The Sunny Health & Fitness Recumbent SF-RB4601 is an entry-level model with a walk-through recumbent frame. Unlike many of the models in our best exercise bikes (opens in new tab) guide, there are no workout presets on-board here, but it does have eight levels of magnetic resistance you can adjust with a tension control knob. This lets you increase the intensity of your workout to burn more calories and tone the muscles in your legs.
To track your calories burned, consider using one of the best fitness trackers (opens in new tab). Fitbit is our top choice here, and they are often on sale among the best Amazon Prime Day Fitbit deals (opens in new tab).
The Recumbent SF-RB4601’s handgrips are seat-mounted and have pulse sensors to help you keep your heart rate in the target zone. Unlike the Schwinn 270 Recumbent (opens in new tab), our favorite recumbent, the Sunny Health & Fitness machine doesn’t have a second pair of hand grips at the console, but its seat is reclined enough that you likely won’t miss them.
Like most of the exercise bikes we tested, this one has a maximum user weight of 300 pounds. Its foot pedal style is self-leveling, and it accommodates users with inseam measurements between 23 and 33 inches. Most manufacturers provide user height parameters versus inseam measurements, with 5’1” to 6’4” being a common range.
One feature unique to this bike is its patented EASY Seat system, which allows you to make seating adjustments without having to rise from the machine. You simply flick a handle at your side. This exercise bike also has adjustable pedal straps, along with textured pedals for better foot grip.
Part of what keeps the price of the Sunny Health & Fitness Recumbent below $199 is that it doesn’t have many of the same comfort and convenience features as more expensive exercise bikes. First, it isn’t Bluetooth connected. Its digital monitor displays time, speed, distance, calories and pulse as you ride, but no user profile or tracking information is stored. It also lacks an accessory holder, water bottle holder, workout fan, speakers and aux port.
The fully loaded Nautilus U618 (opens in new tab), which is our favorite upright machine and best overall pick, has all these features. It also costs $200 more than the Sunny Health & Fitness bike. Two comparatively priced machines are the Marcy Recumbent ME 709 (opens in new tab) and the XTERRA Fitness FB350 (opens in new tab) – an upright and our choice for best value.
The Recumbent SF-RB4601 weighs 58 pounds and has dimensions of 56 x 29 x 38 inches (length, width, height). Sunny Health & Fitness provides a three-year warranty on its frame and 90 days of coverage on parts and components. Customer service is available by phone and email.
