Thanks for the helpful reply will look into these bikes I need to find a retailer who will accept my cycle to work scheme that stick these. Thanks againYou'll want a bike that is a good hill climber to get a rider of your weight up a 1 in 5 hill. The Coyote Edge 650B looks to have one of the lower powered 120mm hub motors and as such will have much poorer climbing ability than a bike such as the Woosh Big Bear that has the 180mm BPM motor. I am the owner of a Woosh Big Bear and it is a very strong hill climber. It is within your budget also. Some other bikes with an equivalent motor include all the Ezee bikes, and the Kudos Arriba and Kudos Tornado which are within your budget also.
You may also be interested in a crank drive bike such as the Woosh Krieger. These have the motor near the bottom bracket, and have better hill climbing ability that hub drive bikes because the motor propels the chain and can use the chain in low gears to provide higher torque at lower speeds. However, crank drive bikes come with significant drawbacks, and are often less fun to ride as you always need to be conscious of being in the correct gear at any one moment in time.
