In the UK they're limited to 15mph and only operate in assist mode (as opposed to full drive). Where are you that allows that kind of speed?
The limit is a bit annoying, but in practice cars in city traffic aren't moving much faster than this anyway[1]. During rush hours even a limited bike is faster than the cars. [1] https://www.london.gov.uk/questions/2019/19767

I'm just curious if you grew up in a very large city and haven't been to other countries? Because public transport as a primary form of transportation simply isn't feasible in many places. And I was responding to the statement about cars being the worst invention of the 21st century...
It isn't feasible because it was designed around the idea that everyone would have cars. Again, the cars are the reason it was made to be infeasible. Cars damaged our cities.

For anyone who has trouble understanding this perspective because they've lived in car-dependent hell their entire lives, I recommend the Not Just Bikes channel. He does extremely detailed comparisons of US cities vs Netherlands and other places. Here is a recent one [1]. For me, I always felt that something was wrong about American cities / suburbs but I couldn't quite put my finger on it. Then, I spent a few months…
There could be some 'grass-is-greener' effect in play here as well though. Many that grew up having to use public transportation would see being able to use a private car as very appealing. I think everyone hates commutes regardless of whether they have to stand in a packed train car next to sweaty people, or sit in an air conditioned comfortable car listening to music but stuck in a traffic jam. That's not to say th…
The highways in America are super easy to navigate with carplay/gps and to be honest, and I have yet to see a jam where your car is completely stopped for more than 10 minutes. What I see is a dance of cars where every car travels to cruise speed.. another thing I’d mention is that I consider americans good drivers and very respectful of the laws compared to other countries.
Re: Twike
#104I had something similar, although simpler: it's called a velomobile ( https://en.wikipedia.org/wiki/Velomobile ). It's a bike but with some added aerodynamics. You can easily ride at 40km/hour (~24mi) only with your muscles. It was very nice to drive: very stable and rather fast and i did 2x20km/day to work. However its bigger weight compared to a simple bicycle makes it not suitable to mountains
I would love to buy one and do some nice trips in the Italian back country. Problem is, it's very hard to understand which model(s) are well designed, and also hard to understand where to buy it to get the best price. Is there any recommendation you could provide?
It's in German, but you can ask questions in English and they will usually be answered in English as well.
As for your question about which models are well designed, I'd say that if you're looking for speed, the fast ones are the Milan SL, the Alpha 7 and the upcoming Snoek, but those are not suitable for tall and/or wide riders. If you don't fit into those, your best options for speed would be the Milan GT, the DFXL or the upcoming Alpha 9.
If you're rather looking for something more practical, the Quattrovelo is the way to go; it has four wheels and therefore a bigger and more usable luggage space, which can even be used to transport a small child.
Re: Twike
#105I’m currently planning to build a velomobile that I can live out of while cycling round Australia for a year. A trailer too, designed around a digital piano and some sort of fridge (either a production model or one constructed manually from a compressor).
It’ll end up heavy enough¹ that I’ll want to put a motor in it, so that for local journeys I can get from Point A to Point B more quickly and more confidently dispose of my car, and because otherwise when touring there will be some hills that I simply can’t climb, and that 200–250W² should make it possible (though probably still not easy).
So then I figured, how about a fully electrical drivetrain? Even with the best components, it’ll still be a bit less efficient than a well-maintained chain³, but getting the chain and front chainrings out of the way would be great, making the decision of how to facilitate sleep much easier: go quadricycle (rather than tadpole trike, which is two wheels at the front and one at the back), then to sleep tilt the seat back flat, and shift the pedals/generator a bit out of the way, and there’s no chain to worry about so you’re ready to sleep in the vehicle.⁴
Unfortunately, the legislation is drafted in such a way as to forbid such vehicles. Excerpt from Victoria’s Road Safety Road Rules 2017 https://content.legislation.vic.gov.au/sites/default/files/2...>:
> bicycle means a vehicle with 2 or more wheels that is built to be propelled partly or wholly by human power through a belt, chain or gears (whether or not it has an auxiliary motor)
The way they keep talking about power assistance as the use of an auxiliary motor is troublesome, and this potentially doesn’t even allow things like hydraulic, shaft or electrical drives. But then, what is an electrical wire but a belt for electrons?

¹ Though nowhere near the the two-seater Twike’s unladen-save-batteries 246kg. I’m aiming for a this-is-my-home practical loaded long-term touring weight of 125kg, including things like 50kg of vehicle and trailer (including all vehicle electronics), 12kg of piano, 12kg of fridge, 12kg of battery and 5kg of solar panels.
² Broadly speaking, Australia currently has two classifications: 200W with no speed limit, and the pedelec 250W but limited to 25km/h. Finer details vary by state. Not sure if you could legally get away with producing 250W if pedalling and under 25km/h, or 200W if over 25km/h (and pedalling, in some states); “an auxiliary motor capable of generating a power output over 200 watts” hangs quite a bit on the interpretation of the word “capable”.
³ An electrical drivetrain could easily be better than a poorly-maintained chain.
⁴ The main alternatives I’m considering include making the vehicle expandable in a way vaguely reminiscent of a pop-top van, and a larger and/or expandable trailer and sleep in that. But I don’t want to be messing around with tents every day.
Re: Twike
#106There is a similar four wheeled HEHV being produced in Norway: https://www.podbike.com
Wow, the hoops you have to jump through to find a price! 5k or 5.5k, depending on variant. Although to be practicable (not a hobby), you will have to add quite a few "extras". But not that bad actually! Makes me wonder how it is built.
Re: Twike
#107Another example of how, if you had to design a vehicle for passenger city/suburban use, you would never ever ever come up with an ICE sedan, or to be honest even an electrical vehicle of "normal" proportions. Pretty sure the car is the most harmful invention of the 20th century. The damage it has done to the environment, our health, and social fabric is hard to grok. A couple edits for clarification: - I'm talking ab…
> if you had to design a vehicle for passenger city/suburban use, you would never ever ever come up with an ICE sedan I use a motorcycle 90% of the time in the city. But there's a lot of problems with any specialized transport like this: - parking multiple vehicles per person - learning to drive multiple type of vehicles - bicycle/scooter/Twike can't be used for serious shopping - safety. From the time electric scoot…
The variation in task requirements for a vehicle is high, so it is economically efficient to buy a single vehicle suited for as many tasks as possible.
If you can acquire a limited vehicle for a much lower price (including parking, safety, and other externalities) it can be useful to do so -- but the limited vehicles are generally too expensive.

It is probably a good idea to do one or more test drives first, so you know what you are getting into and what is important to you.
Re: Twike
#109Earlier quoted context omitted.
I've had to do all of those things, and still agree that towns and cities being designed with cars as the default mode of transport is insane
It's fine, the main problem is that 90% (imaginary data) of the cars in cities are not used. If all "normal" people used car sharing services or taxis, then a lot of roads could have 1 more lane (where parking normally occurs), which would increase the throughput of the streets. All the peak hour traffic circling around their destination struggling to find a parking spot would also disappear. This would reduce the ov…

A great many European countries have proven it is practical. In fact in some cities it’s more beneficial not to drive (London and Amsterdam to give two examples of wildly different cities yet both favour public transport)
