I purchased an air bike based on the reviews on their website, forgetting that businesses have complete control over those and like a naive fool, I purchased. Lesson learned. The bike turned up and appeared to be okay. Once we had it assembled it was very quickly apparent that it was broken. It didn't survive a single revolution and made a lot of awful noise. The belt wasn't attached to the inside and so, the fan wouldn't turn with the pedals as there was nothing connecting them. Had a closer look and sure enough the belt was completely off, the item was broken and I'm half convinced this was used before or had taken an almighty impact that resulted in the belt coming off. It's slightly scuffed on the outside and doesn't appear brand new. I don't believe a human could remove the belt without tools which makes me think it wasn't attached at any point. Since, support have been impossible to contact, their chat facility never has anyone on it, the phone lines don't appear to have anyone answering them, emails are ignored as are contact requests through their contact page. There's zero guidance on the instructions on how to get the belt back onto the bike, it doesn't mention it so I don't think it's supposed to come off and given how hard it is to get back on, I'd be surprised. It's amazing because each time I visit this website to try to contact someone, I get automations to purchase more products and sales advisers reach out to me by email but nobody is interested in helping. Whatever you do, don't buy from this company. There are many other options.
