A bicycle includes a transmission having two switchable drives between a driver body on which rear sprockets are positioned and a wheel hub of a rear wheel. The bicycle has actuation elements for switching between drives and operating elements for operating the actuation elements. The bicycle includes only a single front sprocket. The actuation elements are embodied in an electrical version and the operating elements are electrically coupled to the actuation elements. By advantageously selecting the drives of the driver between the cassette housing and wheel hub, a front derailleur may be omitted. The driver allows operation with only little energy, since the chain need not be shifted. consequently, the actuation elements require little energy for changing the drive between the crank axle and the wheel hub of the bicycle, so that it is pre-eminently suitable for these actuation elements and their operation to be executed as an electrical version.

Generally, examples described herein may take the form of a bicycle including a front frame, a rear frame operably associated with the front frame and configured for coupling to a rear wheel, and a suspension system operably associated with the front frame and the rear frame. The suspension system includes a first connection structure operably coupling the front frame to the rear frame and a first sliding body pivotally coupled to the rear frame and configured to travel in a first direction along a substantially linear travel path and in a second direction opposite the first direction along the substantially linear travel path as the suspension system is compressed.

A bicycle having a rear wheel including an axle, a hub shell, a torque element including a torque output portion and a torque input portion, and a rear cog coupled to the torque input portion. The torque output portion is a first radial distance from the torque input portion. The position sensor measures a rotational position of the torque input portion relative to the torque output portion. In one embodiment, the position sensor includes a displacement indicator (e.g., a radial tab mounted to the torque output portion) and a displacement sensor (e.g., an inductive sensor mounted to the torque input portion). The inductive sensor preferably has two sensing coils positioned on each side of the displacement indicator. The hub assembly can further comprise a wireless transmitter adapted to transmit data from the position sensor. The hub shell preferably includes a window that facilitates data transmission from the wireless transmitter.

Bicycle dropouts to secure a rear axle of a bicycle include a dropout with locking channels formed over a portion of its face, and a corresponding locking plate with complementary channels formed over one face. The locking plate surrounds the rear axle and the locking and complementary channels engage to prevent the rear axle from moving in the dropout. When the locking plate is loosened so that the channels can disengage, the rear axle position can be adjusted forward and backward to loosen or tighten the chain.

A system for biomechanical analysis of user posture and automatic customized manufacture of bicycle parts includes a servo-assisted simulator having a handlebar, a saddle, pedal cranks, and actuators, a device detecting input data that includes a 3D scanner for automatically detecting the position of body segments of the user and the angular ranges therebetween and generating three-dimensional physical data units, an electronic platform detecting pressure data of the user, a pair of insoles detecting plantar pressure, a computer connected to the actuators and to the detection device, a memory unit storing optimized initial data and instantaneous data, software comparing the optimized initial data and the instantaneous data and generating final data of the characteristics of the main parts, a spatial representation device spatially representing the final data, and a device for immediate manufacture of the parts using 3D printers. A method of biomechanical analysis and custom manufacture of bicycle parts.

An ebike comprises a front wheel, a rear wheel, a frame structure supported on the front wheel and the rear wheel, a crank assembly, and a battery assembly. The frame structure can include a front fork supported on the front wheel, a head tube coupled to the front fork, and a down tube extending downward and rearward from the head tube, the down tube defining a down tube axis and being open at its lower end. The crank assembly can be supported by the frame structure and can be rotatable about a crank axis that is spaced rearward from the down tube axis. The battery assembly can be at least partially secured in the down tube in an installed position and can be slidable into the down tube from the lower end of the down tube along the down tube axis.
