The present disclosure is directed to lean angle indication for motorcycles. The disclosure provides a motorcycle lean angle indication device that is operationally configured to be attached to a motorcycle and contact a surface that a motorcycle is traveling upon when the motorcycle realizes a target lean angle when executing a turning maneuver.

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 includes a down tube defining a down tube axis and being open at its lower end. The crank assembly is rotatable about a crank axis that is spaced rearward from the down tube axis. 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.

A vehicle wind buffeting shield, a vehicle incorporating a wind buffeting shield, and a method of diverting upward air flow during operation of a vehicle using a wind buffeting shield are provided. The wind buffeting shield includes a flow restricting portion and at least one mounting member. The at least one mounting member couples the flow restricting portion proximate a bottom portion of a gas tank of a vehicle such that the flow restricting portion projects generally horizontal and outwards from the vehicle and restricts upward air flow during operation of the vehicle.

A bicycle pedal crank arm hole protection device. The device comprises an insert installed into the crank arm hole when pedals have been removed. A mechanism to aid in the installation and removal of the device along with further protection of the device itself when removed for storage.

A bicycle drive system includes a front face gear, a rear face gear, a drive shaft, and a front roller-toothed gear assembly coupled to the first end of the drive shaft, and a rear roller-toothed gear assembly coupled to the second end of the drive shaft. Both the front roller-toothed gear assembly and the rear roller-toothed gear assembly include one or more roller elements. The roller-toothed gear assemblies are advantageous in ensuring the bicycle drive system is highly efficient, and is only minimally or not at all affected by dirt, water, contaminants, or other foreign matter typically experienced in un-clean riding conditions.

A straddled vehicle includes a front wheel, a front fork, a cover, a brake, a brake hose, and a protector. The front fork rotatably supports the front wheel. The cover is disposed in front of the front fork. The brake is attached to the front wheel. The brake hose is connected to the brake and extends upward behind the cover. The protector is attached to the brake hose. The brake hose includes a first hose, a second hose, and a shrink tube. The second hose is provided separately from the first hose. The shrink tube is disposed behind the cover and connects the first hose and the second hose. The protector is disposed behind the cover and covers the shrink tube.
