JESUS!!!!! I watched half of that youtube video and had to turn it off. My nerves couldnt take it.
I am also considering taking up cycling(again).
Yes we have been here before and you all gave me some nice advice but after getting a bike that was too big and struggling to find another one I gave up.
I have been looking around and I still have no idea of what bike I should get. I am very very small and I think I will have to get a childs bike

but i'm not sure that these are road worthy

Edit: like this one fro example

Any tips? advice?
When I am cycling, I will need to go from oval to clapham common, its a fiarly simple route isnt it? not too hazardous... how long do you think it should take? 10 mins?
