| Resistance levels | 16 |
| Flywheel | 6 kg heavy duty cast iron magnetic flywheel |
| Drive system | Belt Drive |
| Programs | 12 preset programs, 1 Watts program, 1 HRC program, 1 custom user program |
If you carry knee or lower back concerns and want a low, stable seated ride, the RC-300 puts you in an ergonomic seat with lumbar support and 16 levels of automatic magnetic resistance to dial in effort. The 6 kg cast iron flywheel and quiet belt drive keep the pedal stroke smooth for 30 to 60 minute sessions.
It suits older riders and anyone easing back into cardio at home, with a quick-release seat that slides forward and back to fit household members from 55 cm seat height upward and a max user weight of 150 kg. The large LCD console runs 12 preset programs plus Watts, HRC and a custom user program without needing your phone.
The step-through frame is the detail I'd flag first: the seat slides on a quick-release forwards and backwards, so short and tall riders swap in seconds without tools. Genuinely handy in a shared household.
The 6 kg flywheel keeps things smooth for steady cardio, not flat-out sprint intervals. The standout for me is the automatic magnetic resistance across 16 levels, so you dial effort straight from the console mid-ride.

A quick look at the RC-300 before you commit tells you more than any spec sheet can. You get to see the step-through frame, the seat adjustment and the console layout in real time.
What this means for you: If you are buying without visiting a showroom, the video answers most of the questions a photo leaves open.
The seat is the reason people actually finish their sessions on a recumbent bike. A padded, contoured seat with a breathable mesh backrest keeps you supported through a 45-minute ride without the pressure points you get from an upright saddle.
The mesh back lets air move, so your back stays cooler on longer efforts.
What this means for you: In my experience, seat comfort is what keeps beginners coming back day after day rather than quitting in week two.
The backrest includes dedicated lumbar support that fills the natural curve of your lower back. That means you sit upright rather than slumping, which helps you hold good posture as you tire late in a ride.
What this means for you: For anyone who finds an upright bike hard on the lower back, this is the feature that makes a recumbent worth the extra floor space.
The handles beside the seat fold up out of the way, so getting on and off the bike is simple. That matters most for older riders or anyone with limited mobility who needs a clear path into the seat.
What this means for you: I have set clients up on machines like this where getting on and off was the whole battle, and a clear step-through path solves it.
The seat slides forwards and backwards on a quick-release lever, so you can set the leg reach in seconds and different family members can swap without tools. The front handles also adjust in angle to suit your reach.
What this means for you: A wide 58 cm to 75 cm leg-reach range means most adults in one household can share the same bike comfortably.
Resistance is controlled electronically through 16 magnetic levels, so you change effort from the console rather than reaching for a knob. Because it is magnetic and belt-driven, there is no friction pad to wear out.
What this means for you: Automatic resistance is what lets the preset programs adjust effort for you mid-session, which is where interval training gets useful.
Because the bike sets resistance itself, the console can drive your workout instead of you managing it. That opens up structured training that would be fiddly to run by hand.
What this means for you: When I coach first-time riders, hands-off resistance keeps them focused on cadence and breathing instead of the machine.
The console has a built-in holder for a tablet or book, positioned above the LCD display so it does not block your workout data. A USB port keeps a device charged while you ride, and there is a 3.5 mm AUX input for audio.
What this means for you: Being able to watch something while charging your tablet is a small thing that quietly adds ten minutes to most sessions.
The 6 kg cast iron flywheel carries momentum through the pedal stroke, so the pedalling feel is smooth rather than jerky. Paired with the quiet belt drive, it runs quietly enough to use while others are in the room.
What this means for you: A heavier flywheel is what separates a smooth ride from a choppy one, and that is the bit I would stake this recommendation on.

Effort: one person can manage it; commonly 45 minutes to 2 hours, depending on the model. Exact time depends on your experience. The unit arrives in a 53.5 kg carton, so having two people available to unbox and position it is recommended. Tools: spanner / wrench (bolts and fixings included).
Very quiet. The belt drive and 6 kg magnetic flywheel mean there's no chain slap and no friction pad wearing down, so the main sound is the belt turning smoothly. You can ride it while others sleep, watch TV at normal volume, or take a phone call mid-session. Magnetic resistance is the reason it stays this quiet at every one of the 16 levels.
The EKG hand pulse sensors handle casual use, giving you a rough read when you grip the front handles. But you have to hold still, which breaks your rhythm. If you want accurate heart rate zones for weight loss or aerobic training, pair a chest strap (around $80) so you can pedal freely and still trust the numbers.
The seated, backrest position suits anyone who wants a comfortable low-impact ride: returning to exercise, carrying extra weight, or just wanting to read or watch a tablet while they train. The mesh backrest with lumbar support takes strain off your lower back. Max user weight is 150 kg, and the seat adjusts with a quick-release for riders of most heights.
The assembled footprint is 170 cm long, 66.5 cm wide and 110 cm tall, so it fits under any standard ceiling with room to spare. Allow a little clearance around it for getting on and off. Transport wheels let you tilt and roll it out of the way, and at 53.5 kg one person can reposition it without much fuss.
One person can put it together, usually somewhere between 45 minutes and 2 hours depending on your experience. You'll need a spanner or wrench, and the bolts and fixings come in the box. Build it close to where you want it to live.
You get a 12-month parts replacement, handled locally by us rather than an overseas manufacturer. It also carries the 100-day money-back guarantee, so you can ride it at home for a genuine stretch and return it in as-new condition if it isn't the right fit. Just check the badge is on this page.
It ships boxed by freight courier with live tracking, packed at 166.5 cm long. Check the carton on arrival before signing. If anything is damaged or a part is missing, take photos before unpacking and email support@cardioonline.com.au within 48 hours. We lodge the freight claim and organise replacement parts or a full unit. You never deal with the courier or manufacturer yourself.

I was advised by a physio that a Recumbent bike would suit my needs so I set about researching. I chose Lifespan RC-300 from Cardio Online Superstore and I am thrilled. Even for a 66yr old I managed to assemble it and foiling the process relatively smooth. It is heavy so be aware of that though. So far my process is steady, I am slowly building up my fitness regime as previously advised. the bike is so quiet it’s amazing. I am using it daily and thus far love it. The company was perfection during my purchase and the delivery service amazing, they even called to confirm delivery. Anyone wanting to start their fitness journey should check out Cardio Online Suoerstore. You won’t be disappointed!!
My recent purchase of a RC300 was excellent. The machine itself is beautifully engineered, silky smooth to use and performs well above-my expectations.
Cardio On Line were magnificent to deal with. Jasper dealt with delivery issues in a very professional manner and ensured that the courier company fully understood my needs. I was very encouraged with his professional caring approach. A big thank you to Jasper and to Cardio on Line
