My 2012 Montague FIT folding bike has started to “snake” especially when riding at speed downhill. I have tightened the frame quick release and inspected and tightened the pivot nut but the snaking still persists.
The wheels are ok and there is no play on the bottom bracket yet if I put weight on the pedals I can get the frame to shift/“snake” sideways.
When cycling up hill there is no issue but there is slight snaking on the flat which gets worse when gathering speed downhill.
Any explanation and resolution would be much appreciated since in the U.K. there is a dearth of Montague outlets and repair shops willing to service/repair their folding bikes.
