I'm still riding my 2015 Turbo X, bought in September 2016. I ride it three or four times every week; now for over a decade. It's on it's third battery, with the second covered under warranty. Front disc brake brake replaced with a Shimano unit. Current issue is the Clean Cockpit Turbo Display has failed. it's my second unit and it looks like it it is not available anywhere. I would love to buy one from anyone anywhere. Currently, the bike works but is in full turbo mode at all times.
