If you're 5'10", neither bike is going to fit you. The Trek is likely too big, and the Lotus is definitely too small...
You should be looking for bikes in the 56-58 cm range, in all likelihood. Fit is very subjective, but most people would probably recommend against either of those.
Search the threads here; plenty of information about proper fit.
Good luck!
