I'm not sure who's seriously interested in most of these features, fun factor nonwithstanding. One of bicycles' strengths is simplicity of critical elements, notably the gear switching. How do they make sure that the electronic system doesn't die on the rider when the battery goes flat? How do they deal with increasing slack in the lines? Who really benefits from turn signals? Unless they are mounted on special stalk…

Unlike others on this thread, I love where this is headed. I'd love to have a really smart bike. However, once I have that much tech on a bike, it would be impossible to park it anywhere without the risk of being stolen.

It's already impossible to park a non department store bike of any value anywhere in an urban area of the United States without the risk of it getting stolen. It's probably one of the factors in why some people might not commute for errands even if everything else was favorable - a bike decent enough to warrant a ride is a target for thieves. The bike thief community in San Francisco/Oakland/Santa Cruz has been thriving since all the locals I know here have been kids in the 80's (when Lemond revived the upscale bike industry in the USA.)

The grumpy old man in me likes my bike to be as mechanical as possible, I don't want to remember to charge my shifters, power meter, gps, etc. Maybe that's why I still ride a 1989 Trek 1200 with down tube shifters and biopace chain rings.

Even having gears at all can be a bit annoying, with the newer groupsets having a million gears in the cassette and proprietary chains. I really love my fixed gear.

Lots of negativity in here. Most bikes with DuraAce components already aren't the sort of thing you'd leave out on a city street unattended.

One cool thing that stood out to me was that these monitors will transmit data over ANT+ or Bluetooth. As someone who already tracks all my workouts w/ a Garmin watch, I welcome the ability to track more metrics like power output. Gives you a good way to objectively track your progress over time when training for events and can help you gauge the impact of sleep, alcohol, etc on your performance.

Though I made a grumpy old man comment on this thread, I understand that some people want more tech on their bike and that's fine too, if it gets you riding more.

I just worry there will be a bit of a donut hole problem. Where at the high end you have super smart bikes with electronic everything and on the low end carbon steel big box store bike and nothing in-between.

The whole point of electronic gear switching is that there is no slack in the lines - the shifters communicate wirelessly with the derailleur and the derailleur uses a small motor to execute the gearshift. It's actually awesome in practice - gearshifts are crisp and perfect each time, without the need for frequent adjustment or dealing with issues such as cable stretch and dirt. The batteries last a few months and if they die, you're stuck in one gear (you can change it at the side of the road with your hands if you get stuck in an undesirable one) - no big deal.

For a commuter / daily-driver bike without weight concern, I think a belt-driven internal planetary gearset with electronic shifting would be ideal as the bike nearly becomes a sealed unit, without any exposed grease or need for lubrication or adjustments.

Earlier quoted context omitted.

Turn signals can help folks that have to bike up a hill and want to indicate they are turning. :) For the rest, I agree it increases the failure likelihood, but it is probably heavily mitigated in some cases by the fact that most of the power can be generated by the biker. These are not large gears, so the shifting capabilities probably don't require plugging in. And they should "fail to on" such that if they go dead…

Turn signal would be useful. Just yesterday morning I was almost hit by a car when I was merging from bike lane to left turn lane.

You can just use your hands to indicate your intention to turn, this is done all over the world and AFAIK the accepted method of indicating without having any electronics.

Anything you strap to a bike has to be reliable. If there is one thing you can say about mechanical systems it is that we know how to design them so they last the lifetime of a bike (wear parts excluded), anything electrical or electromechanical will have a shorter life than the equivalent that uses only mechanical parts. Just look at your average bicycle light set, even after I don't know how long we still can't mak…

> Just look at your average bicycle light set, even after I don't know how long we still can't make a set that lasts more than a couple of years. You're probably right about the average bike lights. But the good folks at Light and Motion make some incredible products. USB-rechargeable, bright, easily removable, and pretty durable in my experience. http://www.lightandmotion.com/

Seconding this, they make a rear light so bright my 94 year old grandfather can see it in daylight.

Fix gears are fine as are non-fixed single speeds, but I need my variable mechanical advantage for hills, maybe if I lived in Chicago I'd be all in for a fixie.
