A hydraulic valve having a body defining an inlet and an outlet. A motor is supported by the body and operates a shaft extending through an interior of the body, the shaft terminating in a gate. A spring is supported within the housing and influences the gate in an open position to permit fluid flow between the inlet and outlet. Upon the occurrence of a pressure differential resulting from a fluid flow through the inlet exceeding a biasing force of the spring, the gate is caused to displace against a valve seat communicating the inlet with the outlet in order to interrupt fluid flow in a standby mode and to define a closed position. The motor operates in a further throttling mode to linearly and incrementally displace the gate between the open and closed positions said outlet and in order to adjust flow through the outlet.

What is provided is a cargo bicycle apparatus and a kit for converting an existing bicycle into a cargo bicycle. The cargo bicycle apparatus comprises a cargo attachment that easily attaches and detaches from an existing bicycle to make the existing bicycle more utilitarian and functional. The cargo attachment connects with the existing bicycle in a way that prevents damage or permanent modification to the existing bicycle. Since no specialized tools or mechanical skills are required in the assembly of the cargo bicycle apparatus, the cargo attachment provides the operator with greater convenience and flexibility for converting an existing bicycle into a cargo bicycle apparatus. In addition, the cargo attachment is configured to automatically adjust to the geometry of nearly all existing bicycles without having to modify the geometry of the cargo attachment to match the geometry of a particular bicycle.

Bicycle conversion kit and cargo bicycle apparatus

An apparatus is provided for bicycles to make them more utilitarian and functional. The attachment is easily attached, and potentially attached without damage or significant modification to the bicycle. The apparatus includes a frame member attached to the bottom bracket portion of the existing bicycle, and a gimbal attached to the fork of the existing bicycle in place of the original front tire. The apparatus is steerable using the handle bars and fork on the existing bicycle frame, and is configured for stability when cornering. The apparatus includes a cargo carrier located in front of the cycler where it is easy to see, while maintaining a stable center of gravity and also an ability to lean into corners for cornering stability. Variations include one or two front wheels, and one or two steering drive links. Also, the apparatus is a flexible design providing multiple potential utilitarian uses.
