Traffic was brought to a halt when dozens of climate change activists staged a slow-cycle roadblock during rush hour.
Extinction Rebellion protesters hoped to raise awareness of ongoing damage to the environment.
After gathering at Central Station, cyclists made their way around the city centre before riding over the Tyne Bridge.
The roadblock came to an end outside Gateshead Council, where activists want a climate emergency called.
Protesters who did not have a bike were armed with placards and flags.
The aim of the cycle event was to slow traffic, attract public attention and distribute leaflets.
The demonstration, which took place at 7.30am this morning, was organised by the North East branch of Extinction Rebellion.
The international movement aim to raise awareness of the factors which they claim will lead to "human extinction" and "ecological collapse".
Extinction Rebellion say they use non-violent civil disobedience in order to achieve radical change.
Campaigners have already lay down on the floor in the Natural History Museum as part of a 'die-in' protest.
They have also marched to Parliament to invite MPs to discuss climate change policies.
