2016-02-25 (Th) Simple Recumbent Bike Without Welding

Wide braces were purchased to accept a 3/8” hole for the hanger and the 1/4” hole for the beam clamp. Slender braces would have been weakened too much by drilling a 3/8” hole.

There was ample metal after drilling into the brace. It got hot when the bit dulled but the hole was fine and the back side, which had remnants of the drilling, was ground down to a flush surface.

Beam clamps would not align with the clamp then single-hole cable clamps were used. They were able to attach but they were not sturdy. These clamps were easy to attach but they will not work because they are too flimsy.

When the upper frame was attached it was easy to see that the pedals could easily hit the wheel below. This will have to be raised several inches so feet and pants aren’t touching the wheel while turning. The upper frame bars, which previously made it look like a unicorn, were trimmed off to make transportation easier.

Pedal hitting tire and trimmed bars

To do:
  • Permanently attach upper frame
  • Remove cranks from lower bike
  • Run chain between cranks and wheel
  • Construct idler sprocket
  • Test
  • Strip pink paint
  • Repaint
