Bikes: Catrike 559 I own some others but they don't get ridden very much.
That was a standard design but that's all I know about it.

Looks like a clever (?) MTB design utilizing oversized specially-shaped top and down tubes and without a seat tube. There have plenty plenty of 'unusual' MTB frames over the years.

What I thought was a lug on the bottom was just the right pedal. Very strange design though.

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
The idea was that without the seat tube, there was some vertical flex to be had. In theory it made for a more comfortable ride. It also made for a less structurally sound design, but I have no idea if there were ever any issues. In any case, it's an example of another bright idea in practice.

Hi all
thanks for the insight. I am not familiar with modern bikes. The frame is bit large for me, so I was thinking of replacing it later with a smaller frame. If I find another smaller rigid frame, are the components mostly compatible? The bike is mostly for commuting 2km or so. Right now cost is the most important consideration. As is I can still use the bike after I adjusted the saddle, oiled and repack the bearings etc.
regards
