  • Because you cant spell Mechanic with out Metallica!

  • What's to stop it from beating the hell out of you if/when you go down a hill that causes you to move faster then you can pedal?

  • What the... WHY?! This would weigh far more then a chain...

  • @TheGr8scott Less messy in bad weather?

  • Have you seen the bike at bullcityswagger com ?

  • well it sucks a bit much

  • hahaha patent are pointless i can copy this but not sell it so yeah good luck with me buying one of yours :L

  • Interesting, yet a bit pointless.

  • Damn patents! I had this idea about a week ago, thinking about how some energy gets wasted in the legacy configuration. I want to make one, but am I even allowed to now that you've claimed this as so called 'intellectual property'?

  • Nothing new, I rode one on the Gold Coast in the early 1980's. Identical setup. His was not new either, and went the way of the dinosaur. I will say though that it was extremely efficient once you got up to speed. it was on the local news. I don't know why it never caught on. Have you done a patent search?

  • The point #22, where the rod is attached to the lever. If it was slotted, and allowed to move in and out (up and down), would change the effort and distance you applied to the pedals. I think that at low speeds, the rod would be closer to the pivot, and the pedal would have to move further with less effort?

  • Metallica!

  • Nice design, would the in hub gear have those gear ratios if it was put in the front wheel and had pedals attached? Just curious, i would like to make a flevobike that had an in hub gear system but only if it could flywheel... and maybe a coaster break. So far only Coaker has something like this but its on a mini pennyfarthing so the gear ratio would be shot on a smaller wheel.

  • Good idea but you can't free wheel... Can u ?

  • @WayneDavisRocks brakes

  • @fairyheli2 I guess what I mean to say is if the pedal assembly is connected directly to the moving rear axle then the faster you pedal the faster the wheel turns but by nature if you need to stop pedaling your out of luck because like a gib wheel, the pedals keep moving, if your foot comes off the pedal then you'll have a heck of a time getting your foot back on the pedal without a shin scrape or 4 lol, just my observation

  • @WayneDavisRocks ...at a guess, i'd say... by installing the same sort of ratchet device to the hub of the drive wheel, as you'd find on any other bicycle O_o

  • naja. den zweizylinder-kolbenstangenantr­ieb gibt es schon seit der dampfmaschine. und eine nabenschaltung dahinterzuschalten ist nun wirklich keine geistige höchstleistung. Nett scheint mir die umgehung des totpunkts durch den etwas längeren hebel auf der pedalseite. Das gab es bei der Dampfmaschine bestimmt auch schon.

    Vieleicht stammt ja wenigstens die klavier-improvisation von Dir :-)

  • Look like orbitary gear set.

  • i think there would be benftis from having a double drive chain system for bicycles. left and right chain rings on the front and rear. so basically a double system of what we have today,. 2 rear cassetes one on each side and two cranksets one on each side. that would increase efficiency

  • there really are some gratuitously unpleasant people commenting on You Tube. I think your idea is fresh, exciting, and fascinating. Good luck with building the first working model, and don´t let the haters get you down  : )

  • Are we going back on the time line?

  • Clever.

  • yeah those longs wouldn't catch on anything - not

  • I'd buy that.

  • Yah good luck with that one! Ha!

  • @leaualorin I suggest you do educate yourself a little bit about chain drives, they are significantly less efficient than a gear drive. Just ask BMW why they replaced the chain with a gear drive. And in case of a BMX bicycle, riding off road in wet conditions, your chain efficiency drops to as low as 0% and most races are lost or won on the dirt build up on the chain. The gear efficiency stays constant at 99.8% under any condtion.

  • How do you get away with calling this "A Novel New Bicycle Drive" ? Your lever drive appears to be a direct copy of lever drives installed on ordinary bicycles in the 1870s.

  • @rickpaulos I'm sorry! my bicylces is totally diference to the penny farthing or ordinary bicycles of the 1870's! I do not drive a direct crank on the wheel, and use gears, rather than a large penny farthing wheel to achieve the desired speed!

  • @meiwechner better look back at other historic bikes, this came just before chain gears, you just reinvented something

  • @meiwechner Agreed! In patent law, a significant improvement is the same as a new idea. Have you calculated the mechanism's mass and manufacturing costs? Gotta love innovation.

  • @rickpaulos There's one of these on the wall in a bike shop in Lawrence, KS. search for: Restored 1886 Star high-wheel bicycle being ridden!

  • @meiwechner Not sure what part of a chain/sprocket system you believe is inefficient. Engineers typically measure 98% power transfer efficiency for this type of system. Spur gears are typically figured at 99-98% efficiency per interaction. If you have two gearing reductions in your system you are likely around parity with a chain system at best. If you have more reductions, well, the outlook is not good.

    Yes, I am a degreed, licensed mechanical engineer. Eager to understand your efficiency.

  • As I'm studying engineering, and building a bicycle out of wood currently, this is amazing! The one thing that worries me is that there doesn't appear to be any way to shift, though I mostly looked at the handle-bars when I noticed this.

    Is it easy to reverse? And finally, is there a working model of this?

    Thank you

  • nice

  • What happens to the pedals as the riders stops pedaling?

  • @pilot2b1993 , the same as on any conventional bicycle, there is a free wheeling mechanism built into the hub that allows the drive wheel to spin freely while the pedals stand still; the free wheeling mechanism is clearly shown on the drawings.

  • Very impressive. congratulations. Any timeline for release as yet ?

  • @dieselnut77 Thanks!

    Currently, we don’t have the finance to develop it, and my husband is very busy with many other projects!

  • very  cool, does it have multiple gears?

  • @LTF85199  yes, as many you like, but I have designed a 9 gears concept so far.
