BATTERY GAUGES
When the throttle or sensor is engaged (powering the motor) 
and the bicycle is in motion, the LED’s on the battery gauge (on 
the throttle or separate unit) indicate instantaneous line voltage 
as measured at the battery terminals -- and not the available 
energy in the battery pack. 
The line voltage will fl uctuate depending on the instantaneous 
load that the motor is under. For example, when starting out 
from a dead stop, or going up a steep hill, the motor will be 
under a high load and may show a reduced number of LED's 
(some throttles depending on the color of the LED’s will show 
the “Yellow” or even “Red” LED). 
When the throttle is disengaged (i.e. no power to the motor due 
to the bicycle being stationary or coasting) the LED’s on the 
throttle will indicate the voltage of the battery pack. The voltage 
of the battery pack will rise when no load is on the motor. The 
best indication of how much battery life is remaining is to check 
the throttle LED’s, after reaching cruising speed, on a fl at 
straight road as this will allow the battery voltage to stabilize 
and give a much more accurate reading.

BATTERY GAUGE WITH POWER ADJUSTER
This unit is featured on the Enlightened series of bicycles. Not 
only does it act like a battery gauge but it also enables the rider 
to vary the level of power assistance (1 LED = least amount 
of power assistance, 5 LED's = maximum amount of power 
assistance).
Press the "+" button to increase the amount of power 
assistance (Note that this will also decrease the range of the 
bicycle because more battery power is being used).
Press the "-" to decrease the amount of the power assistance 
(Note that this will also increase the range of the bicycle 
because less battery power is being used).
