Today’s invention is bicycle handlebars which can be reconfigured into many different styles.
The front forks are made of tubes in circular arcs. Other tubes are fitted telescopically inside these.
The interior ones can be pulled out almost completely, twisted through an angle and locked in place.
This allows, for example, a more upright riding position (A) or a much more aggressive racing pose (B) -as well as almost any other arrangement in between.
These tubes could also be slid inside one another and locked in place so that a parked bicycle would be impossible to ride away and hard to sell on.
