Due to the 100% electric drivetrain of the bike, it is exempt from the strict licensing requirements for gasoline powered motorbikes in the larger metropolitan areas such as Shanghai[2] and Beijing.[3] The European version of the Urban S will have CBS in order to meet the EEC type approval legislation.BatteryThe Urban S uses a 99.2 V 90 Ah Li-on Samsung SDI battery and has a range of 125 miles (200 km) city and 75 miles (125 km) highway at 50 mph (80kph). The batteries have a predicted lifespan of 125,000 miles (200,000 km) before reaching a charging capacity of 80% but can still be used after this point with a reduced range. The Urban S can be charged fully using either 220 V for 4 hours or 110 V for 8 hours. Licence ClassThe Urban S comes under the 125cc classification in Europe so can therefore be ridden on an A1[4] licence or a CBT in the UK DrivetrainIt uses a 400A DC wave controller with regenerative braking to increase efficiency. The electric motor is a 19 kW 17" high output hub motor. It is air cooled and brushless. The hub design allows better cooling, a decreased chance of overheating/warping the casing and increases the life span of the unit. External links
