Start Your Build
- Bosch Drive System: The best, most reliable drive system, with the power for taking you and your things up the steepest hills.
- New! P9 Performance Edition: It's the HSD P9 (i.e. derailleur drivetrain) with 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.
- Pick your drivetrain: Choose from either a standard derailleur shifting system on the P9, or a low maintenance Gates Belt Drive with a simple Shimano Nexus internally geared hub on the S8i.
- 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 hydraulic disc brakes for best of class stopping performance.
- 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.
- 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.
