The Pack Rat is specifically designed around porteur-style racks and front-loading optimization.
Having your stuff in front of you means it’s close at hand and easily accessible. It also allows for better weight distribution. We’ve all ridden with a pannier full of groceries. Some of us have wiped out around a sketchy corner and watched as our precious eggs and bananas go flying every which way in an act of Mario Kart-level carnage. A front load keeps the bike nimble and allows you to more efficiently use your body English to steer from the rear and avoid such a super market massacre.
The Pack Rat’s front cargo-specific design eliminates that steering issues but also rides great without cargo. In an effort to jumpstart your front cargo carrying dreams, we include a 24-pack rack on the complete bike version.
The Pack Rat rolls on 26” wheels in the smaller sizes and 650b wheels in the larger ones. Pack Rat’s fork also includes some handy internal routing for generator hubs so you can safely ride off into the night.
