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."
And we did it: Just give it a try yourself. Contact your dealer or fill in the table, we will link you with the right person to show you the glider. -
