A standard ride is 60 minutes, and the clock starts from the moment you unlock the bike. For example; 1) Unlock -> You unlock a bike at 8:15am and ride it for 15 minutes, 2) Lock -> You lock the bike at 8:30am while you do a quick 20 minute "*pit stop" to buy a coffee, 3) Unlock -> You return to the bike at 8:50am and ride for another 15 minutes, arriving at your final destination at 9.05am. In total 50 minutes have elapsed since you first unlocked a bike so you are only charged for 1 ride.
* You are only allowed one "pit stop" per 60 minutes.
** Bikes are available to hire 19hrs a day (5AM to Midnight), 7 days a week
