Control assembly for a wireless electromechanical bicycle shifting system
A bicycle control assembly may be provided for operating an electromechanical gear shifting device. The control assembly includes a graspable housing mountable to the bicycle, a power supply connected to the control assembly disposed in the housing, a first operating member movably connected to the housing, and electronic componentry disposed on the first operating member. The electronic componentry may include an electrical switch, a controller in communication with the electrical switch and configured to generate a signal to change a shift position of the gear shifting device responsive to an input from the electrical switch, and an antenna in communication with the controller and configured to send the signal. The control assembly may also include a cable extending from the housing to the first operating member connecting the power supply and the electronic componentry.
1. A bicycle control assembly for operating an electromechanical gear shifting device, comprising:
a graspable housing mountable to the bicycle, the housing including an internal compartment;
a shift member movably connected to the housing, the shift member including a distal portion and a proximal portion, the proximal portion movably supported by the housing; and
a power supply disposed in the compartment,
wherein the bicycle control assembly has a centerline and the power supply is oriented parallel to the centerline.
2. The bicycle control assembly of claim 1 , further comprising:
a housing cover configured to provide access to the internal compartment.
3. The bicycle control assembly of claim 1 , further comprising:
an electrical switch disposed on the shift member, wherein the electrical switch is disposed at the distal portion of the shift member.
4. The bicycle control assembly of claim 3 , further comprising:
a controller in communication with the electrical switch configured to generate a signal to change a shift position of the gear shifting device responsive to an input from the electrical switch; and
an antenna on the shift member and in communication with the controller to send the signal.
5. The bicycle control assembly of claim 4 , wherein the distal portion includes an internal compartment and the antenna is housed within the internal compartment of the distal portion.
6. The bicycle control assembly of claim 1 , wherein the power supply is a coin shaped battery.
7. The bicycle control assembly of claim 1 , wherein the power supply is positioned on a front side of a holder that holds and electrically contacts the power supply.
8. The bicycle control assembly of claim 1 , wherein the housing is of a one-piece construction.
9. The bicycle control assembly of claim 8 , wherein the housing is formed of an injection molded thermoplastic.
10. The bicycle control assembly of claim 1 , further comprising:
an electrical switch disposed on the shift member; and
a cable that electrically connects the power supply with the electrical switch.
11. The bicycle control assembly of claim 10 , wherein the cable extends along the interior of the shift member.
12. A bicycle control assembly for operating an electromechanical gear shifting device, comprising:
a graspable housing mountable to the bicycle, the housing including an internal compartment, a top surface, a bottom surface, a first side surface and a second side surface;
a shift member movably connected to the housing, the shift member including a distal portion and a proximal portion, the proximal portion movably supported by the housing;
an electrical switch disposed on the shift member;
a controller in communication with the electrical switch configured to generate a signal to change a shift position of the gear shifting device responsive to an input from the electrical switch;
a power supply disposed in the compartment and providing power to the controller and the electrical switch; and
a housing cover configured to provide access to the internal compartment, and the housing cover is attached to one of the first side surface and the second side surface of the housing.
13. The bicycle control assembly of claim 12 , wherein the housing cover sits flush with the at least one first side surface or the second side surface of the housing.
14. The bicycle control assembly of claim 12 , wherein the power supply is configured to be installed through the at least one first side surface or the at least one second side surface of the housing.
15. The bicycle control assembly of claim 12 , wherein the controller is housed within the internal compartment.
16. The bicycle control assembly of claim 12 , wherein the housing cover is held in place on the housing with fasteners.
