The teenager accused of fatally crashing a mini-motorbike into a woman on a zebra crossing has been committed to stand trial, after a witness told a court he saw several riders "flying past".

Caleb Jakobsson, 19, on Tuesday pleaded not guilty to culpable driving causing death and 12 other charges over the death of Andrea Lehane in September last year.

Police allege Ms Lehane was thrown up to seven metres when hit by a mini-motorbike, also known as a "monkey" bike, when hit at 30km/h on the afternoon of September 23 outside a Carrum Downs shopping centre.
