What is a good gear ratio for a mini bike?

Asked by: Kelly Allen

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.

Are 2.5 gear ratios good?

Fixed gear bikes often run as a high of a gear as possible because coming down a hill a smaller gear ratio quickly gets out of control. Way more info than you need. A good starting point would be around 2.5:1, so a 42 would be a good place to start.

What is a good gear ratio for speed?

In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears. Lower gears are required if the car is very heavy, or if the engine makes its power at the upper end of the rpm scale.

How do you find the gear ratio on a mini bike?

It's going to turn 3600 rpm divided by ratio ratio is 10 to 1 times your wheel diameter. It's 19 times pi that's 3.14 then divided by 12 that's how many inches are in the foot.

What gear ratio is better for torque?

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.

Does higher gear mean faster bike?

Just remember that larger gears at the rear mean easier pedalling but more torque, and larger gears at the front mean harder pedalling but more speed.

How do I choose gear size?

To determine the value of module for a given gear, you measure the pitch length in millimeters and divide that value by π. For example, if the pitch length measured 9.425mm, this would be a module 3 gear. By incorporating π into the value of pitch, the metric dimensions of a spur gear are very simple to calculate.

What is the best gear ratio for BMX racing?

Classic BMX gearing evolved over the years to be 44/16, which has approximately 55 gear inches. The most popular gear ratios are pretty close to a 55 inch, which just seems to feel best for most people. The number is derived from a simple formula: (chainring size / cog size) X wheel size.

What is the best gear ratio for climbing hills?

The average gear ratio most riders enjoy going with, which is also often used in prebuilt bikes, is 48/17. Some popular alternatives are 49/16, 49/13, 48/16, 46/18, 46/17, 46/16. In other words, 46 to 49 on the chainring and 16 to 18 on the cassette will meet most people’s needs.

How can I make my 49cc pocket bike faster?

Some dirt bike companies make good Lube it should help improve speed of a pocket bike. Another. Thing you can do is take your gas tank remove the fuel lines from it and upgrade your fuel filter.

How fast will my mini bike go?

A Mini bike can go up to 25 MPH. Most minibikes are powered by a small engine, producing 2 to 5 horsepower. This is enough power for them to travel. A new rider can quickly become a seasoned, efficient driver with the right instruction and time behind the controls.

How do you pick a sprocket size?

To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.

Will a bigger sprocket faster or slower?

A bigger rear sprocket/ smaller front sprocket will give you an increase in acceleration but decrease your top speed. A smaller rear sprocket/bigger front sprocket will reduce you acceleration but increase the top speed.

How can I make my mini bike sprocket faster?

An easy way to change the power characteristics of your bike is by installing a new rear sprocket. So going up in size improves acceleration. But decreases top speed and going down in size increases.
