Tern Vektron S10 Electric Folding Bike
Folding down in just 10 seconds, the Tern Vektron S10 Electric Folding Bike will help you get to work without breaking a sweat, and pack away neatly once on the train, bus or at the office. It delivers a stiff and stable ride even when fully loaded, and can be resized without tools in order to fit riders between 147 and 195cm tall.
The Bosch Performance motor delivers 250 watts of power with a maximum assisted speed of 15.5 mph / 25 km/hand and pairs with a Bosch PowerPack 400Wh battery to provide up to 68 miles of range depending on mode and terrain. There's a Bosch Purion display that sits on the handlebar and can be used to view stats and switch between the four modes. There's also a walk assist mode so pushing your bike is less of a slog.
The integrated Atlas V Rack™ can be transformed into a safe, comfortable space for your little one to sit with the addition of a Thule Yepp Maxi or a Dash® RM seat (purchased separately), or you can load it up with shopping or other cargo. Front and rear lights are included for nighttime riding, along with mudguards for protection in wet weather and a chainguard to prevent trousers or a skirt from getting caught in the drivetrain.
