Using Derailleur (Gear) Shifters
Depending on the Dualie or XR package you purchased you have one of two different trigger-style gear
shifters common to mountain bicycles. You use them to change gears and optimize your Dualie riding
experience. Selecting the right gear lets you apply the appropriate power for the appropriate terrain.
The shifters let you change the gear ratio between the motor and the rear wheel to best leverage the
power coming from the motor regardless the power level. Like the transmission in a car, being in the
wrong gear can cause the car to stall or use excessive energy to maintain speed. The same holds true
with your Dualie.
Each Dualie has 9 gears
–
first gear is the largest sprocket on the rear wheel; ninth uses the smallest.
First gear has the lowest gear ratio between the motor and the rear wheel. First gear is used for hill
climbing or crossing the most difficult soft terrain. Ninth gear has the highest gear ratio;
it’s used for
cruising on flat roads to achieve the highest speed.
Changing gears with the BOX Prime 9 system
If you have the derailleur pictured below, your Dualie is equipped with the BOX Prime 9 system.
