A two-wheeler vehicle comprising a steerable front wheel of at least 16" (df), a fixed back wheel smaller than or equal (db) to df. A distance between the back wheel ground contact point and the front wheel contact point is smaller than or equal to (12" + V(df db). A steering mechanism defines a steering axis ground contact point. A trail distance between the steering axis ground contact point and the front wheel ground contact point is between 5% and 10% of the df. The steering mechanism comprises a fork, a yoke and a handlebar. A frame interconnects the yoke and the center of the back wheel and comprises a standing mechanism providing at least one footboard, below the back wheel center, extending laterally from the frame. |
