Ebikes, bicycles, scooters, skateboards, longboards, eboards, motorcycles, skates, unicycles, heelies, or an office chair: Whatever floats your goat, this is all things micromobility!
"Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city.
micromobility is seen as a potential solution to moving people more efficiently around cities"

It's a little sad that we need to actually say this, but:
Don't be an asshole or you will be permanently banned.
Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.
Focus on discussing the idea, not attacking the person.

"...a US patent application from SRAM shows a radically different chain design.
<...>
A conventional chain is made of a pin, roller and a set of alternating inner and outer plates. SRAM's patent removes the need for inner and outer plates with the stepped design acting as both."
The picture almost looks like it does not have pins as well or maybe more like they are in line. Not sure what the thing marked 50 is. My biggest question is does it have any advantages or disadvantages. Its like is there a point to the change outside of maybe cheaper manufacturing (less individual parts)
Presumably there's the small benefit of not having to remove two links at a time, since there's no longer a distinction between a link with outer vs inner plates.
I do wonder how this affects coupling (aka master) links.
