Summary of the Tern HSD S8i Review

Tern HSD S8i, an electric bike that stands for “Haul Stuff Daily.” Unlike its sibling, the GSD (Get Stuff Done), which is a heavy-duty cargo bike, the HSD is a more compact and versatile option, capable of carrying up to 170 kg (around 370 pounds). It’s perfect for one child seat or a petite adult on the back, making it a fantastic choice for urban families or anyone needing a robust yet manageable e-bike.

One standout feature of the HSD S8i is its front suspension fork, a significant upgrade from the rigid setup on the GSD. This addition, along with its narrower but still substantial 2.15-inch tires, ergonomic grips, and a Velo saddle, ensures a smooth and comfortable ride. The bike’s tires provide puncture protection and reflective sidewall stripes for added safety.

The HSD S8i is designed with practicality in mind. Its 20-inch wheels make it easy to load and unload cargo, and the bike’s frame allows for a low step-over height, making it accessible for riders of all sizes. You can even fold down the handlebar and stand the bike on its end, making it easy to store in tight spaces like closets, offices, or elevators. This feature, combined with a folding handlebar that swivels and folds down, adds to its urban utility.

Under the hood, the HSD S8i boasts a Bosch Active Line Plus motor paired with a Bosch PowerPack 400 battery, providing a balanced and efficient power source. The motor is whisper-quiet and delivers enough torque to handle city commutes and light cargo hauls with ease. For those wanting more power, Tern offers the S+ model with a Bosch Performance Line motor, which provides 65 Nm of torque and a higher cadence support of up to 120 RPM.

One of the most exciting aspects of the HSD S8i is its Gates carbon belt drive and Shimano Nexus internal geared hub. This combination is not only cleaner and quieter than traditional chain systems but also more durable and low-maintenance. The bike’s hydraulic disc brakes, with 160mm rotors in the rear and 180mm upfront, provide excellent stopping power, essential for safety when hauling cargo.

Safety features are plentiful on the HSD S8i. Integrated lights, including a high-mounted headlight and a rear light with two LEDs, ensure visibility. The bike also comes with reflective graphics and sidewalls. Additionally, Tern includes an Abus frame lock, using the same key for the battery lock and the cafe lock, enhancing security during quick stops.

Despite its robust build, the HSD S8i remains relatively lightweight at around 56 pounds, making it manageable for most riders. Tern has also designed the bike to accommodate a wide range of rider heights, from 4’11” to 6’5”, thanks to its telescoping seat post and adjustable Andros Stem.

In summary, the Tern HSD S8i is a premium compact cargo e-bike that combines the convenience of a folding bike with the durability and performance of a full-sized e-bike. It’s perfect for urban dwellers who need a reliable, comfortable, and versatile bike for daily commutes and errands.
