CHARLOTTE -- The number of bikes on Charlotte streets is growing.

At least two new bike share companies, LimeBike and Spin, have recently started.

Riders can find available bikes on the company's cellular app. They then scan the QR code on the bike which unlocks it.

The big difference between the bikes and Charlotte's veteran bike share, B-cycle, is that you don't need a docking station.

"I don't see us in competition for the same people. I think there are people who are going to benefit from them and there are going to be people who benefit from Charlotte B-cycle," said B-cycle Executive Director Dianna Ward.

B-cycle said its good for people who rely on a bike being available in the same spot everyday.

LimeBike and Spin charge a dollar for every 30 minutes.

B-cycle charges $8 for a one day pass.
