My above post was slightly misleading. I am undoubtedly more tired after work for my ride home. However I allow more time for for xc route to work and ride in a very different way. I ride in eco and for a few sections where gradients allow have the motor off. Off road I am enjoying my surroundings and the technical nature of some of the tracks with no interest in higher speeds. Well a bit, there is a steep downhill section with a loose surface which I career down and have glanced at the speed to see well over 20mph, but the motor is off for that bit. For the ride home on the road I want to aim to average 20mph +or- a mile an hour and use the higher standard power setting to get me up steeper hills quicker to keep my average up but inevitably use more battery. I bought my bike to commute to work and back on and needed it be able to cope with my off road route and also be a good road bike for getting home . Inevitably there are compromises. If I just used it off road I would have lower gearing and off road specific tyres run at lower pressures. But overall it manages to fulfill both roles really well. My bike is one month shy of three years old now with 8382 miles covered. I feel like I am starting to get a bit of value now for my initial outlay of £1750.
