Question: What genre of film do "Bicycle Dreams" and "Youth in Crisis" share?
Context: David Clinton (born January 2, 1960 in Sun Valley, California) is an "Old School" former professional Bicycle Motocross (BMX) racer whose prime competitive years were from 1973 to 1979.  Nicknamed "Dynamite" early in his career David Clinton could be truthfully said to be the sport's first true superstar.  He was the first racer to win an official National No.1 plate of any kind when the first BMX sanctioning body, the National Bicycle Association (NBA), introduced the title in 1975.  During the previous year he won the junior class division of a series of what could be called proto Nationals, a part of the first major BMX series, when he took first place in the Junior class at the Yamaha Bicycle Gold Cup which decided the California State Champion.  Clinton along with Scot Breithaupt and John "Snaggletooth" Palfryman participated in the first true National sanctioned by the NBA in Phoenix, Arizona in 1975 and became the first official pro in BMX in 1977 (although Thom Lund could be considered the first BMXer to race for money.  He raced for a share of the US$200 purse and won the Scot Breithaupt sponsored Saddleback Park race in Irvine, California in 1975). The Morgul-Bismark Loop is a popular cycling route or stage south of Boulder, Colorado.  It was featured in the bygone Red Zinger Bicycle Classic and Coors International Bicycle Classic, and is still commonly ridden today.  Riders who have traversed the stage include Greg LeMond and Davis Phinney.  The course was also used by the Red Zinger Mini Classics youth road bicycle racing series from 1981-1992. Ruthie Matthes (born November 11, 1965) is an American professional bicycle racer who won the World Cross-Country Mountain Bike Championship in 1991.  She is also a road cyclist, having twice finished in 2nd place in the Women's Challenge bicycle stage race.  Ruthie is one of a series of professional riders who got their start in cycling through the Red Zinger Mini Classics youth bicycle race series in Colorado. Silicon Dreams Studio Limited was a British video game developer based in Adderbury, England, founded by Geoff Brown in March 1994 as the in-house development team for video game publisher U.S. Gold, also founded by Brown, and became part of the CentreGold umbrella.  In April 1996, the entirety of CentreGold (including Silicon Dreams) was acquired by Eidos Interactive for GB£ .  However, in December 1996, Brown re-acquired a 75% share in the Silicon Dreams label for at least GB£ , and merged it into a new, legally incorporated entity, Silicon Dreams Studio, which became a subsidiary of Geoff Brown Holdings (later renamed Kaboom Studios).  In August 2003, Kaboom Studios, facing financial difficulties, closed down sister studio, Attention to Detail, which led media to expect similar to happen to Silicon Dreams Studio.  Silicon Dreams Studio entered liquidation on 3 September 2003, laying off all of its 55 employees.  A successor to the company, Gusto Games, made up from eleven former Silicon Dreams Studio staff, was announced in October 2003.  Gusto Games went on to finish work on "Urban Freestyle Soccer", which was released in December 2003. Bicycle Dreams is a 2009 documentary film by director Stephen Auerbach about the Race Across America, a 3000-mile cross-country bicycle race.  The film has won numerous film festival awards and had a successful screening tour. Youth Outreach (Chinese: 協青社) is a non-profit organizationibasedn Hong Kong established in November 1991 as a crisis intervention center for youth.  In the years since its establishment, the organization has been devoting its services to help youth in critical condition or those who face major crisis in their life.

Cycling in Munich accounts for 17% of all traffic in the German city of Munich.  This makes Munich the leader in bicycle modal share amongst the large German cities; as a result, Munich named itself Germany's "Radlhauptstadt" (bicycle capital) in the summer of 2010.  Around 80% of the population of Munich own a bicycle. Vélo'v is a bicycle sharing system run by the city of Lyon, France, in conjunction with the advertising company JCDecaux.  It has been the pioneer smart bicycle sharing system, previous systems being more ad hoc and run similar to a charity.  The relationship with JCDecaux allows the city to provide the service on a cost neutral basis for the city, and at very low cost to users, in return for providing exclusive advertising access on bus shelters and the like.  The primary aim is to reduce vehicle traffic within the city.  The scheme also aims to reduce pollution, create a convivial atmosphere within the city, and encourage the health benefits of increased activity.  Its name is a portmanteau of French "vélo" ("bike") and English "love".  The first bicycle sharing system to open in France, after the pioneering 1974 scheme in La Rochelle, its thundering success inspired similar systems in major French and European cities, including Paris' Velib' in 2007.  With the success of these two high profile smart bicycle sharing systems a new paradigm of government supporting bike sharing as a part of a public transportation network emerged.  It is still the bike share scheme with the second highest market penetration (1 bike per 121 residents) in the world, after the Velib'. Youth in Crisis is a 1943 American short documentary film produced by Louis De Rochemont as part of "The March of Time" series.  It was nominated for an Academy Award for Best Documentary Short. Cycling is a ubiquitous mode of transport in the Netherlands, with 36% of the people listing the bicycle as their most frequent mode of transport on a typical day as opposed to the car by 45% and public transport by 11%.  Cycling has a modal share of 27% of all trips (urban and rural) nationwide.  In cities this is even higher, such as Amsterdam which has 38%, though the smaller Dutch cities well exceed that: for instance Zwolle (pop.  ~123,000) has 46% and the university town of Groningen (pop.  ~198,000) has 31%.  This high modal share for bicycle travel is enabled by excellent cycling infrastructure such as cycle paths, cycle tracks, protected intersections, ubiquitous bicycle parking and by making cycling routes shorter, quicker and more direct than car routes.
