A vehicle includes a dual linkage assembly coupled to two front wheels and a fork. The dual linkage assembly includes arms coupled at pivot points. Each arm rotates independently at the pivot points and responds to force applied by the rider, such that both front wheels maintain contact with the ground. The vehicle further includes a lock assembly including a lever and a lock block coupled to the front fork, a first piece with a first notch coupled to one or more of the arms, and a second piece with a second notch coupled to a head tube. When locked, the lock block engages the first notch, preventing the dual linkage assembly from rotating, and engages the second notch, preventing the fork from rotating. The vehicle is then capable of standing upright without assistance from a rider or stand.
