Various embodiments provide for a bike-supported communication network that manages and facilitates communications between components of an electric bicycle and a wireless network. In some embodiments, the systems and methods provide a lock assembly for an electric bicycle, having a lock module that is configured to lock a rear wheel of the electric bicycle and a communication module that facilitates wireless communications between the electric bicycle and a communications network.

A seat that includes an upper surface, a lower surface, one or more pressure sensors communicatively coupled to a controller, and a plurality of artificial muscles disposed between the upper surface and the lower surface. Each of the plurality of artificial muscles is communicatively coupled to the controller. Each of the plurality of artificial muscles includes a housing having an electrode region and an expandable fluid region, a dielectric fluid housed within the housing, and an electrode pair positioned in the electrode region of the housing. The electrode pair is actuatable between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region.

An auxiliary wheel mechanism 151 of a two-wheeled vehicle disclosed herein includes an auxiliary wheel 1, a saddle support member 7, a transmission member 9, and an auxiliary wheel urging member 23. The auxiliary wheel 1 is supported by a vehicle body 11 to be located on a side of a rear wheel 13 and to be movable between a retracted position retracted from a road surface 17 and an operative position where the vehicle body 11 is supported against the road surface 17 so as not to tilt. The saddle support member 7 is provided on the vehicle body 11 and supports a saddle 27 such that the saddle 27 is movable backward and forward. The transmission member 9 transmits a backward and forward movement of the saddle 27 to the auxiliary wheel 1 such that the auxiliary wheel 1 is located at the retracted position when the saddle 27 is located at a front position, and the auxiliary wheel 1 is located at the operative position when the saddle 27 is located at a rear position. The auxiliary wheel urging member 23 urges the auxiliary wheel 1 toward the retracted position. Accordingly, it is possible to achieve the auxiliary wheel mechanism that is for the two-wheeled vehicle and enables a rider to move an auxiliary wheel between a retracted position and an operative position without a manual operation of the rider.
