1. Assist mode select button
• When you turn the power switch to “L” or “R” position, the Twist Freedom provides hybrid
power in the “NORMAL” mode any time the rider pedals.
• If you want to go faster, press the select button to “SPORT” mode.
• Press the select button to “ECO” mode to extend the range.
• When your speed reaches 15 mph, the Twist‘s motor will automatically disengage and cease
assistance. When your speed drops below 15 mph, the motor can assist you once again.
2. Battery level indicator
• Hybrid power is not available when any LED indicator is flashing.
• If one or more LED lamps fail to light up during operation, check to see if the battery is
charged and securely mounted.
4. Self-Test Indicator
The Self-Test system can help determine if two components, the Torque Sensor and the front
wheel Hub Motor, are working properly. To begin the self-test, make sure your Twist Freedom
is resting on its kickstand and the Power Control Switch is in the “OFF” position. Place the
right pedal forward at the “3:00 o’clock” position.
A. Press the Self-Test button and turn the Power Control Switch to either “R” or “L.” One or
more of the middle LED’s on the Left Hand Control should light up.
B. While standing on the right side of the Twist Freedom, steady the bicycle by holding
the saddle with your left hand. Then step down on the right pedal while squeezing the
right brake lever with your right hand. Don’t let the rear wheel move. L1, L2, L3 and L4
should light up in order, depending on the strength and torque you’ve generated while
stepping on the right pedal. The harder you push down on the pedal, the more LED’s (up
to L4) will light up.
C. Next, carefully lift the front of the bicycle off the ground and gently spin the front wheel
forward. L2, L3 and L4 should light up and flash in sequence as the wheel spins. Stop
the wheel from spinning and carefully place it back on the ground.
If the Twist Freedom passed these two tests, you must turn the Power Control Switch to “Off”
and then back to “R” or “L” to ride again.
If the Twist Freedom did NOT pass either or both of these tests, bring it to your Authorized
Giant Dealer for service.
3. Malfunction Indicator
If the LED lights flash while riding, it means that there
is a possible malfunction.
