Like many on here I got an e-bike to get fit in my older years (late 60's), my part of Derbyshire is like living in a large egg box non stop hills. I was advised to start gently, and gradually expand my mileage which I've done now up to 7-10 miles per day. A few days ago after four & half miles I decided it was time to turn back just as many hills on the return journey however their was a particularly large hill that I've not been up before so I went for it ( mistake ) about one third from the top I was knackered, but being a stubborn fool I kept going & made it to the top. The journey home was a nightmare, and I was so exhausted I felt really ill for some hours. So guys & gals know your limit if your on older returning cyclist like me, atb, Mike.
