Jim Papadopoulos bostoni pinc\u00e9j\u00e9ben h\u00e9t bicikli \u00e1ll a falnak d\u00f6ntve. A fest\u00e9k lekopva, a kerekek laposak, a korm\u00e1nyokat por lepte be. Amikor legut\u00f3bb k\u00f6lt\u00f6z\u00f6tt, megszabadult a legt\u00f6bb j\u00e1rg\u00e1nyt\u00f3l, amiken kutat\u00e1sait v\u00e9gezte, \u00e9s csak azokat tartotta meg, amik igaz\u00e1n k\u00f6zel \u00e1lltak a sz\u00edv\u00e9hez. Ezeket haszn\u00e1lta a mindennapokban. Jim azonban, nem a sportnak, hanem a ker\u00e9kp\u00e1r mozg\u00e1s\u00e1n val\u00f3 elm\u00e9lked\u00e9snek szentelte \u00e9let\u00e9t.<\/strong><\/p>\n

Kamaszk\u00e9nt indult amat\u0151r versenyeken, de szenved\u00e9lye val\u00f3j\u00e1ban j\u00f3val m\u00e9lyebb volt. Nem tudott \u00fagy \u00fclni egy bring\u00e1n, hogy k\u00f6zben ne azon gondolkodjon, hogyan m\u0171k\u00f6dik. Hogyan marad egyens\u00falyban rajta a biciklis? Hogyan stabil biciklis n\u00e9lk\u00fcl? Mi\u00e9rt kell jobbra korm\u00e1nyozni, hogyan fordul balra \u00e9s \u00fagy egy\u00e1ltal\u00e1n?<\/p>\n

Ezekre a k\u00e9rd\u00e9sekre kereste a v\u00e1laszt egyetemi \u00e9vei alatt, legt\u00f6bb \u00f6tlet\u00e9t azonban nem siker\u00fclt publik\u00e1lnia. V\u00e9g\u00fcl elhagyta az akad\u00e9mi\u00e1t \u00e9s egy gy\u00e1rban kezdett dolgozni. Munk\u00e1ja odaveszett.
\nLegal\u00e1bbis ezt hitte. 2003-ban azonban egy norv\u00e9g tud\u00f3s, Arend Schwab r\u00e1lelt a kutat\u00e1saira, \u00e9s megkereste a szerz\u0151t, hogy egy\u00fctt dolgozzanak rajtuk tov\u00e1bb. V\u00e9g\u00fcl kiadtak egy tanulm\u00e1nyt, melyben elmagyar\u00e1zt\u00e1k, mi mi\u00e9rt \u00e9s hogyan m\u0171k\u00f6dik ker\u00e9kp\u00e1runkban.
