A bicycle includes a handlebar and a vibration generator supported on the handlebar. A sensor is configured to detect an overcoming vehicle. A controller is configured to activate the vibration generator when the sensor detects an overcoming vehicle.

A bicycle includes a frame and a seat post removably engaged with the frame. A light source is supported by the seat post. A power source is supported by the seat post. A switch is disposed between the light source and the power source.

A scooter has a front support frame that is pivotally connected to a scooter deck. A pair of front wheels are each operably mounted the front support frame via wheel pivots. At least one spring is operably mounted between the front support frame and the scooter deck for biasing the scooter deck towards a horizontal configuration, but enabling the scooter deck to move to a leaning configuration when turning. A steering transmission arm transmits lateral movement via a pair of steering rods to the front wheels, so that when the scooter deck is leaned to one of the leaning configurations, the movement causes the steering transmission arm to turn the front wheels via the steering rods.

An apparatus includes a bicycle frame defining a bore, and a bicycle seat assembly including a post received in the bore. An indicating unit is configured to indicate a first position of the post along the bore for a first user and a second position of the post along the bore for a second user. An identification unit is configured to identify the first user and the second user. A computing device includes a processor and a memory, the memory storing instruction such that the processor is programmed to instruct the indicating unit to indicate the first position when the identification unit identifies the first user and to instruct the indicating unit to indicate the second position when the identification unit identifies the second user.

Lock mounting assemblies are disclosed for storing and mounting a locking apparatus to a transportation device. The mounting assemblies include one or more straps or connectors for securing the mounting assembly to the transportation device. The mounting assemblies having a structure to securely retain the locking apparatus on the transportation device and provide easy access to and release of the locking apparatus from the mounting assembly.

A mount for a security device, the mount configured to releasably engage a security device having a predetermined cross-section, the mount comprising an elongated channel comprising a first portion and a second portion, the second portion adjacent the first portion along a length of the mount and separated from the first portion by a through-hole, through which a security device having the predetermined cross-section can be inserted at an angle relative to a longitudinal axis of the channel and rotated for alignment and engagement with the channel.
