The Specialized Turbo Vado SL 4.0 is super light which means that it is easy to carry up steps or onto public transport. It has a 320Wh battery which is internal and has a range of 80 miles and there is even the option of fitting an extender which will increase this by another 40 miles. It has a rigid aluminium fork which can easily absorb the bumps in the road. There is a Shimano Deore 10 speed drivetrain which makes it easy to go up hills and makes gear changing really smooth. The Tektro HD-R290 hydraulic disc brakes provide safe and consistent stopping power with little effort.
