No matter how popular scooters are in certain places and how enjoyable they are to ride, the industry is going to be dogged by critics, at least for a while, for four main reasons:
Still, for those who have jumped on board the trend, there's a certain sense of inevitability about its ultimate success. In downtown San Francisco, where traffic often brings cars to a standstill and a grid of one-way streets can turn a half mile car ride into a mile and a half, scooters provide the perfect mode of transit when walking isn't an option.
"It's not going to be the use case of how do I get to work in the morning?" says Chris Nakutis Taylor, who spent five years at Uber and was hired to run Ofo's North America business in October. "It's the case of how do I get to that burger shop for only $1?"
People who work downtown in cities of a few hundred thousand people may be a mile or two from their lunch spot. In the summer months it's too hot and takes too long to walk. Public transit is often slow or unreliable, an Uber ride is more expensive and could get you stuck in traffic and driving may be a nuisance because of parking.
Taylor used the tech industry's favorite sports metaphor in saying the market is "still in the first pitch of the first inning." He looks at cities in states like Indiana, where he was once an Uber general manager, and sees an abundance of opportunity.
He also said that if you're getting the business right, spending a couple hundred dollars on a vehicle that gets 20 rides a day (in the best markets) for $1 to $3 a ride, it doesn't take that long for each one to turn profitable.
"Transportation in cities is a big problem not solved completely by ride share and even autonomous cars," said Alexis Ohanian, the Reddit co-founder who is now a venture investor at Initialized Capital. Scooters are "fun and frictionless to ride."
Ohanian's firm invested in Skip, which currently operates in Washington, D.C. In the true spirit of the e-scooter market, where participants are simultaneously allies and bitter rivals, Skip CEO Sanjay Dastoor told Business Insider last week that his company is the only one "without a cease and desist order."
Vivek Ladsariya, a partner at SineWave Ventures, invested in Jump before the Uber deal. He believes e-scooter ventures can prove a mainstream success. But he's skeptical of bike and scooter companies that have reeled in huge piles of cash before getting a clear view on how the economics will work and where they can operate.
"All the problems that scooters face in cities still need to be figured out," he said.
To Ofo's Taylor, the arguments about round sizes and valuations sound a lot like what Uber heard early on from the naysayers, who were shocked when the ride-hailing company was commanding even a $1 billion price tag. Its most recent reported valuation is $62 billion.
The key, Taylor said, is moving beyond the coastal hubs and proving that sharing bikes and scooters is going to be an accepted model for transportation in every city where last-mile options make sense.
"Uber didn't become a $60 billion company by winning on the coasts," he said. "If you don't win Main Street in Anytown, USA, you're going to be relegated to the edges."
