If you want a low, step-through cardio machine for gentle indoor sessions at home, the LSG RB-100 seats you back in a supported position on an adjustable comfort seat with 8 magnetic resistance levels and a quiet belt drivetrain. The LCD display tracks time, speed, distance and calories, and the cast iron flywheel keeps each stroke smooth for users up to 120 kg.
It suits older adults and anyone easing back into regular movement, with an adjustable arm exerciser that brings the upper body into each session. At 28 kg with built-in transport wheels, one person can roll it between rooms and tuck it away after a workout.
The step-through frame is what sells me here: clients who can't swing a leg over an upright just sit and ride. The 8-level magnetic resistance suits steady, low-effort cardio.
With a 120 kg user limit and a light 28 kg build, it isn't for hard interval work. The arm exerciser is the standout, giving you gentle upper-body movement alongside the pedalling.

The magnetic resistance system pairs with a heavy-duty cast iron flywheel to keep each pedal stroke even and quiet, so there's no jerky catch as you pick up pace.
Eight resistance levels give you room to start gentle and build up as your fitness improves.
What this means for you: You can train in a quiet room without disturbing anyone, and dial resistance up one level at a time as you get stronger.
The recumbent design seats you back with support through the lower back, and the comfort seat adjusts to suit different leg lengths.
Strap pedals hold your feet in place so your focus stays on the pedal stroke rather than keeping your feet from slipping.
What this means for you: A few people of different heights can share the bike and each find a comfortable fit.
The LCD display shows your four core numbers at a glance, so you can hold a steady pace or chase a distance target without guessing.
What this means for you: Watching distance and time tick over is a simple way to stay consistent and see progress session to session.
The included arm exerciser lets you add upper body movement alongside your pedalling, so you can work arms and legs in the one session.
It adjusts to suit your reach and seated position.
What this means for you: On days you want more than a leg workout, the arm exerciser gives you a way to get the upper body moving too.
Built-in transportation wheels let one person tilt and roll the bike rather than lift its full weight, so it's easy to shift out of the way after a session.
At 28 kg net (31.5 kg boxed), it's light enough to shift on your own.
What this means for you: If the bike lives in a shared space, you can tuck it against a wall between workouts and roll it back out when you need it.
The frame uses heavy-duty tubular steel to stay stable while you pedal, holding firm rather than flexing under a harder effort.
It's rated for users up to 120 kg.
What this means for you: A steady frame means you can push the pace without the bike rocking underneath you.

It ships in a single box measuring 119 cm by 25 cm by 57.5 cm, with a gross weight of 31.5 kg, through our network of over 190 depots. It's manageable, but a second pair of hands makes getting it inside easier. Request a quote and we'll confirm the timeframe to your postcode.
Take photos before you start assembling and email support@cardioonline.com.au within 48 hours of delivery. We'll lodge the freight claim, organise replacement parts or a full unit, and stay across it until you're riding. You don't chase the courier or LSG directly, that's our job to sort.
The manual walks you through 8 assembly steps and strongly recommends two or more people for the build. The tools you need and all bolts and fixings come in the box. The bike arrives partially assembled, so the job is mostly fitting the seat, posts, console and pedals.
It comes with a 12 month parts replacement warranty, handled by us locally. If the product page shows the 100 Day Money Back Guarantee badge, you have 100 days to return it as-new, disassembled and in the original packaging with all parts. We refund the product price and your original delivery fee, no restocking fee. We book the return freight; you cover that cost.
The footprint is 120 cm long, 63 cm wide and 103 cm high, so it slots into a corner or a spare room without dominating it. At just over a metre tall it clears any standard ceiling easily. The built-in transportation wheels let you tilt and roll it out of the way between sessions.
The recumbent design suits anyone who wants a supported, upright-back riding position rather than hunching over handlebars. The step-through frame makes getting on and off easy, and it handles users up to 120 kg. Best for walkers, beginners and anyone easing back into cardio who wants low-fuss, seated sessions at home.
It uses a heavy-duty cast iron magnetic flywheel with 8 resistance levels and a quiet belt drivetrain, so there's no friction pad to wear out. You adjust resistance manually across those 8 steps, which is plenty of range for steady-state cardio. The belt drive keeps it quiet enough for early mornings or shared walls.
No phone or app needed; the console runs on two AAA batteries. The LCD display shows time, speed, distance and calories as you ride, with a scan mode that cycles through them, so you can keep an eye on your session at a glance. There's also an adjustable arm exerciser if you want to add upper-body movement to your ride.
