Built from the ground up to be the ultimate commuter tool. The Stromer ST1X e-bike is the key to avoiding gridlock and showing up at work without getting soaked in sweat. Running late? Need a boost on the hills? Choose the level of pedal assist you want from the controls on the handlebar cockpit. It comes with a powerful 500-Watt motor that accelerates fast, boosts your hill-climbing muscle and gives you up to 120km of range. With the motor built-in to the rear wheel, the design bypasses the drivechain and reduces overall wear and tear. A torque sensor analyzes effort and adjusts the amount of assistance. When braking, the system recaptures energy and feeds it back to the battery to extend charge and limit wear on the discs. When you need to charge it up, the battery is removable so you can bring it inside to plug in (a full charge takes about 4 hours). MyStromer App allows you to connect to the Omni bike control unit and customize your bike’s behaviour, show its location, lock the rear wheel, and manage the theft-mode, as long as it's in cellular network range – no subscription needed. Equipped with a rack and fenders, you can bring home up to 17kg of groceries and fly along wet, dark streets without catching spray off the wheels. For extra comfort and to reduce fatigue, Schwalbe Big Ben tires soak up bumps and vibration from potholes or uneven pavement.
