What are the 7 gears on a bike for? 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.
What do the 3 gears on a bike mean?
Lower numbers are the low gears, and higher numbers are the high gears. First gear is a low gear. On three-speed bikes, the gears are inside the hub of the wheel so you don't see them. Downshifting means going to a lower gear, and upshifting means going to a higher gear. You can also say shift down and shift up.
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.
Why do you use low gear when going up hills bike?
Lower gearing is easier and less fatiguing. It requires less leg strength to keep your cadence up—it is more a question of endurance than sheer strength and muscle power. The average gear ratio most riders enjoy going with, which is also often used in prebuilt bikes, is 48/17.
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.
