The Future of Shifting - LandRider???

I just saw an infomercial on the land rider bikes which boast automatic shifting! Has anybody seen or heard of this? Anybody give em a try???

Yup. They've been around for a decade or two. I've even had the experience of working on a few. It's basically a Roadmaster class bike with a centrifugal actuated automatic shifter. Considering how well even low end index shifting bikes work, I don't understand the appeal. I guess that's why they only sell them to people who haven't had the opportunity to ride one.

I rode an autoshifter around a parking lot. Auto shifting was annoying. Never could tell the exact moment when it would make the shift. Maybe in time I'd get used to it. The rest of the bike didn't make me want to spend much time with it. Struck me as a bike designed by someone who didn't ride or like bikes very much.

Assuming the bike shifts when you want it to when you are "fresh", it won't be shifting when you want it to when you are tired.

In theory, a computerized system that takes into account speed, inclination, and cadence (and has also been programmed with the rider's preferred cadence) could do a good job of selecting the right gear at the right time.

AFAIK, no systems do this.

It won't get beyond theory because most of us want to decide when to shift.
You'd have to pay me a lot to ride one.

Then you could put electronic sensors in your helmet to pick up your brain waves. As soon as you'd think "Shift." Bang! It'd be done.

This is what it'll take for me to invest. I tend to think a lot of shifty thoughts. System might burst into flames under me.

the Nuvinci CVR hub is more realistic, you decide the gear ratio, turning the grip
it is all the ratios, within its range,
between max (overdrive) and min (reduction).

not Quite automatic.. you do have to twist the grip to make it adjust.

Put it this way- the technology has been out long enough that others could have easily modified and applied to their own models without risking patent lawsuits.

Sounds like that is already being worked on...

I don't see how this would be helpful for me as I am not a car. Even with cars I dislike automatic transmissions.
With a bike at times I want to mash and others spin.

Is it based on cadence? How could it know when I want to shift?

Similar things have been said about indexed shifting, electronic shifting, and having more than 6 cogs on the rear. Sooner or later, it will be foisted on the mainstream market whether "we" want it or not.

It is the "we want it" part that makes the difference. All the other things were an improvement, Indexed, STI, more gears and yes even electronic shifting, so people wanted them and were willing to pay to get them. They existed alongside the other choices consumer could make and they made them and dropped the market for 5 and 6 speed freewheels, friction shifters and lugged steel frames. The autoshifters and even shaft drive bikes have been around and so far have not gained the "I want one" factor from the public. It could be the weight and it could be because they don't work all that well but they aren't likely to be foisted on anyone in the real near future.

It's a purely mechanical system. It's based on rear wheel rotation speed. It doesn't care whether or not you want it to shift.

Again, once the technology matures, people will eventually want it. Indexed and electronic shifting were laughed at for decades when early versions failed to catch on.

Don't get me wrong, I enjoy shifting my bike manually, but I (and you) don't speak for the entirety of the bike market.

Trust me -- the Landrider system is not one of those things. It's been around at least 25 years; and if it hasn't caught on yet, it never will.

FFS, re-read my posts. I'm not talking about the idiotic system in the OP.

The tech exists. Nothing a ANT+ powermeter, a garmin and an electronic shift system couldn't do. Getting the software written and the systems hacked (and connected to each other) would be a bear though.

I think it would be sweet, and I'm sure you could lure dentists like whoa. Set gear selections for different ride types- recovery, spirited and HOLYWOWMYLEGS or something like with power output being the difference while the system anticipates and shifts for the changing topography.

Landrider is for the retiree golf course community that thinks shifting is too complicated. When the brainwave activated shifter is ready, I'll try that.

Some years ago I read some posts from a (German?) fellow who was working on a CVT rear hub. His vision was to maintain an even input effort but to provide a handlebar control so you could sprint or stand on the pedals up going uphills. It's been several years and I haven't heard anything from him recently.

I'm thinking that a brainwave activated system might not work for that particular groupset.
