ABSTRACT:
An electronic instrument is mounted on a handlebar of a bicycle. An instrument carrier is fastened to the handlebar. The instrument itself is engageable with the instrument carrier for holding engagement. A signal receiver is fastened to one leg of a fork which carries a bicycle wheel. The receiver is opposite the bicycle wheel. A signal inducer is mounted on a spoke of the bicycle wheel. The signal inducer generates signals within the signal receiver. These signals are supplied from the signal receiver by a cable to the instrument carrier. The instrument carrier is provided with contacts. Complementary contacts are provided on the instrument. When the instrument is engaged with the instrument carrier the electrical contacts of the instrument carrier and of the instrument come in mutual electrical engagement. At least one of the contacts is provided on a silicon rubber block which is elastically deformable when the contacts of the instrument carrier and the instrument are brought in electric connection.
