Boris Biking... But Not Like You've Ever Seen It Before
These dudes are doing trials on Boris Bikes
This looks insane. Two dudes doing trials-bike stunts around London on Boris Bikes? Nutters!
Closer inspection reveals that the bikes are in fact just customised to look like Boris Bikes - the real things weigh about as much as a Sherman tank and would be nigh-on impossible to manoeuvre like this - but it's still bloody impressive.
The video, which also includes free-running, was produced as a promo for a new app called Fightme, which encourages people to "join in challenges and create their own".
It sounds interesting, though I have to say this is one challenge I won't be taking up...
