What is a good gear ratio for a mini bike?

Ratios do vary with wheel size, weight & other conditions, however you should keep your gear ratio at approx 6 to 1. Any ratio either smaller or larger will put too much torque through the clutch and cause it to slip, which will cause the clutch to overheat and the clutch will no longer function.

What is a good gear ratio bike?

For flat places, a ratio of 2.6 to 3.0 is ideal for most people. The lower value of this range, with a cadence of 90 rpm, will allow us to ride around 30km/h, while the upper, 34km/h. If you’re just starting out on your adventure on a single speed or fixed gear bike, a gear ratio of around 2.7-2.8 will be ideal.

What is the best gearbox ratio?

1 to 1 or direct gear, is always the best gear for fuel mileage, quietness, cooler temperatures in the transmission, and more pulling power. However, to run in direct gear, the rear gears must be either 2.64, 2.47, 2.21 and I think there is even a higher gear than the 2.21. The average speed today is 70 miles per hour.

What is the best first gear ratio?

For most street performance applications, a 10:1 final First gear ratio is usually considered optimal. The disadvantage of operating a 4.10:1 axle ratio on the street with a 1:1 high gear is excessive freeway engine speed.

What is a 3 1 gear ratio?

3. 1. This is another way of saying that gear A rotates 3 times while gear B rotates 1 time. It’s the same as saying the gear ratio is 3:1. If we know the number of times gear A rotates we can divide that number by 3 to find the number of times gear B rotates.

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.

Is 46 16 A good gear ratio?

A 46/16 gear ratio (2.88) on the other hand, provides higher top speeds, and is more efficient than the 44/16 – however acceleration will be more difficult. The 46/16 will permit you to travel farther with each pedal (you’ll basically have longer legs) and therefore cover more distance with less effort.

What are 3.55 gears good for?

With a 3.55 being a higher numerical number, Garrison says it will put more torque to the tire, allowing for faster acceleration and better performance on hill climbs.

How do I choose the right gearbox?

How to Select a Gearbox

  1. Speed and horsepower of the input.
  2. Desired output speed or desired output torque (will determine ratio)
  3. Characteristics of use; hours per day, nature of shock or vibration in the system.
  4. Degree of overhung load.
  5. Unit configuration, shaft input or hollow bore input, shaft output or hollow bore output.

What are 3.73 gears good for?

A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21.

What rear end gears should I use?

The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy. This is a good ratio for the occasional towing or hauling individual. For a person who tows more often, and heavier loads, the 3:73 or 4:10 may be more appropriate.

How do I know my rear gear ratio?

Turn the wheel TWO revolutions and count the number of driveshaft turns. The number of driveshaft rotations will help you determine your rear axle ratio. For example, if it turned 3 and a half times, it’s a 3.50:1 ratio. If it turned 4 and a quarter times, it’s a 4.25:1 ratio.

Does higher gear ratio mean faster?

Higher ratios mean the engine has to run faster to achieve a given speed. Lower ratios allow the engine to run more economically to maintain that given speed.

How can I make my gear ratio faster?

To go FASTER – You want a lower numbered gear ratio. Your wheels will make more rotations for every engine rotation. You will sacrifice low end “punch” (acceleration) and you won’t jump off the line as fast. To Jump off the line quicker (wheelie) – Raise the gear ratio.

What does a small gear ratio mean?

The smaller gear has to spin twice to cover the same distance covered when the larger gear spins once. Most gears that you see in real life have teeth. The teeth have three advantages: They prevent slippage between the gears. Therefore, axles connected by gears are always synchronized exactly with one another.
