Enlarge (credit: Peloton) Peloton is having a rough day. First, the company recalled two treadmill models following the death of a 6-year-old child who was pulled under one of the devices. Now comes word Peloton exposed sensitive user data, even after the company knew about the leak. No wonder the company’s stock price closed down 15 percent on Wednesday. Peloton provides a line of network-connected stationary bikes and treadmills.
