and an offroad fun bike
A cargo bike, a touring bike (probably similar to what the ECR is now honestly), a roadbike with dropbars and a lightweight minimal e-setup, and a full suspension something. And a beater bike for not being paranoid about locking it up outside businesses for 20 minutes. :P
Haha
Beater bike is real
I need a beater bike. At some point in the next few months, I'm likely to just pick up a singlespeed something or other for short trips into town.
For acoustic riding?
or are you gonna be tempted
by voilamart
üëÄ
Nah, acoustic. A "It's snowing and the roads are salted and this bike will be fucked by spring, but that's whatever" bike. :P
haha
I still think a voilamart kit for like
<$120
could defo factor in
;)
If I were intending on long distances for it, for sure.
But on my first trip through this town to get a feel for it, I missed one cross street and ended up out of town on the other side.
I don't need assist for that. lol
hahahaha
you live in a tiny village
Basically. lol
@larossmann them grasping at straws
I have a cat
His name is mr. clinton
he would meow at UPP.
Yes, I have seen your cat
your cat is great
@Black Moons I think it was a genuine translation error tbh
But it‚Äôs nice that they at least agree a bridge rectifier is ok to use
they still don't understand how one works though
because even if he was using some kinda regulator (on an e-bike, what the $#@%$), the bridge still wouldn't let one battery charge the other.
I can only assume they confused 'rectifier' with 'current regulator'
So now UPP is claiming the diodes failed?
They are assuming that the rectifier shorted from overheating
it was heatsinked and mounted for airflow..
Twas the inrush current
The inrush current at the very end of the ride?
Ah right, forgot that's a reference now. lol
Ik but UPP think, probably due to a translation error, that you were using an underpowered bridge rectifier
Not inrush current, the outrush current
Yea I particularly enjoyed that comment
That person was so confidently wrong.
@larossmann Btw as I posted yesterday, its typical for a 50A diode to have crazy peak current specs, in the 500A+ range.
so even the rush from charging your controllers capacitors is of little consern
So yeah, no reason to think the setup failed even if it had exceeded the continuous spec.
(thats 500A for 16mS btw)
It‚Äôs mainly heat that kills the diodes according to the electronics discord so short bursts don‚Äôt matter
yep
they are such simple devices theres not much to go wrong till you physically melt the silicon inside
They still called it arduino engineering though lol but haven‚Äôt had a proper explanation why
@larossmann Heres a question for them:
Who called it arduino engineering lol
"EM3EV allows their batteries to be directly paralleled and their BMS protects them. What makes your batteries worse that you can't allow that?"
@district9prawn people in the electronics discord
Akbar: well considering EM3EV is even selling little half bridge boards lol (that MIGHT have some sync rectifier mosfets or something)
Yes the Chinese sellers even state 10mV delta balancing on those devices
There‚Äôs just very little info on them
@Black Moons maybe sabvoton ones but not phaserunner ones, they are so tiny
heheh.
@Akbar Im waiting for some nutjob to try and build a battery out of 100 of them.
(using one for each cell)
They have one type which can be chained
"for recharging, I just use this balance lead shows off 100 pin connector"
Which should allow as many packs as you want in parallel and balanced
heh
I'm buying some sabvotons
üëÄ
I want to buy a sur ron
Damn, that e-mail is so annoying. You can really see there's a comprehension gap there
when you peel the wrapper on your pcb cracker
what did that thing ever do to you.
It probably broke before teardown, rip eggrider
Is this fixable?
It just popped off
wait what
got any more pics?
When i get back home. The derailer came off the hanger. A spring also came off the same joint
It won't stay on so i think a part is missing
That's a first for me.
If you don't get any good answers here, I recommend also posting to reddit on r/bikewrench. These sort of questions generally get at least a few knowledgeable answers over there.
Is that a subreddit I can get banned from
Doubt it. You'll likely get people questioning your ideas, but you'll also get people trying to answer your questions.
Hopefully.... :P
There's still a lot of bike culture over there, but they're a lot less snobbish/purist since it's a subreddit built on the foundation of actually helping people figure out their mechanical issues, no matter the bike.

@DeerüÖ±oi Looks like your missing a snapring and potentially the spring itself
the snapring is an off the shelf part, the spring,, not so much (unless its still attached to the derailer)
Auto parts store should have some snaprings to replace it. trick will be figuring out if its metric or standard (I think it would be metric but.. never know)
F @Akbar
There‚Äôs blue slime in the tire which is preventing the patch from sticking
Yea we are not a fan of slime..
We are however fans of armored tires
and armored tire inserts
I got a pinch flat from a massive pot hole
Ouch.
oof
why is there slim if the tire isnt tubeless?
slime*
Idk I think it‚Äôs supposed to self seal for small punctures
Yea
