BERKELEY, Calif. — ILE is big in Japan. The California bag company has found a market with the Japanese bike website Blue Lug, and the collaboration keeps pushing ILE into new bags, materials, hardware and color choices.

Eric Fischer, 26, launched ILE (short for “Inside Line Equipment”) out of his apartment four short years ago. He was racing bikes, buying fabric and making bags one at a time for himself, his friends and friends of friends.

“I always liked making things, but building buildings didn’t seem scalable,” Fischer told Cult of Mac. “Making bags seemed more like a painting rather than building a house.”

SAN FRANCISCO — Twenty-five years ago, a bike messenger sat in his garage and used an old-school Singer sewing machine to stitch his mark on the world.

That bike messenger was Rob Honeycutt, and the bags he made in 1989 were called Scumbags. They were designed for use by the city’s notorious two-wheeled delivery riders, whose fashion sense tended toward crude cutoffs, T-shirts and hoodies.

A year later, Honeycutt changed his operation’s name to Timbuk2, and the company’s been crafting an increasingly ambitious line of bags ever since, expanding far beyond the world of tattooed dudes on fixies.

“Timbuk2 wasn’t going to the office 25 years ago,” CEO Patti Cazzato told Cult of Mac during a recent tour of the company’s Mission district factory, where all of Timbuk2’s custom bags are made.

No one but actual, honest-to-God bicycle messengers had the authority to wield a Timbuk2 messenger bag. If you were an iron-assed hard case living life on a bike, you’d probably earned the right; though you might still have found yourself the target of diluted messenger disgust.

That was the pervading vibe 15 years ago when I bought my first Timbuk2 bag, a Bolo (back then, each size had a name; the Bolo was the large version). Make no mistake, these were Messenger Bags: simple, voluminous, virtually indestructible black holes, able to swallow an inordinate amount of awkwardly dimensioned deliverables, specially stabilized for use on the bike exclusively. The only grudging nods to civility were a couple of pockets sown onto the outside of the bag and an optional padded shoulder strap.

And apart from a few minor changes, it’s stayed that way. Like the coelacanth, the Classic Messenger has remained a living fossil, unchanged, while other Timbuk2 species have evolved and developed around it. Until now.

The Mission Cycling Wallet is a lot like those iPhone card wallets you see all the time, only this one zips your iPhone safely inside, and lets it face out through a see-through screen so you can read it and use it without taking it out or opening the case.

You can even use it in the pouring rain.

Nothing screams “summer!” like a bag full of beer and ice. The messenger-bag gurus at Timbuk2 know this, and have re-clad and re-released their stealthy party-in-a-bag bag, the Dolores Chiller Messenger — this time in Pilsner Urquell’s signature green and white colors.

You may be asking “can’t I just dump all the stuff out of my own messenger bag and fill it with beer and ice?” Why no, you can’t. Your bag’s interior isn’t insulated; and more importantly, your bag doesn’t come with a handy bottle opener.

If it isn’t already obvious: I’m a huge bike nut. I’ve sold bikes, fixed them, raced on them and even slept on one once (hey, cycling is tiring). So I get pretty excited when fellow bike nuts make something ingenious that’ll let my bike haul my Apple gear. Case in point: Timbuk2’s new Basket Case duffel and their Cog Pannier.

If you’re an iDevice power-user and need a classically robust bag to haul all your junk, take note: Timbuk2 has just released the Power Series, two alternate versions of their best-selling Commute Laptop Messenger and Q Laptop Backpack, equipped with Joey batteries and special a pass-through for the charging cable.

SAN FRANCISCO — American companies are rightly proud to show off any manufacturing facilities supporting jobs during the current recession, and San Francisco-based Timbuk2 is no exception. This week, the company known for its messenger bags showed us the hangar here in the Mission district where workers cut and sew colorful swaths of material and help contribute to the local manufacturing economy.

As a group of reporters was ushered through the trendy open-plan set-up, it made us think about what a factory tour of Apple’s manufacturing plants would be like. We’ll never know, of course. Tim Cook would never allow a tour like this one.
