Invention Makes Citibikes Electric 166

An anonymous reader writes "Inventor Jeff Guida has come up with a way to turn any Citibike into an electric scooter. His ShareRoller is about the size of a small briefcase, weighs just seven pounds, and has a 12- to 20-mile range. From the article: '"Years ago, I would've needed a giant engineering company and several million dollars in development research and it still would've taken two years or more," Guida said. But 3D printing has changed all that. In the coming months, Guida hopes to design a universal bracket so that the ShareRoller can be used on any bike. He has some competition there, as there are a few companies that make wheels that convert regular bikes into electric bikes, but he says the ShareRoller is more convenient.'"

    Is there a citation somewhere for this mythical multi-million dollar two year scooter conversion kit? Or this just another way to totally blow 3D printing out of proportion to what it can actually do?

    Look, years ago I saw some guy cobbled together a chainsaw motor to friction-drive the rear wheel of a pedal bicycle. No giant, multi-million dollar two year project there, and no 3D printers either.

    This incessant trumpeting of 3D printing as some kind of revolution is tiresome.

    The point is no one needed 3D printing for something so fucking obvious and simple it was made a hundred years ago. And it certainly never took two years and millions of dollars either. I'm just tired of the continuous cock-gobbling jizz-splash every. single. fucking. time. someone made something and then claims how radically faster and better everything is because of a 3D printer. And there's never any evidence for this except that we have to take someone's word that the human race was completely and utterly incapable of putting a fucking rubber wheel on the end of a shaft before.

    Chainsaws are cheap. The other day I walked behind a warehouse and there was an electric one jammed blade-deep into an iced-over snowbank.

    Some of the ideas put forth are old. Motor assist for pedal bicycles has been around practically since small gas engines were available. Electric assist is newer, but still not by much. Battery and solid state technology are making it much more capable than what we had even a few decades ago.

    What is interesting is combining all this into a unit which can be installed "in seconds". That opens its use up to some applications for which motor assist may not have made much sense in the past.

    Oh, and all the carping about 3D printing? Sure, its not economic for mass production. But it has its place for smaller shops who need too knock off a few prototypes quickly and cheaply. Once the design is finalized, more traditional fabrication techniques can be used.

    It mentions 18 miles per hour in the article for the top speed, but I wonder if that's for 'not' or 'barely' pedaling. Can it take somebody with a max speed of 15mph pedaling on their own and get them up to 20 if they're really working at it?

    but to fat and lazy to actually ride a bike enough to be in good enough shape to travel 20 miles without breaking a sweat.

    Consider that there's a lot of work and sweat between 'fat&lazy' and 'slim&active'. Most people have limited choice about distance from work. A device that gets them started, to actually do it, can be of great assistance. I know there's a few hills where I would have liked this thing just for that spot. I'd still have to help it up, of course.

    What about the guy who needs to travel 30 miles, and this is the difference between him biking and driving?

    In other words, biking shouldn't be about exclusivity.

    Selling millions - Not if it can only fit on one bike type. Fix that and maybe.

    If you don't have a shower at work or a nearby gym, you can take what bicycle commuters call a "bird bath." Shower in the morning before you leave for work so your sweat won't smell (much). When you get to work, wait until you stop sweating, then find an empty bathroom stall and wipe the sweat off with Rocket Shower, unscented baby wipes, or a wet rag with a little soap. Then put on some fresh deodorant and a change of clothes and do your hair.
