Auto Trans!?

I was at Performance Bicycle and they had bikes with 3 speed autos, a guy there let me ride one around the store, it was weird, I've never seen something like that.
Personally, I want a bike that has a 4 speed on the frame in the H pattern with a clutch though

Try an interweb search for gearbox bikes there's an older model that changes gears on back pedalling. It had either a 3 or 4 ratio gearbox.

These days there are quite a few gearbox bikes out there, some good (rohloff, nicolai bikes, schlumpf, etc.) and some bad.

There's also the G-Boxx initiative trying to get bikes away from crap derailleur based systems.

Don't run red lights, wear a helmet, use hand signals, get some cycle lights(front and rear) and, FFS, don't run red lights!

The auto-shifting bikes are interesting; not to me but I suspect they'll sell a few. Actually, it dawned on me the other day that an auto-shifting bike might serve people who are developmental delayed, or have had brain injury--not just people "who can't figure out how to shift". There are probably some people out there who ride many miles, and would be well served by a bike that knows when to shift for them.

I'm looking forward to the day constant velocity transmissions are small and light enough to be used with bicycles. What would be even better would be some sort of system to change the threshold so you could pedal at ~90rpm when seated and ~60rpm when standing.

You'd never have to do anything else, no matter what the terrain, as the continuous gear range and the constant velocity transmission would always keep you in the right gear at that cadence.

N.B. I DON'T mean infinitely/continuously variable transmission (e.g., the nuvinci gearbox) although a constant velocity transmission may contain one.
