FREQUENTLY ASKED QUESTIONS
Is the RB505 good for knee pain or joint issues?
Yes — thanks to its low-impact dual-action design, step-through entry, and adjustable resistance, the RB505 is ideal for joint-friendly training and recovery programs.
How quiet is the RB505? Can I use it in an apartment at night?
The RB505 features a magnetic resistance system and belt drive engineered to operate under 15 dB. You can ride while others sleep without disturbance.

What's the difference between RB505 and RB408?
While both offer full-body dual-action workout, the RB505 delivers a higher weight capacity (450 lbs vs 400 lbs), wider footprint and longer inseam range—ideal for heavier users or taller riders seeking maximum stability. The RB408 offers excellent value under $500 for standard riders.
