To determine which gear ratio will have the highest overall speed, we can look at the gear ratios you've provided:
- 2.26
- 2.87
- 3.5
- 4.63
In general, a higher gear ratio means that for each rotation of the pedals (or crank), the rear wheel rotates more times, resulting in a higher speed. Therefore, among the options given, the gear ratio of 4.63 will provide the highest overall speed, as it allows for more rotations of the rear wheel per rotation of the pedals compared to the other ratios.
