Hi all. Reached a bit of a crossroad in my life. 56 years old ex Firefighter who was fit as hell done loads of cycling in my time including the Milk Race. Gone to seed now, 17 stone, bulging disc and anuler tear in my back, asthmatic and on high blood pressure meds. Apart from that I'm fine lol. Looking to get an ebike to go to work on to get a bit fitter and loose weight. Journey is 8 miles each way mostly flat. I've been looking around at bikes sub 2k. Cube Reaction, NCM Moscow Plus and Woosh Gran Camino. I know the legal limit is 15mph but would like to be able to do take the limit off to do around 20 ish. Most of my trip is in the sticks. Any help in choice/advice would be most welcome. Thanks all.
