ASSIST FUNCTIONS
The system has two assist functions options. The assist function will show in the
display, when selected:
• Assist level 1–5. Select by using the "Up" and "Down" buttons
• "Walk-Assist" function is activated by holding the down button in or by using the
throttle without pedalling. When "Walk assist" is activated then the bike travels with
6 km/h.
"Walk-Assist" is usable if you need to pull the bike up a hill.
Note! " Walk-Assist" is not available on bikes equipped with centre motor and footbrake.
When the throttle is turned then the assist functionality is bypassed and the „Booster
eect“ is activated. Release the throttle and the system returns to assist mode.
Using the throttle is suitable in heavy trac where short bursts of extra power is
required e.g. in situations with overtaking of slow cyclists.
