ive seen so many horror stories with the dual rear shocks |
single rear shock |
larger battery compartment |
actual welded tube frame |
with sheet metal welded for enclosing |
field weakening kicks in on x1 pro at 10k rpm but is only rated for 12k |
so stupid |
people are getting it to almost 14k though |
:FireDuck: |
@EPHIIOS |
Oof |
Holy cracked cells batman. |
Wonder why they cracked... Least they didn't burn |
I'm more worried about the rust on the "nickel" @Black Moons |
@Rad Not sure if rust, or cell goo. Do cell tops usally rust? |
Bosch is officially on my no go list either way |
@Rad I can think of much better reasons to never use bosch, but sure. lets go with that. |
I mean, Bosch was already on my no-go list for entirely unrelated reasons. Too much history of proprietary locked-down nonsense. |
But yeah, I'm not sure that's rust. Seems more likely it's cell goop and corrosion from that. |
I also wonder if the cracked cells couldn't be from impact. |
Ok the serialized parts is another reason |
TBF, Im amazed it didn't go up in smoke |
Like, 2 cracked cells, what? |
something went *horribly* wrong in that packs life, and I don't think assembly was to blame, unless somehow their method of adding strips put immense stress on the cells? |
I'm glad it didn't catch fire |
Especially considering the bad cells still have voltage. |
I wonder what the BMS thought of all of that. |
bosch isn't known for its 'high power' either, so I kinda doubt they where discharged too quickly/overheated. |
I bet they are high ESR as hell |
ESR? |
equivilent series resistance |
Yeah that didn't clear it up |
I'm just a big dummy |
Cracked cell is reading 47.5mOhm in the picture, and 3.74v |
Apparently 40mOhm is typical for the LG MJ1? Unless I'm misreading the datasheet. |
Weird. |
Cell has a big ol' crack in the side and is probably leaking goop everywhere, and it's like "Nah I'm fine." |
Also, are those the balance wires?! |
I guess |
Ever since joining that facebook group I've had nightmares |
Who... uses yellow/brown for balance wires.. and pretins the wire and hardly.. solders to the pad? |
Thinking of leaving it |
the brown wire shows damage to the insulation too.. |
There's more shit like that on there |
I feel that pack is sus as hell |
I can't imagine bosch doing that shit for balance wires |
Yeah, it's weird how everything looks precision machine-assembled except the balance wires, which are just kinda... *there.* Like an afterthought. |
Interesting that the seperators are designed for the balance wires though... |
True |
I wonder if it could be a rebuilt pack?... that or impact.. |
I mean, how do 2 cells blow? |
.. crack |

yea that picture sums it up |
And yaknow, because his fork wasn't wide enough, he just welded the back end from another bike onto the front end of that bike |

I'd rather be shot |
I like the lack of front (rear?) brakes. |
you think he could have at least left that shit on when chopping the frame but nah, its fine |
Being shot is a quicker death |
So my hands were getting super fatigued with throttle riding a thumb throttle. I popped it open and uh… loosened the spring a bit. Now it’s significantly easier to maintain power levels for long periods. Just… now I can accidentally wiggle the throttle into sending power. Oops |
was it a universal thumb throttle |
those suck fr |
i almost never use them |
i think for constant throttling twist is still best |
Half-twist is my favorite, but I don't do much constant throttling. |
Also cruise control is a thing |
Don't use cruise control unless you have e-brakes setup though. |
you really want the controller to know your going 'OH SHIT' and stop applying power. Especially if its a mid drive. |
Even a hub motor can significantly extend your braking distance if it's fighting you. But yeah |
(that said, its freaken amazing using cruise control on a mid drive on mild offroad trails, just hearing the motor get slightly louder on hills but the pitch not change at ALL) |
just HILLMURDER. |
ez just pratice emergency falling off |
I just wish I could tell the CA that I want cruise control to set *speed* instead of power (for current-mode or torque-mode controllers). If I'm cruising at 15mph and reach a hill, I want to stay at 15mph, not at 250w or whatever. |
Not a huge issue, since I do most of my cruising at the max speed cutoffs I set in the CA, but still. |
@NCC1941 Interesting, I assumed that'd be the default behavior but I guess its cause I have a speed mode controller. (that or maybe Iv only tested my controllers cruise control and not C/A's |
Yeah, most likely due to speed-mode controller. All the CA's cruise control does is lock the throttle output voltage. |
Lame. |
Wish I had enough people on my patreon that I could start work on a replacement for the C/A... |
Especially since iv already done microcontroller programming, electronics, etc... |
Yo what?? |
@NCC1941 *drools* I just had an idea.. for the most epic C/A feature ever |
You know how gyros are pretty cheap now right? |
those mems units your cellphones use... |
Auto-off gyro controlled turn signals. |
*Take my money.* |
I mean, I'm broke right now. But in concept, *take my money.* lol |
Hehe. |
Like imagine that, turn signals that actually detect that you turned |
Especially if you stick it on the handlebars, it should be able to detect even lane changes |
And you could have something like a momentary center return button, and just press either direction for 1+ second for 'off' if it ever screws up |
(or another button) |
See if I made a C/A, id throw some power outputs on it too. |
That's a you issue |
For turn signals/brake light/headlight |
I just have my mf switch set to toggle speeds so I can cruise at that |
And it will dynamically adjust power based on throttle curve you were on when you triggered it |
That's why a thumb throttle is great since you can finely select a throttle level consistently . |
If I throttle at absolute minimum I can get like 150-200w CC |
That is on almost no level a 'me' issue. lol |
