There are two different Boost Modes on Optibikes, FAST and SLOW. These are changed by toggling the MODE switch on the headlight. The FAST and SLOW Boost Modes affect the sensitivity of the Boost Mode.Some riders find the normal, Fast Boost, is too active with their riding style, so they use the less sensitive, Slow Boost Mode.
What is Boost Mode?
Boost Mode is the amount of acceleration the Optibike has when shifting gears or accelerating from a stop. Some riders find their bikes entering Boost Mode too often. The Slow Boost Mode is less sensitive, making it harder to enter, and will not offer as much acceleration during shifting.
The dual Boost Mode is available on Firmware Versions 505 and higher. Version 505 was installed on bikes shipped in November 2008 and after.
How to Adjust Boost Mode
Boost Mode is toggled by rapidly switching between FAST and ECO modes two times.
Example:Switch is in FAST Mode. Rapidly switch to ECO, then FAST, then ECOthenFAST. LED will flash to indicate which Boost Mode has been entered. (See below)
When Fast Boost Mode is entered, the Green and Yellow LED will flash quickly for one second and then the normal gas gauge LED will display.
When Slow Boost Mode is entered, all three LED will flash quickly for one second, and then the normal gas gauge LED will display.
If your bike does not exhibit the flashing LED, after toggling, it does not have the dual Boost Mode feature.
