variable angle bike in aluminium ultralight

this bike is made from aluminium using a brand new design to allow the axial movement of the headstock. The construction of the frame is from 2 side plates which thereby allows the angular motion of the headstock:

The headstock has a 10 degree movement operated from a click shift (twist grip) on the left hand bar. The important thing to note is the adjustment can be mad on the fly and the bike stays level whatever the angle set:


headstock with 10 degree adjustment of fork angle (60-70 degree )height compensated adjustment


clamp levers securely clamp the headstock once adjusted
