This is the amusing moment a delivery rider carrying parcels stacked on the back of the bike toppled over backwards.

CCTV footage shows Chiraphat Phuengphal attempting to park in front of a store while a large box, roughly twice his size, was strapped to the passenger seat.

Chiraphat moved carefully through the tight space, but the load pulled him down in Bangkok, Thailand, on May 26.

After reaching the parking spot, he fell flat on his back while a smaller box resting on the handlebars dropped to his face.

The courier worker said: ‘The weight was too much for my vehicle. It easily lifted me.'

Onlookers rushed to help Chiraphat, but he was not hurt as he hit his back and head on the cardboard box behind.
