Tires / Wheels
• The front and rear wheels are laced 20” x 4” wheels.
• The tires are 20” x 4.0” low rolling resistance hybrid tires suitable for mixed ter
rain use with inner tubes and a rim liner.
• The tube size for both the front and rear tires is 20” x 4”.
• The tires are designed for durability and safety for regular cycling activities but
must be checked before each ride for proper ination and condition.
• Tires must be inated using a pump with a Schrader valve tip.
NOTE: Recommended tire pressure is 20 PSI MAX. Always check the condi-
tion of the tires and rims for damage, cracks, or deformation.
The torque of the front wheel axle nuts is 14.50 ft lbs (19.65 Nm).
1. It is essential that the proper air pressure be maintained in the tires all the time.
Do not under-inate or over-inate your tires. Low pressure can cause reduced
range and loss of control and tires that are over inated can burst.
2. Failure to maintain the proper air pressure rating indicated in the handbook
may at any time result in the tire and/or wheel failure.
Inate your tires from a regulated air source with an available tire gauge. Inat
ing your
tires with an unregulated air source could over-inate them, resulting in an
exploded tire.
3. When tire wear becomes obvious or a hole in the tire is found, you must re
place the tires and/or tubes before using the bike, otherwise injury to operators
and/or damage to your bike could occur.
4. Proper ination, good maintenance, and quick replacement will help ensure
that the operational characteristics of your bike will be maintained and danger-
ous conditions avoided. In addition to proper ination, correct wheel alignment
helps to decrease tire wear. If you nd a tire that is worn unevenly, have a
professional cycle mechanic check the wheel alignment.
Chain Care
The Brat comes equipped with a chain tensioner. We recommended that you inspect the
chain tensioner for wear and periodically clean and lube the chain and tensioner.
