How do you calculate gear ratio on bike?
- Gear ratio’s in the bike gear ratio chart are determined by dividing the number of teeth on the front chainring by the number of teeth on the rear cog. A larger number indicates a large gear that is harder to turn over and is used for higher speed.

What gears for what speed on bike?
While the rider should change the gears more in instincts and the ideal speed varies depending on the situation, the approximate speed range are like this: 0 to 15 km/h for first gear, 15 to 30 km/h for second gear, 30 to 40 km/h for third, 40 to 55 km/h for fourth, and 55 km/h and higher for fifth and sixth gears.
When should I use certain gears on a bike?
It’s about efficiency and having a much broader range, or choice, of gears for a given situation. Just like a car, bicycles benefit from a low gear to accelerate from a standstill, or to climb a steep hill, and at the other end of the scale a high gear helps you to achieve high speeds without over-revving.
Is gear 1 high or low on a bike?
Bikes generally have 1, 3, 18, 21, 24, or 27 speeds. (10- and 15-speeds are obsolete and you don’t see them on new bikes anymore.) Lower numbers are the low gears, and higher numbers are the high gears. First gear is a low gear.
What gear should I use on a flat road?
Middle gear is perfect for regular terrain on flat roads. When you need some strength but not too much to ride on undulating terrain, you can shift your gear to the middle level. For that, you have to combine middle chainring on triple rear cogs to ride on flat roads smoothly.
How do you use gears on a bike for beginners?
Get to grips with shifting your bike gears with these super quick beginner tips.
- Practice Makes Perfect.
- Right = Rear, Left = Front.
- Don’t cross the chain!
- Anticipate the hill.
- Left = big changes, Right = fine tuning.
- Don’t shift too quickly.
What is the easiest gear on a bike?
The low gear is the “easy” gear and is primarily used when climbing. The low gear is the smallest chain ring in the front, and the largest cog on the rear cassette. In this position pedaling will be easiest and the least amount of force will be required to push the pedals.
Do you pedal while shifting gears?
You must be pedaling when you change gears. That’s because the chain has to be moving in order for the derailleurs to “derail” the chain from sprocket to sprocket. If you click the shifters without pedaling, the gears won’t change until you do start pedaling, and when you do, you’ll hear some very disconcerting noises.
What gear do you use to go uphill?
While going uphill, use the D1, D2, or D3 gears to maintain higher RPMs and give your vehicle more climbing power and speed. Note: Most automatic vehicles have at least a D1 and D2 gear, while some models also have a D3 gear.
Is a lower gear harder to pedal?
The larger the cog the ‘lower’ the gear and the easier it will be to pedal, but the slower you will go.
What is the best gear ratio for a road bike?
Most new endurance and entry level road bikes are specced with 50/34 chainsets, racing bikes with 52/36, and time trial bikes with 53/39. This is good news for most riders as the gearing corresponds to the type of riding for which the bike is intended.
How many gears do I need on my bike?
For a daily commute, you may want to make sure you have at least 3 gears. Unless you’re on entirely flat terrain the entire way, you’ll want the option to shift up and down. You’re going to work, after all, you don’t want to show up sweatier than necessary.
What is gear 7 on a bike?
On a 7-speed bike, the lower gears make it easier to pedal and the higher gears allow for better movement going downhill. Compared to a 3-speed bike, a 7-speed is preferable for a rider who travels on varying terrain.
