tyty |
have pics if youd like them |
yes please |
eh, 5/32 5/8 same thing |
awesome, thank you |
npnp |
comes with 4 hoseclamps per pair btw |
what are the hoseclamps for? |
sorry, i'm a total newbie |
the torque arms don't attach anywhere to the frame directly, so hoseclamps are used to attach the four slotted arm to one of the arms of the dropouts |
do you have a picture? |
havent installed on my bike yet since i dont have the wheel yet |
basically, if the hub decides it wants to rotate, it will have to either deform or pull the torque arm down with it, which takes alot of force if you have a good torque arm |
takes very little force on a normal frame without torque arms because the dropouts of a bike frame were never designed to have motors mounted onto them |
(thin tube aluminum VS 5/32 or 1/4ths steel |
2 is enough |
4 is overkill |
ohhhhh |
that makes sense |
ty, i get it now |
np! |
4 per side or four total? |
will it still work if i have a horizontal dropout? |
4 total |
Yeah, i think so. Torque arms effectively take the dropouts out of consideration entirely |
akbar technically has 3 cause he used one as a spacer |
and that 3rd one handles his regen |
but my 2 are secure enough to handle regen aswell |
i remember we had concerns about he 5/32 steel being too thin in a one per side of the motor configuration |
compared to 1/4ths steel |
you need arms going in the opposite direction for regen dont you? since the torque inverts into a direction the torque arms aren't protecting from? |
How do I adjust the chain tension then? |
i would assume your derailleur handles tension doesnt it? |
I'm doing a single speed build |
ah |
torque arms are only restraining the hub motor rotationally, you should be able to set the tension to the right spot then install the torque arms |
but dont take my word as i am not a bike tech and dont even have my own yet |
As in, find the right spot for the wheel, then attach the arms? |
afaik yes |
Dw haha |
Okay cool |
Ty |
the arms can be installed onto the shaft then hoseclamped indefinately later |
Ah right |
double triple quadruple quater pounder bob is a ripoff |
just use electrical tape |
Hailongs are made of pot metal and crap, mine broke after one crash |
i crashed with my ebike and my battery is fine üòõ mines a rention |
Imagine having so much leg power you completely rip apart your derailleur attachment (joking btw the chain got jammed) |
Wow the chain had a master link, hoohoo, at least I can roll it now with chain removed |
If I could somehow break this chain smaller I could run it with no rear derailleur |
Gotta love having zero tools |
I’ve ripped mine off before |
This is called a derailleur hanger |
every frame has a special one just for that frame |
Good luck to the airbnb host that let me borrow the bike, yikes. I noticed it was a pretty specific shape bolted into the frame |
Another reason to adjust your derailleurs accordingly... and why I love not having a chain at all... (though single speed motorbike i guess wouldn't deal with that issue) |
i would enjoy just having pegs and no pedals but pesky laws say that the pedals must be operational |
just do a left hand drive |
Just pull a past-me and have a single speed setup and only pedal when it's even slightly helpful :think: |
so u got the right drive train ss setup, and left side would have a straight chain drive |
prob solved |
üòõ |
Dual chain should be more common for ebikes in my point of view as a motorcycle builder and bicycle rider |
@Trenavix Left-hand drive used to have some development |
for engine bikes |
ya left side to a 6 bolt sprocket, right side for pedal powah |
but it's generally an awkward setup |
there's a reason it never made the jump to eBikes |
Firstly, because most eBikes use hub motors |
Sacrifice your rear brake for regen and no dependency on the main chain. Solves lots of issues |
Secondly, because low power mid drives don't mind being on the pedal drivetrain |
Ah yeah I mean if it's hub I have no issue. But I mean mid drive setups |
and in fact, gain an efficiency benefit for doig so |
doing* |
Your typical Bosch setup with a belt or chain is just fine |
it's intuitive, it's good |
u can still have a rotor on a left had sprocket setup. jut gotta have the right spacing |
Nobody using a Bosch/Shimano/Brose prebuilt would *want* a left hand drive |
It's counterintuitive to the pedal-focused eBikes |
So you're advocating for it |
for a niche of a niche of niche |
Which I get |
But it's just not big enough of a market to be popular |
I myself just hate derailleurs and always have. Never have had a mid drive but man imagine having a bad derailleur on top of managing actual power, I'd probably hate it |
Mid drive on moto I'll eventually do but ebike nah |
well my middy is gonna be SS and still a "bike" |
at least until i can get a moto wheelset for a left hand sprocket kit to be usuable at that power levels |
@Trenavix Derailleurs are fine |
You have a certain perspective because you operate in a certain way |
Derailleurs are miraculously efficient |
and good at what they do |
Obviously if you're saying "I want something 16kw+" |
you wouldn't use a derailleur |
but that's tantamount to saying "I want a motorcycle that isn't legislated like a motorcycle" |
in the context of eBikes |
it's totally different |
Nah I mean even on bicycles, I hate derailleurs, just because all the ones I've had always get misaligned very frequently |
