Studio Pro S3 Indoor Spin Bike

This bike suits people who already like hard cardio, or who want to follow along with an indoor cycling class on a phone or tablet. It is the right bike if you want to get out of the saddle, sprint, and climb.

It is a heavier, more serious frame than our folding and upright bikes. It stays where you put it. The maximum user weight is 150 kg.

Flywheel weight is the first thing to look at. A light flywheel makes the pedal stroke feel choppy. A heavier one, like the 11 kg wheel on the Studio Pro S3, smooths the stroke out and lets you stand up without the bike feeling like it wants to stop.

Adjustability is the second. A spin bike you cannot fit is a spin bike you will not ride. This one micro-adjusts the seat and the handlebars, so you can set your knee angle and your reach properly rather than settling for the nearest hole.

Pedals and stability come third. Caged pedals hold your feet at speed, and the wide, weighted base keeps the frame steady when you climb out of the saddle.

Finally, the screen. This bike has a phone and tablet mount rather than a built-in display, which keeps the price down and lets you use the app or class you already pay for.

Free UK delivery, shipped to your door by a tracked courier. A spin bike is the heaviest thing we sell, so it comes on a pallet or a two-person service, part-assembled, with the tools you need in the box.

The heavy frame arrives built. The seat, handlebars, pedals and stabilisers attach at home, with clear instructions supplied. It helps to clear a space and to have a second person on hand to move the frame.

Typical delivery window: [confirm]. The courier agrees a day with you first and sends tracking before it arrives.

This bike does not fold. Decide where it lives before it arrives. It needs a level floor and enough room to stand up on the pedals without hitting a light fitting or a shelf.

Put a mat underneath. It protects the floor, catches sweat, and cuts the noise carried into the room below, which matters in a flat.

Wipe the frame and the bars after every ride, because sweat drips onto the frame directly on this style of bike. Check the pedals and the seat clamp monthly, and keep the flywheel area clear of dust.

Against our folding and upright bikes, the Studio Pro S3 is the one you buy to work hard. It costs more, weighs more, and does not tuck away, but nothing else in the range gives you a standing climb.

Cycling is also gentler on the knees than it looks. A peer-reviewed study of cycling and knee osteoarthritis notes that cycling imposes lower knee joint loads than walking, stair climbing and common resistance training exercises^[2]. You can push hard on a bike while asking less of your knees than a run would.

The intensity is sustained, too. In the same indoor cycling study, riders stayed at hard intensity from the 10 minute mark to the end of the 45 minute class^[1], which is why two or three rides a week go a long way.
