Is it steel or aluminum those are made from @StarTrak |
I could weld it back together if was steel |
Then grind it back down |
Alloy |
Fack |
Why won't epoxy work |
To thin and not much point of contact |
Correct |
And the structure is already fragile on the edge |
I can't see a crack, but no epoxy is not gonna fix that.. |
You could try making a HUGE bevel there, if the crack is in the corner. But I honestly doubt its going to work. *maybe* some of that multialloy braze might.. in a huge bevel. |
for $35 it hardly seems worth it however. |
The crack goes right around in a circle, hard to see from that pic but you can make it out |
And yes, its absolutely some very cheap and brittle aluminum alloy that makes regular old 6061 aluminum look like god tier material |
Yeah exactly. The dealer on Ali told me about it after asking him |
Cheapest route possible |
Makes sense I guess |
Cheapest route that is also got the highest chance of success. |
Btw, Sand all the rust off before you try to remove the sideplate/install the new one, since your never gonna get the bearing past all that rust |
(iron oxide is larger then iron) |
Willllllll do champ |
First I'ma solder on some of these good connectors you recommend |
Nasty, I wonder how these would hold up on pure of road, so no road salt, but that crack '-' makes me second quess hub motors |
What kind of riding did that wheel see? |
Also, any idea what was the temperature when it happened? |
Sideplate failure is rather uncommon for hub motors... Generally caused by rough riding and/or absolute bottom tier hub motors.. |
I live and swear by bottom tier hub motors üòÖ |
But I guess if you have to buy another, maybe that 400-900€ hub motor isn't all that much more expensive |
I mean the seller did say a new side plate is $30, just annoying to wait for it to arrive and install |
And honestly, I bet the guy climbs curbs with his bike üòõ |
I wonder like, if you buy a bunch of hub motors on Alibaba, do you really get them for 80€ piece |
Curbs + bikes = broken shit |
Yeeah, I've ridden curbs my whole childhood |
Yea, when you where 100lbs lighter, and I bet it still fucked up your rims over time |
And riding on 16/20" rims |
Was featherweight, and I got a 26" really soon |
@Aramož hub motors are fine |
Sideplates are fine |
What *isn’t* fine is destroying the sideplate by yanking on it with a powerful mid drive motor |
^^ that yea lol |
Used a mid drive while hub motor wheel was on the dropouts |
Sad part is a side plate cost 1/4 of the motor price lol |
Ah, yea that will do it. |
Rather common for that to wreck shit, I assume the aluminum can't handle the fatigue cycles |
IIRC, fatigue life of aluminum is basically that light stress can be handled for extremely long periods, but higher stresses fatigue it much quicker, and the stress basically lowers the max strength of the material, so higher stresses also surpass the now falling strength much sooner |
So while it could handle pedaling stresses for a long ass time, mid drive stresses are just like.. game over |
Yeah makes sense , guess it's part due to it's porous and softer composition compared to most other metals used for similar applications |
Conspiracy theory: the above 2 accounts are the same person but they have 2 different personalities |
I knew it. |
So my tire lasted 600km |
u buying cheap ass tyres or something? |
370-380miles aint that much |
For tyre wear imo * |

Known to last up to 10,000 miles. |
this is my fav: |
It literally started melting the wire housing |
Uhhhhh , is it normal for my charger wire to get this hot ü•µ |
Now it's just a crumbly mess |
No, thats not normal at all. lol |
This is why we have fuses in the U.K. |
Why we have breakers |
Why we don't allow 18ga wiring in appliance cords (or at least, shouldn't...) |
Considering strands are snapping out, I wonder if thats CCA wiring? |
Hmm should I just replace the wire with my old bbshd battery wires ? |
Or just buy some appliance cord for 15 cents a foot? |
Or use an actual appliance cord off something else? |
with a plug already on it.. |
Good idea |
Like. Washer? |
A washer from the scrapyard |
An old electric kettle? |
Whatever. |
Nah won’t necessarily protect |
You don't have any luck lo, makes me feel like I didn't make the worst purchase possible |
hmm but charger seems defective if it melts input wire |
It was on an extension cord idk if that makes difference |
But anyways I cut the melted crumble part off and put it back together |
Currently charging my bike |
hmm weird that it heated that much |
I know , last few days when unplugging been noticing cord is hotter than usual |
Schwalbe Marathons. Is front hub bike. |
About the charger, I put my hand on the wire , after fixing it , I can feel the electricity flowing through it through the wire insulation , it felt kinda rough |
thats pvc insulation. theres diferent types of insulation |
Uh, there is no 260c PVC lol |
I don't even think the best silicone insulations are rated over 200C? |
260C is like, fiberglass style wire insulation temps. |
https://www.awcwire.com/customersupport/techinfo/insulation-materials PVC wire is rated to 105C. |
But IIRC softening occurs as low as 80~90C |
Another wire manufacture rates PVC at 80/90/105 depending on grade: <https://www.galaxywire.com/custom-wire-cable/jacket-insulation/pvc-polyvinyl-chloride/> |
i think its like a " well itll melt at 100, and lquidfy into napalm at 200, and combust at 260! |
Basically lol |
Affirmative! |
If only my butt was that...nevermind |
They might be referring to the short term short circuit rating |
XLPE for example can be rated for 250c short circuit, 150c continuous operating |
oh wtf. |
:monkeylookingaway: |
I honestly don't know what did it , I cut off the burnt crumble part of the cord and rewired it now it's never gotten as hot since |
