Hi so i was wondering if anyone here owns a pedalpower quad tandem bike ? if so is it coupled ? does it break down into a triple and a tandem ? If so how much did it cost ? what accessories would you recommend ? how many brakes would you recommend ? If your quad is a fixed bike with no couplers how much did it cost ? is it a classic steel or aluminium ? Last but no least do you enjoy riding the bike ?
