Smartphone allows auto shifting?

Manual or auto?

–a question that people often consider when buying a car. In these times of high gas prices, a lot of people do consider giving up the comfort of an automatic transmission for the sake of an extra couple miles per gallon. But what about bicycling?

I prefer to ride a single speed because they have cheaper parts to replace and are easier to maintain than a multi-geared bike but sometimes I do ride my road bike. I’m not sure if I feel like there’s a need for me to shift automatically or electronically but nonetheless it is an interesting concept.

I recently read an article on about a smartphone that enables automatic shifting via bluetooth with Shimano Di2 shifters. It was encouraging since it seems like bicycle technology is progressing and although I don’t think a lot of the technology introduced is needed, I do appreciate it because the contributions of anyone does lend to making bicycles ultimately better.

Here’s an example of what the engineers are trying to do:

“The prototype has been tested on a simulated “rolling road” with few complaints from riders, who can customize the shift points depending on what’s most comfortable. Already, engineers are working to improve the setup, with plans in the works to use the accelerometer in a smartphone to change gears in the event of emergency braking. A similar system could also prevent locking up the front wheel.”

In Bluetooth “manual mode” (I’m not sure if touching a button is any easier than “tapping” a basic shifter on a typical bike) but the system does allow collection of data to make trial runs better. The engineers also want to use GPS to inform the system of upcoming hills which enables the system to shift before you need to.

To the average commuter, a system like this would be outrageously excessive but imagine being more efficient with your commuting time. I used to take pride in riding 5 miles in less than 20 minutes but I would be sweaty from pushing myself. Not considering cost, a system like this, I think, would be welcomed on my commutes that are more than a couple of miles since I could probably commute in less time without having to push myself so hard.
