c)While pedalling, ride steadily to reach a speed equal to 1,25 times (if possible by
design) the maximum assistance speed as declared by the manufacturer.

d)Verify that the noted value in b) is the no load current point.

4.2.12 Start-up assistance mode
4.2.12.1 Requirements
An EPAC can be equipped with a start-up assistance mode that operates up to a

maximum speed of 6 km/h.
This mode shall be activated by the voluntary and maintained action of the user
either when riding without pedalling or when the user is pushing the cycle.

4.2.12.2 Test method

4.2.12.2.1 Test conditions

a) The test may be performed either on a test track, a test bench or on a stand that
keeps the motor driven wheel free of the ground.
b) The speed-measuring device shall have the following characteristics:
1) accuracy: ± 2 %;

2) resolution: 0,1 km/h.
c) The ambient temperature shall be between 5 °C and 35 °C.
d) Maximum wind speed: 3 m/s.

e) The battery shall be fully charged according to the manufacturer's instructions

4.2.12.2.2 Test procedure

a) Pre-condition the EPAC by running it for 5 min at 80 % of the maximum
assistance speed as declared by the manufacturer, then stop.

b) Activate the start-up assistance mode and verify that the speed increases up to
6 km/h maximum designed speed or lower value.

c) Verify that the speed reduces progressively to 0 km/h when the start-up
assistance mode is deactivated and that the current drops to a value equal to or

less than the no load current point when the motor driven wheel freewheels.

d) Activate the start-up assistance mode and maintain it for 1 min.

e) Verify that speed is equal to or less than 6 km/h

f) Verify that the start-up assistance mode is activated only when the actuation of
the device to initiate it is maintained.
