How and when to change gears
ALWAYS
shift gears while pedaling to avoid cassette damage and broken chains. The shifter controls the
rear derailleur, which moves the chain from one gear to the next. The derailleur can shift gears only
while the chain is moving. The Mid-Drive motor moves the chain when you throttle or pedal, and Dualie
also uses an electronic clutch (gearsensor.com) to shut off the motor during each gear change. It is
designed so you MUST pedal to complete the gear change. Shutting the motor off and relying on
pedaling minimizes the force on the chain and sprockets during gear changes to avoid damage to the
chain or cassette.
WARNING: IF YOU DO NOT PEDAL DURING A GEAR CHANGE, THE MOTOR WILL REACTIVATE AND
PROBABLY BREAK THE CHAIN OR CASSETTE WHEN COMPLETING THE GEAR CHANGE.
When operating under heavy load (power level 4 and 5), temporarily reduce the power level to 3 before
completing the gear change. Avoid changing gears without pedaling or when experiencing heavy load
going up hills or deep snow. Read the section below for more information.
CAUTION: RUNGU WARRANTY DOES NOT COVER DAMAGED/WORN CASSETTES AND BROKEN
CHAINS.
