According to practical data from strava average energy consumption on moderately hilly routes (6-7%) is 7-8 wh/km, on those with light hills 3% - 4-5 wh/km; this means that in the 1st case 470 Wh battery shoild last 67 km, in the 2nd - 106 km! On practice however this battery is hardly enough on road of 1st kind for 25-30 km. Also on 7% uphill energy consumption is 18 wh/km and if all journey is such uphill such battery should last 26 km.

As to the power needed to go uphill. Again according to data from strava on 6% uphill for 12 km/h it takes 240 w; this means that even 250 w motor for any uphills is quite enough. On practice one person told me that with his 350w geared motor wheel working at full power (which could be much more than that) he has to turn pedals; other users said that going uphill took 500-700-1000 w!
