Also interesting alternatives that start to pop up are electric personal transportation vehicles like EUC (electric unicycle), e-scooters and similar.

I'm personally using EUC to work in food delivery and I commute to and from area of work. I can make 130km a day with peak speed of 25mph. This is my between-programming-jobs endeavour. I also commuted 10miles one way to my office and it allowed me to skip traffic jams.

I truly believe e-bikes will be the future of transportation. What's holding them back is dumb legislation. In EU, they are limited to 25 km/h top speed and 250 W motors, which is not enough for everybody. Legislators think that if they are allowed to become more powerful then more people will die in accidents. True, but cars kill even more people so why don't we ban them?

For fit people in good weather, 250 W is plenty enough. But not for overweight people or people with movement disabilities. The energy required for movement is proportional to the weight, so it makes a ton of difference if the rider weights 100 kg or only 70 kg. To ride in rain or snow you need sturdier tires which means that the frame and motor needs to be heavier further contributing to the weight.

This issue is solvable but legislation is way behind. If, or when, e-bikes running at 30 - 35 km/h with 750 W motors becomes street-legal, they would become usable by almost anyone. You'd easily do a 15 km commute without breaking a sweat. I know because I've owned a bike like that which I used to ride in the winter. I sold it and bought a regular bike because I realized that I got zero exercise from it. The e-bike was more like a moped than a bike.

I ebike 20 miles for work every day and live it. I don’t use my ebike for small errands because it’s too easy to just rip expensive stuff off of it while locked up. Also, the picture shows a rider with no helmet which is insane. I wear a motorcycle helmet and leathers. The speed limit for ebikes on roads in CA is 28, which is deadly with even a normal bike helmet. Finally the article says that the new models are ligh…

Seconded on the Bafang bbshd. It's a great motor. But I bought the whole bike already assembled with disc brakes, which are essential for ebikes.

I ride a motorcycle to work almost everyday (today's 47 degree ride was a bit brisk) and i have to say, drivers don't look out for bikes, and this is a major city (San Antonio). My big issues with motorized bicycles are lanes to ride and rules of the road. I see people riding them on sidewalks, in streets, and in bike lanes. It is almost like people on motorcycles who ride in the break down lane or lane split (both o…

Where are you suggesting that they ride?

I use an e-scooter rather than e-bike because 1) it's more compact 2) it's relatively cheaper 3) I only go short distances 4) I'm a lazy s.o.b.

Some people will need to sit while riding. Some people need to haul stuff. Some people may need to travel farther. Some people may prefer having weather-shielding. Future cities should allow for a range of micromobility options, not just one thing.

I think this would be amazing for some cities. I've used a electric motorcycle/scooter to commute around San Francisco for 3 years now, and it made me fall in love with the city again. I've used Jump e-bikes to get around as well instead of Uber/Lyfts when I can. (I'd use them more, but their service area stop a mile from my house) Sadly I think SF is a good special case where it works well most of the year: 1. City…

I largely agree with your points as an ebike commuter on the west side of LA which has similar properties (surprisingly compact, protected bike lanes, good weather, very expensive gas).

I also use it regularly to carry groceries via saddle bags and find it to be much more convenient than fighting the parking lot at my local trader joes. Also, it is generally flat here so I don't find the need to shower and change clothes but then again, I bike to work in jeans and a t-shirt so maybe it would be different in a suit?

I converted a nice traditional steel frame bike to with an e-bike kit. I would not really recommend that route - especially not if you’re hauling around a kid or gear like me. I was blowing through brake pads every 3-6 months and for most people it’s probably best to buy a nice e-bike that’s well built and tailored to the task.

No wonder! You definitely want disc brakes on an e-bike. Rim brakes are unsafe due to the increased weight of the bike and generally higher speeds.

I agree that the current EU limits are overly strict, but it's also true that powerful ebikes can accelerate unexpectedly quickly, moreso than is safe for many inexperienced riders or those around them.

Allowing for more powerful motors is fine, and up to 30km/h for top speed is fine, but I think instant acceleration should be the thing that's somewhat more limited than now.

Earlier quoted context omitted.

Helmets are for sports. Ebikes have a ~50% market share in Belgium where approximately nobody wears a helmet ever. It's really not an issue.

Yes and there’s an analogy here between car commuters and car racers. We don’t expect “normal” car drivers to wear helmets. But professional racers absolutely wear helmets. Even in the case of commuters, a helmet could save your life in an accident. For any drivers who thinks bike commuters need helmets, I would encourage you to also get car helmets for you and your loved ones: https://www.amazon.com/RaceQuip-253116-…

If you stop a moment and think carefully, you'll realize that normal car drivers should wear helmets, and passengers too.

It's just that piloting multi-ton metal vehicles at bone-shattering velocities has been normalized. It's always been insane and deadly, but there was an actual concerted effort to normalize it and that worked. I'm not even joking. "Speed demons" were replaced by "Jay walkers" and people have been getting maimed and killed ever since.

Cities need to remove car lanes and add protected bike lanes to really increase adoption. Most parents would not let their kids ride on the road with cars. The car always wins and cars are very dangerous. As far as the schools--they used to be smaller and more local. Now schools always seem to be built on the periphery of a town, take up a massive amount of space and are pretty much designed only for cars/busses. Cars cause cities to be built in ways that are only car-friendly. Hopefully e-bikes provide a revolution in that regard to make other forms of transit equally viable.
