Would it be cool if we have automatic shifting

Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

like the automatic transmission in cars so all we need to do would be dialing in some power/cadence parameters and the thing shifts for you. of course you want to have a manual override function too in case you want to mash it...

there have been bikes with auto shifting in the past. Don't think they caught on since i haven't heard anything in many yuears.

And no it won't be fun, automatics aren't fun to drive.

I think Shimano tried something similar to that, but it doesn't work as well as expected.

Can someone back me up on this? What was that called?

automatic transmissions in cars don't have a direct mechanical connection between the engine and the drivetrain. They use a torque converter, which is just a hydraulic pump.

It would be very jarring to have a gearbox automatically shifting the gears for you without a torqueconverter type device.

Hey, remember the Autobike? Didn't catch on too well. Loved watching the infomercial when I was a kid.

Once a completely uninitiated asked, Why do u have all those gears?

Auto would be good to those types who wouldn't care a wif about the Mx and just wanna pickup a carton of milk at the store. When the auto mechanism goes clunk though, the said person may be scared out of his/her wit.

A Continously-Variable mechanism would be cool just to see how it works.

Trek Lime but don't know about the power/cadence stuff

"Lime is for everyone. Even people who donít ride bikes. Itís a fun, easy three-speed bike that shifts automatically, so all you have to do is enjoy the ride."

I had a motorcycle once (Boss Hoss) that had a single-speed tranny. If P/W is high enough, you don't need more than one gear.

I haven't driven a car with an automatic in many years, so why would I want my bike to work that way?

I agree, CVT would be the way to go - I could actually see that working pretty well if you could nail the technology right.

The McMerc SLR only comes in automatic, given the massive torque of the beast I would say it's a *good* idea.

And I can't imagine it would not be fun to drive. I imagine it would be up there with all the rest of the fun cars until you melted the tires and burned up a tank of gas every 15 minutes.

Yeah, it costs a half million dollars. Real fun isn't cheap.

There was also another autoshift cruiser I saw on an infomercial last year - I think that's the aforementioned LandRider.
