Proud dad Novak Djokovic has posted an adorable photo of his son Stefan learning to ride a bike. The tennis champion shared the landmark moment with his Instagram followers on Thursday, and wrote a touching message in honour of the event. "Parents of the world, I hear you!" the 29-year-old wrote. "This is the most beautiful and the hardest but the most important job we have in life. Grateful that I can treasure these moments forever."
The family photo shows Novak and Stefan – who celebrated his first birthday in October – on their bikes, the little boy gazing over at his daddy. With his hands on the handlebars and his feet on the pedals, Stefan looks ready for action – thanks to a little extra help from some stabilisers.

Novak's son Stefan is growing up fast!
Novak and his wife Jelena welcomed Stefan, their first child together, in October 2014. Announcing the news on his Facebook page, Novak wrote: "Stefan, our baby angel was born! I am so proud of my beautiful wife Jelena. Thank you so much for your love and support. We love you all!!!"
The couple have taken care to keep little Stefan out of the spotlight; in the images they do share of their son, his face is always hidden from view.
The little boy is Novak and Jelena's first child together
Novak and Jelena are currently in London, acclimatising to the city before the start of Wimbledon on Monday. It is not known whether little Stefan is with them, or is being cared for at the family home in Monte Carlo.
The Serbian star is favourite to win the tournament, but he will face tough competition from the likes of Andy Murray. Novak and Andy are the number one and two seed respectively at Wimbledon, and there is much talk of them meeting in the final.

However, the world number one refused to be drawn on the subject during an interview with the Independent this week. "I know there's been a lot of talk about a potential match-up between Andy and me, and with (coach) Ivan (Lendl) coming to his team, but it's still very early," he said. "We have to be respectful to all the players at Wimbledon, more than 120 players, so we take it by step by step."
