Love the bike. Fairly easy to assemble but my problem was the power cable broke very easily. First extraction of pin from machine resulted in pin breaking. So today I emailed Viavito. Within 2 hours they were on the phone to me. They apologised for the problem and ( despite me offering to pay for it as I broke it) they are sending me out a new one. Now that is great service and I cannot praise them highly enough. Also they asked if everything was ok with the bike. All in all its a great product and their customer service is first class. So well done to them. I'm loving the bike and good to know that I can get in touch if I need to.
