"Sucky people" stole Alise Willoughby's custom BMX bike from outside In-N-Out Burger in California.

Alise Willoughby is bummed.

The BMX Rio silver medallist's custom-built race bike was stolen from a parking lot at the Otay Ranch Mall in California while she was having a burger.

"HELP !! STOLEN BIKE"

She posted on social media.

"Unfortunately there’s sucky people in this world that stole my custom race bike..."

Later Willoughby told NBC that “it’s very noticeable, my name is written all over it," and tried to enlist her social media following to help find the bike.

"If seen in person or online please reach out to me...there's only one of these out there and it means something to me, so please help me track down the idiot who stole this and thinks they can make a quick dollar."

Lucky bike

The BMXer said she has gone undefeated domestically riding the bike this year.

And that her biggest race of the year is coming up in three weeks - the Grand Nationals in Tulsa.

“And I don’t have a bike right now.”.

Despite the pleas for help on social media the rider headed into Monday without a bike and had to hit the workshop to try and fit a new one.

"Cruising into this new week with some #MondayBlues missing this pretty thing..," she posted online next to a picture of the stolen bike.

"Time to get on the tools and make some magic happen."

Tokyo dreaming

At Rio 2016 Willoughby came second to double gold medal winner Mariana Pajon from Colombia.

Now the 27-year-old U.S. rider is trying to keep the momentum up with Tokyo 2020 on the horizon.

Alise is being coached by her husband Sam Willoughby, who has an incredible story of his own to tell.

Sam Willoughby paralysed in BMX accident

Alise Post married Australian BMX rider and fellow Rio silver medallist Sam Willoughby on New Year's Eve 2018.

Sam broke his back in a tragic training accident after the Summer Games, but still managed to dance with the bride at the ceremony.

Amazing, considering the doctors declared him tetraplegic just fifteen months before.

Back on the bike

Sam was back on the bike in March and is still coaching his wife in her career.

He is continuing his recovery and rehabilitation while supporting Alise.

The greatest love story on two wheels?

Despite all the setbacks, this couple is still together, maybe even more united than ever.

Just last month Sam posted this message on social media for Alise:

"10 years with this beautiful soul I now call my wife.

This world has thrown us a curve ball or two but together we find a way to slog them all out the park, I look forward to a life time more of home runs with you.

mylove #mybestfriend"
