Also sometimes used to describe suspension components, for example a swing arm pivot axle; Bar ends: extensions at the end of straight handlebars to allow for multiple hand positions; Bar plugs or end caps: plugs for the ends of handlebars; Basket: it is an optional attachment on a bike and is used for carrying things
Unsprung mass is a consideration in the design of a vehicle's suspension and the materials chosen for its components. Beam axle suspensions, in which wheels on opposite sides are connected as a rigid unit, generally have greater unsprung mass than independent suspension systems, in which the wheels are suspended and allowed to move separately.
Traditionally, these weights have been made of lead; it is estimated that up to 500,000 pounds (230 t) of lead, having fallen off car wheels, ended up in the environment. [8] According to the US Environmental Protection Agency , worldwide these total more than 20,000 tonnes of lead annually, [ 9 ] and therefore the use of less-toxic materials ...
10-speed bicycle cassette. On a bicycle, the cassette or cluster [1] is the set of multiple sprockets that attaches to the hub on the rear wheel.A cogset works with a rear derailleur to provide multiple gear ratios to the rider.
Without being supported by the suspension's shock absorbers, in-wheel motors are themselves less shielded both from shocks and debris, reducing their durability. Some designs reduce unsprung weight by reducing the weight of the motor, for example by using a coreless design or Litz wire coil windings. These weight-saving designs may have a ...
A 1977 Harley-Davidson XLCR with seven-spoke alloy wheels manufactured by Morris [8]. High-performance motorcycles began to use cast alloy wheels (usually aluminum but sometimes magnesium) as early as the Münch Mammoth, with its single cast-elektron [9] rear wheel which was shown at the Intermot motorcycle show at Cologne in late 1966.

The only other hinge-free performance bicycle that is small enough to serve as a multi-mode commuter or that fits into an airline legal suitcase with minimal disassembly is the (unsuspended) Mezzo folding bike. A Birdy can fit into a standard airline-legal 29-inch suitcase, but this requires the pedals, wheels, and rear rack to be removed.
A Mark 2 saloon fitted with a prototype IRS demonstrated a reduction in unsprung weight of 190 lb (86 kg) compared with a live axle. [2] Its first production applications were in the E‑Type sportscar from its launch in 1961, as well as in the late 1961 introduced, line-topping Jaguar Mark X saloon. [ 3 ]
