In 2018 the the first bikes will be “rolled out” and the rest comes 2019. In total there will be 5,000 electric bikes, compared to todays 1,200 leg powered bikes.
A 1-year subscription to the bike-sharing scheme will cost 33 USD.
"The way it will work is that when you register, you are given a small battery which you can charge at home. If you don’t want to use the battery, you just use the bikes like a normal bike, but if you want an electric one, you connect the battery, which is included in the normal season ticket price."
