NOTES
• When the e-bike system is switched on and a support level is selected, the e-bike
system is activated as soon as you start pedaling.
• The assist support modes aect how much support the assist system delivers based
on your pedaling input.
• Generally, more support provides faster acceleration and easier climbing at the
expense of shorter range. Lower assist levels that provide less support result in longer
battery run times, longer range, and more control in situations where traction is limited.
• If your e-bike is equipped with gears, change gears appropriately to get, in addition
to adjusting assist modes, the most use out of your battery.
• The e-bike drive output only supports to a maximum speed of 25 km/h (15.5 mph);
as soon as you have reached this speed limit, the e-bike suspends the riding support,
then automatically reactivates when your speed comes below this.
⚠ WARNING
It is strongly advised to ride away in a straight line with a low support level selected.
Never select assistance level 2 or 3 while maneuvering or riding away in a sharp
corner. The powerful reaction of the motor might cause the e-bike to surge forward into
a sharp turn resulting in loss of balance.
5.5. Charge level indicator
