Stainless Steel Touring Bike

This bike has gotten a lot of attention so far in its short life. People seem to like shiny things, and this one does indeed shine. Beyond being blindingly bright, there are so many details that I figured I ought to lay it out for those who might be interested. The bike is mostly finished. There are a couple more bags that need to be made, and a decaleur that will mount off the stem -- in this sense it is still a work in progress. So, here's the low-down:Stainless Steel Touring

Spork Head Tube BadgeThe frame and fork are made from KVA stainless steel. The split-plate fork crown is made from laser cut stainless.  The racks and stem are made from chromoly steel, and were polished and chromed.

The bike has 26" wheels (international standard -- this is a touring bike, after all), disc brakes, a connectorless front generator hub made by Schmidt. That means that there is no plug to worry about when changing a flat tire. The wire runs from the inner face of the dropout directly into the fork leg. The front and rear lights are powered off the hub, and the wiring is all internal.Breakaway Binder

The frame is a breakaway style, with a coupler on the down tube, and a breakaway point on the seat tube. The seat post is integral to the structure of this system, which is brilliant and simple (No, I didn't invent this. Neither did Tom Ritchey -- it came from way further back than even his design). The seat stays come in below the seat tube breaking point, and the rear rack stays attach higher up on the seat tube, where seat stays would normally be. This gives the bike the appearance of having a traditional rear triangle, and serves to support the rear rack. 

Front Rack & LightThe front rack has an upper deck that can be used intependantly of the low riders, which are detachable. The rack supports the fender and the front light. The rear rack has an integrated u-lock holder. Notice the leather sleeve on the lock shackle. This was made by Dirt Jr., right here in Portland. I plan to put these up for sale on my website soon. They look so much nicer than what comes with the lock. We're working on a vegan option as well. 

Rear Rack & Lock HolderThe frame uses traditional tubing dimensions (1" top tube; 1 1/8" down & seat tubes), and has a straight truss, or second, top tube. This supports the head tube and seat tube, stabilizing the ride for weight bearing, particularly when the bike is fully loaded with bags. The space between the two top tubes was an ideal place to add storage, and the frame bag was custom made by Black Star Bags here in Portland. There's enough capacity in this bag to carry a couple of tubes, maybe even a folding tire, tire levers, patches, a multi-tool, energy bars, phone, etc. 

Stainless LogoThe down tube logo is also stainless steel, laser cut and brazed on. It took three of us to keep it set while brazing. Next time, I need to video record the process. I left the panel around the logo exactly as it looks right after brazing, without polish. That gives it the burnt, dirty look, which really stands out nicely.

There is a polished titanium spork head tube badge that is removable, and fully functional. People who ride bikes have to eat, right?Stainless Steel Touring

Part of the reason I built this bike was because I hadn't yet seen a really utilitarian bicycle made from stainless steel. Stainless is expensive, and the amount of time and labor required to bring it to a mirror finish was ridiculous, but the final product is so striking that I believe it was worth it. I hope you agree. I would like to see the same style bicycle, or something worthy of commuting, made from stainless steel and with a brushed finish. Everything Shiny!

Polished StemAnother reason I built this bike was because I was invited by the Portland Art Museum to display a couple of bicycles along with the Cyclepedia exhibit this past summer, 2013. It was an honor to be invited, and I wanted to make something that I believed was worthy of being shown in such a prestigeous museum.

Here above is the photo series from my flickr site. There are a few repeats, but I chose to use them all, because each of them looks so good. Photo credit goes to Anthony Bareno. He took all these in the studio at Velo Cult. He said it was the most difficult bike he's ever shot. Too many reflections. If only there were some way to photograph this bike in the dark! Please check back in the future to get a full ride report.

NAHBS 2012 Preview

I've been pretty quiet over the past several weeks. It's been a busy time trying to get everything together for this years' North American Handmade Bike Show. The show is scheduled to take place in Sacramento, California from the 2nd through the 4th of March. If you can make it, definitely go.  

Here are some random photos of projects I've been working on for the show. I'll try and post more pictures soon. Enjoy!

Off Road Touring Bike

Ride Review

The BeastIn Portland, Oregon, we're pretty lucky to have Forest Park, one of the largest urban parks and nature reserves in the country. The main through-way in the park is Leif Erikson Rd., which is a mostly unpaved fire road that runs nearly 12 miles from one end of the park to the other. Forest park is a great place to walk or ride, and it's only about 10 minutes (by bike) from downtown. 

Yesterday I rode through the park. The sun was shining and by mid afternoon it was nearly up to 70 degrees. I rode the new 29er touring bike totally unloaded to see how it handled, changing the tires from 47c semi-slick road tires to WTB Exiwolf 29” x 2.55 – big fat knobby off road tires. This is the same bike I picked up in Eugene and rode back to Portland a couple of weeks ago. It's a stable bike, but I wanted to see how it handles at speed over bumpy terrain. 

This bike was built primarily as a touring bike, and has the clearance for fat tires and fenders. I haven’t reviewed this bike yet because I wanted to spend some time in the saddle in various conditions and see how I liked it. For the trip back up from Eugene it was great. Very stable with weight, sure handling, comfortable, a wide gear range. Even with about 15 pounds of gear on the front I was able to ride no-hands without a problem. 

Park Entrance from Germantown Rd.

Going through the park yesterday I was again impressed with the stability and handling. The bike has detachable low rider mounts and a fairly sizeable upper deck on the front rack, which means it can hold a lot of gear. Even unloaded the bike steered easily, and flying down a rocky, gravelly section of Lief Erikson I sat back and took my hands off the bars and the bike held its line easily. Stability, no hands, with or without weight on the front – I like it. 

I didn’t remove any of the racks, and carried along my u-lock in the integrated lock holder on the rear. The bike also has large stainless fenders, mud flaps and a kickstand – all these things add up, and make the bike heavier than one I would usually ride through the park. I would like to strip the bike down to the bare essentials at some point and try it out. But, even with all the extras on the bike I was very impressed at how quiet it was – no rattles, squeaks or knocking. Even the lock shackle is wedged in so it can't rattle. The only thing I noticed was that in especially bumpy places the lower part of the front fender would shake back and forth enough to hit the knobs on the tires -- not a big deal, and to be expected riding off road with fenders.  

Knobby Tire TouringAnother trip I want to take is with the bike fully loaded on the same trail, just for a comparison – fully loaded front and rear panniers and a dry-sack on the upper deck of the front rack. I want to pack it as if I were going for a long trip off road. It will be slower going, obviously, but I’m very curious to know how it feels. I’m fairly certain that it’s going to do just fine.

You know what would be even better, would be to pack it as if I were going on a long bike trip, and then go on a long bike trip. We’ll see what this summer brings…

Off Road Touring Mixte

“What is this thing?!” This past October at the Oregon Bicycle Builders’ Show, Jonathan Maus of bikeportland.org stopped by the booth and was looking at this crazy bike of mine. I tried to sum it up as succinctly as possible: “It’s a mixte off road touring 29er commuter monster truck thing, with a flask cage.” Something like that. The bike was hanging on a stand at the back of my booth. I’d been riding it for a couple of months without paint, and it had a nice patina of rust going. When Jonathan was done taking in all that information the only question he could think to ask was, “Why?” The only proper answer to that is, “Because I can.”

Joseph Touring

This bike was built with the thought in mind that here in the northwestern US, there are more miles of logging roads and forest service roads than there are paved roads. So why not build a camping bike that can truly endure the long out-back haul. This bike was built with an up-right touring geometry, and adds some elements of the 29er mtb. Expect to see more of this style of bike in the future -- it's a great multi-purpose bike that can really go the distance.
