I just tried my bike for a test run in the park today. I can hear weird noises when changing gear sometimes. Which I dont hear from my Dahon.
It happened like twice during my 15mins ride.

I feel a bit cheated when I desperately try to make the bike stand vertically on its own and it can't. Even though the trailer video shows the bike stand vertically perfectly. Right now, it will roll and drop to the floor if i try to leave it standing on its own.
