Tern HSD P9 Review

Jan 2024

Price: $3499.00 | Model Year: 2021 | A high-quality midtail electric cargo bike that can stand vertically to save space! Available in three colors but only one frame size. Slack seat tube angle and two telescoping seat post segments provide a range of fit options for short and tall riders alike. This is a proven ebike in my opinion, one that is available in four configurations depending on your appetite for technology, power, and range. The P9 is the most affordable, uses a weaker motor and smaller battery, and is the second lightest in the group.

Observations
  • A high-quality midtail electric cargo bike that can stand vertically to save space! Available in three colors but only one frame size. Slack seat tube angle and two telescoping seat post segments provide a range of fit options for short and tall riders alike. This is a proven ebike in my opinion, one that is available in four configurations depending on your appetite for technology, power, and range. The P9 is the most affordable, uses a weaker motor and smaller battery, and is the second lightest in the group.

  • Lighter and less expensive than the Tern GSD models, the HSD (which stands for Haul Stuff Daily), comes with premium fenders, a custom suspension fork, tool free adjustable-angle Andros stem, and ergonomic grips for added comfort. Compared to the GSD, it offers a lower weight capacity 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. Shimano hydraulic disc brakes provide good stopping power with an extra-large 180mm front rotor. Capable but quiet Bosch Active Line Plus motor pairs nicely with the lightweight and reliable Bosch PowerPack 400.

  • Bosch Purion display is not removable and does not provide USB charging or smartphone app support, but is less likely to get damaged when folding the stem. Limited 105 RPM pedal cadence from Bosch Active Line Plus vs. Performance Line may require more downshifting to climb steep hills. Fewer color options available, and this model comes with the slower Bosch two-amp compact charger.

Tern HSD S11 Review 2023

Jan 2023 · Sam Gross

The bicycle version of a mid-size SUV, the Tern HSD S11 is a cross between a small(ish) cargo bike and a high-speed commuter. The HSD has the stature of a larger folding bike but doesn't fold (though Tern has devised a creative way to store the bike in a compact space), a rear rack that
