I originally thought I would be a throttle only chap, but within 50 miles I was on pedelec 90% of the time. I had underestimated the childhood instilled 'urge to pedal'.
I mostly go everywhere on max assist and dont use any throttle. Where I do prefer throttle is perhaps on seafront promenades and cycle paths that are a bit crowded, it just gives more finite control, and adds to the magic sensation of floating along the seafront at a relaxed 10 mph and taking the bracing sea air. It is somehow more graceful and relaxing than pedalling. I also use the throttle when I've had a few, umm, refreshments, and I'm so grateful, it just takes me home!
