[meme] Trains -- not driverless cars -- are the future of transportation

Reply in thread

I live in the middle of nowhere and drive race cars on the weekend, I think we agree on a lot of things. I love having plenty of space, not a fan of close neighbors, apartment living or any of that shit.

I still want cheap trains and micromobility though. Every once in awhile I need to go into the city and taking my ebike in on the train is so much better than driving. Also even if you still drive like normal, it would go so much smoother if all the city folks stuck to the train and got off the roads.

Not saying cars should be more expensive, and definitely not saying city living is the way, but having better options for city folks only helps the situation for the rest of us.

Can someone advise me re: delta 9?

Delta 9 is just THC. Cannabidiol is just CBD. Delta 8 and Delta 10 are the strange ones made from CBD which get you high but less so than delta 9. Sounds like a THC cookie to me and would probably have an effect. Interesting that CBD didn't work for you, but the Cannabidiol vapes did as those should in theory be the same ingredient.

New E-Bike Crankset Is A Chainless Pedal-By-Wire System That Incorporates Regenerative Braking - CleanTechnica

Reply in thread

You're right, but I think there are some other benefits to doing away with the chain. I have an E-mountain bike and between chain stretch, chain damage, and mud I go through 2 chains per season plus a couple trail-side repairs. Also, no chain means you can optimize pedal speed/torque for each individual rider, and keep it in the ideal range all the time regardless of bike speed. Essentially it offers a much wider power band than gears and a chain. You could also optimize crank length for clearance instead of torque. The front chainring is also a big point of contact on mountain bikes, removing that could improve clearance with the right design. I'd also be interested in the regenerative braking - if I go on an Enduro ride I'm cooking my brakes on much of the downhill, regen could save those and recharge the battery at the same time. Maybe regen could even lead to a smaller battery and save some weight.

Sure there are disadvantages - weight, complexity, efficiency, probably others too. I think with time those will improve though and this just might be a viable setup for certain use cases.

Cycling Fallacies - Counters to Common Anti-Cycling Arguments

Good resource thanks for posting! It seems like they really went out of their way to avoid mentioning EBikes. My experience has been that for folks with disabilities EBikes are a game changer as they allow people to put in as much effort as comfortable but not go past that. I also think the section about it getting sweaty could have mentioned EBikes as a potential solution. I understand they don't want to piss off cycling purists, but I think it's important to recognize the positive impacts these new technologies have.

Finally, I get their stance on helmets and agree that helmet mandates aren't ideal. That said, I think it's disengenuous to say that helmets are useless. It's true that those studies looking at city helmet use found no difference in safety overall, but I'm not convinced that wearing a helmet wouldn't improve my personal safety. I've absolutely wrecked a helmet riding on the street, and I'm very glad it wasn't my head instead.

[meme] Trains -- not driverless cars -- are the future of transportation

This is key. Urban planners and environment folks focus so much on their respective fields and don't consider dignity enough. Of course we'd all like cheap, fast, sustainable transportation, but not if that means being packed into bench seating, plagued with delays, and sometimes even risk our safety due to other passengers. Trains don't have to be bad, but the penny-pinching planners often ruin the experience.

35MPH Long Range Ebike?

Reply in thread

Really appreciate your thorough answer! I'll definitely think about an electric motorcycle. IMO if I'm going to go through licensing, I might as well get something that goes full car speed.

I think you're right that battery capacity would be the biggest issue building out an ebike. That said, a big frame triangle can fit a lot of cells. Something like 3000Wh could probably get the job done. If I could get the bike aerodynamic enough to cruise on a 750w motor, then max range would be 3000/750=4 hours or 140 miles. Obviously won't hit that in real world conditions, but 70 would be possible.

I terms of legality and ethics, I totally agree about treating cyclists and pedestrians with respect - on my current ebike I keep it under 18MPH on bike paths and slow to pass others at a safe speed. My vision for this bike is more rural back roads near my house which are mostly empty but have an occasional car passing by. I'm not a big fan of laws generally. On that front I'll probably run a cracked controller with a toggle so if I get pulled over I can put it back in legal mode with a keypad sequence. Slap some aliexpress "250 watt" and "class 2" stickers on it and trust that the local cops are few and otherwise occupied. Where I live folks rip illegal dirt bikes and ATVs on public roads with impunity so I can't imagine this being a big problem.

F2 and F3 regulations updated with gender-neutral language, new red flag rules

Reply in thread

I'd argue it shouldn't matter what the cause is. It's a little far fetched, but I could imagine teams organizing mechanical failures to gain an unfair advantage. All it would take is to tell the driver the wrong gearbox mode to cause a spin, Monaco style. As written it would suck to have an honest car failure and then lose extra grid places, but I think those kind of incidents will be pretty equally spread among the field.

35MPH Long Range Ebike?

Reply in thread

You're not wrong but public transit here sucks. Every weekend I go to a friend's house - by car it is 1 hour every time. By train it is somewhere between 2.5 and 3 hours depending on delays. Public transport (even when poorly implemented) offers a great way to get in/out of medium to large cities, but isn't really ideal for trips from one rural area outside the city to another. What would be much more convenient would be if I could bring an ebike on the train with me. Most of the distance on this trip is covered by a 1h train ride, and it's just the busses on either end which are slow and unreliable. Unfortunately they don't allow electric bikes at all, and normal bikes are only allowed during certain hours.
