Comparing the Tern NBD S5i vs. Tern HSD P5i (Gen 2): A Close Look at Two Urban Powerhouses

When it comes to electric bikes designed for urban and commuter use, both the Tern NBD S5i and Tern HSD P5i (Gen 2) stand out with powerful motors, sleek designs, and essential features. While they share several core qualities—such as their mid-drive motor systems, foldable designs (for the NBD S5i), and high-quality materials—there are notable differences that may sway your decision depending on your needs. The NBD S5i, which debuted in 2022, is all about compact convenience, with its lightweight frame and foldable design, perfect for tight storage spaces and easy transport. In contrast, the HSD P5i (Gen 2), released in 2023, offers a more robust build and larger cargo capacity, aimed at riders who need a bit more muscle for heavier loads or even family transportation. So, which bike suits your needs better? Let's break down the unique strengths of each model.

Why the Tern NBD S5i Might Be Right for You

While the Tern NBD S5i and its larger sibling, the HSD P5i, are both powered by mid-drive motors, the NBD S5i stands out with its portability. If you’re looking for a bike that’s easy to fold up and store in a small space, the NBD S5i delivers with its compact folded dimensions—making it the ideal choice for those in tight living situations or city apartments. Weighing just 51.6 lbs, the NBD S5i is lighter than the HSD P5i, making it more manageable for carrying and navigating through urban environments. Plus, the 264.6 lbs weight capacity should be more than adequate for most riders.

Another significant advantage of the NBD S5i is its 500 Wh battery which, when paired with the 4 levels of pedal assist, offers an impressive 74 miles of range—a decent distance for most commuters. Although it doesn’t support fast charging like the HSD P5i, it is still a solid performer for daily city riding. This bike also features a convenient USB charging port to keep your devices powered on the go.

What the Tern HSD P5i (Gen 2) Brings to the Table

The Tern HSD P5i (Gen 2) is built with a more robust frame and is aimed at users who need a versatile bike capable of carrying heavier loads, such as cargo or even a child’s seat. It boasts an impressive 397 lbs rider weight capacity, making it the best option for those who need extra durability and support. The 545 Wh battery, coupled with automatic gear shifting, delivers a range of up to 80 miles, just edging out the NBD S5i’s range, which can be a game-changer for longer commutes or weekend trips.

One of the major highlights of the HSD P5i (Gen 2) is the advanced 250W motor, which offers a peak output of 500W. This power helps the bike handle steep inclines and cargo loads with ease, while the Shimano Nexus 5-speed hub gearing system ensures smooth shifting without the hassle of manual adjustments. Additionally, the HSD P5i (Gen 2) features regenerative braking, an excellent safety feature that’s not available on the NBD S5i, making it more suited to those who require advanced safety on their rides.

While the NBD S5i focuses more on portability, the HSD P5i is built for strength and versatility, and it excels in features like anti-theft alarm and tracking, adding a layer of security that the NBD S5i lacks. Plus, its frame and suspension are more geared for those who intend to use the bike for more than just a quick commute—whether it’s for carrying groceries, luggage, or other personal items.

Quick Take

In a nutshell, if you prioritize portability and lightness with great range for daily city commuting, the Tern NBD S5i could be your ideal match. On the other hand, if you need more versatility, carrying capacity, and features like regenerative braking and anti-theft tracking, the Tern HSD P5i (Gen 2) will undoubtedly be the more compelling option.

Closing Recommendation

Both of these bikes offer fantastic features and performance, but the choice boils down to what you need. The Tern NBD S5i shines with its portability and lightweight build, ideal for urban dwellers who want a bike that's easy to store and carry around. Meanwhile, the Tern HSD P5i (Gen 2) takes the crown if you're after a more powerful, cargo-friendly bike with extra features to handle larger loads and longer distances with enhanced safety. For everyday commuting in a compact form, the NBD S5i is hard to beat, but for those seeking power and capacity, the HSD P5i (Gen 2) is the clear winner.

Verdict

  • Winner → Tern HSD P5i (Gen 2) - Stronger build, better cargo capacity, regenerative braking, and more security features.
  • Runner-up → Tern NBD S5i - Lighter, foldable, and more suited for compact living and city commuting.
