I bought a spin bike because we’ve just had a baby and I can’t see me getting out on the bike anytime soon. And my knee is knackered so when it flares up I can stop and hobble indoors rather than finish the ride.
Wasn’t expecting the fixed flywheel at first; nearly threw me over the bars!
I went for one with magnetic resistance rather than friction. Was a bit more than I had wanted to spend upfront, but figured I’d get it back in th longer term by it being one less thing to service. All good so far. Smooth and quietish.
I missed out on a mint one from a private sellet on ebay, so ended up getting mine from a dealer that resells used gymn kit, via ebay. Think they were based in Hinckley. fitkit-uk maybe? Huge unit packed to the rafters and stock seemed to turn over quite well when I was looking.
