WHAT IS PEDAL ASSISTANCE?
Pedal assistance is the way an electric bicycle enhances - or magnifies - the effort exerted by
the rider on each pedal stroke. This will allow the rider to travel further or faster while exerting
the same effort, or simply enjoy a more relaxed ride while using less energy and effort.
The amount of assistance provided by the motor (how much a riders effort is magnified) is
indicated by the Pedal Assist System (PAS) level. These iGO eBikes have a 5 level PAS. As a rule,
a lower PAS number will indicate the motor is providing less assistance (ideal for flat roads,
paths, light assistance) and a higher PAS number will indicate an increased assistance from the
motor (for when you are riding up a steep incline, into a strong headwind, carrying a heavy load,
or just want a more relaxing ride).
If the assistance is set to '0' all assistance will be disengage when pedaling, allowing the bike
to be ridden as a standard non electric bicycle. The lights and cyclocomputer functions will
continue to function but the motion of the bicycle will rely solely on the riders manual effort.
(For your safety iGO electric bicycles default to PAS level 0 each time the bike is powered on
for safe mounting and dismounting.)
Note : the throttle will also be inactive when assistance is set to '0'.
Be aware that the motor will draw more power from the battery as more assistance
is used. Extending the range of the battery can be achieved by reducing the intensity
of assist used. Understanding the efficient use of bikes gears to complement
pedal assist levels will allow for a smoother riding experience, can extend the
range of the battery and has an added benefit of exerting less stress on bike
components allowing them to last longer before requiring replacement.
Assistance will engage in different ways depending on the type of sensor being used.
ABOUT CADENCE SENSING
Pedal assist with cadence sensor allows the rider to have assistance as soon as the rider
begins to pedal and for as long as the rider continues to pedal. The iGO cadence sensor is
located in the bottom bracket, weather-proof and away from potential harm or tampering. It
uses up to 32 optic sensor points to let the system know when the rider has started or stopped
pedaling making it extremely efficient and fluid in the system's ability to deliver assistance.
ABOUT TORQUE SENSING
Pedal assist with a torque sensor enables the system to provide measured
assistance based on the rider's effort. The sensor uses pressure and strain gauges
to measure the effort that the rider is putting into the pedals and provides
the required assistance to ensure a smooth and comfortable balance. The
more effort the rider puts into the pedals, the more the system assists.
ABOUT WALK ASSIST
USE CAUTION WHEN ENGAGING THIS FEATURE AND ENSURE THAT YOU ARE
IN CONTROL OF THE BICYCLE BEFORE OPERATING WALK MODE
Walk Assist mode enables the bike to "walk" beside the rider at 6km/h. This feature is practical
for walking the bike up-hill, when guiding on to a bike rack or carrier as well as when advancing
with the bike over any surface that may be difficult to pull/push the bike through (mud, snow,
sand, etc).
Release the MINUS (-) button to disengage walk assist at any time. As a further safety measure
pulling on either brake lever will trigger the power-cut off switch which will disengage power
and walk assist.
THROTTLE
Throttle thumb controls on iGO eBikes function when in Class 2 and 3, and are fully
disabled in Class 1. Pushing down on the throttle will provide an immediate boost
of acceleration to the bike (whether pedaling or not). The bicycle will continue to
accelerate until the throttle is released or when the bicycle reaches its maximum
assist speed limit. If the throttle is held down while at maximum assist speed the
bicycle will continue to cruise and maintain speed limited power, but no additional
acceleration will occur in assisted pedaling until the speed drops below the limit.
For rider safety the throttle is inactive when assistance is set to '0'.
THROTTLE
Note : Sudden bursts of acceleration - especially from a stationary position - can exert
extra stress on components. Selecting the correct gear and pedaling to build up momentum
before engaging the throttle to accelerate will extend the life of your bicycle components.
