I have the White E-mate; not so sexy but nearly as powerful and the bigger battery gives me easily 50 miles range at level 2-3 (out of 5)
It was the range that sold it to me, as I like to cycle for 2-3 hours in the countryside close to my home. I can 100% recommend the Oxygen bikes for build quality, and the importers, SYEB are a very friendly and helpful lot. I find that the E-mate with it's main battery operated lights, good carrier for panniers and decent mud guards makes commuting very comfortable. I would strongly recommend upgrading to reinforced tyres (Shwalbe city-jets in this case) and slime tubes; I had a "tyre off" blow out on the back and carrying a 24kg e-bike 3 miles to the nearest bike shop is not my idea of fun.
