- HSD S+: Enjoy a care free ride and let your bike handle the shifting. Featuring the Enviolo AUTOMATiQ shifting and an Enviolo Sport 380 hub, your motor and shifter communicate to keep you cruising comfortably and safely.
- HSD S11 Speed: Featuring the Peformance Line Sport motor, designed to propel you past the 20 mph assist limit on other HSDs, with a top assist speed of 28 mph. Includes a 500 Wh battery, front and seatpost suspension, and an Intuvia console.
- HSD P9 Performance: It's the HSD P9, with a derailleur drivetrain and three key improvements: a more powerful motor, a bigger battery and a faster charger. We think the HSD P9 Performance is just perfect for our Bay Area riders.
- HSD S8i Active Line Plus: With a motor that's virtually silent and great for flatter terrain, the HSD S8i includes a low maintenance shifting system that allows you to shift at a stop, and a no mess Gates Carbon belt drive that looks clean and cool.
- Fits Riders from 4’11” to 6’5”: How does Tern do this with one size? Extensive experience in making small-wheel folding bikes that stand up to demanding riders. The HSD features an adjustable design with zero sacrifice to ride quality.
- Child Seat Ready - No Adapter Required: Fits one Thule® Yepp Maxi, Yepp Nexxt Maxi, or Bobike® GO Maxi child seat—no adapters needed. These seats work for toddlers through children up to 4 years old. For older kids or adults, you can use the Captain's Chair.
- Safety & Security: Tern doesn't skimp on the stock setup here – take the built-in Abus wheel lock keyed alike to your battery lock, and Magura MT-4 hydraulic disc brakes for confident stopping.
- Let There Be Light: 190 lumen Valo™ front light provides 24-hour visibility. Herrman's rear light empowers you to ride with confidence – both see and be seen.
- A Warranty You Can Trust: Tern's warranty is backed by The New Wheel True Warranty™ and upheld by our professional service department. Includes 5-year frame coverage, (10 years if you register with Tern), 2 years for the electrical system including the battery, and original warranty for all other components (some exceptions apply).

Our Take
The Tern HSD nests between the folding Vektron and the 2-kid compact utility bike, the GSD. Why should you consider owning the new HSD as opposed to these other models?
Tern has mastered the art of building small wheel bikes, so the Vektron, GSD and the HSD all ride very well, with the same level of performance we expect in all of our bikes. It's truly something you have to feel to believe – a compact bike that rides like a full- size. But folding bikes like the Vektron require have additional complexity (and cost) to achieve the fold. Since the HSD is not a folding bike, the net advantage is that the HSD S8i can offer better cargo capacity, a Gates belt drive and Nexus hub, at a similar price to the Vektron, just by removing folding capability from the frame. And the HSD still does compact for storage or transport.
You also can't miss the design similarities between the HSD and Tern's hugely popular cargo bike, the GSD. The important difference is length and cargo capacity. The HSD will carry one passenger, while the GSD will carry two. The HSD is shorter, and thus easier to stow in your apartment, on transit, or in a car.
Because the HSD shares design conventions found on both the Vektron and the GSD, there is abundant crossover when it comes to useful Tern accessories, letting the new HSD hit the ground running when it comes to daily utility use.
