Bacchetta Giro Dual 20    
15 February 2019
Many years ago Mike Kring gave me a Bacchetta Giro frame, front fork and seat. The frame needed some work. This year I decided to fix the frame and build up the bike using as many parts bin parts as possible. I decided to use 20 inch wheels and added a disk brake to the front fork. Here's the bike build blog

Barracuda Racing Trike 1.0    
25 May 2018
Over the past two years I had been considering building a trike. A carbon fiber racing trike was designed. I decided to build a mostly steel version first using existing parts to get the geometry and steering right before committing it to carbon fiber. 
The trike is now built but will need a summer of testing to see what needs to be tweaked.  Here's the build blog. These two trike pages also explain the whys and hows of trike building.

Charles Brown Recumbent Design    
3 December 2015
 

Charles Brown has created four great documents detailing many of the fundamentals and esoterica of recumbent vehicle design. 

  • Bicycle frame design explores different types of recumbent bikes and some good criteria to consider when you are designing a frame.
  • Steering and ride details what makes a recumbent bike handle well.
  • Air drag formula provides methods to determine and reduce the air drag of unfaired recumbent vehicles.
  • Putting It All Together takes the concepts discussed in the previous articles and summarizes them
Wide Eyez Bike Helmet Shield Review    
23 November 2015
The Wide Eyez bike helmet shield is an Acrylic plastic lens that attaches to your helmet. It comes in 3 colors, clear, bronze, and dark grey. Graham Hill of Wide Eyez says that the bronze and dark grey shields have a 98-100% UV rating, so they could completely replace sunglasses. It has a nice system to allow it to be flipped up or down and detents make it stay in either position. Read more...
