Hello. I just received my Schwinn loop from amazon about two days ago. I like it so far. I am replacing the seat with a "Planet Bike Men's A.R.S. Anatomic Relief Bicycle Saddle" in hopes that will make for a more comfortable ride. Other than that I was thinking of either changing the crankset over to a 52 tooth crankset such as "New Bicycle Fixie Fixed Gear Bike Crankset Cranks 52T Anodized Purple" off ebay. According to this guy I'd have to buy a new chain and do some modifications:

Now I was wondering if installing a front deraileur on this bike would be possible at all.
Parts:
-Origin8 Alloy Cable Stop - I'm not sure where this could even be mounted to (maybe the seat post part of the frame) or is it even necessary since the barrel bolt is attached to the shifter
-Vuelta Corsa Pro Crankset 52t/42t/30t crankset
-Shimano FD-TX50 Tourney Front Derailleur (34.9-28.6-mm 3x6/7 Speed Low-Clamp) - mounted to the seat post part of the frame
-Shimano Road Shift Cable and Housing Set (Black) - to cover the cables
-Shimano RevoShift Friction 3 Speed Left Twist Shifter - mounted in the normal place

Any thoughts would be much appreciated. I understand that this is probably not possible and I might just go for the 52t fixie because I almost ride in the 6th or 7th gear constantly so if i put the 52t on i feel i'd be somewhere in the middle with the ability to shift up and down to where i need it to. The added threee gears would just add a further amount of customization. Another question what if I use the 3 chainring crankshaft as a manual fixie that I would just use my fingers to move the chain?
Also would I need a longer chain if I did either of these modifications. Thanks in advance
