My Friend's E-Bike

We've gone for a ride so I can appreciate the benefits of an e-bike over normal ones. This one is called a 'gravel bike' which means that, with slightly thicker tyres, you can ride on tracks as well as roads. As you can see it requires an 'app' on your phone in order to operate. Of course it's showing a speed of 0mph at the moment as I'm stationary for the purposes of taking the photo!
