Tips and safety

A bicycle multi-tool with a chain tool

Make sure both tires are properly inflated using a pressure gauge. The recommended pressure (psi) is listed on the sidewall of the tire.

Check both tires for cuts and/or embedded debris.

Try to turn the handlebar while holding the front wheel stationary to see if the stem is tight.

Squeeze both brakes and make sure they require an even amount of pull (about halfway to the grip) to contact the braking surface of the rim or rotor properly.

Spin both wheels to make sure they spin freely and do not rub the brake pads.

Make sure the quick release levers are secured properly.

Lube the chain and wipe off all excess.

Tire levers to aid in tire removal

If you must ride at night, use the best lights and reflective gear you can afford.

Ride in groups when possible.

When riding in a group, try to maneuver as a group.

Make sure your bicycle is of good quality and in good repair

.

Water and sunglasses for eye protection

Wear brightly colored clothing, lights and reflectors.

Wear sunglasses to protect your eyes from UV light, bugs, wind, and debris.

Wear tight fitted clothing so nothing gets caught in the chain.

A properly fitted quality helmet

Make sure your helmet is properly adjusted. The front of the helmet should come just above the brow ridge, the chin strap should be tight and the two straps should create a Y just beneath the ears.
