@tnaglassworks I live in the Santa Cruz Mountains where I did a lot of biking for decades, so I know about MTB riding up steep grades. The SIVAT will be engineered to be a great MTB transmission. The overload protection will be mostly for motorized use not invoked for hard climbs on pedaled bikes because pedaling torque limits are well researched & characterized. You'll need to pedal against a wall, standing on the pedals, pulling hard on the handlebars to even come close to overloading it.
@SIMKINETICS ok sounds good then, i once had a 4wheeler with a similar transmission and if i attacked a propper hill, about halfway up it would engage the stall safety, rev really high, and send me rolling backwards very dangerously. i left that particular quad in the woods later after it repeated this many times.
@KenMacMillan I'm redesigning for a bike & pedelec producer to his specs. It will be up front at the bottom-bracket instead of in the wheel hub. For cars, I'll just add a reversing gear, which is simple to do.
@SIMKINETICS very light I think for racing too. Transmissions today are so heavy and do not permit a variations "with no steps" as your device.... they anyway have some STEPS. This permits to select a FINE ratio for racing and everyday use... but I think will be cool to make it possible to have a ratio lower than 1:1. Register your idea man and ask for help if you need. This is a GREAT innovation in my opinion !
@mptrax Thank you! There's another nearly identical video from my channel; it's called 'Automatic Bicycle Transmission (IVT)', and it has nearly 700,000 hits, so you can see many comments there. I've gotten several parties interested in helping, so this will become a product when we get it developed further in partnership with a bike industry player who wants to feature it on his products. We're on our way! Bikes first, then to infinity & beyond...
@g0fvt The SIVAT in a mechanical analog to an electrical hybrid between a rectifier-style SMPS and a switching amplifier. Its interval duration and torque (equivalent to voltage) are both modulated simultaneously via one-way clutches (equivalent to diodes). There might be an opportunity to create an electrical equivalent, but I'm an ME, so it's not obvious to me how to do that. The waveform is not sinusoidal. Maybe a new type of motor is implied. Anyway, great insight!
@SIMKINETICS Thanks for the reply, a very interesting concept, I am not a mechanical engineer, I am a radio engineer, but all sorts of engineering is interesting to me, hope your device attracts commercial interest.
@g0fvt Thank you. The SIVAT has indeed attracted commercial interest! In fact, I'm currently redesigning it now to satisfy requirements for an existing producer/marketer of high-end bike & motorized bike (moped) products. It will likely take a couple of years before it hits the market. This should provide a gateway to other applications too.
@speed01line02rc03 You will have to wait. We will design, build & test prototypes first. A bicycle SIVAT product will take more than a year to become available.
@jorisdekeu This issue is covered extensively on my much more popular YT video, called 'Automatic Bicycle Transmission (IVT)'. Highest ratio can be set at nearly anything by input gearing.
maybe you need to make a video of it working on a bicycle, it will get some interest some guy wanting to invest init will stumble across the video and then you got your self a world wide product ;)
@lazyeye79 Thanx. Note that the chain diverges toward right side; that indicates a 55T/11T chain drive. Effectively, you can thereby choose your true highest ratio by choosing input or output gearing without affecting its ability to smoothly get any ratios all the way to zero!
is there any way that i could purchase one of these impressive transmissions, i wish to have it on my bicycle or a bike with a 2 horse motor, please reply
@hheywire Yes, but it won't be available as a product until after the re-design, prototyping & productionizing. The other video at 'Automatic Bicycle Transmission (IVT)' has 222,000+ hits & 350 comments; if you read the comments there, you'll get gobs of Q & A that should answer many more questions that you may have. The bike SIVAT will be rated for 1.3 hp, but if motorized, its rating is at least 2 hp because of higher speed operation with a motor! Imagine full-suspension, motorized MTB!
@hheywire If we get sufficient funding, it could be next year. That will only happen if the economy gets healthy soon. Right now, most investors are taking very few risks. More likely it'll be 2012. I'll keep pushing, regardless.
How about letting the output perform work? All you have demonstrated is that you are able to change ratio, but NOT that your "transmission" carries torque, or is able to do work. Stupid presentation.
@rudolfo909 Upgrade to functional model is planned for an industrial application; too expensive to prototype without funding. We're working on the funding part now. When built, it will be demonstrated with 'work'.
How can it be "too expensive to prototype without funding" a FUNCTIONAL model? How different can it be to the apparently non-functional model you have in the video? Are we all missing something here? You created the non-functional model using CAD, how much are the extra components required to make it function? A million dollars?
Thanks sebairaf3. We plan to put up a website when we get funded for development of the SIVAT for an application; ether a vehicle, industrial drive or a wind turbine. The planned website will include descriptions of practical applications, a comparative analysis of competing technologies, and typical buttons for links to relevant information. When the patent is issued, an in-depth description of how it works and its specifications for loads, efficiency & test results will be included!
Thank you! Thank you! SIMKINETICS is working on making this technology even better, so that we can make it available to those who can benefit. We want to help save energy in as many places as possible!

If you expect to put this into a car then it needs to go beyond zero to reverse.
