I installed a hub motor temperature sensor.

I works GREAT !!!
No batteries or wires or software.
Stupid simple, and dirt cheap.

I bought seven of them to get free shipping over ten bucks.

I'm gunna stick one on my controller too.


I was looking at stick on aquarium thermometers, but they didn't read high enough temperatures.
This one is for a coffee cup and reads higher temperatures.

It says that it's for aquariums, but only if you like eating boiled fish. 😂
 
It was 32°C today, but my motor was doing OK.
I think the last stripe turns red if it goes over 70°C ?

I'm not quite sure how it works?
I think it's showing that I'm between 45° and 50° and the stripe is mostly green, so I'm closer to 45°?
It think that it turns mostly red, then the next higher stripe kicks in as green?

I was pretty hot though.
I had to stop in the shade to take pictures.
 
Not a bad idea. 👍

My hub is usually covered with trail dust & debris though, so a strip thermometer would be difficult to read.

Many bikes have a temp sensor built into the hub with a readout on the display. Mine doesn't, so I just do the finger test.

I've been doing the finger test as well.
Now I should be able to compare my finger test to the thermometer to calibrate my fingers. 😂

I don't remember what temperature "Too hot to touch" is?

Apparently, if your motor is too hot to hold your finger on for 5 seconds, then it's too hot.

The only things that I really want/need to carry on my e-bike are a few necessary tools, a flat tire kit, including patches, glue and a pump of some sort, and a second battery.

It's been trying to carry a simple 14# battery that is causing me all kinds of problems recently.

You'd think that a 14# battery wouldn't cause a speed wobble, or break a rack rated for 50#'s.

I'm going to try to mount my battery to my top tube, to help stop the wobble and get the weight off my rear swing arm.

I've been messing around with moldable plastic beads to try and make a battery bracket.

I can reheat the plastic and remold it until I get it right.
You can work it with your bare hands because it's not to hot to handle before it hardens.
 
Hey dude, have you tried to increase/decrease your tire pressure? It makes sense, to me, that the added weight would effect the tire pressure. I haven’t had that issue, so I haven’t tried this method. Maybe that other user (nveloader?) in the other thread, has more helpful info.

You could kill two birds with one stone and attach this temp sensor: 😁

Maybe you could modify one of these from Grin Tech. It provides a sturdy screw on mounting point for a multitude of applications:

How do you like the SteerSropper?
 
I didn't like riding with only one battery, so I put some effort into those plastic brackets I was working on and took it for a test ride,..

It works Great !!!
And No More Shimmy.
I was trying hard to start a wobble and it didn't happen.
Getting the 14 pound battery off the rear swing arm and on to the top tube made All the difference.

I coated a strap with molton plastic and wrapped it around my top tube to help secure the brackets, then I used Shoe Goo to glue them in place.

I'm still going to glue the strap tabs to the top tube, but everything help in place perfectly.

They look pretty Oogly at the moment, but I've been heating them up with a hair dryer and reshaping them, so I can mold them up nicer then cover them with black silicone so they don't show.

I managed to carry all my necessary tools in my pockets, even ⅓ of a bag of Flat Out.

I like the way the new Flat Out comes in a bag now.
It's way more portable and takes up less space.
I could probably strap a bag to each knees to make knee pads. 😂
 
Biktrix sells a battery bracket but it is a couple inches longer than the battery and I don't have the space.
And it would also have to be mounted to the top tube somehow.

These are the plastic beads I bought.

They work pretty cool.
I did have to mess around with it quite a bit to figure out how to work with it.
It's like modeling clay meant for artists, and I suck at art. 😂

It doesn't stick to itself very good unless both surfaces are melty so I heat it up with a hair dryer until it starts melting (it turns clear) then stick more to it.
It doesn't bond to the straps, so I had to coat the straps and press it in place with the battery.

And it melts at 60°C so it's not too hot to handle and I won't set my battery on fire trying to melt it in place. 😂
