Bike sharing is hitting the U.S and the race is heating up with startups raising hundreds of millions of dollars.
They're trying to duplicate the success from overseas without the problems.
Toby Sun and Caen Contee are the co-founders of LimeBike. The company has so far raised $132 million dollars from investors including top Silicon Valley VC Andreessen Horowitz.
SOUNDBITE: TOBY SUN, CEO, LIMEBIKE, (ENGLISH) SAYING:
"I think it's definitely, you know, tougher than it is in China but I see that as a good thing."
SOUNDBITE: CAEN CONTEE, HEAD OF MARKETING AND PARTNERSHIPS, INTERNATIONAL EXPANSION, LIMEBIKE, (ENGLISH) SAYING:
"I think the way we've approached this always is how do we work and collaborate with the city//Ultimately it's creating long term programs. I think the difference is you've seen things that aren't sustainable in other markets."
Limebike is competing with two China bike sharing giants Ofo and Mobike that have already launched in the U.S. Mobike says it's in only five cities so far - moving slowly by design to make sure it's sustainable in the long run.
In some cases it's the cities that keep companies in low gear. San Francisco for example is allowing only two bike share companies to operate. One of them, Jump Bikes got approval for a pilot program of only 250 electric bikes. CEO Ryan Rzepecki says his company has an extra feature to make sure bikes don't get stolen or end up clogging sidewalks.
SOUNDBITE: RYAN RZEPECKI, CEO, JUMP BIKES, (ENGLISH) SAYING:
"So we know which user last used the bike and where they locked it up. If the bike wasn't locked properly we can go to that last user and hold them accountable for that."
And cities across the U.S. hoping to get more Americans out of their cars and on bikes will be sure to watch these pilot programs and their bumps along the way.
