Karnal, what sort of battery does it use ?
In some of the cities there are Lime battery bikes littering the streets. You have to use an Iphone to access and pay to use which unlocks the bike.

Electric bike share from LimeBike. Say hello to Lime-E, the next step in smart mobility. With Lime-E, the new electric-assist bike from LimeBike, your trip across town just got easier. Lime-E's lithium Ion battery helps you ride up to 14.8 mph without breaking a sweat, even uphill!
Unlike previous Australian bike shares, Lime’s bikes are electric, which makes riding them easier and quicker. The company claims they can reach speeds of 24km/h, even with hilly terrain.
Each bike uses a lithium Ion battery that will be recharged every two days. Lime has hired a team of 50 people to monitor the bikes and recharge them.
