I just joined the forum after spending quite a bit of time reading the many informative posts. I need some experienced advice and insights! I am a very long time cyclist (72 yrs young now), in very decent shape but getting older. I live in San Diego and love to ride. I have a Marin mountain bike circa 1992 which I still ride mostly on streets now. No problem riding 25 miles or so at about a 15 mph clip. Exercise rides at HIIT of 1/4 mile at 20 mph followed by 1/4 mile 15 mph pace. Do about 10 to 15 of those repeats. I'm looking at Specialized Vado 4.0 SL and Turbo Vado 4.0/5.0 bikes. I would like to be able to ride 30 to 45 miles with single charge from my inland home (elevation 1000 ft to the coast and back. Road conditions are fairly smooth with bike paths; sometimes some mildly rough roads. Based on forum member experiences I was hoping to get some insights as to recommendations. I thank you in advance. Look forward to comments.
