Mine is a Volt Pulse X bought in 2017. The spokes on the rear wheel started to ping they were quite thin but the shop I bought it from replaced them without charge. It might be at the time they were relatively new and not quite up to production values. Hopefully now they are, my bike is still going strong and the chain is unchanged. Though it has to be said I was stopped by a team of people checking the bike and offering advice on security and theft prevention. They checked the chain and said it should be looked at. At that time I might have travelled 5000 or more miles so probably to be expected. The fastest I can reliably say I've got was 26 mph going down hill and I can say I had no issues with stability. One time the odometer said I got to 33mph but I think it may have been set to kilometres. As much as I have tried to see if I could do it again London roads don't allow it. Choosing a bike is hard to do even though most stores allow you to try a bike out. It's impossible to try it under all road conditions and make an informed decision. I don't know what toe overlap means ( google it Frank ) but I still have all of mine. Yeah I would agree possibly over priced but I think it can be said of a lot of makes. If I was to buy a new bike I would use £2000 as an average for a good bike. According to the shop I bought mine from they said there wasn't a great profit for them. They would say that wouldn't they. I am at 6800 miles now and hopefully with the increased traffic on the roads since covid " it's really bad " I will get a good few more miles out of the bugger yet.
