IMO automatic shifting on a bike is an answer to a question they should not have been asked. Both my bike and trike have grip shift. Therefore a slight twist of the wrist will put me in any gear that I feel I need. Virtually all derailer systems are fully developed and shift quickly and quietly.

You could say the same about an automatic transmission in a car, yet they're still massively popular in the US.

Sure, bikes are a bit more of a niche market, not really having a lot of people interested in them that don't know how to shift, but maybe shifting is the activation barrier that most non-bike people can't overcome?

But I think the Nuvi constant gearing thing already solved that honestly.

Personally, I'd love to have an automatic shifting bike as long as I could play with the algorithm, simply for scientific and programming fun.

Automatics in cars is a far different situation. I still remember driving in San Francisco on a steep hill and when the light turned green the stick shift artist let his car drift back into mine, trying to get it going.

That's true, I'm already looking into a patent, I think it's important for sure. Thank you for your reply and attention!

That's a good idea for scientific people, or even it's possible to allow a simple interface to join all kind of people too.

The idea it's not change the way of cycling, because I know that the professionals or even who rides a long time, have totally the knowledge of how gears set use, or how relation use for each situation. And I totally respect the opinion about an automatic Gearshift, prefering the manual.
The case is that the amateur cyclist, or the mom who rides twice a week the take her son from school, doesn't know exactly how gears work, and most of them let the bikes in the garage instead of use them, because the waste of physical energy, or the huge effort that they have using just one gear for all situations, don't motivate them.

Also, its directed for people who have difficulties to twist or push a handle in the bike, where the system would be well applied.

I like the Shimano Di2 honestly, but I'm not a professional and most don't as well, that's why not everybody can pay for that. So, a low cost project, wireless, which could do the same or even more than Shimano Di2, seems to be a very interesting idea IMO.

I wnat to thank you all that discussed about it, and got your opinions, the project is based on that and I really appreciate it!

I'm sure many said that during the advent of the automatic transmission for automobiles. It's not a chore it's one less thing for those who are not type A, needle nosed personalities racing about tearing up the terrain and causing erosion in their little bicycle suits to think about.

MUST HAVE CONTROL! Shift when I want to! HAVE TO GET TO NEXT STARBUCKS FOR MORE FUEL! The fact is that everybody isn't you. If you don't want an autoshifter don't buy one but don't dump on those who ride and build them.

Just because you couldn't do it doesn't mean there are many of us who can and do.

That person clearly was never taught to use the emergency brake until the clutch started to engage. I learned that 50 year ago still use it on my motorcycle. Rear brake on as I throttle up and release the clutch.

Personally I don't see the need for an automatic shifting system on a bike, since it's not like it's difficult to shift gears on a bike anyway.

Sorry for late reply.

(a) Arguable, (b) agree, (c) agree.

(a) Some modern auto transmissions have better fuel consumption than their manual counterparts. I used to love pouring over the Gov. of Can. car fuel consumption publications, and automatics started catching up with their manual brothers more than a decade ago.

My Mazda (six speed manual) gets slightly worse mileage than the auto version, but that might be because the manual has different ratios. I enjoy driving it in busy city traffic a bit more than the auto transmission car it replaced, and much much more in more interesting driving scenarios.

I don't see a need for it but then again that was probably said about automatic transmissions on cars. If they can make it work properly and it becomes an option on bikes and convinces some people to ride bikes then why not? As long as you can still choose manual shifting.

I can drive stick shift and I do enjoy it in some situations but hate it in traffic. Gotta try something a few times before you rule it out. I know a lot of people who would never drive a stick shift under any circumstance and to me based upon my experience with it they are missing out on a bunch of stick shift positive situations. But if auto shifting can be done right and converts some folks to riding bikes, then more power to it.

First, I hope someone invents flying bikes with automatic gear shift. I won't miss the good old days a bit. Next, I would prefer that no new people start biking, the paths are crowded enough.

if more people start biking then fight for bigger paths instead of wishing less people biked.

Yes, Jersey City is known for wanting to pens tax money on bike paths, as are most towns.

Why do you care how many people bike? Do you have some monetary interest in selling more bikes? I think biking is like any other hobby or sport. Those interested will find there way without automatic shifters or flying bikes.

Anyway, ET didn't need a wider bike path.

On a related note, some here could use a little bigger sense of humor.

Downtown Jersey City, where I live, has a ton of bike lanes. can't make a turn without finding one. And last year we joined up with NYC's bike share program, CitiBike, and launched it all over town. In the last 2 weeks we added 15 new CitiBike stations around town. Considering our proximity to NYC it's a match made in heaven since most folks that live here commute to NYC. Ride your CitiBike to the PATH station and take that into Manhattan, then hop on another CitiBike and ride to work. It's quite perfect. Unfortunately other neighborhoods don't quite have the density of bike infrastructure as downtown JC does, but that is being worked upon.

I have zero financial interest in more people hopping on a bike. I could care less about the money. I do have mine and other cyclists' safety invested - the more cyclists giddy up, at some point more drivers become acclimated to them, the safer it gets. Rinse and repeat. I also believe in the bicycle as a means of transportation or exercise that is overall a positive influence on the environment around us both in regards to pollution, climate change and individual health.

Some people will find their way to bicycling no matter what we do, that is correct. But plenty of people need a nudge to change their ways even just a little bit or to try something new. Nothing wrong with giving it to them if done politely and ethically.

Maybe ET, wherever that is, needs more bike lanes not wider ones.

I've seen numerous people on here whine about 'more bicycles' initiatives bemoaning that it will crowd up where they currently ride. Hard to tell when they are kidding or not in a non-verbal environment.

Seriously? You don't know who ET is?

ahhhh yes the lovable BMX flying alien that takes an XXXXXXXXXXL bicycle helmet. I thought you were talking about a place not a who so my mind went to geography not fictional movie creatures

So don't buy one. That's your opinion. Others do see the need for it. Always in the right gear with a smooth up or down shift and no error with shifting too soon or too late..

Don't worry, I won't.
