Wheel flop refers to steering behavior in which a bicycle or motorcycle tends to turn more than expected due to the front wheel "flopping" over when the handlebars are rotated. Wheel flop is caused by the lowering of the front end of a bicycle or motorcycle as the handlebars are rotated away from the "straight ahead" position.
A chain drive and rear derailleur gear change, the most popular system in use today A shaft-drive with crankset and rear gear hub. Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels.
Chain tensioner: a device to maintain proper chain tension; Chaintug: a device to aid in setting the proper chain tension; Cluster: a bicycle cogset, either a freewheel, or cassette; Cogset: the set of rear sprockets that attaches to the hub on the rear wheel; Cone: holds bearings in place, pressed against the cup; Cotter: pin for attaching ...
The engine braking forces in conventional clutches will normally be transmitted back along the drive chain causing the rear wheel to hop, chatter or lose traction. [3] This is especially noted on larger displacement four-stroke engines , which have greater engine braking than their two-stroke or smaller displacement counterparts.
The chain in use on modern bicycles has a 1 ⁄ 2 inch (12.7 mm) pitch, which is the distance from one pin center to another, ANSI standard #40, where the 4 in "#40" indicates the pitch of the chain in eighths of an inch; and ISO standard 606 (metric) #8, where the 8 indicates the pitch in sixteenths of an inch.
A Rohloff Speedhub hub gear A Shimano XT rear derailleur on a mountain bike A bicycle gearbox with chain tensioner. Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, and the rate at which the drive wheel turns.
At a marathon the planners have a course maximum of 26 miles; a motorcycle ride would cover that while just getting warmed up. For most rides, a group ride organizer isn’t going to be applying ...
When braking, depending on the location of the combined center of mass of the bike and rider with respect to the point where the front wheel contacts the ground, and if the front brake is applied hard enough, bikes can either: skid the front wheel which may or not result in a crash; or flip the bike and rider over the front wheel.
