Ergonomics is the art and science of designing to the human body

Bicycle ergonomics is about applying science to meet the physical needs of the human body. Why would a company dedicate itself to this task? The belief at Cruzbike Inc is that with today's science and design capability, there is no reason to present the body with excess stress and discomfort and to do so is to compromise the ability of the rider to ride safely. The optimal ergonomics of the cruzbike prevents wasted physical and mental effort.

To quote wikipedia: Ergonomics is the science of designing ... to fit the worker. Proper ergonomic design is necessary to prevent repetitive strain injuries, which can develop over time and can lead to long-term disability.

Long term disability is found in the many riders who can no longer enjoy cycling without suffering pain in various parts of the anatomy. With the ergonomically correct bicycle design of the cruzbike, this pain disappears.

The Cruzbike lets you use a wide range of muscle groups, as with a standard bike, which strangely is something other recumbents don't allow. On other recumbents the mantra is "relax your arms and upper body" as there is no way they can contribute to the riding activity. On other recumbents, the focus is on building up your "bent legs" to compensate for taking the rest of your body out of the equation - and so many riders see a deterioration in their performance for at least two months. On a cruzbike there is no such adjustment period as you can apply your same cycling talent as you would on your normal bike.

The whole body's proper engagement with the bicycle avoids wasted effort

On a standard bike, you can and do use your arms. This is possible because you pull on the handlebars at right angles to the steering tube. Only in extreme cases, like the dash to the finishing line, does the pull on the handlebars make the bike wobble. Effectively then, on both a standard bike and on the Cruzbike, the frame including the handlebars is solid enough to hang onto and dig in. And as you do, you benefit by:

  • Building bone density throughout the whole body;
  • Achieving a low-impact workout;
  • Getting upper body resistance training;
  • Developing leg and upper body strength, including various muscle groups such as the lower arms, upper arms, shoulders, pecs, abs, back, as well as development of the leg muscles; and
  • Producing more power of course!

As with walking, running or riding a standard bike, there is a natural bodily rhythm to riding a Cruzbike. Movement of the bottom bracket introduces slight variety into the joint movement and so protects against knee injury and knee pain. Unnecessary effort and pain is something you can leave to folks on other bikes.

The Cruzbike creates the perfect balance of arm, torso and leg effort. So you are able to give that little extra something just when you need it most. That is what we mean by the art and science of bicycle ergonomics - all the advantages of an upright bicycle, without the health risks and discomfort of the usual riding position. We are serious when we say we are delivering you all of the benefits but none of the drawbacks - that is the bottom line of our front wheel drive technology.

I've ridden many top of the

I've ridden many top of the line rear wheel drive (RWD) recumbent bikes.  After tens of thousands of miles (slow learner) I finally became frustrated with the fact that my upper body was getting absolutely NO attention.  In fact, on my RACE ACROSS THE WEST in 2010 I hung loops on the handlebars so that my hands and arms could just `hang' there.  For all practical purposes I could have sent my arms, core and shoulders off to lunch while I rode the RWD recumbent. 

When climbing hills and mountains on a RWD recumbent I was at a loss, watching upright cyclists rocket past me as they got out of the saddle, rocked the bike back and forth, using their arms and shoulders for maximum effort. 

Finally, on many of the high end RWD recumbents there is a `riser tube' that comes straight up from the head tube as much as 17 inches.  In order to save weight the riser tube is typically lightweight delicate (weak) metal.  If I were to attempt to pull in on the handlebars to gain the benefit of my upper body power ... the riser tube will simple crack right off!  In fact, I was warned by the manufacturer of one of the most popular RWD recumbents NOT to pull on the handlebar because ... "it is unsafe and the riser will crack off." 

While doing night riding (particular 24+ hour rides and races) the riser tube obstructed my ability to see the road ahead of me.  The more reclined I became the less of the road I could see.  This resulted in multiple incidents of riding into potholes or road impediments. 

Limiting my cycling to just my leg power makes it certain that I will be the last  man up the hill, that I will be at a significant disadvantage when I need to accelerate. 

I made my decision to ride the Cruzbikes (Sofrider, Silvio and Vendetta) last year.  The FWD and movable bottom bracket allow me the get the most out of both my bike and my body.

I have ridden my traditional road bike for 25+ years and have hit downhill speeds up to sixty mph. How does CruzBike do on down hills? How does it handle. Is it faster or slower than  the Standard Road bike?

Hello, I have been riding a

Hello,

I have been riding a Cruzbike for about 2 years on many different terrains.  I have found that the Cruzbike is very stable on fast decents due to your feet are holding the front wheel stable.  I had a Bacchetta Strada, and found that I was more confident on decents overall on my Cruzbike.

If you consider that to get the most speed out of a road bike on decents you have to go into an extreem tuck and holding your head up can become a chore, the reclined position of the Cruzbike presents about the same frontage area but with a better, more relaxed body position and a better view of the road ahead.
