A leaning vehicle includes a body frame including a headpipe, a front wheel, a steering torque transmission including a steering shaft supported by bearings, a handlebar assembly, and a front wheel connector that transmits a steering torque, and a steering torque detector. The steering torque transmission includes a torsional deformation element upstream of a portion of the steering shaft supported by the most upstream bearing in a steering torque transmission path, and which is easily twisted and deformed by a steering torque input from grips on the handlebar assembly. The steering torque detector detects at least a portion of the steering torque input into the steering torque transmission based on a torsional deformation of the torsional deformation element.

The present invention discloses an internal steering structure of a front wheel hub of a portable two-wheeled vehicle including a front wheel mounted on a front end of a vehicle body of a two-wheeled vehicle, a handlebars provided at a front end of a vehicle body of a two-wheeled vehicle, and a steering bearing sleeve vertically fixed to the front end of the vehicle body. The steering bearing sleeve is provided with a steering bearing fixing rod which is rotatable within the steering bearing sleeve. The steering bearing fixing rod is fixedly connected to the handlebars and is rotated synchronously with the handlebars. A rotatable front wheel is provided on the steering bearing fixing rod. In the internal steering structure of the front wheel hub of the portable two-wheeled vehicle according to the present invention, the steering bearing sleeve fixed to the front end of the vehicle body and the steering bearing fixing rod rotatable in the steering bearing sleeve are provided and the internal hub and the handlebars are fixedly connected to the steering bearing fixing rod. Which achieves a balanced force, simple structure, easy operation, and which can greatly improve the driving stability.

Headsets and head tube assemblies for vehicles are provided. A vehicle includes a steerer tube and a head tube. A headset rotatably connects the steerer tube and the head tube. The headset includes a coupling ring which includes a body and a central bore defined in and extending through the body. The coupling ring is connectable to and rotatable with the steerer tube. The headset further includes a cup which includes a body and a central bore defined in and extending through the body. The cup is connectable to and rotatable with the head tube. The headset further includes a damper assembly, the damper assembly including a first damper element rotatable with the steerer tube and a second damper element rotatable with the head tube, the first damper element and the second damper element in frictional contact with and rotatable relative to each other.

A front end assembly that simplifies assembling of bicycles includes a threaded center bolt, a stem body, a stem tube, a frame head tube, and a fork steering tube with a wedge immovably fixed therein. The wedge includes a stem interface that complementarily fits with the stem tube to rotationally align the fork, and a bolt interface that engages the center bolt. The steering tube is inserted into the head tube from the bottom, and the stem tube is inserted into the head tube from the top. The center bolt threadably engages the bolt interface of the wedge to secure components together. The position of the wedge within the stem tube vertically aligns the stem body with respect to the fork steering tube. Automated alignment and tensioning eliminates much guesswork, and the assembly process is shortened.
