Everything is improved by bubbles, Yunzie.

We've entered the last two hours of the RideLondon FreeCycle for this year, and hasn't it been a whole load of fun? 

How are you spending the last couple of hours? Maybe you'll be going for an ice cream, or using the time to scope out the nicest place to grab some dinner afterwards?

We're still keen to hear from you, and to see your best pictures of London of course, so get in touch on Twitter by using #RideLondon.

If you're considering getting serious with your cycling, one of your priorities should be getting the right bike. 

Using a bike that doesn't fit you can be awkward, and potentially damaging to your body as well. 

Make sure you have the best bike for you by following British Cycling's top tips.

The Bristows are turning out in force for the FreeCycle...can anybody top this lot?

Having overcome cancer himself, Bryan, 72, was left shattered when his daughter, Cathy, was diagnosed with breast cancer in January 2016.  

Cathy, who represented Great Britain at triathlon in two world championships in the 1990s, has lent her dad the bike she used whilst competing for her country.  

"My wife and I were devastated. [We were] faced with a sense of helplessness," he said. 

"Apart from supporting Cathy's husband and two young children, I decided the only thing I could do would be to get on my bike.  

 "At 72 I am quite apprehensive, but I shall take inspiration from riding on the bike that Cathy used for her two world championships."

There are lots of kids around on different bikes: bright pink bikes, ones with baskets and bikes sporting UK flags.

You can tell some of them are new to biking as they are wobbling a bit!

But everyone is doing well.

I'm not sure if you've ridden a bike before Clare, but I'm fairly sure that bunny tail may get in the way a little...

You may have noticed that there's been a lot of Penny Farthing patter so far today. The reason for that is twofold.

a) I find them amusing.

b) There are literally loads of them out and about in London. Excellent scenes. The two guys in the image above deserve so much credit. Good work lads.

High-end cycling isn't as simple as hopping a bike and pedaling into the sunset - but it doesn't have to be complicated either.

I'm not sure your daughter looks all too keen on that prospect there Joe...

I'm delighted to be able to tell you that the BBC have extended our contract with RideLondon to broadcast the race until 2019.

Catherine Farrow was diagnosed with multiple sclerosis three years ago and this year is taking on her first RideLondon race after being inspired by her husband Jason who took part last year.

"We are delighted to be able to help raise funds for the MS Society and together we can beat MS."
