There were Huffys and Schwinns, 10-speeds and kids' bikes with streamers on the handlebars. There was even a 1950s-era bicycle from Germany.

Already they were lined up, five and six deep, from the corner of the Eastern Mountain Sports store to the front door, and the cars, trucks and SUVs toting the used bicycles just kept on coming.

"We can't even keep up," volunteer Pat Jackson of Hockessin said as she wrote out another receipt for a donated bicycle.

Jackson and her husband, Tom, were collecting used bikes to be distributed in Third World countries through the nonprofit organization Bikes for the World. In the first two hours of the bike drive Saturday at Eastern Mountain Sports in Center Pointe Plaza, across from Christiana Hospital, about 100 bikes had been donated, putting them on track to top the 200-plus they collected during the first such drive they organized in Newark two years ago.

"You got room for two more?" a man asked, wheeling up a mountain bike. "Can you really find homes for all these bikes?"

"Of course!" Jackson replied, adding a "Holy cow!" under her breath as another truck pulled up, a half-dozen bikes in the pickup bed.

Susan Amert of Newark dropped off three bikes she said her sons had outgrown.

"It's such a great cause, and it's better than putting them into landfills, which are already full," she said.

The organization has shipped more than 18,000 used bicycles to 10 countries, including Guatemala, Costa Rica, Gambia and Namibia.

"We in the United States don't appreciate that in these countries, people don't always have transportation," Pat Jackson said. "But with these bikes, we're making it easier for them to get to their job or to school."

In some countries, the two-wheelers have been refitted to serve as corn grinders or spinning wheels, she said.

Eastern Mountain Sports manager James Howarth said he was pleased at the turnout. People even started dropping off their bicycles Friday night, he said.

Vicki Burdett of Landenberg, Pa., liked the Bikes for the World concept so much she made two trips to the drop-off site on Saturday.

Her Honda Civic couldn't carry all three bikes at once, she said.

"I love to think of all the ways these bikes can be used," she said. "We're so over-industrialized and automated, we forget how the simplest things can be used to really make a difference."
