Dutch cyclist Annemiek van Vleuten is in Rio de Janeiro competing in this month’s Olympic games and was well ahead of everyone when she crashed taking a sharp curve. She flipped over her handlebars and was knocked unconscious. At the hospital, it was announced she had spinal fractures and a significant concussion.

Once she was stabilized, awake and feeling better, she tweeted thanks to well-wishers from her hospital bed, assuring them that she’d “be fine” but was “super disappointed,” because  “this chance is 1 in 4 years, doesn’t make it easy.”

But that was when one Twitter bro attempted to mansplain cycling to one of the best cyclists in the world, according to Fusion.

@AvVleuten first lesson in bicycling, keep your bike steady… whether fast or slow.

Mr. Betancourt’s tweet earned him ire from social media users who mocked him for not knowing how to tweet, his incredibly simplistic recommendation and for being both “an ass” and “a d*ck.”

Hi @MartinArielB , what is the second lesson? Annemiek probably waiting.

@MartinArielB I'm not sure how female athletes survived without you for so long. @AvVleuten

@MartinArielB @AvVleuten First lesson of sports watching. Know the basics of the sport if you're going to tweet someone severely injured.

@MartinArielB @AvVleuten mansplaining an Olympic cyclist how to cycle… 😂

— Katja Bego (@katjabego) August 8, 2016

@MartinArielB hope you explained that to Geraint Thomas & Vincenzo Nibali, they clearly also need help on cycling basics #everydaysexism

@MartinArielB @AvVleuten This does take mansplaining to a new idiotic level. I have some tips on carbon reduction for you(no experience)

@MartinArielB First lesson of life: have self awareness.

@MartinArielB could you manage to be any more patronising? I heard no such 'helpful advice' to the men when they crashed #everydaysexism

— DIANE SAMUEL (@dilly_dot) August 8, 2016

@MartinArielB @aftertimeansell @AvVleuten you can take that advice to the bank #stunning 👏🏼👏🏼

@MartinArielB She's an olympic athlete competing at the very limit of human capability. "Keep your bike steady" will not win medals.

@MartinArielB Your mother must be so proud. This will be the only time in your meaningless existence you’ll ever get noticed. #mouthbreather

Betancourt has yet to score any Olympic medals or any Olympic friends.
