The Los Angeles Police Department responded to a call of a crash back on August 14 a little after 12:30 a.m. at the intersection of West 3rd Street and Flower Street.
Video shared by LAPD, shows several vehicles stopped at a red light, a blue Mini Cooper failed to stop in time and struck the moped driver from behind.
The man on the moped, identified as Miguel Velazquez, was rushed to the hospital with severe injuries, LAPD said.
Velazquez broke both his wrists and injured his tailbone, he said in a social media post. According to Velazquez, the Mini Cooper was driving about 50 mph and launched him about 15 feet.
LAPD said the public should keep an eye on the Mini Cooper driven by the suspect, which sustained damages to the car's panoramic sunroof and likely front-end damage.
There is a $25,000 reward for anyone that could help investigators find the suspect in the hit-and-run crash.
A GoFundMe has been created to help Velazquez.
Anyone with information on the crash is asked to call 213-833-3713.
