Messenger Bag vs. Back Pack

[Ana]

So I know a lot of cyclist commute with a messenger bag instead of a backpack. I've always been partial to a back pack, although I may consider switching.

What are the advantages of a messenger bag and why are they so "useful"?

They totally don't work for me. Boobs get in the way and I don't do well asymmetrically.

Backpack... or Xtracycle

I didn't like any of the cheapo messanger bag knockoffs I tried until I tried a timbuk2. It has a strap that keeps it in place. You could sew a support strap onto a regular messanger bag though, if you didn't want to spend on a timbuk2.

The timbuk2 holds a laptop and clothes, is water resistant, easy access, good pockets, strong material.

A backpack seems to ride higher on the back, which, when you're on a road bike, is kind of uncomfortable.

I prefer a messenger bag over a backpack for cycling. The m bag rides lower & is in minimum contact with you, so you don't end up with a sweaty back.

I much prefer panniers over either a backpack or messenger bag. Keeps the weight on the bike and off my back.

If you're carrying a lot of weight, the panniers are best for your bod.
But for a medium amt of weight, the backpack does keep it more balanced.

If forced to choose, a backpack not a messenger bag. I have hybrid bikes.

Small framed folks like me, just have less mass for a messenger bag to rest. I genuinely have a small back...my bra size is an example (circumference, not cup). I would be nearly embarrassed to say how narrow I am....

However I dislike anything on my back when I cycle. Pannier(s) ...the issue of aerodynamic is abit of a misnomer..when the pannier is near empty...for a good part of the ride.

As for weight balance, it's ok if balanced between 2 panniers. Add on front-loading and that's quite different.

I actually find some weight in my pannier(s) keeps me more steady on the bike, when it gets quite windy or when backdraft of transport trucks hit me. Well think about it, if a person is 100 lbs. and there is high winds...
