    The Alpha Bike

    The Alpha Bike



    The Alpha Bike, designed by a group of engineering students, contains an entirely internal drivetrain that allows riders to switch between fixed-gear and multi-gear setups. The simple switch is enabled by an electronically controlled clutch, part of the Switchable Integrated Free-Fixed Transmission (SWIFT), discreetly hidden in the bike's frame. Populating the front hub are a drum brake and a dynamo, which juices the bike's electronics -- the back hub contains a three-speed gear set, put in motion by a simple push-pull cable. When the front wheel starts rolling, an LED screen mounted in the carbon fiber handlebars is illuminated, displaying time, cadence, and speed, among other things -- this data and more is stored on an accessible SD card.

    I'm not very interested in any of that stuff and I have doubts about how practical it all is. Never-the-less, I think that it's cool that they built it. You have to have a prototype design before you can turn new ideas into a practical design.

    I voted FTW and I'm a non-repetant retro grouch.

    I like the enclosed chainless drive and the hub brakes, not too sure about all the electronics though.

    Looks pretty cool, I'd ride it. I can always appreciate student engineers who dedicate their projects to bicycles - this helps everyone.

    Looks like an engineering exercise rather than a practical bike. Engineers tend to fall in love with techno-stuff for its own sake.
    I'd like to know how this 3-speed is superior to existing 3 speed hubs.

    Want to impress me? Work on the bike lock problem. Secure, lightweight, compact, durable in an affordable package.

    Looks like its just a garden variety Sturmey Archer 3-speed hub:

    The integrated clutch in the bb is the inspired bit.

    I needs me one of those computer-controlled milling machines. Tthe bb shell is beautiful. The lugs ain't bad either!

    Needs a rear brake though. Maybe actuating the right brake lever switches it to fixed gear mode...

    I have the heart of a young boy. I got it on eBay.
