Abstract
The collapsible bicycle trailer comprises a chassis and wheels. The chassis includes an upper frame assembly having a front end pivotally connected to the front end of a lower frame assembly and a back frame unit including a pair of oppositely disposed back frame members- Each back frame member has an upper end pivotally connected to the rear end of the upper frame assembly and a lower end removably securable to the rear end of the lower frame assembly. The back frame unit is pivotable around the upper end of the back frame members between a folded position, where the upper frame assembly is rotated towards the lower frame assembly for folding the chassis into a compact position, and an opened position, where the lower end of each of the back frame members is secured to the lower frame assembly for opening and keeping the chassis into an extended position.
