The Hanebrink all-terrain vehicle's lithium ion 10 amp hour battery (LiFePO4) will give the bike enough juice for about an hour's use on a single charge, which will take three hours. The rear rack could have up to five batteries fitted which will extend the run time to over five hours. The wide aluminum rear rack is otherwise capable of carrying over 100 pounds of cargo.
After you decide which style of e-bike you want, consider the class. In the US, there are three classes defined by the type of assist and how fast the motor will propel you. Most electric bikes sold are class 1 or 3. Class 1 bikes have a motor (max 750w) that assists while you're pedaling, up to 20 mph. Class 3, also known as “speed pedelec” can also have up to a 750w motor, but it can assist you up to 28mph. Both of those are allowed in most states and cities without license. Class 2 have throttles that don't require you to pedal to get a boost. They're allowed on most streets, bike lanes, and paths, but less popular than the other classes and not covered much here (because we still love to pedal and the greater distances pedal assist bikes can cover).
