentioned in"Gear Inches" 20" wheeled bikes can ride fast like record setting Bluenose. They are quicker accelerating; because 20” wheels are lighter and have less mass, they have less moment of inertia. In stop and go riding, the quicker acceleration of a smaller wheel translates to a more efficient ride.​ 


 2. More agile; like their BMX counterpart, 20” Small wheels create a more maneuverable bike. Because of their size, they are more responsive to steering and they present increased tire compliance with the road surface because they get higher pressure per square inch on the ground. The superior maneuverability is particularly helpful on wet surfaces and in tight turns. In addition, the overall compact size with fat tires makes the bike sturdier and more comfortable as a whole.​ 


 3. Strength; 20” wheels are inherently stronger than their larger counter parts. Shorter spokes mean stronger wheels. Because a 20-inch wheel has a smaller circumference than a larger 26-29” wheel, the rim is structurally stronger and resists deformation from impact. 


 4. Fit; Easier to fit a wider range of riders. The larger wheels requires bigger bike frame geometry overall, making 26”, 27” and 29” wheel equipped bikes more suitable for bigger or taller riders. Whereas ZiZZO can fit male and female from 4’8” to 6’3”.​ 


 5. Size and weight. Because the ZiZZO is a bike that folds, it smartly takes advantage of a smaller wheel’s portability and lighter weight.​ 


 The only drawback of smaller wheels is that they do not negotiate over obstacles as well. This is typically a non-issue since most bike ridings are on a pave or dirt road. Plus, the EuroMini’s wide balloon tires add suspension to compensate for the smaller wheels

Geometry:

Stack, Reach and Angles

Stack, reach, and the two angles (headtube and seat tube) are the main ways that a traditional bike is measured. These are important measurements for bikes that determine just how comfortable and agile a bike will ride. As the diagram shows, the wheel base, and both the headtube and seat tube angles are comparable to a typical mountain bike. When looking at bike sizes, the measurement that changes is the stack and reach. ZiZZO bikes uniquely get around problems with sizing frames by making the seat post adjustable (thereby being able to change the stack height) and designing the stem to be adjustable (changing the reach). Being able to adjust these to lengths allows riders of differing heights to ride the same bike while maintaining the similar angles and wheelbase as traditional bikes.​ 


 Fit solutions are just one advantage of ZiZZO bikes. Because of their adjust-ability, you can change rider position to your preferred riding style, from an upright casual ride to a lower profile commute on the go.

Comfort:

Just how comfortable can a ZiZZO be?

Rider comfort comes from where your body interfaces with the bike. That’s the handlebar and seat. We talked about how the ZiZZO frame is more rigid than most traditional frame. Rigidity, as discussed can make a rider more efficient, transferring pedaling energy into powering the bike forward, but it can fatigue a rider as well when the stiffness of the bike transfers all the shocks from bumps and holes of the road directly to the riders arms and back. To overcome the challenge of providing comfort for a stiff frame, ZiZZO bikes are designed to flex at the seat post and handlebar stem. This provides the comfort to the the rider, mile after mile of biking.​In other words, the ZiZZO is rigid and efficient where it needs to be, but supple and comfortable where you want it to be.

 Fit solutions are just one advantage of ZiZZO bikes. Because of their adjust-ability, you can change rider position to your preferred riding style, from an upright casual ride to a lower profile commute on the go.

Tested & Trusted

ZiZZO bikes have been rigorously tested for strength and stiffness. We tested our bikes using three standard tests: Lateral Bending Stiffness, Tire Contact Lateral Bending Stiffness, and Front Triangle Stiffness. Independent testing company, Bike Testing, Inc. in the USA has proven that the ZiZZO has an overall stiffness rating comparable to traditional bikes costing thousands! That’s right, our bikes performed as well, if not better than some professional bikes but at a fraction of their price!

 Fit solutions are just one advantage of ZiZZO bikes. Because of their adjust-ability, you can change rider position to your preferred riding style, from an upright casual ride to a lower profile commute on the go.

Test #1 

PROCEDURE: LATERAL BENDING STIFFNESS - 

KLEIN METHOD

The frame is positioned horizontally on the test-bed and the head tube is clamped securely and rigidly to the head tube test-bed fixture. The bottom bracket shell rests firmly on the test bed and is simply supported at a height, which positions the frame in the horizontal plane. A solid dummy rear axle is clamped into the rear fork-ends (in the case of adjustable type rear fork ends the dummy rear axle is positioned such as to make the wheel base as short as possible). Deflection measurements are taken from the top of the dummy rear axle with a 0.001-inch dial indicator. Weights are hung from the bottom of the dummy rear axle and measurements are taken with four different pre-loads, each time measuring the deflection caused by adding a 3.0-pound weight.

Test #2 

PROCEDURE: TIRE CONTACT LATERAL BENDING STIFFNESS

The frame is positioned horizontally and clamped at the head tube bearings. The bearings are held rigidly so that the frame can rotate about the bearings. A bar is installed into the BB which clamps onto the BB shell and positions the BB 1 1/2" from a stand which the bar rests on. The bar has a rounded end on it to allow the BB to rotate on the stand. Oil is placed on the stand at the contact point to further allow movement. An axle is bolted into the rear dropouts which has a bar attached to it 90 degrees from the plane of the axle. The axle/ bar represent the rear wheel. The bar extending from the axle is placed into position so that the bar intersects the point at which the wheel makes contact with the ground. Weights are placed onto the contact point and deflection is measured to determine stiffness.

Test #3 

PROCEDURE: FRONT TRIANGLE STIFFNESS-

KLEIN METHOD

The frame is positioned horizontally on the test-bed and the head tube is clamped securely and rigidly to the head tube test-bed fixture. The torsion-testing lever is bolted rigidly into the bottom bracket shell and projects horizontally in the opposite direction of the seat tube. While the bottom bracket shell rests firmly on the elevated portion of the test bed it is otherwise unrestrained. During the measurement the frame has no additional equipment mounted on it nor is it restrained in any other way. Deflection measurements are made by applying torque to the bottom bracket shell by means of the torsion-testing lever (which is pre-marked at 30.5 inches from the center of the bottom bracket shell). The angular deflection of the bottom bracket shell is measured by measuring the total angular deflection of the torsion-testing lever and subtracting the deflection that occurs in the torsion-testing lever itself. The resultant bottom bracket torsion rigidity is calculated as torque expressed in ft-lbs, divided by the angular deflection in degrees.
