Look at the Pro rider bikes on eBay. I have had a tourer since June and done 800 miles now, I am 140 kg and 6' 2" . All on country lanes, some quite rough. Get about 25 to 30 miles a charge on undulating terrain. I get by on lower assist with medium on steeper inclines. Only trouble has been 5 broken rear spokes over a couple of weeks at 500m to 550m but they soon posted me replacements and l think it was a maintenance issue as I set to and tightened up the spokes and took out a bit of a wobble and it has been fine now to 800m. If you only need the bike for 12 months the warranty will see you through. I have the tourer but they all look to have the same electrics. Under £600.
