is there any HIGH quality throttle ?

Post by levleon13 » Dec 30 2016 9:01am

like, half of the world creating crazy electric machines that cost enormous amounts of money , but when you look at the handlebars you see these cheap 10$ throttles that look like theyre gonna break into pieces any moment ( me myself using one of these ) . so i wanted to ask you if theres any high quality throttles to buy anywhere ?

look up domino throttle or Magura, they can be difficult to source though

they looks nice , but is there any quality thumb throttle opt ?
i would like to have the option to change grips by my taste , and not just plain black .

Cable throttle from a motorcycle, wet bike, quad, etc. Cable goes to ,,, yep,, same cheap ass throttle.

I'd love to see a much more fine control hall throttle, made from more indestructible plastic than pvc. Or maybe just better pvc. Something that would give you real fine control over the 0-100w, then go to more like a normal response. Two halls in the thing? something like that. Like it automatically runs a two speed switch. First 1/3 turn is low power, then it ramps up for the rest.

Something in between around the $50 mark would be good, not seeing much in this market

You can change them you just need to use motorcycle grips. Throttle side has a larger ID. I use Magura throttles and love them. I change grips all the time. I generally use motocross stuff, lots of good options.

And there are good ebike specific throttles. I recently purchased a half twist for my wife's bike and it's very nice. It feels like it's better quality than a Magura actually. Chinese stuff is a crap shoot though.

I agree most are complete crap and mine got stuck in full acceleration after coming apart in my hand.

With the popularity of 3d printers, there should be someone making custom throttles with quality plastiques!

not exactly high quality but cheap and mine has working great so far! I run this with my normal robust motorbike cable operated throttle

That looks very similar to the one on a Sur-ron. They work fine.

That's a software issue, it can be got around in hardware (different shaped bellcranks, linkages, magnet positions etc.) but it's so stupidly simple to do in software that it should really be available in any controller configuration by now.

Cheap is good, if it works fine. Buy a spare or two.

zombiess used to make something called the throttle tamer, that did something like that:
viewtopic.php?f=2&t=32599
viewtopic.php?f=31&t=51460
within that thread adrian_sm posted code and a schematic to do some various throttle response curves
viewtopic.php?f=2&t=32599#p473944


also, some notes by me on throttle issues / designs are in this thread
https://www.endless-sphere.com/forums/v ... ?p=1449128
especially "runaway-proofing" etc.


i have ideas in my head for a machined-metal throttle body/grip/etc, along with the dual-sensor and "translation electronics" that would include adjustable throttle curves, etc., with a little usb-drive-sized box that connects to the throttle connector of a controller. usb to a pc to adjust the curves (bt to a phone app would be nice while i'm dreaming). but i don't know how to actually do most of what this would need, and i haven't found anyone that could that's interested in such a project (since it would likely be expensive enough to make that not many people would buy one, so it probably wouldn't be something a profitable business could make a go of).

The electronics are easy enough to do with single sensor but for an extra 0.50 cents or so it would make a lot of sense to use dual sensor as it would allow error checking. Setting can be very simple. Usually there'd be 2 point calibration, throttle closed and throttle full with a straight line between them. Add a 3rd point at 50% and a curve can be calculated, twist the throttle just a little for that point and it would have rapid increase at low throttle and fine control at high and the opposite if 50% was set at a wide throttle opening. Fancy curves can be done but it means a slightly different approach and depending how it's set it could add any amount of complexity, there'd be far more code needed to talk to another device than the throttle code.

An arduino would be ideal for the job but only because they're cheap and easy to get, they're way more powerful than needed and it could be done with a much smaller microcontroller (very small, matchhead size) but that would mean more specialised parts. Analogue output to the ESC would be the biggest challenging, ideally it would be a digital signal (CANbus or I2C usually) but analogue output can be done, it just means a few extra resistors and capacitors. If you get around to putting something together then the firmware would be no problem, I'd be happy to do it and there are literally hundreds of thousands of folks that could write it in less than an hour

if i were to do it at all, it'd have to be dual sensor, becuase there have been way too many runaway bikes and the like because of broken grounds between throttle and controller, and this would fix that. with this, a broken ground wouldn't result in the signal being pulled high, and thus a high (possibly full) throttle signal to the controller.

there's other stuff it fixes or prevents, but i can't remember what, right now. :(

Usually there'd be 2 point calibration, throttle closed and throttle full with a straight line between them.
if it's designed right, mechanically, it shouldn't need calibration for each unit, only for the master that the programming is created on. it just needs to be precise enough in placement of the halls and the magnets.

but the option could be left in the software to redo teh calibration on any particular unit.

Fancy curves can be done but it means a slightly different approach and depending how it's set it could add any amount of complexity, there'd be far more code needed to talk to another device than the throttle code.
i'd use a usb port on the mcu board for programming it, and have a pc program (windows, at least, dunno if apple is possible, but if a browser or java app can send data to a serial port the app could be done that way?) setup with a graph for throttle voltage vs rotation percentage, so that any user could simply draw the curve they want, or select from a number of common presets. and be able to save / export / load curves, for laoding on multiple throttles or trading between people, etc.


An arduino would be ideal for the job but only because they're cheap and easy to get, they're way more powerful than needed and it could be done with a much smaller microcontroller (very small, matchhead size) but that would mean more specialised parts.
i don't recall which mcu zombiess used, it should be in his throttle tamer thread. i don't know if that mcu is enough to do the stuff needed, especially usb (or serial) to a computer for user-end programming.


Analogue output to the ESC would be the biggest challenging, ideally it would be a digital signal (CANbus or I2C usually) but analogue output can be done, it just means a few extra resistors and capacitors.
the digital outputs would be a great option...but since almost every available "low-power" (say, under 3-4kw :lol:) controller still uses analog input, this unit also has to have that same analog output, able to emulate a single-hall-throttle voltage range (but programmable to emulate any voltage range).

there is also the possibility of having it emulate a pot throttle, because maxim (and probably others) makes digipots that are controlled with a serial digital signal. (i have some around here that were going to be used for something along the lines of the beamts torque sensor, before that existed, or at least before i knew about it, a decade or so ago). so that could be an option in the design and code, along with the canbus / i2c output).

for instance, the stuff i have now is all standard hall throttle inputs, including the cycle analyst.

but at some point i'll be building a lebowski controller pair; iirc that uses canbus to talk to each other, so maybe it could use canbus throttles (haven't looked into it).

i appreciate the offer. :) i've been trying for literally decades to find people willing to work on various projects, and so far have had just two positive responses other than yours, neither of whom ever ended up doing the projects in question.

most of the projects have been more or less simple in concept, but complex (sometimes very) in detail. there's a number of them i'd still be able to use, if i ever got to make them. (but few, if any, would have any commercial use, and i can't afford to pay anything for help on them--i can only trade for whatever help i can give on others' projects).

I have lots and lots of ideas, including ideas about other people's ideas. :lol: i'm terrible at actually *making* things, though--what i do is crude prototyping at best. as far as coding, i know the basics of programming in basic, and assembly, and that's about it. i know the concepts behind it....

*this* project does have commercial uses...but i don't really have an interest in starting a business. ;) i just want a good throttle, and would like to design something that could be opensourced and used by whoever wants to make themselves one.
