Tern launches next-gen Vektron folding e-bike in the US – now with belt drive

Tern’s popular Vektron folding e-bike just got a big upgrade for the US market. The urban mobility brand has announced the launch of the fourth-generation Vektron, now available in two models, including a long-awaited belt-drive option that promises lower maintenance and a cleaner ride.

The Vektron has been a fan favorite for years, appealing to city riders, multi-modal commuters, and travelers who want a premium e-bike that folds quickly and stores easily. The new version retains its fast-folding frame, Bosch mid-drive motor, and compact portability, but introduces key improvements in comfort, ride quality, and drivetrain options – most notably the new Vektron P5i with a Gates Carbon Belt Drive. While the new version came to other markets a few months ago, the US is finally getting a chance to ride the new model.

“The Vektron has been a solid favorite of Tern riders, whether they are multi-modal commuters, urban dwellers in need of an e-bike that stores in minimal space, or campers looking to easily include an e-bike in their travels, ” explained Steve Boyd, General Manager at Tern USA. “This 4th generation introduces several important improvements while retaining its category-leading combination of Bosch mid-drive power, superior ride quality, and incredibly fast and easy folding action. We’ve also added a belt drive model and, through careful component choices, managed to deliver competitive pricing despite cost increases due to tariff pressures.”

Paired with a Shimano Nexus 5 internally geared hub, the Vektron P5i is designed for ultra-low maintenance and daily convenience. For those who prefer a traditional derailleur setup, the Vektron P10 is still available with a 10-speed Shimano Deore drivetrain and a more aggressive geometry.

But it’s not just the drivetrain that got a refresh. Tern borrowed design elements from its popular GSD and HSD cargo bikes to give the Vektron a more upright and comfort-focused cockpit. Riders get a taller stem, swept-back handlebars, and better weight distribution, offering a more relaxed riding posture ideal for urban cruising.

Despite its compact size, the Vektron delivers big design features. Reinforced frame components, including Tern’s robust OCL+ folding joint, give it a stable and confidence-inspiring ride that the company says sets it apart from other folders on the market.

Folding takes less than 10 seconds, and once compacted, the bike rolls easily on its own wheels – no awkward lifting required. It tucks neatly under a desk or next to a workstation, offering a secure indoor parking solution for city riders wary of bike theft.

Importantly, both new Vektron models are UL 2849 and EN 15194 certified, ensuring the electrical systems meet rigorous safety standards – a welcome reassurance in a market increasingly crowded by low-cost, uncertified imports.

The Vektron P10 will retail for $3,699 USD, while the belt-drive P5i model comes in at $4,099 USD. Both are expected to land in North American bike shops by the end of the year.

Electrek’s Take

Tern definitely deserves its place as one of the leaders in premium folding e-bikes that don’t compromise on ride quality. The addition of a belt-drive model is a major win for commuters and anyone tired of greasy chains and derailleur tune-ups. And in a market where safety certifications are becoming more critical, it’s good to see Tern doubling down on UL compliance. With the new Vektron, it looks like the Goldilocks of folding e-bikes just got even better.
