Anyways, from the last time I spoke about my riding experiences, I have improved my riding stance. Some points one may need to consider if he rides a cruiser bike:
* Never lock the elbows (this can be achieved by relaxing the shoulders and keeping them low) - after all, ideally the bike is kept in balance with your body weight and not with your arms
* Use a centred riding stance - this will most probably put your knees automatically in a correct position
* Lean with the bike - if you turn left, shift the body to the left, and vice-versa
* Tuck your knees firmly against the fuel tank
* The arms should be parallel to the ground
* Lean your back a little bit to the front as if you're gonna take a sports bike stance - in reality what you are doing is straightening the back - you get the sensation of leaning forward because of the bike's layback seat :)
I will try to take a photo of my riding stance. I'm quite sure this will help a lot of beginners.
