I have a Brand X-Mini, It is the EXACT same bike as an SDG, but these bikes have a box reinforced upper frame, will not bend! Brand new plastics, I just took the bike completely apart, greased everything, replaced bad ball bearings in the head. IT runs great never had one problem changed the oil regularly never raced, just a toy. Will have pics up tom. Most who know of these bikes know they run great and rarely break. Asking $600.00 local only
