I'm selling this because I purchased and installed it, but I haven't used it for even 5 hours in total. Perfect for indoor training. The KICKR is a smart trainer that allows you to control resistance and monitor training progress using a smartphone, tablet, or PC. It supports popular apps like ZWIFT and various other training apps. You can enjoy virtual rides while training, as you can feel the resistance change automatically according to the course and check your training progress. Connectivity with each device is the same as the KICKR. It supports ANT+, ANT+ FE-C, and Bluetooth, allowing for wireless pairing with iOS, Android, and PCs (Mac, Windows). By linking with the latest devices such as "KICKR CLIMB" and "KICKR HEADWIND," you can even simulate changes in virtual course gradients and headwinds, enhancing the immersion and realism of virtual rides more than ever before. ● Part Number: WFBKTR120 ● KICKR Version: 5 ● Shipping Weight: 55 lbs (24.9kg) ● Box Dimensions: 26 inches x 12 inches x 22 inches (66cm (length) x 30.5cm (width) x 55.9cm (height)) ● Product Dimensions: 51 x 71 x 44cm - Leg Open Configuration ● Weight: 47 lbs (22kg) ● Drivetrain: Belt Drive ● Resistance Type: Electromagnetic ● Accuracy: + / - 1% ● Wireless Solution Updates: Yes.
