Qwic PREMIUM Series Manual page 59

Note that under different conditions the range
i
can differ strongly. Our tests have been carried
out in one single test drive, on flat terrain, at
temperatures of approximately 20 degrees
Centigrade, at an average speed of 20 km/h
and an approximate total weight of 75kg.
Why is there such a big difference between the
minimum and maximum advised range?
As indicated, the main factor that influences range
is the chosen power assistance mode. Especially the
Bafang mid-drive motor, which powers the Premium
MN8 and MN8c, has a very energy efficient lowest
power level. This results in a long range. At higher
power levels the range decreases fast, as can be seen

from the graph below.
Low
Level of assistance
Besides the power assistance level there are more
factors that influence the range, such as:
• Total weight (bike + cyclist + luggage)
• Total resistance or drag (wind, tire pressure, gears,
road condition and altitude variation)
• Outside temperature
• Battery age (the capacity of a battery decreases
with time, about 5-10% per year)
•
What can I do to increase the range?
Many factors which influence the range are
incontrollable. However, there are a few tips for the
trained cyclist to increase their distance travelled on a
single battery charge.
• Make sure the tire pressure is correct
Hoog
An under inflated tire results in a lot of drag which
diminished the efficiency of the motor strongly.
Make sure the tire is inflated close to the maximum
indicated pressure (see side of the tire wall)
• Change gears in time
With the powerful motor assistance it almost feels
unnecessary, but be aware that changing your
gears in time can make a major difference in the
effective range of your battery charge. Especially
taking off at a traffic light in the wrong gear can
High
cost a lot of extra energy.
