Automatic, Electronic Gear Changing

Smartphone gives bikes an automatic gearbox

 

 

 

Forget bicycles with gears that you have to change yourself: the first wireless automatic gearbox for a bike does it all for you.

The system, unveiled today, uses your smartphone to calculate the best gear to be in for the current pedalling speed – then wirelessly shifts up or down.

It also uses the phone's accelerometer to know when to change down in an emergency stop – so you can pull away afterwards with ease, and will eventually be able to use the phone's GPS capability to get the bike into the correct gear for an upcoming incline.

Kinda surprised it took so long to appear... Guess cutting wires is the deal breaker?

 

I've been predicting this all along. Next step is automated training IDT sessions. Provide parameters: power / cadence / HR / speed and the bike computer (cell phone?) will ensure it will all happen as programmed!

But the system will not know, how fit I am, how much power I feel like out kicking out ... what cadence I like .... it will select gears based on what some nerd thought out .... not for me thanks!

 

Sometimes you just want to drop a gear or two and power the crap out of that hill!
