4 Getting Started: Buying a Bike How much to spend? What am I going to use my bike for? How fit am I? Where will I ride? What kind of terrain will I be riding? How hilly is it? Will I need carrying capacity? Will I ride with a group? Do I want to ride off-road? Toy store, warehouse store, discount store?

5 The basic qualities of a good bike that will serve you well for many miles: Wheels – Aluminum rims, stainless steel spokes Frame – Strong, but light: steel, aluminum, titanium or carbon fiber Bearings – Sealed for long life and ease of maintenance Brakes – Powerful and easy to use Shifters – indexed and at your fingertips

6 Getting Started: Opportunity Cost Strength Weight Cost

7 Getting Started: Bike Types: Mountain

8 Getting Started: Bike Types: Road

9 Getting Started: Bike Types: Hybrid

10 = Getting Started: Bike Types: Commuter

11 Getting Started: Bike Types: Recumbent

12 Getting Started: Bike Types: Designed for women

13 Getting Started: Bike Fit

14 Getting Started: Saddle Height With the ball of the foot on the pedal, there should be a slight bend in the knee when the pedal is at the very bottom of the pedal stroke. If your hips rock when pedaling, the seat is too high.

15 Getting Started: Saddle Angle The saddle should be flat.

16 With horizontal pedals, front of knee should be directly over middle of pedal. Getting Started: Saddle fore/aft

17 Getting Started: Saddle Type A saddle should support your pelvic bones and be narrow enough to prevent chafing.

18 Getting Started: Handlebars

19 Getting Started: Brake Lever Position

20 Handlebar Stem Length and rise should be determined by riding style. Generally, longer and lower for more aggressive riders, shorter and higher for more relaxed riding.

21 Getting Started: Pedals

22 Getting Started: Cranks

23 Getting Started: Helmet Try on several in the store Position – Level Fit – Snug, Bend over test Straps – Y under the ear, Tight Do not use crashed helmets

24 Getting Started: Other Equipment Gloves Cycling Shoes Cycling Shorts, tights Cycling Jersey Rain Gear Cold Weather Gear Glasses Locks Lights Hydration System – Bottles, Camelback

25 Getting Started: ABC Quick Check A is for Air B is for Brakes C is for Cranks, Chain, Cassette (Drive train) Quick is for quick releases Check is for a brief, slow ride to test shifting, brakes and everything else is working properly

26 Getting Started: Road Tools Minimal – Tube and/or repair kit – Tire levers – Pump and/or power inflator – 4, 5 & 6mm Hex Wrench Useful – Multi tool – Chain tool – Extra spoke – Tape Safety – ID – First Aid – Change – Dollar Bill – Phone

27 Getting Started: Tire Repair PrestaSchrader

28 Teeth Cogs LOW GEAR ( move chain to extreme left ) HIGH GEAR (move chain to extreme right) Rear (cassette) Front (chainrings) Getting Started: Gearing

29 CHAIN Front CHAINRINGS (Teeth: 52 48 24) Rear CASSETTE 5 Cogs Teeth: 14 17 21 26 32 Getting Started: Gearing

30 Most Riding: Getting Started: Gearing

31 Uphill: Easy Pedal Low Gear Left Position Getting Started: Gearing

32 Downhill: Hard Pedal High Gear Right Position Getting Started: Gearing

33 DON”T: OR Getting Started: Gearing

34 General Rules Most often keep chain on MIDDLE chainring Shift only when pedalling Don’t push hard on pedals when shifting Shift rear derailleur: – Going uphill (or against wind) -------Left – Going downhill (speed increases) -- Right – Big uphill coming up: Shift front chainring – Left Shift before being on hill Getting Started: Gearing

35 LOW GEAR (move chain to extreme left) Rear (cartridge) Front 22 teeth 30 teeth Getting Started: Gearing

36 Bicycle Gear Ratios LOW GEAR A typical bicycle has wheels that are 26 inches in diameter. The "lowest" gear ratio on the bike might be a front chain wheel with 22 teeth and a rear gear having 30 teeth. A gear ratio of 0.73-to-1 (22/30) means that for each pedal revolution, the rear wheel turns 0.73 times Getting Started: Gearing

37 Bicycle Gear Ratios LOW GEAR For each pedal revolution, the bike moves about 60 in (3.1416 x 26 x.73 = 59.6 in) This is 0.00096 miles/rev At 60 RPM: 60 rev/min x 60 min/hr x 0.00096 miles/rev = 3. 4 mph (At a 60 RPM pedaling rate, the speed of the bike is 3.4 mph ) Getting Started: Gearing

38 HIGH GEAR (move chain to extreme right) Rear (cartridge) Front 44 teeth 11 teeth Getting Started: Gearing

39 The "highest" gear ratio on the bike might be a front chain wheel with 44 teeth and a rear gear having 11 teeth. A gear ratio of 4.0-to-1 (44/11) means that for each pedal revolution, the rear wheel turns 4 times For each pedal revolution, the bike moves forward about 326 inches (3.1416 x 26 in x 4= 326 in) Bicycle Gear Ratios HIGH GEAR Getting Started: Gearing

40 For each pedal revolution, the bike moves about 326 inches (3.1416 x 26 in x 4= 326 in) This is 0.0051 miles/rev At 60 RPM: 60 rev/min x 60 min/hr x 0.0051 miles/rev = 18.4 mph (At a 60 RPM pedaling rate, the speed of the bike is 18.4 mph ) Bicycle Gear Ratios HIGH GEAR Getting Started: Gearing

41 Getting Started: Brake System Inspection Check to make sure the rim and the brake pads are clean. Wipe rim clean and sand the brake pad with sandpaper. Check cables for freedom of movement. Enlist the assistance of a bicycle mechanic if you find difficulties with the cables. Inspect the levers - they must be firmly installed and there must be at least 2 cm (3/4 inch) clearance between the lever and handlebars when the brake is fully applied. If necessary, tighten, lubricate, and adjust. Make sure the brake arms move freely without resistance, and that they return to clear the wheel fully when the lever is released. If necessary, adjust, lubricate or replace.

42 Getting Started: Brake Pad Adjustment Centered on rim Toe in Ensure not touching tire Check operation, fine tune as necessary Can clean pad with sand paper

43 Getting Started: Chain Lube Oils are messy and collect dirt Paraffin or teflon lubes are cleaner Apply periodically with light coat Wipe off excess Avoid solvents NEVER USE WD-40

44 Getting Started: Helmet Try on several in the store Position – Level Fit – Snug, Bend over test Straps – Y under the ear, Tight Do not use crashed helmets

45 Getting Started: Other Equipment Gloves Cycling Shoes Cycling Shorts, tights Cycling Jersey Rain Gear Cold Weather Gear Glasses Locks Lights Hydration System – Bottles, Camelback

46 Getting Started: ABC Quick Check A is for Air B is for Brakes C is for Cranks, Chain, Cassette (Drive train) Quick is for quick releases Check is for a brief, slow ride to test shifting, brakes and everything else is working properly

47 Getting Started: Steering a Straight Line Bike wants to go in a straight line Caster Effect The Lean Effect

48 Getting Started: Starting Power Position Dominant foot on pedal with crank in 2 o’clock position (for right and 10 o’clock for left) Push off, push down pedal, bring ground foot Power position gives burst of speed giving more stability sooner

49 Getting Started: Stopping Recommended you put your right foot down first to lean away from traffic While braking, put left pedal down Downshift Shift weight to left pedal Slide off saddle Put right foot down and turn handlebars to slightly to left Dismount to right avoid traffic

50 Getting Started: Scanning Head Scan Body Scan Avoid wobbling Communication Make eye contact Show your face

51 Getting Started: Signaling

52 On the Road: Principles of Traffic Law First Come, First Serve Drive on the right-hand side of roadway Avoid door zone Yield to crossing traffic Yield when changing lanes Speed Positioning Intersection Positioning

53 Cyclists fare best when they act and are treated as drivers of vehicles.

54 On the Road: Bicycling in Traffic: Lane Position Rule Ride just to the right of the motorized traffic when the lane is wide enough to safely share. When lanes are too narrow to safely share, ride in the center of the lane or just to the right of the center in the right hand tire track. If traveling at the speed of traffic, a bicyclist should use the entire lane (take the lane). If traveling faster than other traffic, overtake on the left, keeping a safe distance from slower traffic.

55 On the Road: Bicycling in Traffic: Turn Lane Rule Ride in the rightmost lane that goes to your destination. In single destination lanes, ride on the right-hand side of the lane. In multiple- destination lanes, ride in the side of the lane appropriate for your destination and current traffic conditions.

56 On the Road: Bicycling in Traffic: Changing Lanes Plan ahead Look behind, perhaps several times Signal intention Act carefully, smoothly and deliberately Negotiate as necessary Never move in front of another vehicle so closely as to constitute a hazard

57 On the Road: Bicycling in Traffic: Lane Positioning Basic Maneuvers: Straight Through Right Turn Left Turn Overtaking Passing Parked Cars

58 On the Road: Bicycling in Traffic: Lane Positioning ONE-WAY STREET Right turn from right side of lane. Left turn from left side of lane if there is little turning traffic, from center or right side of lane if left and straight traffic is heavy.

59 On the Road: Bicycling in Traffic: Lane Positioning RIGHT-TURN ONLY LANE

60 On the Road: Bicycling in Traffic: Lane Positioning DUAL DESTINATION RIGHT-LANE TURN

61 On the Road: Bicycling in Traffic: Lane Positioning TWO-WAY STREETS Left turn from left side of lane. Right turn from right side of lane.

62 On the Road: Bicycling in Traffic: Lane Positioning TWO LANE ROAD WITH NO TURN LANE

63 On the Road: Bicycling in Traffic: Lane Positioning ROAD WITH LEFT- TURN-ONLY LANE

64 On the Road: Bicycling in Traffic: Lane Positioning ROAD WITH CONTINUOUS LEFT TURN LANE

65 On the Road: Bicycling in Traffic: Lane Positioning ROAD WITH CONTINUOUS LEFT TURN LANE

66 On the Road: Bicycling in Traffic: Lane Positioning MULTILANE ROAD WITH NO TURN LANE

67 On the Road: Emergency Maneuvers: Rock Dodge

68 On the Road: Emergency Maneuvers: Quick Stop quick stop

69 On the Road: Emergency Maneuvers: Instant Turn

70 Coping: Crash Prevention 1.Control You Bike – Don’t fall or collide with others 2.Obey the Rules – Don’t cause traffic crashes 3.Choose the Correct Position in the Lane – discourage other drivers’ mistakes 4.Learn Hazard Avoidance Skills – avoid other drivers mistakes 5.Wear a helmet – survive a crash

71 Coping: Crash Avoidance: Avoidance & Collision 50% of bicycle accidents are falls caused by road hazard, cyclist mistake, etc. FaultReasonPercentage BicyclistsRiding wrong way facing traffic14 MotoristLeft turn in front of cyclist13 MotoristRight turn in of cyclist11 BicyclistLeft turn from right side of road11 BicyclistsFailure to yield from driveway9 BicyclistRunning stop sign or signal8 MotoristRunning stop sign or signal8 MotoristOpen car door in front of cyclist7 MotoristFailure to yield from driveway6 All Others8

72 Coping: More stats Most car/bike collisions involving child cyclists are caused by the child. Most car/bike collisions involving adult cyclists are caused by the motorist. The more cyclists there are, the lower the per capita casualty rates

73 Coping: Motorist Errors at Intersections Motorist Left Turn Without Yielding to Straight-through Cyclist Prevention: – Be visible wear bright-colored clothing, establish eye contact, use lights at night – Be predictable maintain proper lane position, ride a straight line – Be assertive plan to take your appropriate right-of-way, and act accordingly – Be alert assess the situation and be prepared to take evasive action Avoidance: – Quick Stop – Instant Turn

74 Coping: Motorist Errors at Intersections Motorist Right Turn, Cutting in Front of Straight-through Cyclist Prevention: – Be visible wear bright-colored clothing, establish eye contact, don’t ride in motorist’s blind spot; – Be predictable maintain proper lane position, ride a straight line, do not pass motorist on right; – Be assertive take your appropriate right-of-way, and act accordingly – Be alert assess the situation, look for a turn signal or watch the front wheel of the car, be prepared to take evasive action. Avoidance: – Quick Stop – Instant Turn

75 Coping: Motorist Errors at Intersections Motorist Pulling out into Traffic from Cross Street Without Yielding to Straight-Through Cyclist Prevention: – Be visible establish eye contact or use sound to make the motorist aware of you; – Be predictable maintain position well away from the road's edge so you are visible and positioned where motorists expect to see traffic, and so you are not blocked from view by any parked cars, ride a straight line; – Be assertive plan to take your appropriate right-of-way, and act accordingly; – Be alert assess the situation, and be prepared to take evasive action. Avoidance: – Quick Stop – Instant Turn

76 Coping: Road Hazards Dogs Kids Wind Blasts Railroad Tracks and Surface Defects Storm Grates Steel Plates and Uneven Road Surfaces

77 Coping: Crash/Injury Prevention Wear helmet - %85 of bicycle fatalities are brain injuries Keep brakes in good working order Wear highly visible clothing Anticipate road and traffic hazards Practice your skills!

78 Coping: Riding Enjoyment Shift smoothly – match conditions, anticipate change in conditions How to shift – take pressure off pedals while shifting Cadence – revolutions per minute (75 -95) Pace – 10 to 20 mph for several hours while touring

79 Coping: Nutrition Basics Eat before you are hungry and drink before you are thirsty Carbs – Simple – Sugars from fruits and vegetables – provide instant energy – Complex – starches – provide sustained energy – Carb rich meal night before a big ride and bagel, etc. morning of Fats – avoid Proteins – Dried fruits, nuts, commercial products

80 Coping: Hydration Drink before you are thirsty Plan to drink 1 20oz bottle per hour or 12 to 14 miles. More be required on hot day Dehydration can make you feel sick and/or lightheaded Should stop riding and rehydrate if feeling symptoms Sports drinks can help with water replacement and nutrients

81 Coping: Trail Etiquette Be Courteous (yeild to other users) Give audible and hand signals when passing Yield when entering or crossing other trails Keep right Pass on the left Be predictable Use lights at night Do not block trail Do not litter

82 Coping: Group Riding Use Signals Give Warnings – Change in direction or speed Announce overtaking – “On your left/right” Announce Hazards to group Watch for traffic overtaking from the rear Watch out at intersections Leave gap for cars – when riding slow, like going uphill, leave space for cars every three or four riders Move off the road when stopped Single file/two abreast Grouping at intersections

83 Coping: Educating Motorists Did you know? 98 million people in the United States own bicycles? About 750 bicyclists are killed each year in the U.S.? 96% of bicyclists’ deaths result from crashes with motor vehicles? In all 50 states, bicyclists have the same rights and responsibilities as drivers of motor vehicles?

84 Coping: EducatingMotorists Learn How To Safely Share The Road With Bicyclists Leave at least three feet of passing space between the right side of your vehicle and a bicyclist. Be aware that when a road is too narrow for cars and bikes to ride safely side by side, bicyclists should take the travel lane, which means riding in or near the center of the lane. Reduce your speed when passing a cyclist, especially if the roadway is narrow. When turning left at an intersection, yield to an oncoming bicyclist just as you would yield to oncoming motorists. After passing a cyclist on your right, check over your shoulder to make sure you have allowed adequate distance before merging back in. Don’t blast your horn when approaching bicyclists. In inclement weather, give cyclists extra trailing and passing room, just as you would other motorists. Learn to recognize situations and obstacles that may be hazardous to cyclists, such as potholes, debris, and glass, and then give them adequate space to maneuver. Look for bicyclists before opening your car door. Children on bicycles often act unpredictably. Expect the unexpected.

85 What To Watch For Unfortunately, not everyone who rides a bike understands or obeys the rules of the road. Some of the common cyclist errors you may encounter as a motorist are: Wrong-way riding. Cyclists riding on the left (wrong) side of the road, facing traffic cause 14% of all car/bike crashes. Look both ways before turning. Mid-block ride-outs. This is the most frequent crash type for young riders and occurs when the bicyclist enters the roadway from a driveway, alley, or curb without slowing, stopping, or looking for traffic. Cyclist’s failure to yield to crossing traffic (25% of car/bike collisions). Cyclist’s failure to yield when changing lanes (13% of car/bike collisions). Coping: Education Motorists
