More than 50 bikers rode to Arc in the Park to hand over 325 eggs to Ambition, Aspire, Achieve’s Easter egg appeal on Saturday.
The charity is aiming to collect chocolate treats to hand out to underprivileged children in east London in April.
The bikers also handed over £151 in cash to buy even more eggs.
Kevin Jenkins, the charity’s founder, said: “It was a brilliant effort that will make a real difference for local disadvantaged children this Easter.
“It was great to welcome the bikers to Arc in the Park for the first time.”
Youngsters from Forest School in Snaresbrook also donated to the appeal.
