Electric assist bikes, or e-bikes, assist your pedaling so you can maintain greater speeds or travel further distances with less exertion. A control device on your handlebars allows you to choose between different modes, each offering a different level of assistance. All you have to do is pedal; the electronic motor then engages and adds power to each pedal stroke, giving you an added boost of speed and confidence on every ride. Available on a first-come, first-served basis. Substitutions may be made as needed. E-bikes are offered at a $300 supplement.
