Sunny Health and Fitness Indoor Studio Cycle Pro Exercise Bike with 18 KG (40 Pound) Flywheel - £100.80 Delivered @ Amazon

Hilarious

The price is suspiciously good for a bike that is really popular with many and many have turned it into a poor person's Pelaton bike, by, for instance, adding a stick-on-able cadence sensor, heart rate monitor, even power measuring pedals. It takes the price up but still a tiny fraction of a Pelaton bike that, though obviously in many ways better, the Sunny still gives you a really good workout. I think quality control is a bit suspect but that seems to apply to a lot of spin bikes, whether they are ultra budget ones, like this, or expensive ones. I heard that Sunny don't warranty the bike in the UK but I don't see how that's legal, so I doubt that's true or well-explained and you can always return it to Amazon if faulty within the return period, so I think at £100, it's worth a shot and a fairly astonishing bargain, to boot.

To reduce noise, the advice seems to be add 'mineral oil' to the friction pads that control the level of resistance. A lot of good videos on that bike.

Why not? They're like that so you can adjust it forwards and backwards.
