Your 18-speed bicycle uses two derailleurs to change between different gear ratios , which allow you to shift into lower gears for climbing and higher gears when you’re moving faster. ... The rings are different sizes, but the spring in the derailleur arm keeps the chain taut no matter which gears you choose.
What is the difference between a 21 speed and 18-speed bicycle?
The most obvious difference between both bikes is the different number of gears and different gear setups. ... 21-speed bikes have 7 sprockets with 3 chainrings at the front, while 18-speed bikes have 6 rear sprockets with the same number of chainrings.
How do you use gears on a bike for beginners?
- Practice Makes Perfect. ...
- Right = Rear, Left = Front. ...

- Don’t shift too quickly.
How do gears on a bike work?
Bicycles have gears to make going uphill easier, and also to facilitate going faster on level ground. ... The bicycle gear system works by sliding the shifter on the handlebars . A bicycle gear system involves Downshifting and Upshifting – Downshifting means going to a lower gear and Upshifting means going to a higher gear.
What gear should I use on a flat road?
For riding on flat roads, it is recommended to use the middle gear . It is a common choice among bikers as it helps you reduce pressure from your feet onto the pedals.
How many gears does a 18 speed bike have?
18 speeds is a common drivetrain configuration for modern bicycles, with options for a double chainring paired with a 9-gear cassette or a triple chainring with a 6-gear cassette.
What gear should you be in going uphill on a bike?
Low Gear = Easy = Good for Climbing: The “low” gear on your bike is the smallest chain ring in the front and the largest cog on your cassette (rear gears). In this position, the pedaling will be the easiest and you’ll be able to pedal uphill with the smallest amount of resistance.
How many gears do I need on a bike?
Three gears work nicely – a pulling off gear, a low gear for hills, and a high gear for the flat.
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.
What gear ratio is best for climbing?
A common setup on a road bike adapted for climbing is a compact road crankset with 50-34 chainrings and an 11-32 cassette, which gives a lowest gear of 34:32 or a ratio of 1.06:1 .
What gears should I use on my bike?
So put simply: if you want a short fast ride that will make you fatigued quickly but increase your ‘power’, use higher gears . If you’re out all day, be conservative and twiddle lower gears.
Do you shift gears while pedaling?
Rule 1. You must be pedaling when you change gears . ... 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. You also don’t want to shift the gears while standing still.
How do you explain bike gears to a child?
Explain again which way the gears go. Low gear, low number = faster legs, lower effort, up hills . High gear, higher number = harder on the legs, more effort, downhill. N’s gears also have an up and down symbol so you can explain that as well if your child’s bike has that.
