@ the ripe young age of 9 years I broke an arm while racing on a bicycle up hill when the handle bars came off, I can think of a few reasons why not to do this

What is achieved by doing that ? -------------------

Reverse steering as a result, turn left to turn right.

A stupid idea besides adding unnecessary weight.

Not long ago, I saw a video where this fellow made a reverse steering bicycle to demonstrate human learning or adaptation - or some such experiment.

Other than, perhaps, the brainchild of someone with a devilish sense of humor and some time on their hands, I can only think the 'utility' of such a bike would be to deter theft... okay, if I were to make one, its REAL purpose would be to video would-be bike thieves via hidden camera!

It's for the dyslectic rider.

You can accomplish a similar effect with a lot less work by installing the handlebar head turned 180 degrees. Try it but make sure your kid has a helmet, knee and elbow pads!!!! It makes the bike very difficult to ride.

About the only way reversing the stem riser changes anything on the handling of a bicycle is ,by doing so, places the bars some distance either away from or closer to the rider

Frank,

You are assuming that only the stem riser was rotated. What if the effect was achieved by simply rotating the whole fork and stem. Then you change the trail drastically and so it would be very different to ride.

Try it Frank, see what happens

If you reverse the forks as well then you change the steering inclination angle and yes the handling is much different but the steering would still remain left goes left and right goes right.

I have my first bicycle had the bars mounted with the riser nut away from me with the bars closer, and as I grew I turned the riser to have the bars further away.
my wife and I once bought a pair to 15 speed bikes she has shorter arms than I so we turned the riser so the bars would be closer to her while mine was facing to allow the bars to be that few inches further

When talking about steering inclinations angles and rake of the stem on radically chopped motorcycles or stock racing bikes you do slightly turn to the right to go left but this is because you are leaning into the turns and by leaning the bike you change the angle of approach more than you want the tracking of the wheel to follow the path of the turn. low speed turns you turn left to go left but the faster you are going the more you lean the bike the less you turn the bars or even turn the slightly in the opposite direction

Just beause you can build it - does NOT mean you should.

When I was a kid there was a place at the local beach amusement park that had several of these reverse steering bikes. You would pay to try to ride it around a short curvy loop track. If you could make it around without putting your feet down you won a teddy bear or something. The guy manning the game was always zipping around the track making it look easy. I never saw anyone try it succeed. One of those carnival games that can be made to look easy but really is not.
