4.4 Parking brakes and parking stability

4.4.1 Parking brakes and parking stability for Multi-lane

4.4.1.1 General

For multi-lane design of the CARGO BIKE, during the parking and unloading of the
vehicle, the wheel is tightened to stabilize the vehicle body. Therefore, it is necessary
to ensure that the slope is stable in the parking state.

4.4.1.2 Requirement

When tested by the method described in 4.4.1.3, No wheel rolling or relative

movement of the tire and the ground may cause the vehicle to move in the forward
and backward direction. The positive force of any landing support point must not be
zero.

4.4.1.3 Test method

Place the test CARGO BIKE on a level and adjustable pitch platform with the wheels
in the same direction of travel. Adjust the parking (brake) device to make its parking
function work and maximize its effectiveness. The maximum cargo capacity claimed

by the operator is placed in the cargo position. Other loading weights: 6.75 kg at
each end of the handlebar, 18 kg for each pedal, and 36 kg for the seat post.

Adjust the angle of the front, rear, left and right of the test platform from the
horizontal state to 10 degrees (with the ground friction coefficient: 0.75~1), and tilt
at an angle of 10 degrees at the front, rear, left and right tilt angles. In the state,

observe whether the CARGO BIKE moves in the front-rear direction, and whether the
positive force of any ground support point should not be zero.
