Zero DS 2012, Owner'S Manual

Page: 14 / 120

1-11
Average motorcycle range is calculated using an
industry standardized formula. The range is separated
into two separate specifications: “City (EPA UDDS)”
Environmental Protection Agency (EPA) Universal
Dynamometer Driving Schedule (UDDS) and
“Highway.” The City (EPA UDDS) range is a U.S.
federal test procedure to give an estimate on how
many miles an electric vehicle will go on a single
charge. The highway range is to provide the rider an
estimate of what you can expect to achieve when
using the motorcycle for highway commuting. This
range takes into account the distanced traveled on
city roads getting to and from the highway as well as
the distance spent in highway congestion. The
average highway commute is made up of 50% steady
highway speed riding and 50% city- like riding. See
technical specification charts on page 1-6 through
1-10 for these ranges.
Optimizing Your Range By Adapting
Your Riding Style
•
Apply the throttle slowly and try to match the
motorcycle’s acceleration with your throttle
position.
•
Hard acceleration will decrease your range.
•
The Zero S/DS has the ability to start, from a
standstill, up a steep 13% grade when fully
loaded. It is not recommended that you stop on
a grade of more than 13% with a fully loaded
motorcycle.
•
Example: If 108 km/h (67 mph) can be reached at
100% throttle, 75% throttle will give you about 89-
95 km/h (55-59 mph) (a 25% energy savings for
an approximate 12% speed loss).
•
Coasting whenever possible makes a significant
difference. The regenerative braking system on
deceleration takes some of the energy from the
motor and turns it back into electrical energy. This
energy is then stored back into the power pack.
•
Plan ahead for decelerations and coast whenever
possible. For example, do not rush to traffic
signals.
