Allant+ 9.9S is the ultimate e-bike, one that's more than worthy of replacing your car. The super powerful Bosch Performance Speed motor and extra long-range battery let you go fast and far for long-distance commutes and speedy weekend rides. Plus, the light carbon frame is trimmed with thoughtful features designed specifically for dedicated e-bike riders, including a controller that integrates with your smartphone so you can use it for directions, music, and more.

It's right for you if…
A sleek, high-performance carbon frame that fully encases a 625Wh battery, an ultra-powerful Bosch Performance Speed (250W, 85Nm) drive system that helps you sustain speeds of up to 28 mph, and a SmartphoneHub controller that can be used with or without your phone. Plus, a 12-speed Shimano XT/SLX drivetrain, powerful 4-piston hydraulic disc brakes for all-weather stopping power, a Lync front and rear lighting system, fenders, and a rear rack.

The tech you get
Long-range speed and sleek looks-this bike goes the distance. We built this bike from the ground up to be the best in its class. Exceptional design, a super powerful drive system, a carbon frame, and high-end parts all add up to the best way to get around, hands down.

The final word
You get a high-end carbon frame and top-performance parts powered by Bosch's fastest drive system

Why you'll love it:
- You get a high-end carbon frame and parts powered by Bosch's fastest and longest-range drive system
- Download the COBI.Bike app and your phone becomes an on-board computer. Attach it to SmartphoneHub to charge, make or take calls, listen to music, get turn-by-turn directions, and more
- 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 the battery without tools
- It really is ready to roll, with included accessories like fenders and lights that run off the battery
- Compatible with Range Boost-an additional battery that can double your e-bike's range so you can ride longer, commute farther, and take on bigger adventures
