Description

Cruzbike Recumbent

This is a group for discussions among those who own or are interested in a new type of recumbent, the Cruzbike - a front wheel drive recumbent bicycle with a pivoting boom, or moving bottom bracket.

The Cruzbike is the world’s first commercially available product employing this unusual, yet highly workable format. There are currently four ways to get a Cruzbike:

- It comes as a bolt-on kit; you choose a donor bike and control the cost associated with your recumbent. You can begin inexpensively and upgrade components as your tastes change.

- You can get the laid-back, comfortable Freerider, with its wide handlebars and simple and easy drivetrain for the cruiser experience.

- You can get the Sofrider, which offers the front-wheel-drive advantage in a new-tech, jack-of-all-trades city/tourer.

- You can get the Silvio, a cutting-edge road bike offering aluminum and composite construction, free-running 700c wheels, and 21st century suspension, supplied as a frame kit.

Californian Tom Traylor has a US design patent (D277,744 Feb 26, 1985) for a moving bottom bracket bicycle. The Flevobike and the Chinkara used moving bottom brackets but were really mid steer bikes because of their very low steering head angle. Interestingly, the format of the boneshakers of the 1860s perhaps foreshadowed the modern Cruzbike geometry - minus the comfortable seat, dual suspension, lightweight alloy tubing, rubber tires and gearing!

Most riders are able to take a tour round the block within minutes.

The main strength of the Cruzbike over all other bikes is the uncompromised ergonomics, which translate to many benefits:

o power and efficiency.
o comfort, no danger of saddle induced soft tissue damage.
o passive safety.
o aerodynamically better than a regular bike.
o conditions arms, legs and torso - a great work out.
o fun - one of the most fun bikes you will every ride.

Re: Chainless drives for cruzbike?
... John, That means that the leg length adjustment could hypothetically be used to adjust drive belt tension, right? It would "merely" require a belt of

Re: Chainless drives for cruzbike?
... The distance from BB to axle is critical, unless you introduce some kind of power robbing roller tensioner as in a serpentine belt on a car. Silvio =

Re: Chainless drives for cruzbike?
Not sure if the flex from the suspension would have an adverse effect on the drivetrain. Other than that, yeah looks real nice. Dan

Re: Chainless drives for cruzbike?
... Maybe. I like the technology as well. I see the problem of keeping the belt tensioned as the biggest problem. I see these possible solutions. 1) a free

Chainless drives for cruzbike?
Any gearheads out there who can tell me whether this is possible for a cruzbike? Sounds wonderful.
