OK, here it goes...
If the speed of the object (with the sticker) increases but the circumference is doubled (frame tube), the angular velocity (degrees or radians of the angle covered by the radius connecting the object to the centre or thickness of sticker) will become double its earlier value. Its period for each rotation will become triple its earlier value and will eventually slow the foward velocity of the forgoing molecules.
On the other hand, if its angular velocity has to remain unchanged (constant), it has to move at double the velocity in the tangential direction. Its period of rotation will remain same .
I hope things are a little clearer now and I hope I have not added more confusion.
To make it really simple, the stickers are real ugly... and actually, they just make the bike look like it has 20 less horsepower :2thumbs::roll:
