This year I have my average up to 8.0 mph, with liberal use of throttle up hills. 30 miles, 3 hours 40 minutes. Down from 5 hours 10 minutes the first trip early June. About half the time I use no electricity at all. Usually I start 30 mile trips early May but the bike was stuck in low 2nd speed, 2 mph as I replaced 4 components 8000 and 4000 miles old. Also had zero brake most of May, or else scraping all the way. I limited trips to 8 miles RT until June.
I really don't like going fast most places; the pavement is not up to it. Not with 60+ lb supplies & no suspension. Where the pavement is perfect (the industrial park) is one place where I pedal unpowered.
Rest pulse is down from 80 in April to 72 now. I've lost 5 lb since April. I was really out of shape because I sprained my foot pedaling into a 40 mph wind in March and had to limit force 6 weeks while it healed. No battery in March, it freezes here until mid May.
