Hi,
I use my trekking to go at work every day, about 20km per day, no hills, no mountains.
I usually use "heavy" gears because I like going fast and the street is flat, so everything is fine.

I really like how singlespeed bikes look but I'm wondering if the gear is to soft to go really fast...and unfortunately I have no way to test a singlespeed here

what do you think?

thanks
