FREQUENTLY ASKED QUESTIONS ABOUT THE RB505
What muscles does the RB505 work?
The RB505 combines dual-action moving arms with recumbent pedaling to engage both your upper and lower body. Your legs and glutes work through the pedal stroke, while the moving arms involve your shoulders, chest, back, biceps, and triceps for a more complete full-body cardio workout.
Is a recumbent bike with moving arms better than a standard recumbent bike?
It can be a better choice if you want full-body cardio. A standard recumbent bike mainly trains the lower body, while the RB505 adds synchronized moving arms so your upper and lower body can work together from the same comfortable seated position.
Can I ride the RB505 without using the moving arms?
Yes. You can hold the fixed side handlebars whenever you want to focus on lower-body cardio. When you want a full-body workout, use the moving arms together with the pedals.
Does the RB505 burn more calories than a standard recumbent bike?
Using the moving arms may increase total muscle involvement compared with leg-only riding, which may increase calorie burn under similar workout conditions. Actual results depend on your body size, resistance level, pace, workout duration, and overall fitness level.
Is the RB505 suitable for heavier riders?
Yes. The RB505 supports users up to 450 lbs and uses a reinforced steel frame with wide stabilizers to help keep the bike steady during both pedaling and upper-body movement.
Is the RB505 suitable for seniors?
Many older adults may find the RB505 easier to use because of its low step-through frame, supportive recumbent seat, wide pedals, and low-impact motion. Anyone with a medical condition or recent injury should speak with a qualified healthcare professional before starting a new exercise routine.
What's the difference between the RB505 and RB408?
The RB408 is the more affordable option for riders who want a recumbent bike with arm exerciser support. The RB505 is the premium upgrade, with dual-action moving arms, a heavier flywheel, a ventilated mesh backrest, and a reinforced 450 lb frame for a smoother and more stable full-body ride.
How quiet is the RB505?
The RB505 uses magnetic resistance and a belt-drive system to keep operation quiet. It is suitable for apartments, shared living spaces, and early-morning or evening workouts when lower noise matters.
