and i think you don’t quite understand the dynamics of energy supply and demand. you don’t need weeks of battery for a solar plant in a sunny place. you only need enough to store the excess daytime peak, which mostly gets used up in the evening as the sun goes down and people get home. evening...

rea read what he said. solar PLUS battery backup. the grid doesn’t give a s*it whether the electrons are pushed by a dynamo or the sun or a battery, it just cares when and how much. california and texas have significant quantities of these plants, with the largest around a gigawatt plus...

not sure how effective this will be, but probably a good thing to have less cheaply made and badly supported batteries out there https://localnewsmatters.org/2026/06/09/sf-lithium-ion-battery-ban-advances/ I wonder what certifications they’ll use, and how they’ll prevent foreign shippers (or...

they listen and read, without independent thought or analysis, media which has a vested interest in maintaining the status quo. lies, partial truths, and exaggerations play into their identity politics and they genuinely believe the s*it they’re being shoveled tastes good and is nutritious.

haven't done one of these rides outside the city in quite a while. it was really nice to get out there, even if i a little bittersweet that i used to do these roads faster and without a motor :D the route. about 48 miles and 4,000 feet. it was a calm, perfect morning, warm in the sun and a...

not very often. takes around 300w to go 20mph on a typical large, heavy, flat bar, big tire class 3 ebike. say the rider provides 100, motor needs 200, battery needs 250. 500wh battery would last 2 hours, 40 miles of range. takes 650w to go 28mph. same 100 from the rider, 550w from the motor...

few if any roadies riding like d-bags on the west coast. the majority of the dangerous and entitled behavior comes from those in automobiles, as do just about all the killings of pedestrians or cyclists.

super easy. random brand with generic clik head. pair with dynaplug capsule. might take one minute from stopping with a puncture through jabbing the plug in, pulling the capsule tool out, popping the pump on the clik valve and reinflating. i’ve never had a ride ending tubeless puncture but...

Hmmmm. What happens when you plug the batteries in to charge? I never us my RE but if i recall the charger communicates with it?

yes, agree. i don’t understand how you can make and sell an entire e bike for that kind of money. a good pair of cycling shoes cost more 😂

california does not tax social security benefits. try zero percent. lots of people i know own rivians, both the SUV and truck types.

arguably less, since cyclists have a right to be on the road in most cases, and i’m not sure anyone has a legal right to the check out line at walmart. it’s all part of the same spectrum of behavior exhibited above - make fun of people for their clothing (in most cases highly functional)...

totally seamless, press the brakes a little and you see the power use go to negative, a little harder it goes more negative, harder still it doesn’t go any further but you stop much faster. on many EVs there’s also a steering wheel paddle that trigger full regen braking. i actually use that a...

in practice you rarely need to brake from speed when the battery is full, because you used energy getting up to that speed and staying there. the issue is more that the battery can’t be recharged at the same speed as it can be discharged, so it takes more than one speed up -> slow down cycle for...

yeah, it’s worked very, very well! i’m worried about cars, not bikes!

that's a good deal. i don't like the new one (bigger and heavier for not much benefit) so i might pick up a second 515. mine has around 1,000 hours of use, at least 200 charge cycles, so i figure i got my money's worth. it still works very well but the battery life doesn't seem nearly as long...

but, but, but, dr currie!

the first column is the percentile rank of athletes on cyclinganalytics - so if you read across from 90% basically 10% of athletes on that site can sustain 627 watts for a minute. so really we’re probably talking about 1 to 5% of the population, because anyone using a power meter and uploading...

absolute nonsense, and e-bike advocates need to stop using falsehoods to make their case. it takes over 600 watts to go 30mph on level ground on a decent road bicycle. check the CAT charts for RACERS and you’ll see that this is sustainable for about a minute for a 75% category racer. for an...

it’s not the majority - it’s the combination of a very vocal and manipulative minority with a good subset of the easily manipulated. he and his gang of _________ are historically unpopular.
