Gabriel Scheer, director of strategic development for LimeBike, said the company has no intention of modifying its line of electric-assist bikes to comply with the rule and may have to abandon the pilot program. He said there are fewer bike racks in the area where the companies are piloting the program — from 79th to 138th streets and from the Skyway to Pulaski Road — and filling up racks with rentals could annoy residents trying to store their own bikes.
