This leg gives you another inch of clearance between your knees and the underneath side of your desk. At 10 inches the DeskCycle already has the lowest pedal height of all pedal exercisers. This leg drops it to 9 inches.
Note that it places the pedals closer to the ground. You will need to point your toes forward when pedaling the bike. This will keep your heels from hitting the ground.
This is easy to do unless you have a physical condition that prevents you from pointing your toes. See the link “How To Use” at the DeskCycle website for instructions on how to pedal the bike.
