A bottle holder for an external battery which comprises a longitudinal base designed to be fitted to a tube of the frame of an electric bicycle. Where the bottle holder comprises a main body attached to the base and the main body and the base partially form a cavity intended to house an external battery or a water bottle.The main body is also capable of adapting the size of the cavity in such a way as to accommodate the external battery with a non-circular section and larger than the water bottle section, and furthermore, the main body comprises an adjustment mechanism for closing the cavity holder and preventing the external battery from moving around inside the holder. In this way, the invention allows the user to be able to house an external battery or a water bottle using one single holder without changing different holders.

An electric wheel hub is provided, including: a shell; a motor assembly, including a stator, a rotor and a shaft, the stator and the rotor being received in the shell and relatively rotatable, the rotor being connected and rotatable with the shell, the shaft defining an axial direction and a circumferential direction, the shaft being movable in the axial direction and disposed through the stator, the shaft and the stator being relatively non-rotatable in the circumferential direction; and a battery unit, received in the shell, electrically connected with the motor assembly.

An electric bicycle control device, and associated display device, are described. The control device, in some embodiments, includes an LED (light emitting diode) indicator (e.g., alphanumeric display) that presents information to riders of the electric bicycle, as well as various control buttons that facilitate rider control of the electric bicycle. The control device is associated with a display device, which presents additional or complementary information about the electric bicycle, such as information that is presented based on input received via the control device from the rider.

An electric bicycle has an outer double frame, on which a steering plug with a handlebar and a front wheel with a sleeve is mounted in front of a hinge, and a rear wheel with the sleeve is attached behind. A seat is secured to the outer double frame. An internal double frame is built into the outer double frame, each double frame being a spatial construction of profile tubes rigidly connected by interconnected fastening elements with cutouts into which a battery unit is mounted. The fastening elements are triangular in shape, with at least three of these elements being located in front of the outer double frame, and one element attached to the rear side of the outer double frame. Inside the structure is strengthened by vertical elements in the angle form, with the possibility of horizontal movement. The seat is fixed to the outer double frame on a triangular element. Rear motor-wheel connected to the battery unit secured by the shock absorber element to the outer double frame on one side and a movable pendulum pivotally secured to the outer double frame on the other. The rear motor-wheel is also attached to the controller.

Various technologies for reducing or increasing a speed of a vehicle by rotating its handlebar.

Disclosed is a method for controlling power supplied to an electric drive system of an electric bicycle. The method includes determining a pedal assist power level for the electric drive system, determining a first current to be applied to the electric drive system based on the pedal assist power level, detecting a user selected boost assist at a first input while the first current is being applied to the electric drive system, and determining a second current to be applied to the electric drive system based at least in part on both the user selected boost assist and a boost trigger, the boost trigger being received via a second input.

A bicycle comprises front and rear wheels, a frame supported on the front and rear wheels and including a frame mount, and a battery including a battery mount engaged with the frame mount. One of the battery mount and the frame mount includes a depression and the other of the battery mount and the frame mount includes a boss positioned in the depression. Preferably, depression comprises a slot, and the slot can include a resilient material to securely hold the boss. The boss can comprise an eccentric boss. Preferably, the battery mount is positioned adjacent one end of the battery, and an opposite end of the battery includes an opening. In this embodiment, the bicycle further comprises a mounting pin positioned through the opening and through a portion of the frame to secure the opposite end of the battery to the frame.
