Think different: forget the bike, get a chair. A big comfy one.
Build a recumbent frame to go under and ride in style!
Step 1: Chop Chop
Nibble up your leather
Step 2: Get Framed
This takes time and guesswork. Measure things like your legs, a bit of giggling.
Made up a 2" pine mock up and chopped up some junk bikes... MTB for the rear - and a kids's bike with 18" wheel for the front.
Step 3: Steel Yourself
Actually Julian did this for me. I'm a bit wooden. He copied my pine pattern behind in 2" square section steel. V solid. the clamps are trying to guess the chain runs with Juriaan Bol's chain runners (www.dutchspeedbikes.com) he does recumbent bits.
Step 4: Back Up
This has to be very strong.
Step 5: Full Frontal Nerdity
I just guessed rake angle - the human eye is a wonderful thing. In the end I can almost ride it no hands...
Step 6: Chained Up
Yep, it works. Two and half old chains....
Step 7: Screwed
Together, so I can take into two for easy transport.
Step 8: And Screwd Again
No huge precision required. It just has to work, be strong and look pretty on top.
Step 9: Three Point Linkage
So the thing doesn't wobble... and goes together / comes apart quick.
Step 10: Skid Row
Castors are a very very bad idea. But the leather takes a scraping - ask any biker. So here's a bit of scrap oak. The fuel line is a tilt device - it works to some extent but by the time I hear it I'm probably wobbling in a tight corner and in trouble enough.
Step 11: Skid Stops
Can pull them out or replace..
Step 12: Strong Stuff
The 18" was replaced by 20" front end with v-pull brakes. This improves ride height and helps pull up. You have to pay for real comfort, and this saddle is sooooooh heavy.
Step 13: This Is It
Armchair or bike - you decide.
Step 14: Does My Bum Look Big in This?
41" inches wide. For less than a Double-sprung Gel Comfort saddle.
Step 15: Armchair Cyclist
My other bike is an armchair.
