CS - This bike is a "Time Machine" that literally saved me from cycling depression, after I was "run over" by cancer. It's so much fun to ride and go fast again.
Some background on me, I'm 61 years old, been riding for 21 yrs with a group of hard core roadies in SW Alabama (no commuting for me because I work from home). We typically average 22 mph and do 60-70+ miles on the weekends. 4 years ago I got prostate cancer and had surgery. Last year it came back, so I had to get radiation and hormone therapy. Needless to say for the last 4 years I've been riding 10-15 miles on flats at 14-16 mph, no more group rides, just me alone.
So I begin researching eRoad Bikes and come up with the only two Class 3 (28 mph) bikes in the USA, Giant ($4,500 - 40lbs) and Specialized ($9,000 - 27lbs). The others cut out at 20 mph which is no good to a roadie, you easily do that on the flats and then you're just pulling an anchor. A buddy and I borrowed the two bikes and rode 15 miles out on a hilly course, then swapped bikes and rode back. The Giant was +2x stronger than the SPZ even though it weights 13 lbs more. Weight is irrelevant on the Giant, because it has 80nm of torque and SPZ only has 35nm. It's a tremendous difference, I like feeling the torgue when I need it, especially at the end of the ride when I switch to 2nd gear. I typically stay in 1st gear all the time because the battery life is eaten up when you go into 2,3,4 or 5th. I'll comment on gearing, battery life and price next, but this is probably getting too wordy already sorry.
