Bicycle Gear Ratios
“How does the gear ratio on a bicycle work?”
Everyone who’s had a bicycle has probably had to deal with gear ratios. But what exactly are they and how exactly do they work? Well, put simply, the gear ratio is the ratio between one pedal turn and one wheel turn. So if you have a gear ratio of 2-1, then your bicycle’s wheel will make two complete revolutions with one full revolution of the pedal. As a result, when you are going uphill, you should shift into low gear, since you will then not have to use as much force when pedaling.
