Design Philosophy

When I started this project, my initial goal was merely to create a penny farthing bicycle.  As I let that concept marinate for a while, the goal was refined to include two items:

  1. Use the big wheel / small wheel architecture
  2. Utilize as many modern materials and components as possible
That led to some early decisions such as using aluminum rims, disc brakes, an aluminum frame, and a freehub front rim.  I am already regretting some of these choices.  For example, the rims were difficult to find (no, I didn't want to fabricate my own).  I did eventually find rims for sale on a UK website for unicycles (http://www.unicycle.uk.com/penny-farthing/rims.html).  Everything seemed fine until DHL delivered my overseas package.  The unsupported aluminum ring was overloaded in transit and arrived with a nasty crack starting in a spoke hole.

After spending over $200 on the rim and $70 on shipping, I was just as crushed as the rim.  Roger from www.unicycle.uk.com came to the rescue!  He processed a claim with DHL, found a better way to package the rim, and sent a replacement for FREE.  Great customer service.  The new rim arrived a few days ago.

Rim #2 with a tyre
 To aid in the packaging, I had them add two solid rubber tyres (these are from the UK) to the shipment and wrap them around the rim.  I still haven't figured out how to permanently apply these tyres on the completed wheel.

What can I buy with a penny and a farthing?

I'm starting this blog to document my project to design and build a "new" penny farthing bicycle.  There are multiple sources online that document why these high-wheel bikes from the late 1800's were called penny farthings, but a picture says it best.

Farthing = small wheel, Penny = large wheel

Since my native currency is not based on the Pound Sterling, this project is being christened The 35 Cent Bike.  Not terribly creative, but the imagery works the same.

So, here we go with the project...
