THE BEHEMOTH
BEHEMOTH, Big Electronic Human-Energized Machine ...Only Too Heavy
(1983-1991), L2003.2001, Loaned by
Steve Roberts
After speaking at a Museum lecture on Sept 7, 2000, Steve Roberts presented
BEHEMOTH to The Computer
Museum History Center as a long-term loan
In the early 1980s, feeling trapped in his suburban lifestyle, Steve
Roberts began to reevaluate his life. Roberts, a
freelance technical writer who had published articles in magazines such as
Byte, decided to tour the country on a
recumbent bicycle of his own design, the Winnebiko. During his trip,
Roberts made his living publishing stories
and writing a book as he went along, using his on-board Radio Shack TRS-80
Model 100 and a CompuServe
account to email his stories to publishers.
After redesigning the bike (as Winnebiko II), Roberts went off in an
entirely different direction, devising
BEHEMOTH (Big Electronic Human-Energized Machine ...Only Too Heavy): a
580pound, 105-speed recumbent
bicycle with a four-foot yellow trailer solar panel array that allowed the
incorporation of many more technologies
than on previous bikes. Roberts envisioned a project where a "computer and
communication tools rendered
physical location irrelevant." BEHEMOTH sported antennas for communication
over various amateur and public
radio networks, several networked computers (including an Apple Macintosh
and an Intel 386-based laptop), a
special keypad on each bicycle handle to allow typing, and a security
system that would
alert police if the vehicle were disturbed. The helmet is perhaps the most
futuristic-looking part of BEHEMOTH,
with its heads-up display, motion sensors for cursor control, lights, fluid
heat exchanger to keep the head cool,
and audio system. A complete feature list is shown below.
Roberts logged over 17,000 miles on BEHEMOTH and gave hundreds of radio,
television, and print interviews
over the several years he was on the road. This wide exposure points to
BEHEMOTH as an important milestone in
the integration of technologies for recreational use, as well as a highly
visible artifact of early wireless mobile
networking. Roberts retired BEHEMOTH to begin a new project called the
Microship.
