I am looking at the Mercier Kilo s3x and wondering if it would be worth getting the 3-speed if I switch out the cog for a freewheel. Does anyone have any experience with this bike or 3-speed internal hubs?

I would be using the bike for commuting and I'm not sure if the 3-speed makes that much of a difference. Input is appreciated! Thanks all!
