The joint two-wheel trolley and bicycle is universal joint and the motion of bicycle is not synchronized with trolley and no interference between them. Trolley may fall off due to transient shift of gravity, but the bicycle rider can be free from inter-actions.

Single Wheel trolley is joined with bicycle in two-way movement and is balanced right and left sides and is synchronized with bicycle. The advantage is it is better for poor road condition; however, when the trolley is carrying weight, there is resistance to the shift of gravity and the front wheel is less in holding on road, and it could hinder the control of rider and fall off.

In this design, we stress on the easy conversion between trolley and pull-luggage case. Due to the weight of the trolley, it is very unlikely to slip off, and the safety buckle is designed to prevent slipping. Therefore, please ensure they safety buckle is fitted properly.

We have our authorized dealer to provide service, maintenance and replacing of buckle ring, safety buckles, tire and tube.

Other than check for any loose screw, regular lubricating of the handle joints, no extra maintenance is required. Just keep it clean.
