Consider your needs Electric bicycles are manufactured for different purposes, people and functions. The best electric bike to buy varies from person to person, and it's up to you to decide which feature is most relevant to your needs. Knowing your personal preferences will help you choose the most important features for your electric bike. If used for commuting and camping, city electric bicycles may be best for you. If you need more climbing ability and comfortable riding performance, you need high-torque hub motors and fat tires. If you prefer to ride long distances, you may need an electric bike with a battery capacity of 400 Wh or higher.
