Designed with the needs of the long-distance commuter and the bicycle touring adventurer in mind, the BikeSmart DoubleWide features a one piece double sided saddlebag style pannier made of water-resistant nylon material.
The Axiom Appalachian is a one piece double sided saddlebag style pannier for budget minded commuters.
Water-resistant 600 denier nylon
Easy elastic attachment system
Self repairing zippers
One-piece, double sided design
The high level fabric used in all Axiom bags has exceptionally low off-gassing characteristics (open up a bag and you notice it doesn’t smell like plastic or chemicals!) that exceed even European standards
If you have a traditional bike rack setup on your electric bike (normal size rack tubing and the battery does not conflict with bag attachment) then the possibilities for you are vast! Here is some info on bags and a store that I recommend.
Ortlieb bicycle bags
Ortlieb bags are well known for their high quality construction and they are waterproof.
My friends at Bike Bag Shop also have many other bags that work for commuting, touring and everything in between.
They can also help you select a rear or front rack if your e-bike does not have a rack installed now.
