A bicycle handlebar stem or stem/handlebar assembly has an inclined linear travel approximately 45 degrees from horizontal. This inclined path mimics a rider's natural arm inclination and pitching moment. 45 degrees is nearly ideal for most dropped bar road bicycles but different style bicycles may have an ideal angle between 30 and 60 degrees.

Respectively a rider of the autonomous scooter may select a manual drive mode to drive without any assistance, or the rider may control the autonomous scooter remotely by a smartphone when riding or not aboard via a smartphone APP whereby the rider may engage a user interface system providing virtual driving control settings linked with an autonomous drive system to control the autonomous scooter, or the rider can manually control the autonomous scooter. Primarily elements of the autonomous scooter may comprise a platform defined by a front end and a rear end, a deck section to place the rider's feet thereon, and having a base supporting a steering column. Accordingly the steering column is rotatably connected by a motorized wheel adapter configured to turn a suspension fork arrangement containing at least one motorized wheel thus steering and balance control of the autonomous scooter, or the steering column is connected to a truck arrangement containing two motorized wheels, whereby the two motorized wheels provide balance and differential propulsion for steering the autonomous scooter. The motorized wheel adapter and the motorized wheels are systematically controlled by an autonomous drive system adapted to control the autonomous scooter during autonomous drive mode setting.

A bicycle includes a frame, a suspension assembly and a steering assembly. The frame includes a head tube that rotatably receives a front fork assembly. A steerer tube extends axially away from a fork crown of the front fork assembly. The suspension assembly includes an upper tubular support longitudinally slidable relative to a lower tubular support. The upper and lower supports receive a first positive biasing means and a first negative biasing means. The lower and upper supports are respectively connected to the steerer tube and a stem of the steering assembly such that the upper support slides longitudinally relative to the lower support adjacent the stem and above the fork crown.

A transmission element for arrangement between a handlebar stem and an upper headset includes a cover ring which, in the mounted state, covers an upper headset. An intermediate ring surrounding a head tube is arranged above the cover ring. To compensate for clearance changes of the headsets, a pretensioning element is arranged between the cover ring and the intermediate ring.

A motorcycle handlebar riser having upper and lower members. The upper member has a proximal end and a distal end. A first vertical plane laterally bisects the upper member. The upper member distal end has a bar bed to hold a handlebar. The upper member proximal end has a generally flat first attachment face oriented at a predetermined angle relative to the first vertical plane. The lower member has a proximal end and a distal end that releasably attaches to the motorcycle front fork. A second vertical plane laterally bisects the lower member. The lower member proximal end has a generally flat second attachment face oriented at a predetermined angle relative to the second vertical plane. The riser assembles in a first configuration when the attachment faces are axially aligned in one orientation and assembles in a second configuration when the attachment faces are axially aligned in a different orientation.

A bicycle handlebar includes a handlebar body and a recessed structure. The handlebar body has an outer surface. The recessed structure is recessed from the outer surface of the handlebar body, and has a mounting surface that is indented from the outer surface of the handlebar body and that is adapted for a control device to be mounted thereto.
