[@exgenica]

Word of caution on buying a replacement throttle. I just saw some throttles for sale online, claiming they were compatible with ebikes. But a short line in small font buried way down the page lists a spec that says the Hall sensor signal varies from 0.8V to 2.4V However, 2.4V is *not* a sufficiently high-end Hall sensor voltage for most ebikes. Also, most people probably would either not see the 0.8V-2.4V spec and/or many people would not even know what it means and would ignore it assuming it was normal. Unsurprisingly, there were many reviews from buyers that were disappointed the throttle didn't work after they installed it. From what I could tell the sellers didn't seem to care that this was a major issue and likely aren't going to change their web pages to make it more obvious or provide a warning about this lower than required Hall sensor voltage output for ebikes. With a simple change to the web page, the sellers could save a lot of customers the frustration and grief of spending time and money on trying to repair or build their ebikes using these ultimately unusable throttles.

[@Zomby_Woof]

It's not really the seller's fault. What you are describing is someone unfamiliar with how ebikes work, doing repairs on a commercially produced bike. Anyone who has built their own will either know what range is required by the controller, or will be programmable and the throttle will work fine. If you buy a conversion kit SAVE THE DOCS THAT COME WITH IT. It's often nearly impossible to get ALL of the original specs, as the seller is typically bundling compatible components from multiple vendors, and often doesn't keep track of spec changes from a previous run.

Hi EV you look like you know your stuff, I have 2 Basic (no gauge) e bikes with throttles, I wanted them to be motor assist exercise bikes (only use twist throttle to help when needed on hills), one converted easy by removing the sprocket sensor to stop peddle assist, The other one is crazy. It has a 2 stage throttle, it works from stationary up to 5mph then you have to peddle to 10mph to get the throttle to work again (of coarse peddle assist comes on "flat out" too) and you can stop peddling and it works like it should . If I disconnect the sprocket sensor I cant get motor help over 5mph. It seems to get a spike from the sensor to work. Grateful of any ideas . Cheers Dave

I am curious to know if taking out the hall sensor "chip" is really just that easy as in video? It seems like the two throttles I have tried with have NOT wanted to pop out of the slot / housing of hall sensor. are they ever glued in by manufacturer? Or am I doing something wrong? Thank you:)

Hi, i have thumb throttle that have start idle voltage 1.33v and when full run 3.42v, is this ok voltage, is this throttle ok and will this throttle work fine with such voltage values?. Thanks 🙂

[@SnakePlizkin]

I tore off 3 of the 6 wires on my mothers bike when i tripped and i grabbed on to it... First i playned to resolder them but the housing can't be taken appart without breaking it. Have been looking around everywhere for a new throttle with 6 wires but i can't find one. The only thing that was printed on the throttle was "DE PU 25.9v". Only other thing i noticed about the throttle is, that it is progressive/stepless twist throttle. Some advice would be appreciated.

​@@isaacogedegbe5557It's usually going to be the controller. I've had a controller fry from a random short. Display is normally an optional component. There are usually 3 of the wires that connect to the display that are manipulated through the display to actuate thr desired assist level, but other than assist level the display isn't usually required to run the bike. The BMS can also cause failure to power up, but it can be temporarily bypassed for test purposes.

[@jacobclark89]

I've been experiencing extremely dangerous episodes of the motor not stopping as soon as I turn the throttle , related to high humidity conditions ! I think it's because the humidity increases conductivity of the hall sensors in the throttle . can you recommend a good throttle ? I think the manufacturers are going to have to make them water proof. I experienced the same issue with a different throttle , battery and controller. just using the bike after a rain storm is enough to cause the issue.☠️

so the S49E hall effect transistor is actually a pnp type transistor?

No... PNP transistor is different thing, this transistor working with magnet's, on two pins you need power and from the third pin you have analog voltage output, when the magnet is close output voltage is high when magnet is far there you have minimum voltage..

Hi, first of all, thank you for this very usefull video. I have a problem with my e-quad throttle reaction, I have 4 different throttle, one finger type and three twist type, I measured the output signal as you discribed and didn't see any major problem but the motor driver doesn't give any response during the first angles of the throttles, but after the first 4-8 degrees, the motor starts to spin with a higher speed than desired and it makes a bad feeling on driving characteristics of quad. Between the 4-8 degrees to max throttle, there isn't any problem. Because of this issue, I can't drive the quad at very slow speeds below 5kph. Do you have any suggestion to fix this issue? Thanks. I checked this issue with another motor driver as well, and the result was the same.

[@Zomby_Woof]

Was a component changed around the time this started, or has it always been this way? If it's always been this way or started.when a component was changed, its.more likely than not the order of the halls - try changing them by swapping any two. It could also be the phases not in correct order.

You have not explained how you connected 3 wires to multimeter.

[@luvdr350]

One is injecting voltage simulating there is power going to the throttle.

[@Zomby_Woof]

From your 5v p/s to the black and red wires, positive to red, negative to black. Connect the meter positive/input to positive junction, common/ground to the green signal line. The meter positive could be labeled different things. You can't count on meter cables being plugged in correctly, but Common/ ground is normally the black probe, and the red goes into the other port, assuming you don't have a port labeled "up to 10 amp" or similar - it's for a kind of current measurement - not used for your purpose. When the halls are active, they cause variation in how much is not drained to ground, and instead flows to the green signal line. Basically, current flows from positive to the throttle, where it is split and part drains to ground and part goes through the green signal line, where the controller interprets the variation as a command to increase or decrease power. The absolute value of the variation doesn't matter as much as that there is some range. They don't normally fail with a low signal, normally no signal at all on a throttle. The halls in a motor are a bit more complicated.

with black ground wire must work, if not find 3 pole switch to disconnect on same time 3 wires.

[@exgenica]

(00:45) "...output we must get a range of 0 to 5 volt" Not always accurate. Some throttles, including those using the common "49E" Hall Sensor and a Vcc=+5.0V, may have an output signal that does not reach 5 volts. The difference can be up to about -0.5V. So, the real-life operating _range_ can actually be from slightly above 0 to just approx 4.5V. My memory suggests I've generally seen upper voltages top out at and flatten to about 4.8V. The controllers still interpret this voltage to run the motor at maximum speed, so there is no loss in performance.

[@EVCustoms]

Yes i agree with that...
