What are the differences between the batteries?

We offer batteries in all different capacities. For Models C and S we offer a standard 12ah battery with 60 mile range on pedal assist level 2 with an optional upgraded 14ah battery that will give you 100 mile range on pedal assist 2. For Models R and E, we offer a standard 12ah with 60 mile range and an optional upgraded version of 14ah which would get you 70 mile range. We also have basket batteries that start at 10ah for 40 miles range and 20ah double stacked basket battery that will get you 80 miles in pedal assist level 2. Basket batteries can also be added to Models C, S, R, and E for extended range!  Keep in mind that some factors may affect these numbers, including your weight, the wind, and the grade of surface you are riding on.
