An Update of E-Bike Purchase Incentive Programs in North America
John MacArthur
The electric bicycle (e-bike) is a low-emission mode of transportation that offers communities benefits in the areas of health, planning, time, cost, street safety, congestion, air pollution, noise pollution, and energy security (Benoît et al., 2011). E-bikes enable more people to ride a bicycle for longer distances despite physical limitations, difficult terrain, and the presence of cargo (MacArthur et al., 2018). In the most recent U.S. National Household Travel Survey (NHTS), completed in ...
