Aluminium and steel
probably in taiwan where most bikes are made
Some of the most durable bikes available on the market today are made by brands like Trek, Specialized, and Cannondale. These bikes are known for their high-quality materials, construction, and components that can withstand tough riding conditions and last for many years.
Most bikes are made in Asian countries, but small-scale production of more expensive bikes exists in most countries.
Most mountain bikes are made from Aluminum, some are made from carbon fiber and older bikes are made from steel. Quality, weight and strength vary hugely by manufacturer with most high end bikes claiming unique methods which either reduce weight, improve strength or both.
If you mean Sunn, they are a French company, but as with most bicycle companies, the majority of their bikes are actually made in Asia.
Yes as are most bikes these days, but not in top road or mountain bike class. They are a USA icon but now, like most bikes, are made in China or Taiwan.
most are made byElectra
depends on the era the bikes of the 80's and early 90's were made in California, after 93 or 94 until today, Taiwan.
Most looked like today's cruisers and town bikes, although there were drop bar road bikes back then too.
They're made from the same basic stuff as most other bikes are made of, no difference there.
Most bikes and bike parts are made in Asia, although there's still a decent number of bikes that gets final assembly in the US/Europe.
Not unless they have grit and stones trapped in the tire treads.... But metals start out as minerals, and most bikes are made from metals.
