Four women cycle across Australia on a custom quad tandem bike for charity

Four women are cycling across Australia on a custom quad tandem bike for charity, baffling mechanics with its unique design. The bright red, 3.8-meter-long bike has four seats, eight pedals, and 80 spokes. It was custom-made in the US for a 2023 charity race and shipped to Australia for the current journey. The riders are raising money for suicide prevention charity Gotcha-4-Life, facing challenges with the bike's wide turning circle, side winds, and frequent maintenance issues.
