Interesting concept, but it would have to extend further out to be useful at speed. Come to think of it, what about just lights?
I’ve admired Fastboy Cycles for a while now, as images of his latest creations regularly grace my tumblr feed. The bicycles crafted by Ezra Caldwell are truly works of art. His story about building bikes is inspiring, but what he is going through makes it all that much more amazing.
For Bike-to-Work Day, here’s a little part of my daily ride. It’s a short boring video where absolutely nothing happens. This is my favorite part of my journey to work every weekday, between the city and the campus. It is called the “Chemin d’Enfer” [Path of Hell] but I find it quite soothing compared to the rest of the trip. I have come to think of it as the “Cathedral” with its arching oak branches towering over the foot path.
If I didn’t bike to work, I wouldn’t be able to enjoy this little corner of the world, seeing the change of the seasons, and listen to the birds.
The Kona Unit is a big bucket of fun. However, I don’t have enough experience with other mountain bikes to make a proper comparison. My other one is a ‘98 Cannondale F900 which is outdated compared with today’s bikes.
Participating in weekend randonnees, I can say there is a big difference in riding style with all the multi geared full suspension bikes out there. Despite the single gear, I usually rocket by other bikes on climbs since it is so light. But climbing on a singlespeed takes anticipation, you have to build and maintain momentum to keep going. On steep sections, if you stop, you have to get off. This is often caused by traffic in granny gears blocking the trail.
My Unit is the 2010 version which has a pretty steep head angle (73˚) which makes it a little more reactive, but also a bit more scary going down hills. Kona has changed the geometry since, and is on par with other brands.
The Unit was also pretty cheap to buy, but I’ve made improvements. I replaced the heavy Cro-Mo fork with a nice carbon Niner fork, and replaced the heavy stock wheels with some No Tubes ZTR Crest rims running tubeless and Hope hubs which are as loud as a plague of cicadas, but has quick engagement.
Finally, having no suspension means that I can’t bomb the hills, but I enjoy the challenge of carefully picking out the right line, and keeping my arms supple at the same time.
Thanks for the question!

Ready. BTWD.
Ah my old home town, I wish I could be there. Make a day of it my peeps.

Too nice to let go unnoticed. I find most wood applications in bikes to be over the top and awkward. This is a light application which really makes a cohesive design. The single-speed belt drive is a nice touch too. Too bad there don’t seem to be any holes for fitting fenders.
Treffendel Randonnee : a pedal strike to the shins, once over the handle bars, and a flat tire. It was an excellent day. Good weather and a really challenging course. Only did 35 km.
