The invention further relates to a vehicle control unit, in particular a bicycle control unit, programmed to control at least one optical feedback unit for use in a vehicle, preferably a bicycle, in particular an electric bicycle according to the invention. The invention moreover relates to an assembly of at least one optical feedback unit according to the invention and at least one vehicle control unit, in particular a bicycle control unit, according to the invention.
Over the last 150 years, the bicycle has evolved to become one of the most efficient means of transportation in terms of conversion of energy into distance travelled. The efficiency of the bicycle has also been optimized to minimize the effort required by the rider. For instance, most modern bicycles include an efficient gear system to minimize rider effort. To further reduce the amount of human effort required to propel a bicycle, a variety of electric bicycles (e-bikes) have been introduced, wherein use is made of an electromotor as auxiliary power source to assist the manpowered pedaling process. These developments have resulted in faster bicycles, which facilitates bicycling at high speeds. Because of the increased speed, bicycle riding has become increasingly more dangerous, which leads to increased risks for cyclists to become involved in accidents with other vehicles and pedestrians. Furthermore, due to ongoing technical developments more and more data are collected, which can be used for various purposes. There is a need to increase data feedback from the e-bike to the user, in particular during cycling, which among others allows the user to drive the e-bike in a safer and more controlled manner.
Itis a first object of the invention to provide an improved bicycle, in particular an electric bicycle, which allows to the user to receive bicycle status related feedback during cycling.
It is a second object of the invention to provide an improved bicycle, in particular an electric bicycle, with an improved optical solution to provide bicycle status related feedback to the user during cycling.
Atleast one of these objects can be met by providing a bicycle, in particular an electric bicycle, and/or a bicycle part, comprising: + preferably a bicycle frame, e a handlebar rotatably mounted or mountable to said bicycle frame, e at least one optical feedback unit for providing bicycle and/or user related optical feedback, in particular bicycle drive status related feedback, to a user of the bicycle, wherein said optical feedback unit is mounted to and/or at least partially accommodated within said handlebar, wherein said optical feedback unit comprises: - an array and/or group of optical elements, preferably light emitting diodes (LEDs), - preferably at least one casing which is at least partially transparent and/or translucent, and which at least partially covers said optical elements, wherein said casing preferably has an exposed outer surface which is substantially similarly shaped to at least one adjacent outer surface portion of the handlebar, and - wherein at least one of the plurality of optical elements is controllable based on a control signal to provide said optical feedback to the user, and e preferably at least one bicycle control unit for generating at least one control signal for controlling at least one optical element of said optical feedback unit.

In this way feedback, preferably bicycle and/or user related feedback, can be provided to the user in a simple and efficient manner. The optical feedback given to the user can be of (very) basic nature, for example by,
dependent on the feedback to be provided to the user, illuminating (switching on) more optical elements or less optical elements, and/or by changing the illumination level and/or colour temperature of one or more optical elements. In a basic embodiment of the optical feedback unit, the unit comprises two, three, four, of five optical elements, such as LEDs, which are arranged in a row, which array of optical elements may e.g. function as linear gauge or linear chart.

Preferably, an exposed outer surface of said casing or alternative cover layer is preferably substantially similarly shaped to at least one adjacent outer surface portion of the handlebar. This leads to a compact construction of the optical feedback unit(s) on and/or within the handlebar, which prevents, or at least reduces the risk of, damaging of the optical feedback unit(s), and which moreover, leads to a more aerodynamic design of the bicycle, which saves energy during cycling.

Figure 2 shows a part of the handlebar 1 as shown in figure 1, wherein the grip 3 and brake system 4 are removed for explanatory purposes. The feedback unit 2 according to the invention may be arranged in the area A. In particular the feedback unit 2 may abut the handlebar body 9, which is located in a transition portion 8 of the handlebar 1. That is, in the transition portion 8 of the handlebar 1, a diameter of the handlebar 1 decreases from a first diameter D1 to a second diameter D2. In particular the handlebar 1 comprises opposing narrowed end portions integrally connected to the central handlebar portion 12, wherein each of said narrowed end portions is at least partially accommodated within a grip 3 of the handlebar. The second diameter is preferably smaller than the first diameter. As such, an exterior surface of the feedback unit 2 may be substantially flush with the exterior surface of the central part 12 of the handlebar 1.

At least one of the side surfaces 26 may be provided with a positioning protrusion 23, for positioning the feedback unit 2 relative to the handlebar 1 and/or relative to other components, such as the handlebar body 9. In particular it is preferred that the positioning protrusion 23 is received by the accommodating space 11 of the handlebar body 9. The various segments 21 may each comprise their own optical element, such as a LED. It is conceivable that the segments 21, which may be light emitting surfaces 21 are visually separated, such that the number of optical elements that are turned on can be easily observed by a user. By changing the amount of the surfaces 21 that is lit up by the optical element of the feedback unit 2, an array of turned-on optical elements may be established.
Turning on more optical elements may for example represent a higher velocity, or a higher battery charge. The handlebar feedback unit 2 comprises an open part 24, which open part interrupts the annular shape of the feedback unit 2. Preferably the feedback unit 2 is configured for at least partially enclosing a part of the handlebar 1. Preferably, said handlebart and feedback unit 2 are at least partially coaxially oriented.

Adjacent to the handlebar is the feedback unit 2, wherein one sideward surface 26 of the feedback unit 2 abuts the end surface of the handlebar body 9. The exposed exterior surface 25 of the handlebar feedback unit 2 is substantially flush with an exposed exterior surface of the handlebar body 9. The bottom side 10 of the handlebar, in particular an end portion thereof, comprises a recessed channel 13. The recessed channel 13 is configured for guiding wires and/or connectors of the handlebar feedback unit 2. The grip 3 of the handlebar 1 may eventually slide over said end part of the handlebar 1 such as to essentially entirely cover the wires of the feedback unit 2. The wires extend from the handlebar feedback unit 2, through the recessed channel 13, and then bend backward in a cut-out part 14, and then enter the interior of the handlebar 1 via an opening 15 in the end of the handlebar. As such, the wires may easily enter the interior side of the handlebar 1, without requiring a hole to be drilled in the handlebar 1 surface for each wire since this may harm the strength of the handlebar 1.
