I gave these two to a couple of my younger brothers but have donated several others to local kids and the charity thrift store. But I really enjoyed rebuilding (that word should be in caps!) a schwinn 3wheeler. An local waitress at a cafe I frequent was dejected over a recent large loss. Her house had completely burned and the pair was living in a borrowed RV. But her only complaint was about the disappointed grandkids who enjoyed riding the bike (the only thing that survived the fire) but was then backed over by the fire truck. It took quite a bit and a lot of work but remains my favorite rebuild ever. She told them Santa Claus fixed it.
