Sunny Health & Fitness Performance Smart Magnetic Recumbent Elliptical Cross Trainer

If you want recumbent comfort with more elliptical-style movement, the Sunny Performance Smart Magnetic Recumbent Elliptical Cross Trainer (SF-RBE420035) sits in a rare middle ground. You get a seated, back-supported position — same as a standard recumbent — but the pedal stroke traces an elliptical arc rather than a circle, and long moving arm handles let you work upper and lower body from the same seated position.

This guide looks at how the SF-RBE420035 fits into small homes and flats, focusing on noise, footprint, comfort and who it's best for.

What makes it quiet enough for small homes

The SF-RBE420035 uses an 8-level magnetic resistance system with no belt drive rubbing or friction pads — the two loudest sources on cheaper machines. Because your feet stay on the pedals throughout the elliptical stroke (rather than lifting and stamping like on a treadmill), there's essentially no floor impact either. The only sound most owners report is a soft hum from the flywheel bearings and the very quiet SunnyFit app-connected console.

In practical terms, that means you can use it while someone else watches TV in the same room, and — on the ground floor of a typical UK home — it won't transmit noticeable vibration to a neighbour through party walls or upstairs floors.

The Performance Smart Magnetic Recumbent Elliptical Cross Trainer is likely to suit:

• People who want recumbent comfort but a more varied stride than a circular pedal

• Older users and anyone in rehab who needs low-impact, joint-friendly cardio

• Buyers who want light upper-body work from a seated position (moving arm handles included)

• Small-home users who can dedicate a corner permanently — the machine has a fixed footprint and doesn't fold

• Anyone who wants app-connected workouts (SunnyFit Bluetooth is built in)

The Performance Smart Magnetic Recumbent Elliptical Cross Trainer is less suitable for:

• People who want high-intensity, spin-bike-style intervals — this is a low-impact machine by design

• Anyone who needs to fold the machine away completely between sessions

• Very tall users (over 6ft 4in / 193cm) — the stride length may feel short

How it compares to the other Sunny recumbents

The three Sunny Health & Fitness recumbents we cover at QuietFit Lab share the same base frame but offer different accessory tiers. The Cross Trainer is the outlier:

• The Sunny SF-RB4616SMART base recumbent and the 16-Level model with Workout Bands both use circular pedals — a standard recumbent bike motion.

• The Sunny SF-RB420032 Arm Exerciser model adds moving arm handles but still uses circular pedals.

• The Cross Trainer (this listing) is the only Sunny recumbent with an elliptical stride pattern — the pedal motion is oval rather than circular, which many users find smoother and more natural for longer sessions.

If you're not sure which Sunny to choose, our best quiet recumbent bikes guide walks through all four side by side.

Frequently asked questions

Is the Cross Trainer better for seniors than a standard recumbent bike?

For many older users, yes. The elliptical stride feels smoother than a circular pedal for people with knee or hip stiffness, and the moving arm handles let you keep the whole body warm and moving without needing to stand up or transfer to another machine. The step-through frame and back-supported seat are the same senior-friendly design as the rest of the Sunny recumbent range.

How much floor space does it need?

The SF-RBE420035 has a slightly larger footprint than a standard recumbent because of the elliptical arm mechanism. Expect around 63 × 27 inches (160 × 69 cm) of floor space. It's still smaller than most upright treadmills, and low enough that it fits under a window sill or against a living-room wall, but it's not something you can fold away between sessions.

Is it quiet enough for an upstairs flat?

Yes. Because you stay seated and the resistance is magnetic, there's minimal floor vibration — one of the quietest cardio machines you can put in a first-floor flat. Owners in shared homes typically report they can use it while others are asleep in adjoining rooms.

Does it connect to a phone or fitness app?

Yes — Bluetooth connects to the free SunnyFit app for guided workouts, progress tracking, and console readouts on a phone or tablet. The app is optional; the console works standalone too.

Can I use it just for legs, or just for arms?

Yes. The moving handles are decoupled from the pedals, so you can pedal with the handles locked, or exercise only the arms while resting the legs. Useful for rehab work, or on days when one part of the body needs to rest.
