The Viking Evolution provides an assisted range of of up to 30 miles from its powerful 36 Volt 10.4Ah battery. Rather than having a throttle, the motor helps you along when you start to pedal. With a seven speed shimano drivetrain you can still choose a comfortable gear and select the level of motor assistance you require depending on the terrain. Assisted E-bikes are limited to about 15 mph (25kph) and do not require any form of insurance, should you wish the Evolution can be ridden without the battery as a regular bike.
At the heart of the Evolution lies a 250 Watt rear hub motor, the 36 volt battery sits neatly in the rear pannier rack for easy fitting/removal. With a low step over height, the aluminium frame can be quickly folded for easy transportation or storage. Equipped with a comfort saddle, full length mudguards and super bright LED lights this Viking bike is ready for anything, from nipping to the shops, your daily commute or trips in the country. The handle bar module provides battery status information via handy LED's and has a button to adjust the level of assistance.
How is the frame size measured?
Most E-bikes are measured from the centre of the crank to the base of the seat post tube. However, some E-bike manufacturers may measure their bikes differently depending on their style.
