Have 3 Sondors together with my wife. The black X fold has about 15K miles accumulated with all original parts but the rear tire is pretty worn. Using it to run my border collie dog, Spotty in all four seasons in the past 3 years.
Yeah, the fold X is very comfortable on asphalt, getting the most use. The big bike is sitting in the basement mostly but has it purpose when off road and mud etc. Looks not as important to me but I am happy with all of them as long as reliable and practical.
