Handlebar not straight
When the handlebar or the stem pole is not aligned with the wheel and fork, the steering of the bicycle feels off, sometimes described as mis-aligned, not straight, unbalanced.
- Adjust stem position
- Locate two horizontal pinch bolts on the stem base
- Untighten the two bolts with 6mm Hex key
- Straighten the handlebar, so that the folding mechanism is at 45 degree angle
- Tighten the two pinch bolts on the stem
- Repeat if needed
