As I turned 82, several years ago, I began thinking of a more comfortable bicycle to ride. Since I wasn't ready to quit bicycling I set out to convert my old aluminum-frame Specialized bicycle into a front wheel drive recumbent (aka bent). There expensive commercially available bents and conversion kits that offer similar configurations but I really wanted to build my own.  Just to add a little challenge to the effort three goals had to be met: all fabrication done without welding, total cost less than $100, and overall weight within 35 lbs. With a little ingenuity, I met the first two goals, however the overall weight is approximately 38 lbs. I’d like to share my solutions to the problems I encountered that resulted in a rather simple functional design.  Over time I was able to make adjustments to the design geometry to help improve riding characteristics to my liking. In the attached clip I am riding an earlier iteration of design with a straight handle bar and a stiffer back rest.

Step 1: The Steering Column and Handle Bars

1) Used MTB - aluminum frame, suspension fork, wheels
2) Road bike frame – sacrificed frame: chain stay and bottom bracket assembly, drivetrain
3) Razor scooter – sacrificed aluminum tubes, steering column
4) Aluminum walker
5) Miscellaneous bike parts, metal brackets, pvc pipe cut-offs, sturdy mesh, nuts and bolts.
<p>why a specialized? :.(</p>
<p>cool still but a specialized i have 4 whole bikes i woulda traded for it lol</p>
<p>I really like the idea of a 'No Weld' modification, anyone with minimal skill and tools could build this. </p>
<p>How easy is it to pedal and keep in straight line?</p>
amaximow excellent job. I am likewise of the older level of bicyclists and am in the process of designing a fwd recumbent bike. The Cruzbike kit that is sold is a lot more expensive so I like your approach. I am a Missourian temporary displaced to California. Can I see your bike up close sometime depending on distances. <br> <br>gardenjohn
this is a very cool bike. My attempt at a no-weld recumbent wasn't nearly as successful.
Good job! But please say how you fabricated the brackets to secure the rear wheel to the front forks. Are there any similar brackets available ready-made? Thanks.
Looks so comfy! <br> <br>5 Star, vote-worthy excellence!!!

Thank you all. Your kind comments made my effort especially rewarding for me.
Excellent job. Long may you ride it.
Brilliant! I'm totally sharing.
Great Job! I love that you made this affordable, relatively light and didn't require welding.<br> <br> I sincerely hope you have submitted this to the <a href="https://www.instructables.com/contest/bicycle/" rel="nofollow">Bicycle Contest</a>. :-)
