A wheel hub motor, hub motor, or in-wheel motor is a motor that is incorporated into the hub of the wheel. Wheel-hub motors are commonly found on electric bicycles. Electric hub motors were well received in early electric cars, but have not been commercially successful in modern production cars [1] [2] because they negatively affect vehicle ...
A hub gear, [1] internal-gear hub, [2] internally geared hub [3] or just gear hub [4] is a gear ratio changing system commonly used on bicycles that is implemented with planetary or epicyclic gears. The gears and lubricants are sealed within the shell of the hub gear, in contrast with derailleur gears where the gears and mechanism are exposed ...
They can be used individually, as an external derailleur or an internal hub gear, or in combinations such as the SRAM Dual Drive, which uses a standard 8 or 9-speed cassette mounted on a three-speed internally geared hub, offering a similar gear range as a bicycle with a cassette and triple chainrings. Derailleur gears. Cogset; Crankset; Hub gear
The only application currently commercialized is the internally geared bicycle hub. The NuVinci CVT replaces derailleurs and other internally geared hubs, and provides a gear ratio range of about 350%, similar to that on bicycles with 8- or 9-speed hub gears, or with double chain rings (most racing or fast road bicycles).

The Sachs 301/A (Germany) was a popular 30cc 2-stroke developed in the late 70's that was later copied by Pro-Rotary (Taiwan) in the late 90's as an RH-01 and sold in markets such as Australia. The design is that of a hub motor with considerable internal gear reduction resulting in low-output RPM hence low measured power.
Shimano Alfine SG-S700 11 speed epicyclic internally geared hub, without auxiliary components. Alfine is a comfort and urban oriented product series by Shimano.It is mainly known for internally geared hubs, but includes also hydraulic disc brakes and levers, chain tensioners, dynamo hubs, cranksets, shift levers, and complete wheels.
All Sturmey-Archer gear hubs use epicyclic (planetary) geartrains of varying complexity. The AW is the simplest, using one set of planetary gears with four planets. The AM uses three compound planets with differently sized cogs machined from a common shaft to engage the gear ring and sun gear separately, while the close-ratio three-speeds, and hubs with four or more speeds, use multiple ...
The Speedhub is more expensive than competing bicycle gear systems (both hub gears and derailleur gears), and it is some 100 grams heavier than a comparable set of derailleur gears, [2] but offers about the same gear range (and at its ratio of 5.26:1 more range than a typical road bike ratio of 4.28:1 with 50/34 chainrings and 11 to 32 tooth ...
