6th gear, but for the best acceleration and performance it’s a good idea to start in a low gear and shift up as
you gain speed.
HILLS
If your objective is not to reach maximum speed but to effciently ride up a hill, you should consider that the
system will give you more torque when in a lower gear. Shift down when you encounter a steep hill; the
motor will be put under less strain, and your battery’s range will increase.
EXTENDING THE LIFE OF YOUR DRIVETRAIN
A center drive motor can put extra stress on drivetrain components such as the chain, cassette, derailleur,
and derailleur hanger if not ridden with care. The best way to avoid excess wear on the drivetrain is to avoid
shifting under load.
Shifting under load means to shift the derailleur while the motor or rider is pulling hard on the chain. The
extra chain tension keeps the derailleur from shifting effectively and can cause damage to the drivetrain.
To shift properly, make sure you ease up (on both the throttle and pedals) just before and just after you
shift. Let the chain drop into place fully before you start pedaling or throttling hard again.
WARNING
Shifting under load can cause the chain or other drivetrain components to break suddenly, leading to a
crash.
