Velotron is the ONLY
commercially available laboratory-accurate
electronic bicycle ergometer which permits the
use of the rider’s own bicycle frame. Since it
is generally acknowledged that testing on a
rider’s own bike provides the most meaningful
test results, it follows that Velotron has an
important advantage over other ergometers.
Velotron also has other important advantages for
sports science applications. Its price below
$6000 is half the cost of the Lode Ergometer and
only a third that of the SRM Ergometer. This
price advantage comes with no sacrifice in
accuracy, durability, or serviceability. And its
maximum load capability of 2000Watts exceeds the
physical capabilities of all but a handful of
track champions.
The accuracy of each Velotron is established by
reference to RacerMate’s in-house laboratory
bicycle dynamometer which can be read to an
accuracy of 1%. Of perhaps greater importance is
the fact that Velotron’s repeatability is in a
class by itself – better than 0.01%! The system
is permanently calibrated at the factory, and
there is nothing inherent in the design which
would lead to calibration drift in the field.
The calibration can be checked before each use
with Accuwatt, a proprietary calibration
verification procedure (Patent Pending) which
takes less than 10 seconds.
Velotron durability is expected to exceed that
of CompuTrainer, which in commercial
applications has reached 125,000 race cycles
without failure with a service life of 10 years
or more. Occasional cleaning and oiling of the
drive chain is the only routine maintenance step
required.
A modular design insures easy serviceability.
The eddy current brake/electronics sub-assembly
is housed in a single aluminum enclosure which
can be easily removed and exchanged for a
factory replacement so that downtime is
essentially eliminated. The Velotron system
software is Windows PC based and highly
versatile. Testing and training protocols can be
established either in terms of watts and time,
or distance and grade. The results are displayed
instantaneously as well as in averages and
maximum values for each performance variable.
Variables displayed and recorded include watts,
heartrate, speed, cadence, distance, SpinScan
number, left/right leg power split, and
PulsePower number (watts per heartbeat per
pound). |
