bike

Instant karma came to collect, and she wasn't ready for it. 

This dude thought he was about to get his bike into his pickup, but the ramp had another idea.

"A random guy showed up to the trails that I ride at and tried to jump them after watching us ride them. This was his second attempt and this is the first jump in the set."

Who says you don't need arms to bike? Actually, no one says that. But the sport of bike boxing is just getting started. 

During the Dubai tour, rider Andrey Grivko was disqualified after he punched fellow-rider Marcel Kittle in the head in the middle of the race. That's one way to get this done. Or you could just ride a little faster. 

As you can see from the picture, he cracked him wide open, but it didn't really help in the long run. 

At first Marcel seemed rightfully peeved:

I won't accept an apology for this. That has nothing to do with cycling. What Grivko did is a shame for our beautiful sport. pic.twitter.com/vvMN5LzQN0

But then had a pretty good sense of humor about it. What a guy. 

And I just googled Grivko and it said he is 70kg. Dude, know your limits!! pic.twitter.com/JnhYQk58vt
