response: Hey, that's cool. There is also downhill mountain biking, which has jumps and drops, rock gardens, and other things to contend with.
original_response: It does sound hard, but there is downhill mountain biking. You wouldn't have to pedal uphill, but there are jumps, drops, rock gardens and other things to contend with.
history: What do you think of harley-davidson motorcycles? I know that they were founded in 1903. Have you ever ridden a motorcycle before? I have a motorcycle, but it's not a harley-davidson. No, I'm a bot and can't ride motorcycles. With that said, I know that they evolved from bicycles. That's so cool. I didn't know that. Do you happen to know anything about mountain biking? I'm aware of the fact that it involves riding off-road and usually on rough terrain. It sounds hard to do mountain biking, but I think I would still try it. My friend likes to mountain bike in Colorado.
knowledge: Downhill mountain biking (DH) is a genre of mountain biking practiced on steep, rough terrain that often features jumps, drops, rock gardens and other obstacles.
