Chain is Missing or Lost
If a chain is missing or lost use the Chain Length
Calculator to determine what size chain is needed. Enter the number
of Motor Sprocket Teeth and Wheel/Axle Sprocket Teeth along with the Center
to Center Distance between the two sprockets and click the Calculate button. The
number of chain links that are needed will be displayed in the Chain Links box.
Installing Different Size Sprockets
Use the calculators above to determine what size chain is needed when
installing a different size sprocket or sprockets onto your electric scooter, bike, go kart,
or other similar type of vehicle.
To determine what size chain is needed:
1- Use the Sprocket Center to Center Calculator to determine the
center to center distance between the existing sprockets. The sprockets center
to center distance will remain the same when different size sprockets are
installed.
The sprockets center to center distance can also be measured with a
tape measure however this may not be as accurate as using the calculator if the motor shaft and axle ends are offset from each other.
2- Enter the center to center distance between the two sprockets into the
Chain Length Calculator. You can use the "Copy to Calculator Above" checkbox to do this if you wish.
3- Enter the new motor sprocket teeth number and or wheel/axle sprocket
teeth number into the Chain Length Calculator and click the Calculate button.
The number of chain links that are needed for the modification will be
displayed in the Chain Links box.
4- Chains can be cut in even numbers only so round up the Chain
Links number to the nearest even number. For example if the Chain Links result
is 127.42 then round it up to 128 and purchase a 128 link chain.
