    --- IN THE MEDIA --- 

    “Riding the bike is simplicity itself.”


    “The HSD comes in multiple flavors designed to hit a wide range of price points. The most advanced version even offers automatic shifting thanks to a new partnership with Enviolo.”


    “With the new HSD, Tern has created an interesting e-bike which forms a convenient combination of compact dimensions and high load capacity—and which rides harmoniously and comfortably.”

    Bike Rumor

    “The new HSD is the smaller sibling to the dual-battery GSD e-cargo bike, opting for a smaller footprint in your garage and livelier feeling ride.”

    New Atlas

    “Tern's folding e-bikes have always been ruthlessly practical, but the HSD takes things up a notch.”


    “That small frame makes the Tern HSD handle more like an ordinary e-bike, offering nimbleness rarely seen in a cargo e-bike.”


    “It pushes all the boomer and family buttons with its easy entry and low, stable ride, and the ability to fold flat or stand up on its end make it a great hauler for the millennial in the small apartment.”

    Bike Shop Girl

    “Mark my words, this is the beginning of a new market of electric bikes - the crossover electric bikes. Electric bikes with accessories designed specifically to make biking even more useful and to replace car trips.”

    Belted Blog

    “[The HSD is] part of a new breed of practical car-replacing eBikes that are redefining what a bicycle can do.”

    Rivista BC

    “The evolution of an already evolved species, the new Tern HSD condenses all the ideal characteristics of an urban e-bike.”
