Just got my LT xtr. Unfortunately it was delivered with the euro 15 mph tune so i actually used my legs for a week until the dealer sorted it. I like it. The ep8 clunk seems to be muted, perhaps by the frame design that encompasses the motor. It's a smooth ride, not quite as much power as the bosch in the rail but i feel comfortable going a bit quicker than the rail. A bit less twitchy with a light feel to it. The main thing though is the efficiency of the ep8. I can actually use it like a push bike. Yesterday i climbed almost a thousand feet with the motor off, unheard of for me on the rail or my pos levo
