That's funny you say that Tokolosh because I was wondering if I was just crazy... but I can never seem to stand on the pedals. It just doesn't feel right when I try.
I haven't had any chain-coming-off issues, so that probably was just due to the mechanic not tuning it up. But the front index shifter definitely isn't the greatest... However I usually don't use the largest chainring so I tune it for the smaller two rings and just let it rub a tad on the rare occasions I'm in the largest ring.
And I don't think the cypress is significantly lighter than the coda... Mine certainly isn't any more

The thing I liked about the cypress was that it rode so much softer. However now I've replaced the seat and seat post and the front fork has play in it, so I'm not exactly happy with that choice

You can try removing your seat post and looking at the bottom. The suspension seat posts usually have some sort of preload adjustment down there. However given that you're in the same price range as the cypress, I'd imagine your suspension seat post isn't going to be a whole lot better... which means you should toss it in favor of a sprung saddle (like the Brooks B72). When I put that seat on there I had to check if my tires were flat, that's how much better it was than the suspension seat post.
My original seat post just wore out, it got sloppy (like 1/4 inch front-rear play). When I took it apart I discovered that it's just a piece of polyurethane (or some similar material) being compressed by your weight. Which also explains why the ride changes so much when it gets cold out

BTW I'm curious when you say your "old bike" are you talking about the electric one? Is the coda a replacement for that one?
