Digital harness version C-BS for button or switch control


All electronic boxes on the market reduce the amount of required cables on a bike. They make installations simpler and 
fault finding easier. However, it´s surprising how much wiring remains on the bike, what result in a typical installation time 
between 10 and 20 hours. 

The digital harness C-BS ("BS" stands for switches and buttons) for the bike control via push buttons and switches is an 
universal harness, what contain 2 small control boxes. The control boxes "talk" together via a thin serial bus cable. The switches, 
push buttons and power cables are wired direct to the nearest box. This reduces the amount of cables and the installation 
time significant in a typical bike installation. All outputs have integrated led´s what allow an easier testing while the installation. Some useful options are integrated. You can control your complete bike electric just with 2 buttons, without the need to learn complicated button combinations. 


The C-BS harness recognizes automatically a connection with an optional available handle bar adapter what help to reduce a few cables in the bike. The adapter could  be used for the control in showbikes what run not on public streets. It need good quality momentary buttons, a good ground connection and a stabile main voltage. Don´t use it for bikes what run in public traffic. However the handle bar adapter is available under "accessoires".
