R&D team comments Designed and developed in the Swiss Alps by designer Alexandre Paux, the Bi 4 2 design brief was a tough one. To deliver the same high quality and great handling that our demanding professionals require, yet bring it onto the market at a competition busting price.
Alexandre explains how this was achieved.
“Tailoring a complex design to be economical to produce is just the sort of challenge I love. Making a clever and complex design, and then streamlining that design to meet the demands of the tandem professionals both with price and performance equals happy tandem op bosses and happy passengers."
