Hey  guys.    I just  sold my Rad Mini as I want a Radrunner and at the time of me purchasing, the Radrunner was backordered.  So now I am in the market for one.   I like the Radrunner but wonder if the Plus would be better for the gears.    I hear that with only one gear  one can get to peddling too fast at times.  And it would be nice to have gears going downhill so one can keep peddling at  a stiffer gear.  Any thoughts?
