A steep old hill for a veteran and no doubt, the postcard claims it is however a genuine image. I'd have a guess at the bike being a Rover c1914 fitted with an Armstrong hub gear. Here's the text from the card:
642 Motor Cycling in Lakeland
"An awkward hill"
This card is an actual photograph by G. P. Abraham, Ltd.
The card was posted in 1924.
