POWER

Racing and record-setting demonstrate the power and performance of Cruzbike’s technology. The core of the drive system is Cruzbike’s unique Dynamic-Boom Front Wheel Drive (DB-FWD), which is our version of the MBB-FWD system originally patented by Tom Traylor, and then improved and patented by John Tolhurst.

The advantage of DB-FWD is the linkage of the upper and lower body across the drivetrain as it rotates around the axis of the head tube. This linkage allows you to boost power when climbing or sprinting by engaging the upper body in much the same way professional cyclists do when they climb or sprint on standard road bikes.

PERFORMANCE

Take a look at this slow-motion video of Lance Armstrong as he climbs. As his left leg makes the powerful downstroke, his upper body and core muscles, through his grip on the handlebars, force the frame to lean to the right, an action which forces the left pedal upward at the same time he is pushing it down– thus putting more force across the left crank. Simultaneously, the leaning-action of the frame is pushing the right pedal downward at the same time he is pulling up on the right pedal, thus applying more force through the right crank.

By using upper body muscles to move the frame to the right, he is dynamically shortening the distance between his left hip and left pedal during the compressive downstroke, while increasing the distance between the right hip and the right pedal during the tension-producing upstroke of the right leg, thereby getting more power into the cranks than he could otherwise. A split-second later, the pattern is repeated as he leans the bike to the left during the powerful downstroke of the right leg. Cruzbike’s DB-FWD system works similarly, except the axis of the “lean” is rotated approximately 73 degrees; from the horizontal, to the near-vertical.

This is why Cruzbikes are the best-climbing recumbents on the market. Every other recumbent bicycle currently in production has a fixed boom. There are dozens of makes and models of fixed-boom recumbents. Whether they are rear wheel drive or front wheel drive, pushing or pulling on the handlebar only steers the bike and has no effect on the position of the cranks or pedals, and therefore does not add to power production. Understanding this difference is essential. Sometimes it takes a few hundred miles of riding a Cruzbike for people to experience that “Eureka!” moment when all this technical talk translates into real world performance.

It’s also important to point out that because the feet and legs give input into steering, our DB-FWD bikes can be ridden with the upper body relaxed, when that type of riding is preferred, as during a long straight piece or a relaxing tour. They can even be ridden “no-hands” if you are willing to practice steering the bike entirely with your feet.

Cruzbike has learned through many years of research the best implementation of Dynamic-Boom Front Wheel Drive technology. DB-FWD is how Cruzbike combines the best features of diamond frame road bikes with the best features of fixed-boom recumbent bikes. This technology puts performance and ergonomics in the same bicycle. Once you master Dynamic-Boom FWD, you’ll understand why we have the most fanatically loyal customers of any recumbent bicycle company.

The cool thing is that no matter what kind of riding you do, you’ll benefit from Cruzbike’s years of racing and research. The same core technology found on our record-setting performance bicycles is also found on our utility series.

So what’s the downside? Why isn’t everyone riding a Cruzbike? Actually we think almost everyone should be riding a Cruzbike! We’re just still trying to get the word out. Because engaging the upper body is only one of many advantages, we’ve listed all the features that makes Cruzbike unique in the world of cycling:
