  • the movement of the pedals 21, 31 is imposed on the handle ⁇ bars 22, 32 via the pedal bar 23, the pedal hinge 25, con ⁇ nection bar 24 and the adjustment hinges 100, 200 when locked.
  • the handlebars 22, 32 therefore move dependently of the pedals 21, 31. Vice versa, the same applies; any forces applied on the handlebars 22, 32 contribute to the movement of the pedals 21, 31.

  • the crank set 4 and the transmission chain 40 convert these reciprocating movements into a rotary driving movement of the first wheel 11, thereby propelling the vehicle 1 in the first direction A or the second direction B.
  • the operator of the vehicle 1 can shift his balance to the left or to the right, relative to the on-going first direction A or second direction B, thereby tilting the vehicle 1 around the tilt ⁇ ing axis E and as a result thereof pivoting the hanger 72, shown in figures 4 and 8, relative to the base plate 70 within the freedom of movement imposed by the pivot socket 71. Because of the offset angle of thirty-eight to fifty degrees with respect to the horizontal plane of the base plate 70, the hanger 72 will not only tilt around the hori ⁇ zontal tilting axis E relative to the base plate 70, but also turn around the vertical steering axis F, enabling the operator to steer the vehicle 1 by tilting the vehicle 1.

  • any rotation of the grip sections 27, 37 results in a movement of the grip knobs 26, 36 at the end of the grip sections 27, 37 trough a non- vertical, tilted plane. Therefore, as the grip sections 27, 37 are rotated around respectively the adjustment P and Q, the grip knobs 26, 36 move away or towards each other, to respectively a widespread position and a narrow position in relation to each other.
  • Figure 7A shows an exemplary angular position of the handlebars 22, 32 in a widespread position, wherein the grip sections 27, 37 tangentially prolong the curvature of the connection bars 24, 34.
  • the grip knobs 26, 36 at the ends of the handle ⁇ bars 22, 32 are positioned to the sides of the vehicle 1, extending in the sideways direction of the vehicle 1 past the pedals 21, 31.
  • the grip knobs 26, 36 reciprocate along the side of the body of the operator.
  • the operator could also operate the vehicle 1 when facing in the rearwards direction B, as the grip knobs 26, 36 at the ends of the respective grip sections 27, 37 move alongside his body.
  • Figure 7B shows an exemplary angular position of the handlebars 22, 32 in a narrow position, wherein the grip sections 27, 37 have been moved in the forward direction A in relation to the situation shown in figure 7A.
  • Figure 3 shows, with dotted lines indicated with VIIB, that the grip knobs 26, 36 are positioned closer together, for example as far as the pedals 21, 31 extend in the sideways direction of the vehicle 1. The operator should slightly lean in the forward direction A to grip the grip knobs 26, 36 at the ends of the respective grip sections 27, 37. Therefore, when the vehicle 1 is operated, the grip knobs 26, 36 reciprocate in front of the operator.
  • Figure 7C shows an exemplary angular position of the handlebars 22, 32 in a narrow, compact position which prepares the vehicle 1 to become compact for storage pur- poses.
  • the grip sections 27, 37 are rotated downwards rela ⁇ tive to the situation shown in figure 7A and extend down ⁇ wardly from the adjustment hinges 100, 200 towards the bottom of the vehicle 1.
  • Figure 3 shows, with dotted lines indicated with VIIC, that the grip knobs 26, 37 at the ends of the respective grip sections 27, 37 are positioned closer together at the bottom of the vehicle 1, in particular next to the pedal hinges 25, 35 instead of the widespread posi ⁇ tion during use as shown in figure 7A. In this way, the height of the vehicle 1, which is normally determined by the height of the grip sections 27, 37, is now reduced to the highest point of the backbone 5.
  • the fork section 6 and the first wheel 11 attached thereto can be folded in folding direction U underneath the convex side the backbone 5, shown in figure 7D. This is achieved by sliding the locking sleeve 69 in direction K, as shown in detail in figure 7E, thereby unlocking the fold hinge 68 between the first support bar 66 and the second support bar 67.
  • vehicle 1 could be categorized as being of the tricycle type, an alternative embodiment could feature two, four or more wheels.
