Picked this up today. I have no clue what it is. Heavy duty spokes, small chainring, Bendix 76 rear hub, Shimano front hub. The head badge was extremely hard to photograph but I believe it says "Trail Mate"? It kind of looks like a Worksman or something similar. I can't seem to find a serial number yet. Very odd design and for $15 I couldn't pass it up (thanks Dave for the bikes)! I think it has a lot of potential. Hopefully someone recognizes this!
