Downtowns, particularly college towns, make room and rules for new pedicabs.

Pedicabs, adult-size tricycles with room in the back for passengers, have gone from the occasional tourist attraction to a more prominent means of public transportation, prompting a race by cities to beef up safety ordinances amid backlash from automobile cab operators.

In New York City, a string of traffic accidents and brawls involving pedicab drivers prompted officials to impose new regulations. By Nov. 20, all pedicab businesses must be registered and licensed with the New York City Department of Consumer Affairs.

"The New York Police Department will enforce this law to the fullest extent," said Consumer Affairs spokeswoman Elizabeth Miller. Operators must agree to an annual safety inspection, too.

Since the licensing process began, 16 pedicab businesses have applied, with 77 affiliated pedicabs and 80 drivers, but the office hopes to see a rush just before the deadline, Miller said. "By the industry estimates, there are over 1,000 pedicab drivers on the street," she said.

It's not just a big-city issue. Dan Werner, director of sales and marketing for manufacturer Main Street Pedicabs, said he used to sell primarily to big cities but has seen an increase in orders from what he calls "small-town USA." Recently, he fielded pedicab business inquiries from Akron, Ohio; Sandpoint, Idaho; and Modesto, Calif. Some of the interest is generated by the public's thirst for environmentally friendly travel options and ways to avoid traffic during big events, he said.

"The downtown life is big for pedicabs," he said, particularly in college towns.
