It's no secret Boise has some amazing outdoor trails.
"You could ride almost through the state of idaho from our backdoor if you want," said co-founder of BoiseTrails.com Kirk Cheney
But some bikers want more room and more of a challenge.
"One knock on Boise's trails is that a lot of them are the same," said Cheny.
Most of the trails aren't as difficult as some riders would like, and they keep getting more crowded. Treasure valley is growing fast and the BLM, along with the City of Boise and private land owners are proposing to expand nearly 15 miles of trails.
"Anyone that goes out on the trails on the weekends or when its not the weekends, there's just nowhere to park and we're trying to disperse out," said outdoor recreation planner of BLM David Drahein.
In the past, the public has voted for multi-use trails that everyone, like hikers and mountain bikers, can use together. One new proposed trail would be a flow trail, which is an entirely down-hill trail for mountain bikers only.
"The bikes will use it to go down the hill and we won't have those collisions of hikers and equestrian going up the hill when the bikers are going downhill," said Drahein.
Bikers like Cheney hope others share his enthusiasm for these new trials.
"It's like the adrenaline of a rollercoaster but on your bike and it's more fun honestly because it's not so scripted, like you're in control," said Cheney.
The BLM is still working through the plans for the east foothills and other possible trails.
