4.4.2 Parking brakes and parking stability for Single lane

4.4.2.1 General

The single lane design of the CARGO BIKE, during the parking and unloading of the
vehicle, the parking device is used to stabilize the body, and the parking device is

required to carry the weight of the cargo while maintaining stability, most of CARGO
BIKE for single lane were set the two points and one wheel to touch ground, so it is
necessary to ensure that the slope is still stable in the parking state.

4.4.2.2 Requirement

When tested by the method described in 4.4.2.3, the positive force of any landing
support point must not be zero, to ensure that the slope is still stable in the parking

state.

4.4.2.3 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 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, the
positive force of any ground support point should not be zero.
