Jan Leif Tinndahn (born 27 January 1961), also known as "Big Jim" and "Solkongen" ("Sun King"), is a Danish outlaw biker and gangster who served as the president of the Bandidos Motorcycle Club in Europe between 1994 and 2012.
[2] Seeking protection from the Hells Angels by joining a larger international club, Tinndahn and the Undertakers contacted Bandidos leaders in the United States and France in 1992.
As leader of the Bandidos, Tinndahn had no intention of adhering to the Hells Angels' protocol, and his club made the Morbids MC across the Øresund Strait in Helsingborg a probationary chapter in January 1994.
[1] On 25 September 1997, he and Hells Angels president Bent "Blondie" Svane Nielsen held a live televised press conference and announced an end to the biker war.
[10] Although not disclosed to the public, Tinndahn and Nielsen had signed a peace treaty designating each club's territory, right down to individual bars, cafés and nightclubs.
[11] During and after the biker war, the eloquent Tinndahn became a figure in the Danish media, participating in television interviews and debates with civic groups campaigning for the removal of motorcycle clubs from the local community.
[20] While Tinndahn escaped with minor injuries, his passenger, fellow Bandidos member Carlos Åkesson, suffered brain damage and remained in a coma until his death on 18 December 2014 as a result of cardiac arrest.
[22] On 28 December 2015, Tinndahn was convicted of aggravated drunk driving, gross negligence in traffic and grievous bodily harm at Malmö District Court and sentenced to nine months in prison.
In August 2020, he made a rare public appearance at a Bandidos "show of force" event in Næstved at a time when the club was involved in a conflict with Satudarah on Zealand.
