Hi gang!

[PedalUma]

Watch your dropouts. Use anti-turn washers with torque arms. You may still have frame failure. The twisting force in the frame's dropouts is way beyond limitations. Generally stay far away from hub-drives. What is cool about torque sensors is that you push your foot to go, instead of using a thumb or twist pressure you use foot pressure.

Watch your dropouts. Use anti-turn washers with torque arms.

My motors currently have torque washers, but no torque arms because the axle only gets torqued one way and gets jammed in the dropouts.

Regenerating hub motors need torque arms because the axle gets slammed both ways which eventually loosens up the axle nuts, then your nuts fall off.

You may still have frame failure. The twisting force in the frame's dropouts is way beyond limitations.

The twisting force on the axle is related directly to the torque of the motor (plus the measly bit the human adds) and there's A LOT More torque per Watt being doled out by a mid drive motor.

Generally stay far away from hub-drives.

I like my hub drive for its simplicity and easy maintenance.
I don't have and mountains to climb, so I have no need for a mid-drive.

Voltbike also sells the Enduro,..

It's essentially the same ebike that I have with a mid-drive for only $400 more.

The 500 Watt motor has WAY more torque than my 500 Watt hub motor and would stress the dropouts more.

And I simply don't want a mid-drive ebike!!

I don't want to have to pedal, and you have to on a mid-drive or you'll tear up your driveline and stress the hell out of your motor.

A hub-drive isn't something that is just "good enough" for me, I prefer it.

I would have paid $400 more for the hub drive.

What is cool about torque sensors is that you push your foot to go, instead of using a thumb or twist pressure you use foot pressure.

What's cool about not pedaling is that I need no sensors at all, except my Hal sensor throttle.

I didn't bother connecting the PAS sensor when I installed a KT controller and display on my Et.Cycle, and I turn it off when I ride my Outback.

If I had a torque sensor, I'd attach it to my handlebars and use it as a throttle to control my ebike.
(Apparently that has been done.)



I never wanted an electric bike.
I wanted a street legal Enduro style motorcycle like the Honda XR200R that I had in 1984, but a motorcycle costs 3-10 times as much, plus at least $1200 a year for insurance.

Plus licensing, fuel, riding gear, maintenance, speeding and trespassing tickets.

And I wouldn't feel comfortable riding no-hands knowing that I'm risking an Expensive dangerous driving fine.

I'm OK with only being allowed to go 20 mph.
I have fun, I get off my ass and outta the house, but unfortunately it is more addictive than smoking Vados.

I spent ~$3000 in 6-7 years growing my own Vado. I remember spending $69 for three Saltwater OG Kush seeds that all died.

But I've only been in the ebike game for 2 years and 3 months and have spent over $9000 CAD on my e-bikes and all the fun stuff to go along with it.

My only worse addiction is my smoking , but I but native cigarettes and only spend a few hundred dollars a year.

I wonder what's going to kill me first?
My smoking, or my ebike?

Probably both, because I smoke while I'm riding, and when I light my cigarettes I take both hands off the handlebars and both eyes off the road.

Something is bound to go wrong, but I'm pretty good at crashing too.
Even better than Stephan.

I was wondering about that too, but in his defense, derailleur is a Sucky Word, and they spell it wrong !!

I don't care if the French invented it, the English version should simply be called a derailer.

So, in protest, even though I'm a Canadian that is supposed to be bilingual, I'm adding DR to my list as well as derailer.

After all, it's just a simple mechanism that derails the chain from one toothed cog to the next.

All my derailleurs are built in China anyway.

When I road raced it was just called a 'mech' or 'rear mech' and the accompanying cassette was just the 'block'. As in "swapping out a block"

We just called them sprockets as kids. Front and back sprockets big ones and small ones.
The smaller ones on the back were for going faster and the smaller ones on the front were for going slower.

I remember being confused by that.
It didn't seem to make sense, so I turned the bike upside down and watched how the different sprockets made the wheel turn at different speeds. That helped me make sense of it.

I remember one kid that thought he had a 7-speed bike because he had 2 sprockets on the front, and 5 on the back.
I told him it's 2×5, not 2+5 and counted out the gears for him as I turned the crank through all the gears.

I don't remember what we called the derailleur? Probably just called it the gear changer?

Hi gang, I wasn’t sure where to put the following observations, so I figured I’d just add to my intro post here where I first brought up the lingo issue...

1. The section that is divided into all brands/makers seems both difficult to keep current and also seems to be not universally used. People frequently post brand-specific comments/questions in more general sections. I’m not sure what to propose, but I think this isn’t quite working as it was meant to.

2. I posted an issue/question about the forum software “to the top of thread” feature in a section that I thought would get attention from the administrators/moderators here but I got no response. There ought to be a forum or email address for having those conversations with the management of the site.

3. Below is my list of acronyms / terms / phrases that I wish were defined somewhere. Search and context are insufficient (IMO) to resolve this and it’s annoying (to me) that there’s no place to look them up:

PAS (pedal assist?)
BBSxxx (HD, 02, 02B…) I think this is Bafang-related and it refers to controller(s).
DR (derailleur?)
IGH (internally geared hub)
GVT Bafang’s “gear variable transmission” which is an IGH
Ghost pedaling… I don’t know what this means.
LFP ??
RTV (room temperature vulcanizing) describes a type of sealant for waterproofing.
SL (super lightweight)?
LBS- Local bike shop
MUT- multi use trails (bikes, walkers, dogs, children)
MUP- Multi use paths. see MUT
Analog — unassisted
eMTB- electric mountain bike
“H" as in "32h" for the wheel rim number of holes for spokes.
"T" as in "44T" is a number of teeth in the chainring or the cassette sprocket.
FS is for "full suspension".
<nn>S<nn>P - battery configuration for # of cells in series and parallel. Based on the individual lithium cells, these <nn> numbers determine a pack's voltage (S) and overall power (P)

You pick up the lingo after awhile here.
You've got most of them right.
"Ghost pedaling" means to spin the crank with little or no pedal pressure while allowing the cadence sensor to activate the motor. Makes it look like you're pedaling the bike.
"Analog" is a term used locally along with "acoustic" for a conventional, non e-bike.

Agree, it'd be nice to have a pinned glossary of widely accepted terms.

But lots of impracticalities here. I've written glossaries before (not about ebiking), and doing it right takes a lot of work and decision-making. Who would take that on? Who would maintain it? How would you decide what terms to include? How many visitors would ever see it? And who would abide by it?

Take DR for derailleur. In my 2.5 yrs here, I've seen it from only one member in one thread. Never caught on. Putting it in a glossary would imply a level of acceptance it never achieved.

And how to handle terms like PAS with conflicting usages? PAS was originally an acronym for "pedal assist system" — a useful generic term encompassing cadence-, torque-, and power-sensing schemes. If it were up to me, it'd still mean that, cuz we still need a generic term. But over time, it also became synonymous with cadence-sensing assist. Include both meanings in the glossary?

At another forum where I was a moderator I took on that task. I kept it in alphabetical order with whatever definitions were applicable. Multiple/conflicting definitions would be noted.

Yeah, it has to be curated and maintained, and it won’t work if it’s just users posting in a thread. An admin/moderator would have to maintain it and keep it locked. Or it could be open for posts, but then the definitions should be collected in the first post and then the contribution posts deleted. Anyway, just my take, Jeremy.

Some good approaches there! If someone took charge of the glossary, I'd be willing to help as a consultant and spotter (for new terms to consider). I'm sure others would as well.

I see that the main forum menu has a pinned category for rules and etiquette. Maybe add a pinned, locked glossary there if admin's willing to get involved?

Oh, here is one, Class 1, 2, and 3 in the bike world can have two very different applications and meanings in context. It can refer the type of bike lane, such as a bikeway which is physically separated from cars is Class 1. Or it can mean the type of electric bike such as throttle bikes are Class 2. The best is when you mix them in a sentence: Some Class 1's allow Class 2's but not Class 3's, but all Class 1's can ride Class 1's, 2's and 3's.
