CONCORD, Mass.—(BUSINESS WIRE)—November 26, 2007— Imagine cycling 50 miles, stopping at a convenience store to refuel, and having no way to get inside. This frustrating scenario, repeated ad nauseum, prompted a trio of avid handcyclists - whose machines were too big to get into the store and whose legs couldn't carry them - to create their own solution - the morphing handcycle, designed entirely in SolidWorks(R) 3D CAD software.
In stretched-out lowrider position, it's a traditional handcycle -
stable and aerodynamic, ready to ride as far as any bicycle at roughly
the same speed. Morphed into high-rider position, it has a
wheelchair's agility for navigating doorways and aisles. It also puts
the user at eye level with standing persons - optimal for picking
items from store shelves.
Rory McCarthy (right), Bill Warner, and Graham Butler designed the
machine under the aegis of McCarthy and Warner's nonprofit Move With
Freedom, based in Cambridge, Mass. "Any CAD software lets you design
and assemble parts," said McCarthy, who has cycled the globe on a
handcycle. "SolidWorks software, however, made a big impact on our
design by letting us experience the assembly in motion. Graham, our
product designer and SolidWorks expert, was able to turn my high-level
designs into detailed virtual prototypes. This was critical in
conceiving and refining the four-bar linkage and the crankset/steering
assembly, which needs to turn smoothly in both low- and high-riding
positions. As a result, we've got a highly functioning physical
prototype ready for user feedback."
The morphing handcycle involves no electronics. To morph into
high-riding position, the rider sets the brake and rolls the rear
wheels forward, as with a wheelchair. The 24-speed cycle employs twin
mechanical gas shocks, specified for the rider's weight, that assist
in the lift, enabling the user to switch to high-riding mode with
single-hand force. Other components are standard bike parts.
McCarthy is a longtime electrical engineering designer who
embraced SolidWorks from the onset of the project two years ago. "I'm
a longtime AutoCAD(R) software user, yet SolidWorks immediately proved
to be a great tool and a more intuitive and logical way of designing.
When it's time to build, most of the questions have already been
answered. We took care of the trial and error on the screen."
The morphing handcycle embodies Move With Freedom's commitment to
easy and natural mobility for all. Rather than commercially protect it
with patents, the company intends to donate the finished design to the
public domain so that others can customize it for their own needs.
Move With Freedom's next project is a morphing wheelchair, which would
make it easy for users to surmount a curb without risking a backward
"We've seen many instances where SolidWorks improves business
performance," said Rainer Gawlick, vice president of worldwide
marketing. "It's inspiring in this case to see improved human
performance and a direct positive impact on quality of life."
Move With Freedom's founding supporters include authorized
SolidWorks reseller CAPINC (Computer-Aided Products). Through its
"Engineers in Action" community involvement program, CAPINC has
provided Move With Freedom additional grants for ongoing training,
service, and support.
