Hobie's new MD-180 reverse drive allows you to switch between pedaling forward and reverse, with the pull of a handle. Pull the green handle for forward pedaling. Pull the red handle to go in reverse. It's as simple as that! The new MD-180 design features lower profile fins that provide the same speed as the old ones. The MD180 Mirage Drive features Hobie's all-new 2017 Glide Technology so you can pedal faster and more efficiently. This is the model with the Turbo fins, so there is no need to purchase an upgrade kit.
