Summary of the Tern HSD P9 E-Bike Review

the Tern HSD P9, also known as Haul Stuff Daily. If you’ve checked out the S8i model before, you’ll notice some differences. While the S8i boasts an 8-speed internally geared Shimano NEXUS hub, the P9 features a Shimano ALIVIO 9-speed, 11-32 cassette. Both bikes are powered by the Bosch Active Line Plus motor, offering up to 50 Newton meters of torque and 105 RPM motor support—definitely a step up from the standard Active Line.

One of the P9’s standout features is its versatility as a hauling bike. With an impressive weight capacity of 375 pounds, you can load over 130 pounds on the rear rack alone. It’s equipped with awesome panniers and rear seat options, including Yepp child seats and an optional front basket. It’s almost like a folding bike, with foldable handlebars and a double telescopic seat post, making it suitable for riders from 4’11” to well over 6 feet tall.

The P9 uses 20” x 2.15” tires, providing a comfortable ride despite their higher attack angle, which can be a bit jarring on rougher terrain. For taller riders, Tern offers an optional upgrade for the steer post. The Andros Stem, which is adjustable, can be angled forward, down, or up.

Priced at $3,499, the P9 is the most affordable in the HSD range. You’re getting a solid deal for a Bosch drive system, though it comes with the PowerPack 400 battery instead of the 500 and a slower 2-amp Bosch compact charger. The P9 features a 9-speed cassette, but for $600 more, you can upgrade to the internally geared SHIMANO NEXUS hub. Higher-end models like the S11 and S PLUS come with the Performance Line motor, offering 120 RPM support and 65 Newton meters of torque, along with a belt drive system.

All accessories across the HSD models are cross-compatible, including fenders, lights, and battery mounts. The P9 comes with SKS plastic fenders, integrated lights (HERRMANS H-trace 2 LEDs), and the option to upgrade to a higher capacity 500-watt hour battery. The battery placement is low and central, ensuring good balance.

Despite some external wiring, the P9 is easier to service. The frame includes protective stickers, a mid-step design for easy mounting, and numerous mounting options for accessories. The rear rack’s four points allow you to stand the bike vertically, saving space in storage. Multiple color options and an ABUS frame lock keyed alike to the battery add to its practicality.

The Bosch Active Line Plus motor is lightweight at 7.5 pounds, with a responsive controller measuring wheel speed, pedal cadence, and torque over a thousand times per second. It’s equipped with 170 mm crank arms, 160 mm rear disc brake rotors, and a 180 mm front rotor for better stopping power.

The SR SUNTOUR Mobi A32 suspension fork provides preload adjustment for heavier loads and a lockout feature for smoother terrain. Reflective surfaces on the tires, frame, and accessories enhance visibility. The P9’s overall weight is about 63 pounds, including panniers and a front basket.

The Bosch Purion display is simple, intuitive, and offers various assist levels from ECO to TURBO. It features walk mode, which is great for maneuvering heavy loads. The ALIVIO shifters have a convenient optical gear display and a two-way lever for easy shifting. While the pedals could be grippier, they’re replaceable.

The Tern HSD P9 is an impressive, versatile e-bike with a thoughtful design and numerous customization options, making it a great choice for daily hauling.
