This is a Lehman Trike kit. Well I started to tear down the new to me trike in the front end to install Zook's rake kit I ordered yesterday and decide to check the rear brakes while I'm waiting. Low and behold I pooped off he left center cap and to my disbelieve I found only 3 lug nut hold the tire on and the forth hole looks like it was torched out and there was nothing there. So my ? is how do you raise the trike to get the wheel out to replace it and what rim will fit this trike and I might as well replace the tires while I;m there.Thanks in advance.
