Talk to a spin bike specialist| Flywheel | 20 kg Cast Iron, TrueSpin Balanced |
| Resistance | 32 levels, Automatic Magnetic |
| Warranty | 12 months parts replacement |
If you spin 4 or 5 times a week and want gym-grade feel at home, the Lifespan Fitness SM810 pairs a 20 kg cast-iron flywheel with 32 automatic magnetic resistance levels for a weighted, controlled ride. The belt drivetrain runs quietly and the frame carries riders up to 160 kg.
It suits dedicated indoor cyclists who follow structured sessions: it connects over Bluetooth to the Lifespan FitLink app, the seat adjusts up, down and fore and aft, and the handlebars adjust for height. Transport wheels and floor levellers make it easy to position on any floor.
What sets this one apart is the 20 kg cast iron flywheel with 32 automatic magnetic levels: steady, weighted momentum and precise resistance steps from the console knob.
The auto resistance adds a motor, so it needs a power point nearby. It connects to the Lifespan FitLink app over Bluetooth for structured interval sessions.

This is a studio-style bike engineered for hard daily use at home, with a 160 kg maximum user weight and a 20 kg flywheel on a steel frame for standing sprints.
The steel frame and heavy build mean it holds its line when you climb out of the saddle instead of rocking across the floor.
What this means for you: Heavier riders and intense sprint sessions are both handled without the frame feeling flimsy.
Magnetic resistance uses magnets rather than friction pads, so there is nothing to wear out and nothing to replace over time. The 32 levels give you fine control over how hard each interval feels.
You change the load by turning the knob on the console display rather than reaching down to the flywheel mid-ride.
What this means for you: You can dial in easy recovery spins or steep simulated climbs without breaking your rhythm.
A heavy 20 kg cast iron flywheel carries momentum smoothly through each pedal stroke, which is what gives a spin bike that road-like feel. The TrueSpin balancing keeps the rotation even rather than pulsing at speed.
What this means for you: The ride feels fluid at high cadence instead of choppy, which is the difference you notice most on long sessions.
The seat adjusts up/down (55 to 75 cm seat height) and fore/aft, and the handlebars adjust for height, so you can set a proper riding position rather than compromising on reach or saddle height. That range also makes the bike easy to share between people of different heights.
The Comfort Sport PU leather seat and dual-sided aluminium alloy pedals round out the contact points.
What this means for you: You can match the fit to your body, which is what keeps you comfortable past the 30-minute mark.
The large LCD tracks the numbers that actually guide a session: time, speed, distance, calories and resistance level. Keeping these in one clear view means you can pace intervals without guessing.
What this means for you: You can hold a target pace or build structured intervals off the data in front of you.
A belt drive runs quietly and needs no lubrication or tensioning the way a chain does, so maintenance stays minimal. The low noise matters if you ride early mornings or share walls with family.
What this means for you: You can train before work without waking the house or wearing out a chain.
The bike connects over Bluetooth to the Lifespan FitLink app, so you can follow structured training on your own device, and the console shows when Bluetooth is connected. A built-in device holder keeps your phone or tablet at eye level while you ride.
What this means for you: App pairing is optional, not essential. The console runs the ride on its own if you prefer to just train.
Setup is 7 steps in the manual, using the supplied 5 mm and 6 mm hex keys and wrench plus a Phillips screwdriver, with all bolts and fixings included. The carton weighs 60 kg, so have a second person to help lift it.
Transport wheels and floor levellers make it easy to move into place and keep steady on uneven floors.
What this means for you: Most of the build is bolting the stabilisers, bars, seat and pedals onto a frame that arrives with the flywheel fitted.
The SM810 is covered by a 12 months parts replacement warranty, and our Australian team handles any claim with you directly.
What this means for you: Keep up the manual's regular bolt checks, since skipped maintenance can void the cover.

Effort: 7 assembly steps in the manual. Tools: the 5 mm and 6 mm hex keys and wrench supplied, plus a Phillips screwdriver for the bottle holder screws (bolts and fixings are included).
The 32 levels of automatic magnetic resistance step up smoothly, and you change them by turning the knob on the console display, so there is no reaching down to a brake mid-ride. Paired with the 20 kg TrueSpin balanced flywheel, the feel is steady and road-like at the top end. In my experience, that smoothness matters most during intervals, when you want resistance to change instantly.
Yes. The SM810 connects over Bluetooth to the Lifespan FitLink app, and there is a device holder to sit your phone or tablet at eye level. The console still shows speed, time, distance, calories and resistance level on its own, so you are not forced to pair a device.
The SM810 suits committed riders who train regularly. The 160 kg maximum user weight and 3-piece forged steel crank handle hard, frequent sessions. The seat adjusts up/down (55 to 75 cm) and fore/aft and the handlebars adjust for height, so most adults can find a proper riding position. If you ride a few times a week and want durability, this is the one I'd point you to.
Assembled, the SM810 measures 116 cm long, 53 cm wide and 127 cm tall, so it fits under any standard ceiling and in most spare rooms or garages. It doesn't fold, and it needs a power point nearby for the console and resistance motor. Transport wheels let you tilt and roll it aside for cleaning, and floor levellers keep it steady on uneven surfaces.
There are 7 steps in the manual: stabilisers, handlebar post, handlebar, bottle holder, saddle, pedals, then plugging into power. The hex keys and wrench are supplied, and you'll want a Phillips screwdriver for the bottle holder screws. The frame arrives with the flywheel and drive fitted, but the carton weighs 60 kg, so have a hand for lifting it out.
The SM810 is covered by a 12 months parts replacement warranty, and our Australian team handles the claim with you directly, so you're not chasing anyone else.
