Can e-bikes revolutionise long-distance commuting?

It's still very dangerous to bike in Silicon Valley. Cars are generally bike-hostile and sharing the roads with them is dangerous. Not only that, but bike lanes are often just a symbol painted on the road. We need infrastructure that separates bikers from the cars.
Also, people just simply need to stop driving so dangerously.
The entire basis of city planning in the US has been based on cars for the last 60+ years. I don't see that changing anytime soon, unfortunately.
Cars are also designed (except for hybrids and maybe some electrics) to have jackrabbit-starts which make it intolerable at high speeds. You don't realize this until you drive a hybrid or electric, but it affects your attitude towards not only other cars but bikes and pedestrians as well.
SUVs have specific problems with their high center of gravity and visibility. I used to joke to my friends that, while renting an SUV for a week, I got flipped off about 3 times. Never happened with other rentals or my daily.
Ideally like http://s3.amazonaws.com/lcc_production_bucket/files/8920/in_... but in many places they're more like http://ichef-1.bbci.co.uk/news/304/media/images/48375000/jpg...
That second shot shows nicely why that particular solution doesn't work; cyclists take to the sidewalk as the road is too crowded and dangerous.
How much does this depend on where you are in SV?
When I lived and worked in Cupertino, for instance, my job was in a small office park on De Anza near Bollinger. My apartment was near Homestead and Stelling. The layout of Cupertino was basically mostly residential neighborhoods on roughly a grid, with islands of office parks and strip malls, except for a few main streets like De Anza and Stevens Creek that had mostly businesses.
It was pretty easy to bike in such a way as to have most of the trip be on the residential streets, which were generally pretty low traffic, and since things were mostly on a grid that didn't add distance.
That was 25 years ago, but looking at aerial/satellite maps of today's Cupertino, it looks like it is still basically the same.
Ideally, the law would set that speed limit to ~20mph since that is what a person pedaling can readily achieve.
The entire thing is pretty much exactly as the title is asking, though perhaps a little less glorious than "revolutionizing", and more just talking about the practical concerns of more people using e-bikes and how governments are responding.
To weigh in, I think it's a cool initiative with a lot of questions to consider, since I'd largely agree that an electric vehicle is probably a hazard to those with non-electric transportation. Though, at least in the US, I can't imagine normal traffic responding well to the inclusion of e-bikes, even if it would solve transportation needs for a lot of people. I am curious how the insurance looks for it as many years back (8ish maybe?) I looked into getting an e-bike but the insurance increase was prohibitively much.
Except he's not replacing a car in the car lane. He's replacing a bike in the bike lane. I maintain my title-article mismatch opinion.
My cycle to work this morning had a top speed of 40kmph (24mph). I was feeling particularly slow this morning and am only just getting back into cycling. I expect that soon I'll be quite a bit faster.
But you highlight the issue nicely; bikes are not self-powered, it depends on the human. Even with e-bikes this is true, most of them will only support the rider and have been made not to power the bike all by itself. So how to regulate that? Perhaps a good old speed limit is all that is really needed.
If you want to bike at over 40 km/h then more power to you, but perhaps bike lanes with other, often slower, bikers, aren't the place to it.
Federal law already does that (in the USA, at least). E-Bikes sold in the US can't go faster than 20mph.
You're also right in that e-bikes aren't going to revolutionize commuting anywhere but in crowded cities. It does solve the last mile problem, though. Trains can get you from the country to the city and the ebike can get you through the city faster than anything other than a motorcycle.
They're also fun as hell to ride. :)
As a regular old cyclist I could imagine thinking e-bikers were assholes for using my class II bike lines if there were many more of them on the road, though. I guess if ebikes ever catch on, there will be some growing pains.
There's a continuum of two wheeled vehicles from a kid's BMX bike to a Harley. There has to be an arbitrary cutoff on how much vehicle you can use on a bike path.
Here's what the top end in electric bikes looks like.[1] Out-accelerates a motorcycle. Suitable for dirt-biking. $8000. That has far more performance than a 50cc moped from Wal-Mart for $249.

Plus an hour or so with some spanners and zipties, gets you one of these:
For well under $500. (I think including the battery and the bike, that one owes me under $300.)
I guess I should mention you'll also need a charger capable of charging your chosen battery (I already had two, so I don't factor in the cost of that - you'd be looking at ~$50 or so at the bottom end there...)
Pedego had to recall 5,000 e-bikes after battery fires.[1] There have been some major fires at e-bike shops.

The 7 cell 5800mAHr batteries I use on the bike are the biggest and most dangerous ones I use - and I do treat them with respect. I charge them in the middle of the concrete floor of my garage, inside a besser block, at least 1.5m from anything valuable or flammable. I dispose of them if they go puffy (I've sent two off the the e-waste/battery-recycling in two years - one of them I knew I'd let run down way too far when using it elsewhere, down under 19V which the bike's controller wouldn't ever do (it cuts out at 22V) and it never managed a good charge again, the other I'd been quick charging occasionally (although not really fast enough to explain the shortened lifespan - I can only _just_ hit 2C charge rates with my charger, the battery _should_ be good up to 5C really...))
If you don't know (or want to learn) the risks, or if you're less risk averse (or less able to mitigate the risks due to not having suitable space to let a lipo fire burn itself out) LiFePO4 is a slightly heavier but much safer battery chemistry. I _almost_ got hold of a bunch of cells from a crashed Tesla's battery pack a while back - they'd make a nice ebike power supply. If I can get my hands of enough of them at a reasonable price, I'm planning on electrifying one of my motorcycles with 30+KW of electric power...
(Although you actually get quite a bit for $500, but there's no way to hit that price point without cutting corners)
If you want to increase bike use, build more showers at the workplaces.
The building housing a former sf employer required bikers to use the (slow, smelly, frequently occupied with very slow users) service elevator and store their bikes in a crappy room in the corner of the basement. In what was obviously a hastily converted area. A coworker was locked in the bike storage for 4+ hours. He left at around 2am after putting out some fire, the door to the bike room in the basement was set to lock behind him (yes, this is almost certainly wildly out of code), and the building was solid enough that his cell didn't work from the basement. There were frantic calls to police by his wife. He was found when the basement was opened the next morning.
In lieu of suing everyone in sight we got permission to ride the normal elevators with bikes and to keep them in our office.
Is the real issue that they aren't 'real' cyclists and didn't earn it?
It still makes it really easy to go fast tho, even in jeans and a tshirt, with a backpack full of laptop (and 20+kg too much paunch) - it's pretty easy to out-accelerate most lycra-clad commuters if they don't notice you coming. It's pretty easy to out pace lots of fit looking bicycle riders on long up hill inclines - but if they care, they'll mostly blow past me again doing 40kmh on the downslope on the other side while I'm just rolling along at not much over 25kmh where my assist tops out.
(Safety-wise, my battery weights 850g. The motor and controller add up to maybe 1kg. I'm pretty sure I've seen lycra-louts with more weight in their bidons than my electric assist adds!)
The problem is that 20 kph is really slow. Even into the steady headwinds we have on the coast here, I never travel below this speed, so an e-bike just means a heavy bike for me :-) However, they have revolutionised transportation for the elderly in the countryside. In my town, almost everybody has one. It's really great because it gets people outside and going to shops, etc.
There are now a few electric scooters (classed differently in Japan than bikes). These have a 30 kmh legal speed limit, but they are not physically limited (many, many people drive over the speed limit on these). You need a drivers license to drive these (there is also a special scooter license you can apply for which is easier to get than a general purpose drivers license).
The last category is motorcycle and I haven't seen any electric ones on the road yet, but I'm sure it's a matter of time. Honestly I'd love something like this for going places I wouldn't want to go on my bicycle.
As much as I find it annoying, the categorisation makes a lot of sense to me. Limit unlicensed transport to minor assist only. Put a speed limit on full assist and require a license. Require a full motorcycle license on general transportation that is intended to travel at highway speeds. It's a bit strange to legally be allowed to ride my bike at 40+ kph just because I'm able to do so, though... I just hope nobody changes that law ;-)

Ebikes have the potential to revolutionize transportation in a positive way. Less infrastructure, more dense movement, opens biking to more people with less developed cardiovascular ability.
If I could do 22-25 mph / 35-40kph sustained with a rain suit on, I can beat lots of rush hour car routes, with an output of 10-15mph done by myself, and towing/carrying 20 pounds of stuff, a LOT of car trips become unnecessary.
E-bikes are a bit too expensive for general adoption, but I wouldn't be surprised if they become much more common over the next few years.
Of course, trikes are goofy and don't corner, so there is no real solution here except bike paths designed like interstate highways. One can dream.
I wish more cyclists and drivers actually believed that. As a driver, I'm willing to give a full lane to a biker if they ask for it. (If they're going "too slow", you can always pass in the adjoining lane.) As a biker, sometimes I need that lane; having a several ton car buzzing me on the side is not my idea of fun.
The way I see it is that people are — in general — sloppy, both in their driving and their biking. They think that "cutting corners" is okay.
> which pedestrians never do, they just go for it
(note: grandparent's comment) the problem with this is on a bike is that you're apt to hit a pedestrian. I've seen plenty of bikers on the Embarcadero in SF nearly collide with pedestrians, because the road is a T, and they're on the through road, and mistakenly believe they have no conflicts (they have both the aforementioned pedestrians, as well as any left-turning bikers).
Being on a bike doesn't have the same risk "feeling" AFAICT as a car. A quick glance around to determine "will a car probably hit me if I do this technically illegal thing?" seems to be all it takes.
(Car drivers are just as sloppy, too, just in different ways. I spend about equal time biking and driving, and the number of illegal maneuvers I see in a car on a daily basis is appalling too.)
Most people seem to exemplify Louis C.K.'s "My Favorite Way" (https://www.youtube.com/watch?v=_VAsiC5a02U)
There are a couple of techniques, but both actually require a small amount of forward movement so if it's a long delay then you do creep closer to the car ahead.
But neither is actually necessary; I generally prefer to declip one foot and stick it on the ground as that is quicker and safer particularly when wearing a backpack or conveying a child-seat, since that puts the CoG quite high. But the fact that I had to come to a halt indicates that I didn't correctly manage the approach and I thereby wasted energy.
And please change-down gears as you approach the light. As a fellow cyclist it's frustrating to be stuck behind other cyclists moving-off slowly as they "pedal through molasses" because they're still in a high gear. It annoys drivers, too.
Issues that are probably bigger than "balancing" when you're commuting by bike are: access to safe cycle paths, getting sweaty before work and the weather.
Another convenience in the form factor, to add, stopping and starting do not involve dismounting and remounting, just leg down, leg back up --this means fewer riders running lights or stop signs.
So, if something two wheeled would take over, I'd say the electric scooter rather than the electric bicycle. Now, if you are looking to get a workout during your commute, ok, a pedal bike is better, you have not choice but to pedal.
It basically boils down to: do you have the storage space for a small car, and just want faster highway and street commutes? A scooter makes sense. Do you have to bring it up an elevator or want to use rail trails? E-bike all the way.
Also, sharing the road with cars means breathing their exhaust. Count me in for the e-bike takeover.
On the other hand, people are probably much more likely to switch from a scooter to an e-bike than from a car, simply because the convenience factor is very similar. And winter is coming right now, which luckily takes scooters away too, for some reason :)
