Another large front wheel design I've done (and plans are there) is at http://www.modularbikes.com.au/zeica/ For me the small wheel at the back allows for a very simple, large carrying capacity, highly visible tail box which has great advantages for a practical vehicle used for shopping and general transport. My latest bike can even carry a carton of beer, and I've done several 150k plus day rides on it. But not carrying beer!

This is a bit offbeat, but probably interesting to lovers of workbikes. Being a tourist town, Austin has a lot of pedicabs in it. I like pedicabs, as I like it when people use bikes for practical purposes, and I like big workbikes/trikes in general. Like many, I'm leery of "pedicabs" which are large trailers (always without their own brakes) whose gross, loaded weight far exceeds that of the mountain bike and rider towing it by the seatpost. Known trailer crashes include jackknifing when the bike brakes during a turn, seatpost failure, or falls when the rider is unable to climb with the load. A trailer costs about 1/10 of what a new, purpose-built trike does but it can be leased out at the same rate as a trike pedicab, so they are flooding the local market, hurting operators (not so much owners/lessors). Most cities with pedicabs don't allow trailer pedicabs, but Austin hasn't set such rules yet. The city is in the process of revising all its pedicab laws in respo</pre> Easy Street 2011-11-03T02:22:52 http://comments.gmane.org/gmane.culture.transportation.humanpowered.general/5470 <pre>Parlee Cycles in Massachusetts is using a smart-phone app such that "a cyclist can change gears with a thought.

I could hear it clicking. Being a good, conscientious, rider, I checked the left wheel as well. Yoikes! Where are the spoke heads that are supposed to be looking at me on the trailing spokes, inside? Gone, gone, gone. A reminder: don't be like me. Safety check your wheels more often instead of less often. If I had been what I was, I would have kept my wheels tight and those spokes probably would not have parted ways with their head buttons in the first place. Edde: Who da fool?

Well I just replaced the Wippermann Connex 10s1 10- speed stainless steel chain on my Bacchetta Aero after 23,762 kilometres. One of my chain wear measurement tools indicated it is time to replace it while another tool indicated it was still in fair condition, not to the replace mark yet. The reason why I replaced it is because the chain has been getting noisier lately. Based on how long this chain has lasted, I replaced it with another Wippermann 10s1 chain. I am using Wippermann 10-speed chains on 2 of my other bikes, a SRAM 10-speed chain on one bike and KMC 10-speed chains on 2 other bikes but as I divide my riding time between many bikes, I have yet to wear one of these out. The only maintenance I do on my chains is applying ProLink when the chain starts to get noisy and wiping off the excess. ------------------------------------------------------------- Zach Kaplan Cycles 510-522-BENT (2368) zach&lt; at &gt;za</pre> Zach Kaplan 2011-07-27T17:02:03 http://comments.gmane.org/gmane.culture.transportation.humanpowered.general/5456 <pre>"Now I just need a bike helmet that matches!

I've been using 20 x 1.35 and 26 x 1.35 tires on my Vision R55. I've generally used Vredestein S-licks (now discontinued) or Schwalbe Kojaks (which develop a lot of nicks and cracks). To deal with frequent punctures, I tried a set of Schwalbe Marathon Plus(es). Very heavy -- around 775 gr. But I did not get any flats at all. However, my legs felt like concrete. My speed went down about 15%. Riding up any rise became a chore. I thought it was my age, but I swapped the Kojaks back, with extra rubber tubing in the vital spots, and my speed has gone way up along with my enjoyment. I'm thinking of getting a pair of Primo Comets with a Kevlar belt under the tread. Though they do make a 20 x 1.35, they don't make a 26 x 1.35. But they do make both a 20 x 1.50 and a 26 x 1.50. They pretty much slicks, and they seem to be somewhat puncture resistant. So, does anyone have any experience with these tires? Would it be okay to mix and match -- a 20 x 1.35 front and a 26 x 1.50 rear -- or would</pre> Lloyd Abrams 2011-07-15T02:19:06 http://comments.gmane.org/gmane.culture.transportation.humanpowered.general/5438 <pre>The way I read it, this is a Schlumph product.
