Allant+ 8S is a performance e-bike built for riders who want to go far and go fast. The super powerful Bosch Performance Speed motor that assists up to 45 km/h and extra long-lasting battery are perfect for long-distance commuters and avid e-bike riders. This bike also has thoughtful design features created specifically for people who prefer riding their bike over driving their car.

A sleek hydroformed aluminium frame with a fully-integrated 625 Wh Bosch PowerTube battery, an ultra-powerful Bosch Performance Speed (250 W, 85 Nm) drive unit that helps you sustain speeds of up to 45 km/h and a Kiox controller. Plus, a 10-speed Shimano drivetrain, an integrated front and rear lighting system, mudguards, a rear rack and stiff 27.5"" wheels with thru axles.

You're going places, and you want to get there super fast. This bike features Bosch's speediest motor and a long-range battery, making it great for long-distance commuters. You can also increase your range even more by adding Range Boost.

- The Bosch Performance Speed motor and Bosch's longest-range battery let you ride further, faster
- Compatible with Range Boost - an additional battery that can double your e-bike's range so you can ride for longer, commute further and go on bigger adventures
- Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame and makes it easy to remove for off-bike charging and storage
- The full-colour Bosch Kiox controller displays ride info, connects with your Bluetooth? enabled devices and has a built-in theft prevention feature
- It really is ready to roll, with included accessories like mudguards and lights that run off the battery

Goodbye, car. Hello, Range Boost!
Range Boost seamlessly attaches a second long-range 500 Wh Bosch battery to your bike's downtube for up to twice the distance and time between charges. Ride longer, commute further and take on bigger adventures. Range Boost can be added to select Trek electric bike models.
