Dynamic strength test on fully assembled bicycle

J.1 Requirement

When tested by the method described in J.2, there should be no system or
component failure and no loosening or misalignment of the saddle, handlebar,

controls, lighting equipment, or reflectors, and the function of electric power assisted
should be normal.

J.2 Machine test

Mount a fully assembled electric power assisted bicycle on a test machine. The
following weights should be applied:

－one 36 kg weight with a pin for insertion in the seat-post and divided into two
halves to be hung, one on each side;

－two 18 kg weights with fixtures for attaching them to the cranks in place of the

pedals;
－two 6,75 kg weights with fixtures for attaching them to each side of the handlebar;

－one 10 kg, 18 kg, or 25 kg weight with the dimensions 240 mm × 240 mm on the
luggage carrier.

－Electric power assisted bicycle should include controllers, motors, batteries and
other assisted power system.

An example of a test arrangement is shown in Figure J.1, in which the Electric power
assisted bicycle is mounted on two drums. The diameter of the drums should be in a

range from 500 mm to 1 000 mm, and the slots should have a width of 50 mm ± 2,5
mm, a thickness of 10 mm ± 0,25 mm, and 45° chamfered edges of half their
thickness. The circumferential spacing between the centrelines of two consecutive
slots should be not less than 400 mm.

Rotate the drums to give a linear surface speed of 8 km/h (±10 %) for a period of 6 h.

The tyres of the bicycle should be inflated to the maximum inflation pressure.
