A frame for a bicycle is disclosed. The bicycle also has a drivetrain, and a plurality of wheels. The frame has a main frame portion, a rear frame portion, a pair of shock absorber mounts, and a pair of linkages. The first linkage is pivotably connected to the rear frame portion and pivotably connected to the main frame portion. The second linkage is also pivotably connected to the rear frame portion and to the main frame portion and further provides a mounting for a drivetrain component such as an idler or bottom bracket. Both linkages also rotate in a counter direction relative to the rotation of the rear frame portion.

Disclosed herein are examples of motive power sources suitable to power a two-wheeled vehicle. The vehicle may include a suspension linkage and a suspended body. In some examples, the motive power source may include a housing with a boss extending therefrom. The boss may include a first securement structure. The securement structure may include an instantaneous velocity center of the suspension linkage when coupled to the two wheeled vehicle. In some examples, a second securement structure is formed in the suspended body, a bottom link forms a portion of the suspension linkage, the bottom link includes a third securement structure, and an axle is coupled to the first, second, and third apertures. In some examples, the first, second, and third apertures are concentric with the axle.

A rear wheel suspension device includes: a swing arm swingably supported with respect to a vehicle body frame, the swing arm rotatably supporting a rear wheel; a rear cushion configured to be extended and contracted in accordance with swing of the swing arm; a cushion lever coupled to a lower end portion of the rear cushion; a cushion rod coupling the cushion lever and the swing arm; and an accumulator storing a working fluid that extends and contracts the cushion rod. A vehicle height is adjusted by displacement of the swing arm in accordance with extension and contraction of the cushion rod. The accumulator is positioned on a lower side of a swing shaft of the swing arm.
