Blimey, What a cool entry into biking........
You have already demonstrated you know how to play it safe so good on you, I think you have picked the perfect bike for your introduction. I jumped on one yesterday for the first time and bought it there and then after a 20 minute test ride. The riding position is nice and high and you are visible to others as well, also very easy to hustle along and change direction quickly with a good dose of power to assist where needed.
I find the bike is a great deal of fun, and only wish I had bought it a month ago before my trip to Belgium,Luxembourg and Germany which I did on my more powerful but much duller touring bike.
Ride safe
Al.
