When restoring a bicycle, my goal was to spend less money as possible, so it became upcycling, recycling, pimping and transforming with materials available.
Current saddle didn't have a vintage city bike look.
Purchasing a Brooks saddle or similar would not help my to set up my goal, so here is the project, hope this will inspire.
Step 1: Disassemble, Shape & Tape
Disassemble old saddle and shoes.
In this case the saddle has a steel frame and plastic moulded shell.
I have cut the shell in the shape I wanted and have ground the frame following the shape of the shell,
also I have removed some of the steel suspension.
The plastic shell was cut in half to get a perfect design, following the adapted frame.
Tape the 2 halves together with duct tape.
Before sewing provide rivet holes on shell and frame (see last photo premounting rivets).
Step 2: Sewing Pattern
Position the leather parts of the shoes with needles and paper tape on the plastic shell.
Use the old pattern to get a similar curve at the back.
Start sewing plastic shell and leather together by hand, handle carefully !
When sewing use appropriate needle, wire and supporting plate to apply guided and safe pressure,
Step 3: Rivets & Finishing
Mount the saddle on the frame by placing rivets and flat washers, polish the leather and ... done !
Notice : Because it was made of shoe leather, the saddle is comfortable (also due to small suspensions in the steel frame) and feels soft enough, so the seams (and rivets) are not creating problems such as blisters or damaging pants.
