Wide Rim Weight Reduction Experiment. For Acceleration Improvement. by Brian Miller, citizen scientist. CONCLUSION: Worthwhile. For the environment of paved city street riding, improved deceleration, acceleration, and steering speed are rather beneficial; lighter rim is better. ABSTRACT: An unusually wide bicycle rim is needed for a high performance urban bicycle project. To improve [more…]
This has been the best iteration of this bicycle design. I have ridden this frame a lot, mucho trial-and-error with component advances. The result became: Light, compact, and nimble, yet hard; intended for broken big city streets. Acceleration among traffic being a top priority for componentry harmony.
Check out this great old Giant Cadex 3 frame. The tubes have a variety of weave patterns. Detailed engineering for a new path; carbon fiber was very new and exotic. Then I sought and found a Specialized Future Shock FSX carbon fiber fork. This one is from 1994 with titanium hardware. It is a great [more…]
Sand Dragster bicycle – Beach Cruiser by Brian Miller A class of riding improved through rigorous testing at the beach. With some friends and people I didn’t know, I had rented a island beach house for the summer. I wanted more than just the everyday beach frolic, drugs, and sex; so I started a project. [more…]
From my experience of building a high handlebar chopper, I learned the value of giant rear tire / skinny front tire. The problem, I discovered, is that the eye perceives the skinny tire as having a smaller diameter, compared to the fat tire. Optical illusion, and not the way I want it. I could visualize [more…]

nnnnnn Hot Rod Girl A ride for New York artist Simonetta Moro She is sly with her color and camouflage. The magenta letters and pink wheels go nicely with the dark purple metallic paint. Plus the drivetrain is super hot. Those top of the line racing Dura Ace hubs are so [more…]
How to rebuild a Manitou suspension fork, replacing the elastomers with springs. The early Manitou forks are well designed, light, simple, and work well. They don’t have as much travel as offroad forks of today, but they are very good for street riding. Their springs (elastomers) often decay over time, but can be repaired. [more…]
Super Street Machine. Maybe Supabike. This one has the 52 tooth top ring. The 52t chainring gives the proper top gear speed, but doesn’t shift so well.
