A collision testing vehicle is disclosed which can be utilized to perform testing with a driver assistance system. The collision testing vehicle includes a vehicle having a vehicle body. The vehicle is structured to be subject to an impact force during a collision with a collision body. A wheel is coupled to the vehicle body, and the wheel includes a detachable support that is configured to non-destructively detach from the wheel when subjected to the impact force.

An adjustable assembly for a bicycle includes a first support having an interior surface and a second support slidably positioned within at least a portion of the first support. One of the first support and the second support is adapted to attach to a first bicycle portion, and the other of the first support and the second support is adapted to attach to a second bicycle portion. Further, the second support comprises an expansion portion configured to be moved between an expanded position and a retracted position. The expansion portion is configured to engage the interior surface of the first support when the expansion portion is in an expanded position. In addition, the first support is configured to be selectively moved relative to the second support when the expansion portion is permitted to assume a retracted position.

A hidden-type shock absorbing bicycle frame has a front vehicle frame, a transmission assembly, a rear vehicle frame, and a damper. The front vehicle frame has a seat tube having two assembly plates. The assembly plate has an upper pivot hole and a lower pivot hole. An assembly space is formed between the assembly plates. The transmission assembly is pivotally connected to the upper pivot holes and has two front arms located in the assembly space and two rear arms located at two sides of the seat tube and extending backwardly. The rear vehicle frame is pivotally connected with the rear arms and is pivotally connected with the seat tube. The damper hidden inside the assembly space has a top end pivotally connected with the front arms and a bottom end pivotally connected to the lower pivot holes.

A manually-powered personal stand-on vehicle having a deck for a rider to stand on, a frame, multiple ground engaging wheels, and a drive mechanism providing power to at least one of the wheels to propel the vehicle. The deck may include a portion connected to the frame by a pivot, thereby providing a pivot axis which enables a pivoting motion of at least a portion of the deck relative to the frame. The drive mechanism is integrated with the deck such that when downward force is applied by the rider onto a portion of the deck which is upwardly angled relative to the frame in a manner which causes the portion of the deck to pivot downwards toward the frame, the drive mechanism is actuated to power at least one of the wheels for forward propulsion.

A multi-wheeled vehicle (e.g., bicycle, tricycle, quadricycle) frame includes a head tube, a seat tube, a top tube, a brace member, and a down tube. The seat tube is disposed away from the head tube. The top tube is coupled to the seat tube and coupled to the head tube. The brace member is coupled to the seat tube and coupled to the head tube. The down tube is coupled to the seat tube and coupled to the head tube.

A reinforcement device for reinforcing an electric bicycle frame at least in a region of a tube cutout of a bicycle frame tube which accommodates an energy storage. The reinforcement device includes a first reinforcement element which extends axially in the bicycle frame tube and/or extends at a certain angle to the bicycle frame tube, and at least one second reinforcement element which extends axially in the bicycle frame tube. The reinforcement device is installed in the bicycle frame tube.
