The Buzz

The Diamondback 510Sr recumbent exercise bike features a heavy 125-lb frame, a 14-lb flywheel, sealed bearings, and a Poly-V drive train. The quiet, frictionless eddy current brake system provides 16 increment levels of resistance.

The sculptured Comfort-Plus seats are extra wide for comfort and the molded backseat provides lumbar support. The step-through frame style allows for easy on and off, and the console and handlebar tilt for a customized fit. As an added bonus, all Diamondback Fitness models come with a free water bottle and holder.

The display is easy to use and takes you through the steps to set up a new exercise session. For example, it prompts you to enter your age and weight before the workout to determine accurate HR readings.

There are also QuickSet program keys to let you start your favorite workout with a single button, or of course, you can just get on your exercise bike and start to pedal in a manual mode. But with 20 different programs and 16 levels of resistance, you will want to take advantage of all the Diamondback 510Sr recumbent has to offer.

You can also take a look the 510Ub model as well, which is the upright counterpart to the 510Sr.  They are basically the same bikes with a few minor differences besides the seat itself.
