EXCLUSIVE

Lil Uzi Vert got a little too big for his britches on a dirt bike and wiped out during a wild chase with Atlanta PD, which ended with him in handcuffs.

According to the police report ... Lil Uzi and a friend were riding dirt bikes last Thursday night, without lights or helmets. Cops say the duo raced the wrong way down a one-way, drove on a sidewalk and crossed 5 lanes of traffic without signaling.

Cops say the rapper was trying to speed away from officers, but lost his balance and had to ditch the bike. He and his friend tried to flee on foot, but were quickly nabbed.

Uzi was booked for obstruction, reckless driving, not having a driver's license and a slew of other traffic violations. He got out Friday after posting $6,500 bond.

His rep had no comment on the arrest.
