The Feelfree Overdrive is the modern evolution of pedal and powered kayak propulsion offering effortless speed, ease of use and adaptability. Designed to be retrofittable on most Lure 11.5, 13.5, and Lure II Tandem, the Overdrive is the only two-in-one system that offers forward and reverse pedal or power driven capabilities in one single unit when paired with the Motordrive. Engineered to last, the system is manufactured using cast aluminum and finished off with heavy-duty components. Paddle, pedal or power, the Overdrive system gives kayak anglers and recreational paddlers the flexibility to Feelfree all day long no matter where they choose to have fun!
