The battery assembly is slidable into the down tube from the lower end of the down tube along the down tube axis. The battery assembly includes a battery housing protruding from the lower end of the down tube, and a battery cover secured to a lower end of the battery housing and substantially enclosing the lower end of the battery housing. At least a portion of the battery housing may extend below a horizontal plane defined by the crank axis.

Abstract: A bicycle comprises a wheel, a frame supported on the wheel and including a tube hole, a motor mounted to the frame, a battery including battery hole extending completely through the battery, and a battery mounting pin extending through the battery hole and tube hole to secure the battery to the frame. In one embodiment, the tube includes spaced-apart first and second walls, with the tube hole through the first wall and a threaded hole through the second wall and aligned with the tube hole. Preferably, the battery mounting pin includes a threaded end, and the battery mounting pin is positioned through the tube hole and through the battery hole with the threaded end threaded into the threaded hole. The invention is also embodied in a method of mounting a battery to an ebike including the steps of aligning the battery hole with the tube hole and inserting a battery mounting pin through the tube hole and completely through the battery hole.

Abstract: An electronic device can be mounted at least partly in a frame of a bicycle and used to monitor operations or properties of the bicycle or one or more components associated with the bicycle. The electronic device may integrate and communicate with a variety of components including sensors to facilitate customization of monitoring by the electronic device. The electronic device can have a relatively minimalist design. The electronic device, in some embodiments, may include a display that does not present alphanumeric characters to an operator, and the display may instead include multiple indicators that individually or in combination present information to the operator, such as the level of charge of one or more batteries or an operating mode of the electronic device or bicycle.

Abstract: 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.

Abstract: The present invention provides a bicycle comprising a wheel, a frame including a wheel support supported by the wheel, a motor mounted to the frame, and a speed sensor mounted to the wheel support. Preferably, the wheel is a rear wheel and the wheel support is a rear wheel support. The speed sensor is positioned to sense rotation of the rear wheel. In one embodiment, the frame can also include a chainstay and a seatstay, and the rear wheel support couples the chainstay to the seatstay. Preferably, the rear wheel support includes an inner face, and the speed sensor is secured to the inner face. For example, the rear wheel support can be a left rear wheel support and the entirety of the speed sensor is not visible from a left side of the bicycle.

Abstract: The present invention provides an ebike comprising a wheel, a frame supported on the wheel, a motor for driving the wheel, and a battery for powering the motor. The battery includes a control panel that facilitates control of operation of the battery. For example, the control panel can include a power button to turn the battery on or off, plus and minus buttons to select different modes of the battery, and/or a series of lights that indicate a battery charge. Preferably, the series of lights form a closed loop around the power button and/or plus and minus buttons.

Abstract: The present invention provides a bicycle comprising a motor mounted to a motor mount of the bicycle frame. The motor mount includes a down tube mount coupled to a down tube, a chainstay mount coupled to a chainstay, and a side brace secured to the down tube mount and wrapping around one side of the motor to the chainstay mount. Preferably, when viewed from the side, the side brace extends directly from the down tube mount to the chainstay mount. Preferably, the motor mount further comprises a lower support secured to the down tube mount and wrapped around a bottom of the motor to the chainstay mount. The motor mount can further include an upper support connecting the seat tube mount to the down tube mount. This upper support can include an upper flange secured to the motor.
