I've got just over 500 miles on it, and confess to peddling less and less. But it really depends on mood and mission. Got my first bike in '64 and even way back then I really wanted a motor with a twist grip that would just go. So this ebike really is an old dream come true.
When I first built the thing my thinking was to have a motor assist my peddling. But now, I tend to assist the motor and sometimes just get lazy. I honestly don't feel as athletic as once upon a time.
From a stop I like to peddle hard in a middle gear and quickly shift up to the big gear on the crank. Along with the motor, that gives very good acceleration. 0 to 15 in nothing flat. If I get on it hard, I'll lighten up the front wheel and get some satisfying chirps out of the front tire. Then I'll likely back off the pedals. Working in short bursts suits my personality and physiology.
If it's a trip of a few miles to grocery and back, I tend to peddle less than if it's a longer trip and am going for distance -- peddling can make a big difference. Also, now that it's getting colder I'll probly be peddling more and more. A month ago the temp was in the 90s and when I showed up, folks were wondering how I was so cool and calm and I just smiled.
