On average, a bathroom remodeling job will cost you around twice as much as the materials cost you. For a small bathroom of roughly 100 square feet, labor costs could run an average of $12,000 or $13,000 on the high end.
The Average Bike Riding Speed. The average road bike speed is between 11 and 12 mph. Bike riding speeds vary widely depending on your riding conditions. When you are zooming down a paved hill, your speed may increase to over 20 mph, while you may slow to only a few miles per hour when you are climbing a steep or rocky grade.
If I assume that there is enough frictional force to keep the bike at this speed, then the limiting factor will be the human. This isnât a terrible assumption since motorcycles can go 100 mph (of course they have a larger mass, which does matter in this case).
