    Ebiketips

    “Riding the bike is simplicity itself.”

    Electrek

    “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.”

    Elektrobike

    “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.”

    Electrek

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

    Treehugger

    “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.”
