Folding e-bike, Gen 3, and the cheapest Vektron build (the P10 is $3,699 and the P5i $4,099). Listed at $2,999 as a sale price with no regular price shown. Folds in 10 seconds to 42 x 86 x 68.5 cm and resizes for riders 147-195 cm. Bosch Active Line Plus at 50Nm, Class 1, 20 mph in the US. The Bosch PowerPack 400 "clips on and off your bike". Integrated Atlas V rack rated 27 kg: the spec table converts that to 60 lb and the feature copy to 59 lb; the spec table is recorded. Max gross vehicle weight 125 kg (276 lb), rider limit 105 kg (232 lb). Tern's own spec note says the 21.9 kg (48.3 lb) weight may not include racks and fenders. Shimano hydraulic discs (rotor sizes not listed), 1x9 Shimano Alivio, front and rear lights, fenders and kickstand included. Frame is recorded without a step-through value because the page does not describe one. Tern publishes a generation rather than a model year; 2026 is the year it was read. Sold through dealers, so stock is not shown.

Safety certification: UL 2849: full system. Tern states: “Tern ebikes use e-bike systems that are certified to UL 2849” (source). That is the manufacturer’s own claim, not something we verified, you can check a specific model in UL’s Product iQ database. Why this matters.
