Skid Loader is a compact electric cargo bike wired for large loads, small footprints, and everyday deviant behavior.

Just as Easy, Not as Big
Cutting back on car trips is a worthy undertaking, especially in these times of planetary peril. With its electric-assist motor and extreme hauling capabilities, our compact electric cargo bike Skid Loader invites those inclined to throw a leg over and wave their middle digits at downtown gridlock. Built for finding more ways to drive less and ferrying various materials to work, play, or wherever, we gave Skid Loader the utility of a long-tail and a manageable footprint that fits wherever a normal bike does.

Comfortable and compliant under load, Skid Loader also enjoys cutting loose without cargo. Engineered to ride and feel like a regular bike, its 27.5" wheel platform provides abundant tire options you don't get from cargo bikes rolling on smaller wheels. And because it's a Surly, we gave it ample tire clearance and built it for commutes that go from bus stop to bandit trail. We also gave all three frame sizes adequate standover and a dropper post to fit riders of assorted shapes and sizes. Furnished with useful accessory barnacles and internal routing for just about everything, Skid Loader's scaled-down and feature-packed cargo frame removes the roadblocks between you and riding whenever the hell you want.
