Kosynier delivers some new machines - fun pics.
I look at these links and what I see is a publicity tour of European cities, a few bikes being shuttled around in a Ford Transit van.  The "European Grand Tour", to promote presale of bikes promised to be delivered in 2022.   

But an internet search showed me no evidence at all that any machine from this maker has been put into a buyer's hands.  Nothing on Facebook or Instagram.  The few videos on U-Tube were placed there by the Bielawski brothers, or are media reports.  I didn't find any reports in forums of anyone being delivered a bike.   This is disappointing, because their 10kW Boardtrack Racer, priced at $10,800 in the US, including $1000 of shipping, had a promised delivery date of July 2021.    https://kosynier.eu/extreme-retro-ebike-kosynier-boardtrack/   

Presale was closed a year ago on the Classics, but now it's open again, and with an announced 1000 euro price increase?

From my perspective, Kosynier has been in this same status of presale and promising, arguably since 2016 when the first articles were published and definitely since 2018 when their Indiegogo campaign was launched.  It's a handsome E-bike, and it would be nice to see some out there being ridden, especially since Juicer bikes closed shop in 2021.

Have you seen any reports of buyers receiving machines?

This is an rather amazing interview with Elon displaying the electric future. You know I'm certainly going to make sure i own couple of horses 🐎 in the future.  ;D

...we're now living in the future...

BBC: Rolls-Royce says its all-electric aircraft 'is world's fastest'
https://www.bbc.com/news/uk-england-derbyshire-59359263

Rolls-Royce believes its Spirit of Innovation plane could be the world's fastest all-electric aircraft.
The firm - whose aerospace headquarters are based in Derby - said the plane reached a top speed of 387.4 mph (623 km/h) during test runs at an experimental aircraft testing site.
It is thought to have set new World Records over three different distances.
The figures have been sent to the World Air Sports Federation for verification.
The test flights took place at Boscombe Down in Amesbury, Wiltshire, on 16 November.
The top speed was achieved by test pilot and director of flight operations Phill O'Dell.
"This is the highlight of my career and is an incredible achievement for the whole team," he said.

I comes from Britain, it's got to be Great. How long does it stay in the air? 5 minutes?

These test flights seem to be about 15 minutes each. That's still a good time for an aircraft to either exceed 380 MPH in a speed run or climb to over 10,000 feet, return & land. Or were you just hoping for a fiery crash & multiple fatalities?

https://www.rolls-royce.com/media/press-releases/2021/15-09-2021-rr-all-electric-spirit-of-innovation-takes-to-the-skies-for-the-first-time.aspx
The aircraft took off from the UK Ministry of Defence’s Boscombe Down site, which is managed by QinetiQ and flew for approximately 15 minutes. The site has a long heritage of experimental flights and the first flight marks the beginning of an intense flight-testing phase in which we will be collecting valuable performance data on the aircraft’s electrical power and propulsion system. The ACCEL programme, short for ‘Accelerating the Electrification of Flight’ includes key partners YASA, the electric motor and controller manufacturer, and aviation start-up Electroflight. The ACCEL team have continued to innovate while adhering to the UK Government’s social distancing and other health guidelines.

https://www.engadget.com/rolls-royces-all-electric-aircraft-completes-15-minute-maiden-voyage-143051424.html
Rolls-Royce, best known in aviation for its jet engines, has taken an all-electric airplane on its maiden voyage. The "Spirit of Innovation" completed a 15 minute flight, marking "the beginning of an intensive flight-testing phase in which we will be collecting valuable performance data on the aircraft’s electrical power and propulsion system," the company announced.
Rolls Royce said the one-seat airplane has "the most power-dense battery pack every assembled for an aircraft." The aircraft uses a 6,000 cell battery pack with a three-motor powertrain that currently delivers 400kW (500-plus horsepower), and Rolls-Royce said the aircraft will eventually achieve speeds of over 300 MPH.
The flight comes about a year after the originally scheduled takeoff and about six months after taxi trials. Rolls-Royce is also developing an air taxi with manufacturer Tecnam, with the aim of delivering an "all-electric passenger aircraft for the commuter market," according to the companies. It has previously teamed with Siemens and Airbus on another e-plane concept.
Aircraft companies have been exploring electric airplanes for a number of years, as air travel and cargo accounts for an increasing amount of greenhouse gases. The World Wildlife Foundation has called it "currently the most carbon intensive activity an individual can make."
Weight is a much bigger problem for airplanes that it is for cars, however. Ford's all-electric Lightning pickup weighs 1,800 pounds more than the gas-powered model, and offers a range that's slightly under half. However, if you added 1,800 pounds to to a Cessna 206 Turbo Stationair, you'd exceed its useful load by 500 pounds before you even loaded passengers (or the pilot) — so it wouldn't even get off the ground.
The project was half funded by the Aerospace Technology Institute and UK government, with the aim of eventually creating all-electric passenger planes. "This is not only about breaking a world record; the advanced battery and propulsion technology developed for this programme has exciting applications for the Urban Air Mobility market and can help make ‘jet zero’ a reality," said Rolls-Royce CEO Warren East.

Schadenfreude? Not exactly, but do you expect me to be overwhelmed? 15min is 3 times more airtime than i've expected which is phenomenal, great achievement.

A small step for man, a giant leap backwards for mankind.

That said i wouldn't mind owning one toy plane like that.

But electric power should work OK for dirigibles. Might want to use helium instead of hydrogen to fill them, though.  ;)

The electric Zeppelin might do it first over the Atlantic you think? Maybe with some additional solar panels on the large surface area after a months voyage or so.

Preferably with on board ambassies and a corona test centre, enough time for sorting all your visas and vaccination passports.

OR we could just skip the battery BS & go for readily available bio-diesel/"bio JP4" with a MUCH higher energy density and smaller eco-footprint. Lifting body aircraft like the Airlander make more sense if you want to go somewhere in a "reasonable" length of time and carry an actual payload. Or we could just sit around with our thumb up our asses making snarky comments "supported" by voodoo logic based alt-right publications.

Yeah, but not without AdBlue, that would be too poluting even if you combust bio diesel. AdBlue however is not available anywhere, so the electric seems to be the only option.

Horses are over-rated.

If you park your bike unattended in a garage over winter the most you need to get it going again is a new battery, often not even that.  If you park a horse unattended in a garage over winter you can guarantee it will never start again.

The other issue with horses is the fuel and maintenance is the same regardless of whether you ride them or not.

oh ... also they bite.  Though at least they do not spit, which the other option, llamas, are prone to do. The llama has never really been popular for personal transport though, probably due to the spitting issue.

@ 294: That doesn't even make sense. There are multiple companies in the aero-bio-fuel biz already, and literally hundreds of thousands of emissions-legal commercial diesel semi's & delivery vehicles in service throughout the EU & USA. The glittering ass-sumption you'd have to be willing to make here to post that is that all the bio-aero folks didn't do their homework & every diesel vehicle is sidelined/OOS because there is no urea-injection fluid available. Neither possibility has a real world analog.

Looks more like an example of "The contrary, the most dangerous kind of Indian- Jack Crabb" in action.

@296: All vehicles made and sold after 2015 complying to EURO 6 equipped with a diesel engine have urea-injection on board to keep the NOx down. That's probably not applicable to aircraft (yet).

Now if you bought for example a super duper 2018 Audi TDI station wagon and you don't fill urea in it than it's going to switch into an emergency mode and you will be limited to an top speed of approximately 15mph to keep the environment clean.

All trucks and lorries are equipped with urea injection for an even longer period of time. With no urea available, supply chains will be disrupted to an even larger degree. And those luxurious super clean sedans may drop in value like a stone. Who would want to fill piss in their cars anyway. Super clean super complex shit, since NOx is almost as deadly as Covid. ( = anyone who died would have died anyway).

You don't even try, you just flail about looking for whatever "seems" right to support the random thoughts flitting thru your head. As long as they are conspiratorial, that's the maximum bang for the buck and you go for it. NOx? Eating a 50 cent box of salt will kill you, as well as 3 Castor Bean seeds.
The only interesting thing I saw was that lots of DEF comes from China & Russia. Restricting DEF supply adversely impacts the economies of the restrictees, a convenient leverage tool. Even more interesting is that the professional in-country watchdogs are not on the job here, they allowed it to happen, just like the (Chinese) microchip "shortage".

A buddy of mine was telling me that he is waiting for this package to pass, so he can get money to replace his water and sewer pipes.

I'm more interested in 33% off on a new E ride.    https://electrek.co/2021/11/20/tax-credits-jump-to-1500-for-e-bikes-7500-for-electric-motorcycles-in-build-back-better-act/
