A method for providing guided navigation for personal transport devices is described. In one embodiment, the method includes providing a list of predetermined destinations associated with a geographic area, projecting directions to one or more of the destinations on a ground surface located in front of a personal transport device, and providing an option to a user of the personal transport device to select between at least two different destinations. A direction associated with each destination of the at least two destinations may be projected on the ground surface located in front of the personal transport device. The method also includes receiving an input from the user indicating a selection of one of the at least two different destinations and projecting directions to the selected destination on the ground surface located in front of the personal transport device to guide the user to the selected destination.

A method for controlling engine braking in a vehicle comprises: determining a position of a throttle operator; determining a speed of the vehicle; and determining an engine braking mode selected. In response to the position of the throttle operator being a fully released position and the selected braking mode being a first engine braking mode: controlling an engine and a position of a throttle valve according to the first engine braking mode for applying a first level of engine braking. In response to the position of the throttle operator being the fully released position and the selected braking mode being the second engine braking mode: controlling the engine and the position of the throttle valve according to the second engine braking mode based at least on the speed of the vehicle for applying a second level of engine braking. A vehicle implementing the method is also disclosed.

A method for accelerating a vehicle from rest. The method includes receiving a mode indication indicating a launch control mode selected; receiving a brake-on indication; controlling the engine according to a launch control strategy; determining an accelerator position; for an accelerator position greater than zero, controlling the engine to: increase open a throttle valve and control the engine to limit engine torque output; receiving a brake-off indication; controlling the engine according to the standard control strategy, controlling the engine according to the standard control strategy with the braking system having been released causing the vehicle to accelerate from rest, a first rate of acceleration from rest of the vehicle being greater than a second rate of acceleration from rest of the vehicle for corresponding changes in accelerator position, the first rate corresponding to accelerating from rest after controlling the engine according to the standard and launch control strategies.

A bicycle operating apparatus for wirelessly controlling at least one component of a bicycle includes a carrier element on a fastening device for fixing the bicycle operating apparatus to a handlebar of the bicycle, a housing attachable to the carrier element having an energy storage compartment for receiving an energy storage element and having an electronic circuit arrangement in the housing. At least one switch is connected to the electronic circuit arrangement on the housing. An operating component mounted on the carrier element to be pivotable about an operating axis preloaded into a neutral position which is able to be deflected out of the neutral position in a first direction of rotation about the operating axis in order to actuate the switch, and the operating axis extends obliquely with respect to the flat outer surface.
