Electric Motorcycle Speed Record Demonstrates BOLDER TMF Technology

Electric Motorcycle Quarter-Mile Speed Record Demonstrates High Power Performance of BOLDER TMF(R) Technology

    GOLDEN, Co. - BOLDER Technologies Corporation announced that an electric 
motorcycle called the "Killa-Cycle," powered by BOLDER's patented Thin Metal 
Film technology, recently set a new National Electric Drag Racing Association 
speed record, according to Roger Warren, chairman, president and CEO of BOLDER.

    The Killa-Cycle, driven by Kerry Hogan and owned by Bill Dube, completed a
quarter-mile race in 10.539 seconds at Speedworld Motorplex, a National Hot
Rod Association (NHRA) member track located in Phoenix, Arizona.  The totally
electric motorcycle was powered by an enhanced battery system comprised of 456
TMF cells, interconnected in such a way to supply a peak power of about a
third of a million watts during a quarter- mile run.   The TMF cells that
power the Killa-Cycle are the same cells that provide starting power for the
SecureStart(TM) emergency engine jump start products that are currently
available through Sears, Target, and other major retail stores.  Technical
information on the Killa-Cycle can be found on the website
http://www.killacycle.com .

    Warren stated, "We are very excited about the Killa-Cycle and the National
Electric Drag Race Association's promotion of TMF technology.  We are pleased
that TMF technology is becoming the baseline for electric drag race vehicles.
The Killa-Cycle has provided an excellent avenue to highlight the enabling
performance capability and superior attributes of our TMF technology - packing
very high power into a small compact space and releasing this high power very
quickly."

    BOLDER Technologies Corporation, headquartered in Golden, Colorado,
manufactures and markets advanced, high-power rechargeable batteries based on
its patented Thin Metal Film (TMF(R)) technology. The Company is developing
and commercializing consumer and OEM battery products with the TMF technology,
including the SecureStart(TM) Portable Jump Starter, that use proven lead-acid
electrochemistry in a proprietary configuration with a higher power density
than any commercially available rechargeable battery.  The TMF technology
offers numerous advantages over existing batteries for current and future
applications, including near-term opportunities in the marine and auto after
markets for 12V batteries.  

    BOLDER's TMF technology also has possible future applications in the
pending auto industry conversion from 12V to 36V systems, both directly
through vendor sales and indirectly through a license agreement with Johnson
Controls (JCI).  JCI uses the TMF technology for its Inspira(R) battery system
for 42V architectures.
