On the sides of the back wheel, attached to a back rack, are two robotic "spider legs".

When the bike tilts too much, one of the legs extends out and steps down, saving you from losing your balance.

If you press the brakes {strikeout: breaks, thank:[Voice]}, it stops you as well, if not, it just brings you back to balance, while stepping forward at the speed of the ride.

The leg has a floor contact sensor and a pair of cameras for robotic 3D sight.

This will allow my 87-year-old father to safely ride has bicycle again.

The same legs, this time connected to the body could work as a fall breaker for walking. Falling is a famous problem with the elderly.

Body mounted airbags would work better than spider legs

You need the legs to deploy instantly the danger is detected. Electrically powered sounds to slow and laggy. What we need is a mercury tilt switch wired to a belt-fed cartridge powered deployer.

If you're using gas-powered deployment you may as well make it simpler and use a pair of rockets, one on each side. That will also make it much more controllable, since you generally know how much thrust you have but you have no idea how far a leg has to extend before it will support you.

A1 wow!! [+ on your AiroNoodle]. Question, you never have fishbones or do you simply agree with everyone that it was probably a bad idea and erase it?

Voice thanks. Corrected. [+ on your A book I can read that tells me what to do]. Question, why the fishbones?

Please don't bun my ideas for any reason except that you like the idea.
