I like #2 quite a bit; the motion of the passing cars combined with the feet up on the handlebars makes for an interesting combination! The composition doesn't quite do it for me, though.
Interesting picture, well done technically, good conversion but badly framed.
Why the space behind the pedi-cab?
If you leave space, viewers will assume it has a purpose and look there.
Direct the eye to where you want it to go.
Now the pedi-cab sits in an important spot, the legs point to the cars whizzing by and there is no reason to look behind the pedi-cab
