Ebikes, bicycles, scooters, skateboards, longboards, eboards, motorcycles, skates, unicycles: 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.

Weight limits for bicycles need to be higher and more transparent, especially if the majority of people want to use them.

i actually had trouble with that and found my only option being giant so far…

Also had weight issue converting bike into electric with custom lifepo battery, which ended up being almost 30kg alone. Rear wheel was shot after like 20kms. But the bike was so cheap it wasnt surprising.

Too bad i came across this bike after finishing the build, might've got it instead. https://youtu.be/QV88C5ZK0x0?si=C9Ik2iCy_xDxlNbb edit: look like you cant buy it anyway

This is why I'm so pro regulations - a simple (predetermined) fact sheet that every bike sold needs to disclose.

And as society and needs evolve keep the regulation alive and modify it accordingly.

Ofc the industry is gonna bitch about it like it's the end of bike industry for good & try to gift it, but after a year it will be normal, costs negligible, profits the same - but the market more transparent.

And for most things, like this bike thing, it can be super a simplistic requirement, no need to be to the kg exact, it could be defined by categories of 50kg even. However the weight class should mean under a certain higher-than-usual stress on the constriction (bikes mostly arent meant to be used stationary).

But yes, manufacturers should test their products to the breaking point, not let costumes do it (unless it's Bethesda, then it's just expected).

Also - I've recently helped a 130kg friend get an office chair, nothing too demanding I know, but I noticed how weight specs, if even provided, seemed a bit random. Even (separately provided) piston specs were different for what seemed the same model.

Weight limits on performance bikes are total nonsense. Probably are there just to comply some law. A pro enduro rider weighing 20kg less than me would destroy my setup any day.

I find hard to believe a traditional 26er with 36 triple cross spoked wheel from a reputable manufacturer can't hold up to any rider capable of moving on their own and sitting on a saddle any amount of time.

Unless they are heading to Whistler's a-line

Your MTB wheel set is tested on the standard it's meant for. There's really no reason to test downhill wheel set for maximum weight limit for commuting or road racing because it's not made for that purpose. It's a specialized product for niche sport.

[–] hawgietonight@lemmy.world 3 points 1 month ago (1 children)

Although true, it isn't the point I'm trying to get across. My view is that weight limits aren't a great metric. You don't have to go for niche sports, the traditional xc/trail bike is what everybody starts with on mtb.

Say this example xc bike has a weight limit of 150Kg. Rider A is at 170Kg buys this bike ignoring the limit and just rides smooth local fire roads for some excersise.

Rider B is young, athletic 70Kg build. Buys this SAME bike and goes on rides with friends that know all the fun trails. Rider B is getting faster and stronger, and the bike starts to show it's limitations.

It's clear which bike will fail sooner. Weight alone doesn't matter, and both riders are using the bike for it's intended and designed purpose.

Manufacturers cannot reliably slap a max weight to their bikes because of all the other factors involved. And if they do, it will be way conservative to avoid getting into legal trouble.

That's why the manufacturers clearly define what sort of abuse the component is expected to withstand.

For example, take a look on this document on DT Swiss wheels (took it as example because I recently bought DT wheel set and checked the manual)

What kind of bike is that in the pic?
(I dont know shit about bikes, but no amortisation, medium but flat tires, a handlebar that seems street sporty ... seems frankensteined)

[–] BruceTwarzen@lemm.ee 4 points 1 month ago

That's a gravel bike.
