A 27" gear from direct drive is utterly impractical. Direct drive is only 8mph at 100rpm. You go at a nice cruising/commuting speed of 20mph you'd need to spin

A 27" gear from direct drive is utterly impractical. Direct drive is only 8mph at 100rpm. You go at a nice cruising/commuting speed of 20mph you'd need to spin out 250rpm. I can only maintain 200rpm for short bursts!
It needs something akin to a the Schlumpf "mountain drive" cranks (to lengthen the gears rather than shorten them) to give a gear up in to at leas the 60"-70" gear inches range that's more suitable for road use.
