A bicycle propulsion system including a concentric rotor assembly and a chassis assembly. The concentric rotor assembly: defines an outer drive surface; defines an inner retention surface; includes a set of sprocket brackets arranged about the inner retention surface of the concentric rotor assembly and configured to engage with teeth of a bicycle sprocket; and is configured to engage around the bicycle sprocket, wherein a center axis of the outer drive surface is concentric with a rotational axis of the bicycle sprocket. The chassis assembly: is configured to secure to a stay of the bicycle; includes a retention subassembly configured to translationally constrain the concentric rotor assembly relative to the chassis assembly; includes a drive subassembly configured to engage the outer drive surface of the concentric rotor assembly; and includes a motor configured to rotate the concentric rotor assembly via the drive subassembly.

A running bike includes a front fork, a rear fork, a handlebar, and a frame extending between and connecting the front fork and the rear fork. The frame has a top tube and a seat tube coupled to the top tube. A seat is adjustably coupled to the seat tube. A footrest is connected to and supported by the frame, a drivetrain receiving region is defined as an area below the top tube and above the footplate, a drivetrain assembly is positioned within the drivetrain receiving region, and a battery mount selectively receives a battery. The battery mount faces the front wheel at a position between the top tube and the footrest. A side panel is coupled to the frame to enclose the drivetrain assembly within the drivetrain receiving region, and has in side view, a plurality of edges positioned between the top tube and the footrest.

A bicycle includes a frame, a motor, a battery, a key interface, a crank set, and a shell. The frame defines a cavity and an opening providing access to the cavity. The motor is coupled to frame beneath the cavity. The battery extends at least partially into the frame. The battery is configured to power the motor. The key interface is positioned along an exterior of the frame. Turning a key in the key interface releases the battery to facilitate removing the battery from the frame. The crank set is coupled to the motor. The crank set includes crank arms. The shell extends at least partially over the opening.

A bicycle includes a frame, a cover, a door, a first key interface, and a second key interface. The frame defines a cavity, a first opening providing access to the cavity, an interior compartment, and a second opening providing access to the interior compartment. The cover extends across the first opening. The door extends across the second opening. The first key interface is positioned along the frame proximate the first opening. Turning a key in the first key interface releases at least a portion of the cover from the frame. The second key interface is positioned along the frame proximate the second opening. Turning a key in the second key interface releases at least a portion of the door from the frame.

A power transmission unit for electric bicycles includes an input structure, an output structure, a torque detection unit, a detection target, and a detection unit. The input structure includes an input shaft. The input shaft is caused to rotate by external force transmitted thereto. The input structure rotates along with the input shaft. The output structure outputs rotational power by rotating along with the input structure. The torque detection unit is provided on an outer periphery of the input structure. The detection target rotates either along with, or while interlocking with, the input structure. The detection unit detects a rotational state of the detection target. At least part of the torque detection unit and at least part of the detection target overlap with each other when viewed perpendicularly to a rotational axis of the input structure.
