Welcome. On a six speed bike, there should be five noticeable up shifts, with a corresponding decrease in rpms on every shift. On 1st through 5th, there will be some resistance to upward toe pressure on the shift pedal in between shifts. Once in 6th (or whatever is the top gear on any bike), you should be able to move the shift pedal up slightly with no resistance.
When riding and you aren't sure if you are in top gear or not, just try to lift the pedal with your toe without pulling the clutch lever. If it moves, you are in top gear.
