Considered one of Taiwan's most promising cyclists in his generation, Feng sought headlines on the international scene as he outsprinted Japanese duo Kazuhiro Mori and defending champion Makoto Iijima for the gold medal in men's point race at the 2007 Asian Cycling Championships in Bangkok, Thailand.

[5] Signifying an official start of his cycling career, Feng qualified for the Chinese Taipei squad in the men's points race at the 2008 Summer Olympics in Beijing by receiving a wild card invitation from the Union Cycliste Internationale (UCI).

[5][6] Feng dropped out of a grueling 25-km sprint race in a field of twenty-three cyclists after he slowed down his own pace on the track with only one extra lap needed to complete and a deduction of twenty points.

At the 2012 Asian Cycling Championships in Kuala Lumpur, Malaysia, Feng ended his five-year drought by edging out Thailand's Turakit Boonratanathanakorn and home favorite Harrif Saleh on a sprint ride for the gold in the men's elite 10-kilometre (6.2-mile) scratch race.

[12] In early 2013, Feng joined his fellow Olympic riders Zachary Bell of Canada and Wu Kin San of Hong Kong for the Champion System pro cycling team.
