Based on the tried and tested height adjustment of the Speedlifter Classic with a quick-release lever. By lifting a release lever that firmly engages in the driving position, the two-part, CNC-manufactured component made of high-strength, black anodized aluminum can be rotated horizontally in a matter of seconds. The release lever automatically engages in the parking position when the handlebar unit is rotated. This greatly reduces the overall width of the bicycle. The bicycle can now, for example, be parked or transported to save space. Retrofitting the Speedlifter-Twist system is possible on bicycles with 1 1/8'' A-Head metal fork shafts.
