The following table is a convenient reference on the circumference of
several popular bicycle tire sizes. For highest accuracy, measure the
actual circumference directly with a tape measure or similar
technique.
The next three setup items only matter to Cycle Analysts that have
been wired with the throttle over-ride signal connected to the motor
controller. The Direct Plug-in models already have this appropriately
connected, but the Stand Alone and High Current version require
additional wiring for these settings to have any effect.
6.3
Speed Limit
Set the maximum speed beyond which the motor controller will cease
to provide useful output power. The Cycle Analyst will vary the throttle
signal such that the vehicle will continue to cruise at this set point
speed.
6.4
Volts Limit
Program the low voltage rollback point for your battery pack. The
Cycle Analyst will reduce power drawn from the controller in order to
keep the battery voltage from dropping below this limit.
6.5
Max Amps
Set the upper current limit. If the Cycle Analyst senses current above
this value, it will scale down the throttle appropriately to reduce the
amperage draw.
