INTRODUCTION
Congratulations on the purchase of your new Response U6c Exercise Bicycle. You have made a smart choice and are about
to enjoy one of the most effective and technically-advanced methods of cardiovascular exercise available today.
Founded in 1991 as an off-shoot of the legendary bicycle company, Diamondback Fitness was in many ways a complimentary
addition to the Diamondback brand. One might even say this extension grew as a natural evolution…an evolution from
classic outdoor bicycle usage, toward indoor-based cycling and cross training. It turns out that many fitness enthusiasts were
searching for ways to maintain conditioning during times of inclement weather or were simply looking for new and different
cross-training options.
This trend still continues today, twenty years later, as the strong Diamondback brand resonates with both the boomers who
grew up with the bicycles, as well as the younger generations riding them today.
Diamondback Fitness continues to build upon this legendary brand identity by offering the cardio enthusiast a full line of
upright exercise bicycles, recumbents, and elliptical trainers, each offering superior value and quality in an intuitive and
visually-appealing design. Let’s just say, we are already planning our next twenty years.
Thank you for choosing Diamondback Fitness.
