first off I saw a couple people have the motor quit, both, the manufacturer of the bike replaced for them. I have also seen a couple where the nylon gear went out. As for it being a odd question it is not. Currently a Levo can be had for a bit over 4000, or used for under 4000. The Luna X1 is 3650 and the Apollo is 4900. Soo really the price difference is not all that great from a X1 to a Levo, 25% on a purchase of this magnitude is not the end of the world if there is a difference in reliability. Now I am not claiming there is a difference. I am doing just the opposite, I am asking those on this forum to tell me what their experience has been, because I am considering a Luna with a M600 drive system, but I do not want to find out after that I did not ask the question here. Instead of jumping me for asking why not tell me your experience and help me. The fact that I currently own two Bfang converted bikes should tell you the way I lean when it comes to E-bikes. When I built my Kona I was offered a slightly used Levo for maybe 1000 more than my Kona and the conversion cost me. the Kona is just much more what I was looking for. Now I have another goal, and there are 3 options, conversion, Luna spec built, or major manufacturer. ( my least favorite of the list). As I said, I am looking for info, not criticizing...
