Denver is making progress on its bike infrastructure goals. But the exploding popularity of e-bikes particularly in a city that is putting up as much as $1,700 per purchase so more residents can afford them, raises a question: Is Denver building the right kind of infrastructure to serve a varied group of bike users, some using pedal power and others riding with a motor capable of propelling them at up to 28 mph? Not really, members of the city’s biking community say. “Our street system is just not keeping up with the demand of how people want to be using it,” said Jill Locantore, the executive director of the Denver Streets Partnership, an organization focused on making Denver less car-dependent. With top speeds that well exceed what an average bike rider can do, the potential for conflict between e-bikers and riders on pedal-powered bikes abounds.
