New Zealand's Sarah Walker - Source: Photosport
A proven world beater, this week's hottie is a brunette stunner who will really get your wheels spinning.
Sarah Walker started riding BMX in 1999 and has gone from strength to strength ever since.
The 21-year-old was one of the favourites to win the women's event at the Beijing Olympics in 2008.
She ended up fourth but we won't hold that against her, she is one of a select few who can make a jumpsuit and helmet look sexy.
In July this year, Walker won the BMX World Championship in Adelaide.
Check out the video of her winning that event
