People drive for free on electric bikes so i'm wondering how about petrol?

Is there a engine size limit? UK ONLY thanks



Answer
It's a bit tricky. I'm no expert by any means, but I know that an ordinary assisted electric bike which does away with the need for pedalling and doesn't go very fast is quite legal. However some forms of powered transport are not legal for use on anything other than private land, like segways (shame, cos I'd love one!) , motorized foot scooters, and I know the speed can make a difference. That is actually going to be the biggest hurdle - whether something is legal to use on the road or not. Maybe checking out the DVLA website might help.

Who was contributed the most to the world? The UK or Denmark?




Kopper


Things that Denmark has contributed with:
- Carlsberg, the best beer in the entire world, the number one beer drinked by everybody even in the UK
- Lego, best entertainment in the world
- Best food in the world, lots of Danish restaurants even in the UK

Things that the UK has contributed with:
- Fat old men for thai women

I think Denmark wins, hands down.
Denmark is also more of a world power. Look at how much the elite soldiers of the kingdom of Denmark are contributing in Afghanistan while the British soldier do nothing. America knows that Denmark and Danish soldiers are amongst the best soldiers in the entire world.

British Discoveries:

DNA â James Watson and Francis Crickâs discovery in 1953 of the double helix structure of DNA, pictured below, the genetic code for all living things

Genetic fingerprinting â Alec Jeffreysâ development in 1985 at the University of Leicester of a reliable way to detect differences in individualsâ DNA

Birth of the first working computer â Freddie Williams and Tom Kilburn, two University of Manchester scientists, are credited with running the worldâs first stored programme computer

Contraceptive pill â developed by Herchel Smith, a researcher at the University of Manchester, in 1961

Cancer and cell division â in 1987, Paul Nurse and Tim Hunt, scientists for Cancer Research UK, became the first to identify the key genes that govern and regulate cell cycle and division

CDs, DVDs and the internet â these have all been made possible through a technology called strained quantum-well lasers, which was first proposed by Alf Adams at the University of Surrey

The Gaia hypothesis â James Lovelockâs development of a revolutionary way of thinking about the Earth with the idea that it is a self-regulating living organism

Eradicating the tsetse fly â scientists at the University of Greenwich have been working to eradicate the tsetse fly from Africa through the use of an artificial cow, which attracts the fly and kills it through insecticides

Stem cells â Research by Martin Evans led to the discovery of embryonic stem cells, which have the potential to grow into the different cells that make up the body

Microscopic footballs â Harry Kroto at the University of Sussex, and his US collaborators, revealed that carbon can exist as tiny spherical molecules
