An electric bike, often referred to as an e-bike, is a bicycle with an integrated electric motor. E-bikes look and handle like standard bikes but provide the benefit of electric assist. For most e-bikes, riders can expect to travel 20–50 miles on a single charge; some pricey units can do 70 miles.
This October, dozens of A. James Clark School of Engineering students attempted to shatter the average range of an e-bike by participating in the college’s 125-Mile EBikes! Design Competition, offered as part of the Clark School’s 125th anniversary this year.
