Bicycle suspension with shock strut

A bicycle comprises a main frame defining a spring mount, a pivot mount, and a reinforcing strut substantially directly connecting the spring mount to the pivot mount. The reinforcing strut is asymmetrically positioned on one side of the central plane. A rear frame is movable relative to the main frame, a pivot link couples the main frame to the rear frame, and a spring assembly couples a portion of the pivot link to the main frame. The pivot link comprises a left link member, a right link member, and a link bridge connecting the left link member to the right link member. Preferably, the link bridge is positioned rearward of a seat tube on the main frame. The rear frame comprises a seatstay bridge connecting a left and right seatstays. The main frame can support a crank assembly having a chainring offset from the central plane on the same side as the reinforcing strut.

BICYCLE ELECTRIC SUSPENSION
20200148299 · 2020-05-14 · ·

A bicycle electric suspension comprises a first tube, a second tube, a positioning structure, an electric positioning actuator, and a telescopic controller. The first tube has a center axis. The second tube is telescopically received in the first tube. The positioning structure is configured to relatively position the first tube and the second tube in a telescopic direction extending along the center axis of the first tube. The electric positioning actuator is configured to actuate the positioning structure. The telescopic controller has a control mode in which the telescopic controller controls the electric positioning actuator to actuate the positioning structure, and a sleep mode in which power consumption of the telescopic controller is lower than power consumption of the telescopic controller in the control mode.

System and method for adjusting spring rate of a coil spring in a bike suspension
10611428 · 2020-04-07 ·

A system for easily adjusting spring rate of a rear shock for mountain bikes or motorcycles without changing an actual overall spring length. The system may include a coil spring a body sized and structured to engage with the coil spring. The spring rate may be adjusted by selectively placing the body between adjacent coils of the spring to deactivate up to one spring coil adjacent the end of the spring.

Smart fluid damper

A smart fluid damper includes a damper body defining a cavity with smart fluid. A piston head is disposed within the cavity and is slidingly displaceable. A flow control element is disposed within the cavity. The flow control element includes a main body having a central core, and an outer housing that surrounds the main body and is spaced apart therefrom to define a fluid passage between the main body and the outer housing. The fluid passage extends axially through the main body to permit fluid flow therethrough. The central core includes an energizable coil operable to apply a field. A plurality of field barriers are provided, each operable to locally block the field generated by the energizable coil such that the field cannot pass directly therethrough. The field barriers are configured to focus the field within the fluid passage.

A trailing link, multi-link, suspension assembly for a bicycle having improved stability includes a first arm having a first arm fixed pivot and a first arm shock pivot. A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has a first shock mount and a second shock mount. A wheel carrier has a wheel carrier first pivot and a wheel carrier second pivot spaced apart from one another, and a wheel mount that is adapted to be connected to a wheel. A control link has a control link floating pivot and a control link fixed pivot, the control link floating pivot being pivotably connected to the wheel carrier second pivot, and the control link fixed pivot being pivotably connected to the first arm control pivot. A mechanical trail distance increases as the suspension assembly compresses relative to a fully extended state.
