A vehicle frame's coupler structure that connects separable frames for easy assembly and disassembly, at a low cost. Further, the couple structure can provide a vehicle that is easy to operate, without affecting the user when in use. The vehicle frame's coupler structure includes combining a Front-side Coupler Inner Face (8) with Rear-side Coupler Inner Face (9), and after making sure all components of (8) and (9) are in place (no protruding edges, etc.), and using Bolt (15) to fasten Part (6) with Part (7). The end result is the coupler system of the vehicle.

A drive apparatus for an electric bicycle with an electric motor, an energy storage unit for supplying the electric motor with electrical energy, and a carrier at which the energy storage unit is releasably held, wherein a first plug connector is provided at the energy storage unit and a second plug connector is provided at the carrier which plug connector is connected to the first plug connector to connect the energy storage unit to the electric motor. The first plug connector is mounted in a pivotable manner at the carrier about a first pivot axis.

An adaptor bar includes a retractable tube unit. Two end parts are respectively connected to two respective ends of the tube unit. Two C-shaped hooks are respectively fixed to the two ends of the tube unit. Each hook includes a first connection portion. Two plates are respectively connected to the two end parts. Each plate includes a first section, a second section and a third section. The second section is formed inclinedly between the first and third sections. The third section of each plate is fixed to the end part corresponding thereto. The first section of each plate is removably engaged with the first connection portion of the hook by sliding the end part. The first section includes a first recess and a second recess. The second recess is located close to the second section and includes a recessed reinforcement which reinforces a portion between the first and second sections.

The invention relates to a bicycle frame (1) with a remote-controlled shock absorber (2) connected to the frame (1). The shock absorber (2) comprises two dials (3, 4) for adjusting the compression and rebound. The frame (1) is characterised in that it comprises a depression (9; 25) communicated with the outside of the frame (1) and provided with a window (12; 28) that communicates the depression (9; 25) with an inner part (8b; 18b) of the frame (1). An actuator element (7) for adjusting the compression dial (3) extends from the outside of the frame (1) towards the window (12; 28) passing through the inner part (8b; 18b) of the frame (1). The invention improves the integration of the rear suspension of the bicycle while simultaneously allows for easy adjustment of the compression dial (3) and the rebound dial (4).

A method for forming a bicycle frame component made of thermoplastic composite laminates has: a shell forming step: manufacturing multiple shells by compression molding; an overlapping step: overlapping two corresponding connecting margins of each two of the multiple shells to form an overlapping section of the two of the multiple shells and deploying a supporting unit within the multiple shells for supporting; a hot compressing connection step: heating and compressing the multiple shells to diffuse polymers of the multiple shells and to turn the multiple overlapping sections into multiple fusion areas for connection; a supporting unit removal step: removing the supporting unit disposed within the bicycle frame component.
