It's a minus one star. Wish I'd read these reviews before buying Horizon gym bike. Lasted 15 months use by two elderly light weight people before grinding to a halt. Like many others apparently once you've spent the money Powerhouse Fitness don't want to know. No after-sale service, no offers of any kind of assistance other than "contact the manufacturer". Manufacturer Johnson Fitness response - "contact the seller", so no service organisation there either. Hundreds of pounds down the drain, just what two pensioners really need. I do have proof of purchase but prefer not to share it, though I will do so if anyone specifically asks.
