If ignore about it’s a saw and could be harmful for kids, it might be an energetic toy.

It’s called “science”. We (as hackers and scientists) are critiquing it, and rightfully so, because it’s one of the most stale and boring things seen on this site in a good long time. Also, because the design is total crap and has been around for almost as long as the internal combustion engine.

So much negativity.
The machine is crap, no doubt about it but it works and the young man that built it had fun and learned somthing. good for him!

“or, you know… you could just buy a scooter”
“and you can buy kits to do it way better”

these sentences can be applied to almost every hack on this site, but that isn’t the point. i don’t care if i can buy a good quality headphone amp, or an ipod charger that runs on aa batteries. this site exists to show how to make such things yourself. you’re talking about hackaday as if it were digg or gizmodo, which it certainly isn’t. if you don’t like the content presented here, either submit articles you think are worthwhile, or leave.

just as a FYI, if you move >25 mph or so you can put a SMV tag (Orange reflective triangles) on dang near anything.

“If all your going to do is complain, stop coming here then. Make your own site and post whatever you want.”

translation:
“waah waah all i want is a 24/7 circlejerk about how everything posted on hackaday is totally awesome and should never endure criticism”

tjhooker wasn’t being a righteous cunt, he just stated the fact that this is nothing new or particularly interesting (it’s as old as the gasoline engine) and you can buy kits to do it way better.

I thought it was clever how he maintained pressure between the spindle and wheel. A door hinge and turnbuckle is a very solid design.His throttle control was pretty spiffy as well.

Also, for a lot of chainsaws a spindle would actually be a very decent way to power it considering that modern chainsaws run at about 12-13000 RPM. So, say his bike has a 16 inch tire and the spindle is 1.5 inch in diameter that gives him a 10.67:1 ratio and a theoretical speed of 53.6 mph@12000rpm although losses included he probably can get up to 30mph. Not too bad.

My impression was that this was Hackaday, not Innovationaday. Maybe this is not new technology or technique, but it’s certainly a hack. I don’t get what people are complaining about.

The fabrication is all custom. Some of it it pretty smart – like using brake cable for the accelerator since most frames have cable bosses incorporated into the frames. And it seems that all the complainers about friction drive overlook the fact that his design was a quick, easy way to motorize the bike and keep use of the pedals, a good idea if the rig breaks or he runs out of fuel.

I’m glad some of you can buy a kit for $200, but how is that a hack? This rig could probably be built for about $40 in yard sale finds, or for free if you have a well-stocked yard shed. Yes, it will wear through tires quickly but this looks like a budget/fun project, and around here, you can get free tires from the local dump all day long.

I dunno when the posters on this site got all negative, but it’s a bummer. If you don’t like a hack, you could be a heck of a lot more constructive in your criticism, or move on to the next article. I didn’t read a single complaint on this page that couldn’t have been phrased constructively. How about supporting the hack community instead of putting people down?

Kudos to Geoff390, I think this was a pretty interesting project.

Lame. How about checking out endless-sphere.com/forums

They have more innovative custom ebike than this wheel eater. Not only that there is the battery section in which they’re designing a Lithium battery BMS system. At the same time we’re hacking up powertool battery to run ebikes, now that truely deserve an article on hackaday.

@damien, the problem with that is the concept of reinventing the wheel is kinda cool (where this thread is not). Someone has already reinvented the car tire. Very cool design, uses the same traction but rubber springs… or something instead of air.

Saw it on Futuretech. Can’t remember the name of it tho. I tried to pull up a link.

@anonymous “Bunch of damn trolls”
Sometimes I really believe that Hack ‘A’ Day posts stuff like this just so they can get trolls. Stuff like this isn’t going to turn anyone, interested in most things on the site, off. But, I’m damn sure it made a whole lot more people than just the one’s who’ve posted so far, to go “WTF WERE THEY THINKING!”

@TJHooker: that’s fine just don’t be a righteous cunt about it.

It’s like a big piece of shit. next day some guy will show us how he succeed to build a wood wheel, BUT with a brillant idea to add a steal tire to avoid friction. It’s the wonderfull fashion of DIY ! Sometimes it’s awesome sometimes its just a piece of shit)
