This popped up on our local FB MP. It was listed a womans bike with Trek frame. I thought it looked interesting and did an image search to find out it was a Trek Lime with an automatic 3 speed. I did a little reading on it and, since I'm a glutton for punishment, I went to see it. Pumped up the tires and took it for a ride. I did get it to shift and on the strength of that I bought it. The seller was gifted this bike by a neighbor and thought it was a cruiser, had no idea about the shifting and also no idea what the insert in the frame was about. It was gummy on both sides, so I wonder if it was used for a "rolling billboard" and someone had pulled the stickers off. I have found a page on the transmission by Park tool and a video about taking the rear wheel off to repair a flat. Has anyone had one of these and have any hints, hacks, or "gotchas" to share? Thanks!
