Here's the original plan, you can see the handlebar with built in brake levers resembles the folding handlebars.

Here is the result at the end of the day.

Hi
For a long time I've been riding bikes which have the brakes reversed - this is possible because the handlebars don't bear any of my body weight. When I slow down I can allow the natural decelleration body motion to press in the brakes, but I still have the normal hand-squeeze braking method. For a long time I've been thinking about using the decelleration only, like trailer brakes, but have only started building something in the last few days, after gathering a dead kid's scooter and stealing or swapping out bits from other bikes.
I was inspired by seeing a few bikes with Shimano DI2 electronic shifters on them at a recent bike show. Surely there are ways of streamlining a bike's controls that don't involve wifi, batteries and software! A recent Age article echoes these thoughts, "It was common for cars, fridges, and even coffee machines to have embedded software".
Its all going well and I will report further.

June 7, 2021, bit of progress today. I made some handlebar halves from a straight aluminium bar and gathered a few other bits, gearchanger, bar extenders and a bell. If the brakes don't work I will at least be able to warn people to PANIC and get out of the way. |

Most of it already made. Top is the folding bar that is being replaced.

June 8, 2021, Good progress above as shown. I made the handlebars with some holes drilled so they can double as brake levers. Still a couple of days work before I can test the idea. The story continues in this post.
