2022 large Trek E-Caliber 9.6 Gen 2, ridden less than 10 times, selling because we got the wrong size. Ridden gently by my wife. This is a complete e-bike, including the battery and motor. The battery & motor can be removed as a unit and replaced with the included "dummy" battery, which is actually a large storage compartment. It is fully functional without the battery/motor, meaning you can convert it to a lightweight, carbon, full-suspension mountain bike and ride it where e-bikes aren't allowed. It weighs 41lbs 12oz with the battery & motor installed and 36lbs 4oz with the dummy battery & motor installed. The battery and motor is a compact Fazua drive system. From Trek's web site:E-Caliber 9.6 is a carbon electric mountain bike that rides — and looks — like a traditional cross country bike. The compact Fazua drive system lets you do more of what you love with subtle, natural-feeling assist that doesn't overpower the physical and technical challenges of the trail.See https://www.trekbikes.com/us/en_US/bikes/mountain-bikes/electric-mountain-bikes/e-caliber/e-caliber-9-6-gen-2/p/35142/ for full specifications. It is as we bought it.
