8. The test should be performed according to the following order:
a) Put the electrically power assisted bicycle for test on the test machine.

b) Put the load of 60kg on the saddle.
c) Set the speed, the speed-changing position of the electrically power assisted

bicycle in Table 1, and set the driving impedance.
d) Please use the external motor to drive the crank of the electrically power

assisted bicycle to generate the roller surface speed in Table 1 according to the
type of the test method. The variation range of the revolution speed of the

crank is ±2%.
e) Please test the driving distance from the electrically power assisted bicycle’s

crank starting to revolve to the electrically power assisted bicycle’s assistant
force stopping (Note 2); the unit for resting the endurance is km. Please round

off to the 2 nd decimal place.
Note (2): the stopping of the assistant force means that the force output current

of the assistant motor is cut and the electrically power assisted bicycle
cannot be assisted by the assistant motor even if the electrically

power assisted bicycle is driving.
