Brakes too. EVs use regenerative braking for most deceleration so brake pads/rotors last forever. I commented earlier in the thread that my youngest brother has both an EV (Rivian R1) and IC (Ford Bronco). He road trips both and tracks costs and its pretty amazing how much cheaper the EV is...

Orange County seems pretty serious about it, they even charged the parents of a 13 year old who died riding his surron clone. Which seems harsh (hes dead, unless they are utter psychopaths they definitely regret giving it to him) but also giving a 13 year old a 12kw emoto that goes over 50mph...

Bike hardware is almost entirely metric, even in the US. I assume its just because bikes historically were made in Europe so European sizing mostly drove the bus for standards. But there are weird exceptions. Pedal wrenches are generally 9/16". Bike chains are 1/2" pitch. Handlebar clamps...

Way back when I used to commute on a fixie, the cheap bolt on hubs my older bike had used 15mm nuts. Super common on bolt on track hubs in the US and Japan. I kept a shorty 15mm wrench from Sears in my saddlebag as a solution. Eventually put Phil Wood hubs on that bike which used an allen...

As a pro architect and hobby woodworker, I prefer imperial units. Aside from just being used to them, base 12 divides in half, thirds and quarters evenly, which are extremely common operations in design at both building and furniture scales. Base 10 divides in half and fifths and thats it...

There is tons of eco-fashion that doesn't really do much aside from making people feel good. Like, tearing down a house to build a new one is likely a net negative no matter how green the new house is, since building materials are pretty carbon intensive to manufacture and transport...

The main issue with the way media covers things like climate change is they absolutely love to frame everything in horse race terms, because conflict keeps people engaged. So when you have an issue like climate change where the educated consensus is overwhelmingly on one side, they will find...

My younger brother likes to road trip and has both a Rivian R1 and a Ford Bronco. Even on longer trips he prefers the Rivian, and his experience is charging is largely a non issue. Stop every few hours for 25 minutes or so and then back on the road. Even on trips where he is crossing several...

Right, power (watts) is volts times amps. Amperage determines your wiring requirements, so if you want to transmit over long distances you increase voltage to decrease amps. A lot of small solar installs (like RVs or off grid cabins) just keep everything DC because thats what solar panels...

Low voltage DC transmission (like RVs use) does require large wires, but fortunately thats not how anyone transports electricity over long distances. They invert DC to AC and step up voltage so that you're transmitting higher voltage but lower amperage. The transmission issue isn't that its...

Been 3d printing for a while now. I use it for a lot of purposes, but primarily its great for shop organization and woodworking jigs. Need a weird router jig for a specific task? Super easy to knock up a model and print it. Vacuum adapter for a tool with a weird inlet size? Trivial to model...

Especially since despite their grandiose claims, there is some evidence that their hypersonics don't live up to the hype. Shocker, I know. Russia has launched a handful over the course of the war and analysis has been.. mixed. Patriot has shot down a few, or at least so its claimed. If...

It is true that being somewhat in the lane is safer, unless the lane is super wide or there is a generous shoulder. The reality is that most people aren't psychos who will try and kill you, but a lot of people will do incredibly stupid s*it that will endanger you if they think they can get away...

I think I'll take the crime rate and justice system here in the US to the one in Russia. But you do you. Lol. Ok. You're probably right that his regime hasn't been seriously damaged, but thats mainly because hes a dictator who is largely insulated from any consequences. But even dictators...

If Putin thought using nukes would have won him his special military operation, he would have used them years ago. Not losing the war he started is basically life or death for him; its hard to imagine a dictator surviving that sort of humiliation. He hasn't because a: he knows it would mean...

So more classes, with presumably a lower bottom end for kids and a much higher power limit at the top (750w is the current limit, so 2000-3000w is 2.5-4 times the current legal limit) and no speed cutoffs. A 2000w bike with no limit is going to be pretty easily capable of 40mph (just quick...

I'm unclear what you are proposing. If you had your way, how would ebikes be legally defined? The rest of the world regulates ebikes AFIAK. In most cases, more stringently than the US does. I don't really see a point in engaging with the "why is this sold as a safety issue" because I...

By access I mean everything that isn't strictly motor vehicle infrastructure. So bike lanes, MUPs, paths/sidewalks, unpaved trails, singletrack, etc. I don't mean strictly singletrack. And hey, if all you care about is riding on the roads, you already have an option (legit motorcycles) that...

Can you point at someone making the claim that power limits/assist cutoffs/whatever are primarily a safety measure? They are almost entirely an access measure, because at their core, ebikes are motorcycles. They have two wheels and a motor, and most non-powered user groups are not interested...

On roads, maybe, but on trails and such it happens all the time. National Wilderness still bans all bikes, and MTBers lose access to trail pretty regularly when land is put under wilderness protection (which is frustrating because MTB advocates have been put in the position of having to fight...
