Tern HSD S8i Review - $3.8k

Published at : 23 Dec 2025

The Tern HSD S8i is a high-quality midtail electric cargo bike that can stand vertically to save space! Available in eight colors (four for the S8i configuration) but only one frame size. Steep seat tube angle and two seat post segments provide a range of fit options for short and tall riders alike. Lighter and less expensive than the Tern GSD model, the HSD (which stands for Haul Stuff Daily), comes with premium fenders, custom suspension fork, adjustable-angle Andros stem, and ergonomic grips for added comfort. Compared to the GSD, it offers a lower weight capacity overall and can only handle one child seat. Comfortable and stable Schwalbe Big Ben tires provide puncture protection and reflective sidewalls to keep you visible. Premium integrated lights with excellent headlight position and aiming. Magura hydraulic disc brakes provide great stopping power with extra-large 180mm front rotor. Capable but quiet Bosch Active Line Plus motor pairs nicely with the lightweight and reliable Bosch PowerPack 400... Tern chose the faster 4 amp Bosch ebike charger! Bosch Purion display is not removable and does not provide USB charging or smartphone app support... but it's less likely to get damaged when folding the stem. Limited 105 RPM pedal cadence from Bosch Active Line Plus vs. Performance Line. Gates Carbon belt drive is quiet and reliable, the Nexus 8-speed internally geared hub is durable and can shift at standstill, but these features add cost and the IGH adds weight.
