How it Works

Calculation & Analysis

Calculated Power Required in three steps:

1. Power to move uphill

2. Power to overcome wind resistance

3. Power to overcome rolling resistance


Assumptions Made

1. Rear wheel diameter = 1.2 meters

2. The uphill splope gradient = 20 degrees

3. Bicycle velocity while uphill travel = 15 km/hr

4. Maximum velocity of bicycle = 25 km/hr

5. Weight of bicycle & rider = 120kgs
