摘要：
A vehicle comprising: steering means for operation by a user； one or more rear groundengaging wheels； a first front ground-engaging wheel located substantially in the centre at substantially the front of the vehicle and being steerable in response to operation of the steering means； second and third front ground-engaging wheels located either side of the first front ground-engaging wheel； and adjustment means for adjusting the steer angle and the height of the second and third front ground-engaging wheels depending on the steer angle of the first front ground-engaging wheel, the adjustment means being configured such that: when the first front ground-engaging wheel has a straight-ahead steer angle, the steer angles of the second and third front ground-engaging wheels are also straight-ahead and all three front ground-engaging wheels are in contact with the ground； and when the steer angle of the first front ground-engaging wheel is turned such that motion of the vehicle would describe a curve, the steer angle of the front ground-engaging wheel on the outside of said curve is turned at least partly towards the steer angle of the first front ground-engaging wheel, the steer angle of the front ground-engaging wheel on the inside of said curve is not substantially turned towards the steer angle of the first front ground-engaging wheel, and the height of the front ground-engaging wheel on the inside of said curve is raised relative to the height of the front ground-engaging wheel on the outside of said curve, the first front groundengaging wheel and the front ground-engaging wheel on the outside of said curve remaining in contact with the ground.一載具包括：供使用者操作之操控構件；一或多個後方地面接合車輪；一第一前方地面接合車輪，該第一前方地面接合車輪實質位於該載具之前方中央並可回應於該操控構件之操作而操控；位於該第一前方地面接合車輪之兩側的第二及第三前方地面接合車輪；以及調整構件，該調整構件視該第一前方地面接合車輪之操控角度來調整該第二及第三前方地面接合車輪之操控角度及高度，該調整構件係經組配為：當該第一前方地面接合車輪具有一直線前進操控角度時，該第二及第三前方地面接合車輪之操控角度亦為直線前進且所有該前方地面接合車輪皆與地面接觸；且當該第一前方地面接合車輪之操控角度被轉動使該載具之動作界定一弧度時
