Ask your dealer to point out the features of your specific bicycle. A. Bike fit 1. Is your bike the right size? To check, see Section 3.A. If your bicycle is too large or too small for you, you may lose control and fall. If your new bike is not the right size, ask your dealer to exchange it before you ride it. 2. Is the saddle at the right height? To check, see Section 3.B. If you adjust your saddle height, make sure that you follow the Minimum Insertion instructions in Section 3.B. 3. Are saddle and seatpost securely clamped? A correctly tightened saddle will allow no saddle movement in any direction. See Section 3.B for details. 4. Are the stem and handlebars at the right height for you? If not, see Section 3.C on what you can do about it. 6. Can you comfortably operate the brakes? If not, you may be able to adjust their angle and reach. See Section 3.D and 3.E for details. 7. Do you fully understand how to operate your new bicycle? If not, before you ride, have your dealer explain any functions or features which you do not understand. B. Safety first 1. Always wear an approved helmet when riding your bike, and follow the helmet manufacturer’s instructions for fit, use and care of your helmet. 2. Do you have all the other required and recommended safety equipment? See Section 2. It’s your responsibility to familiarize yourself with the laws of the areas where you ride, and to comply with all applicable laws. 3. If your bike has wheel quick releases, do you know how to correctly operate them? Check Section Appendix B to make sure. Riding with an improperly adjusted wheel quick release can cause the wheel to wobble or disengage from the bicycle, and cause serious injury or death. 4. If your bike has clipless (“step-in”) pedals, make sure you know how they work (see Section 4.C.3). These pedals require special techniques and skills. Follow the pedal manufacturer’s instructions for use, adjustment and care. 5. Does your bike have suspension? If so, check Section 4.F. Suspension can change the way a bicycle performs. Follow the suspension manufacturer’s instructions for use, adjustment and care. 6. Do you have “toe overlap”? On smaller framed bicycles your toe may be able to contact the front wheel when a pedal is all the way forward and the wheel is turned. See section 4.C.1. C. Mechanical Safety Check Routinely check the condition of your bicycle before every ride. Nuts, bolts & straps: Make sure nothing is loose. Lift the front wheel off the ground by two or three inches, then let it bounce on the ground. Anything sound, feel or look loose? Do a quick visual and tactile inspection of the whole bike. Any loose parts or accessories? If so, secure them. If you’re not sure, ask someone with experience to check. 4 Tires & Wheels: Make sure tires are correctly inflated (see Section 4.G.1). Check by putting one hand on the saddle, one on the intersection of the handlebars and stem, then bouncing your weight on the bike while looking at tire deflection. Compare what you see with how it looks when you know the tires are correctly inflated; and adjust if necessary. Tires in good shape? Spin each wheel slowly and look for cuts in the tread and sidewall. Replace damaged tires before riding the bike. Wheels true? Spin each wheel and check for brake clearance and side-to-side wobble. If a wheel wobbles side to side even slightly, or rubs against or hits the brake pads, take the bike to a qualified bike shop to have the wheel trued. ! CAUTION: Wheels must be true for the brakes to work effectively. Wheel truing is a skill which requires special tools and experience. Do not attempt to true a wheel unless you have the knowledge, experience and tools needed to do the job correctly. Brakes: Check the brakes for proper operation (see Section 4.A). Squeeze the brake levers. Are the brake quick-releases closed? All control cables seated and securely engaged? Do the brake pads contact the wheel rim squarely and make full contact with the rim? Do the brake pads touch the wheel rim within an inch of brake lever movement? Can you apply full braking force at the levers without having them touch the handlebar? If not, your brakes need adjustment. Do not ride the bike until the brakes are properly adjusted. Quick Releases: If your bike has front wheel, rear wheel or seat post quick releases, make sure they are properly adjusted and in the locked position. See Section Appendix B. Handlebar and saddle alignment: Make sure the saddle and handlebar stem are parallel to the bike’s center line and clamped tight enough so that you can’t twist them out of alignment. See Section 3.B and 3.C. If not, align and tighten them. Handlebar ends: Make sure the handlebar grips are secure and in good condition. If not, replace them. Make sure the handlebar ends are plugged. If not, plug them before you ride. ! WARNING: Loose or damaged handlebar grips can cause you to lose control and fall. Unplugged handlebars can cut your body, and can cause serious in...
