42:13 is a freaking steep gearing for any day to day riding unless you live in a place that is perfectly flat and where the wind never blows.

I run a 52:18 on my road bike and folks here think that's pretty steep (77 gi) since we do have hills and the wind never stops blowing.

My fixed folder freaks people out as it runs a 52:14 and although the gearing looks massive, with the 20 inch wheels it only works out to 69 gear inches and there is a 16 tooth cog on the flip side for those really windy days.
