First review, new Summer Tyres

Part 2 – New summer tyres

 

New summer tyres on my Fitnord Ranger 500 e-bike. The Month of April starts with brand new tyres. Ok, the rear tyre has already about 120 km behind. Both are from Schwalbe. Just as the winter front tyre, these 2 also come with a reflexive side band.

A First review on Fitnord Ranger 500 e-bike

Part 1 – 6 months – 1000 km

I write in English, in order to reach a wider internet group.

Purchased my e-bike mid October 2021. After years of thinking I will get down to building my own, DIY. Spent 2.499 €. At the time, the selection was between 2 sizes : 27″ tyres with 48″ frame, or 29″ tyres with 54″ frame. I chose the larger.

As I am 175cm of height, I’ll confess the frame size is almost, but just almost, out of my size. It means that a) I can barely stand both heels on ground, without crushing my you-know-what, and b) having to lean too far forward in reach handles. This is easily solved by the adjustable (handlebar) center adapter-piece.

Now at time of writing, 6 months later, I have mainly commuted to work. First 3 months it was a tour-retour of 40 km. After having moved my place of living, I’ve got a t-r of 60 km. Passed 1000 km just before the month of April.

Extinguishing, or cooling, an electric car (EV) fire

How to cool down and limit the radius (spread) of an EV on fire? To suppress an EV on fire on a road, or onboard a car carrying ferry?

The facts are :

  • It’s extremely hot near a burning car,
  • there’s a lot of (lethal) smoke emitted from a battery (and car) fire.

Thus, it is difficult to approach a burning EV.

Arbats Barn

Arbats Barn_thumbnail

 

En Triologi utav ryska författaren Anatoly Rybakov.

Titeln kunde även ha varit Barnen av Arbat;

Detta anser jag mera träffande, även om betydelsen är den samma. Dessutom, är den engelska översättningens titel “Children of the Arbat”. På Ryska: Дети Арбата.
