Courteney Cox has given best pal Jennifer Aniston a big push start in her new cycling obsession after buying her a designer $12,000 (GBP6,000) bike. The actress has reportedly bought her former Friends co-star a one-of-a-kind Chanel bicycle after Aniston expressed an interest in hitting Los Angeles' bike lanes. A source says, "Jennifer said she wanted to start bike riding because it's such good exercise. So Courteney sent her the new, ultra-chic Chanel bicycle." The designer cycle has eight speeds and features a quilted leather seat and saddlebag emblazoned with the famous Chanel logo.
