who needs to shift?

Trek introduces an automatic shifting bicycle:

"It's easy, you just hop on and ride," Correa said. The bike, meant for recreational riders, shifts through three gears using an electronic shifter in its rear hub and powered by a generator in its front hub. Though Correa had a few reservations, he was impressed. He liked the bike's retro styling and ergonomics--an easily adjustable seat and handlebars make it comfortable. He had to get used to not reaching for the gears, but said, "It can really handle the hills."

I don't know -- I like being able to decide how hard, or easy, I want to take a hill.
