A ride-along vehicle may include a guard that attaches to a bottom portion of a molded plastic body and covers a spring and chain assembly. The guard may also provide an attachment point for the spring through a hole in the guard. The guard may have a narrow portion that covers and helps retain the chain on a sprocket as well as a wider portion that covers the spring. An improved pumper arm and steering mechanism may include a pivot joint that is provided by rods, pins, or bolts attached to opposite sides of the pumper arm. The universal joint between the steering arm and the pumper arm can be aligned with the center of the pivot point to prevent rocking of the steering arm as the pumper arm is actuated.

The apparatus comprises a rotary to variable linear converter which functions to steer a pivotable rotatable directional wheel of a vehicle.

The converter comprises a driven rotatable cylinder and a rotatable pivotable friction wheel pressed against the surface of the cylinder so that they rotate together. The friction wheel is slidably mounted on guide rods extending parallel to the cylinder surface so that the friction wheel can advance helically along the cylinder if angled relative to the cylinder axis. The friction wheel generates a lateral force which is used to apply torque to the directional wheel to turn it. The orientation of the friction wheel is varied and controlled by a digit-operated control lever operated by a rider of the vehicle.

A scooter (5) includes a head tube (50); a riser tube (51) freely and rotatably pivoted with the head tube (50), the upper end of the riser tube being provided with a handle (511); a preceding runner (52) provided at the lower end of the riser tube (51); a left carrier (53) and a right carrier (53) both connected to the head tube (50); a left back runner (54) and a right back runner (54) provided at the left carrier (53) and the right carrier (53) respectively, which support the scooter (5) alone with the preceding runner (52); the front end of each carrier (53) is provided with a cantilever (533) respectively. The left cantilever (533) and the right cantilever (533) are both provided at the head tube (50) in a suspending form of swinging back and forth freely. Provided between the left cantilever, the right cantilever (533) and the head tube (50) is a holding means (55) enabling the left carrier and the right carrier to perform back and forth alternate swing and displacement action. The scooter (5) is provided with the holding means (55) between the left cantilever, the right cantilever, and the head tube (50). When two feet of the user exert force on the corresponding carrier alternately or two hands exert force on the handle alternately to drive the head tube (50) to swing left and right, by means of the effect of the holding means (55), the left cantilever (533) and the right cantilever (533) will swing back and forth alternately on the head tube (50) and then drives the left carrier (53) and the right carrier (53) to perform alternate back and forth displacement action together, so that the traveling and handling of the scooter (5) is smoother, faster and more labor-saving.

The present invention relates to a bicycle propelling device capable of transferring power to a bicycle wheel by using the gripping force of both hands. The present propelling device uses the gripping force, and thus overcomes the problem of prior art hand and foot bicycles in which balance is easily lost during driving because the prior art hand and foot bicycles require the use of the arms. The propelling device can be used together with a pedaling operation when greater power is required while the user is riding the bicycle as usual, thereby improving the running efficiency of the bicycle. Furthermore, the propelling device is formed by combining simple devices including a string and a freewheel, and thus a bicycle can maintain the original structure thereof as it is, so that it does not cause any disadvantage or difference when the user rides the bicycle by stepping on pedals in a conventional manner.
