Ribelle and EGO are pretty much the same power train,ego is tweaked a bit higher. I have a racing ego, tweaked even higher, MUCH higher, I have done back to back to back to back sessions on the track, 20 minutes or so each, come in, charge up at 35 amps (the most a 50 amp feed will let me do) right back out, and never hit yellow with it. hitting speeds 135 occasionally 140 on the track. Maybe if it was 98 degrees out it'd see it, as I DO see yellow sometimes on my Ribelle when Ive been romping it hard on the highway, but were talking being stupid, triple digits for 5 or 6 minutes straight.
The charging is nice because you can use simple house current from 115 ac, 240 ac, or the fast charge CCS1 to charge it so you have plenty of ways To charge it, you really won't be stranded anywhere, just may take a bit to charge on 115volts.
What do you want it for. It's a fun bike but, what is your use intent for it.
It IS a bit heavy overall, and top heavy so lower speeds, like under 6 mph you CAN get into trouble very fast if you say, take a fairly sharp turn or tap the front brake. once you are going faster than this, she handles very well.
If I am doing 40 - 50 mph or so, some 35 mph rural, some 55 - 60 mph light highway mix, I can get about 200 miles per charge. If I am doing 75 to 80 on the highway, I can get around 100 miles per charge, (trust me, you want to take a bit of a rest after 100 miles) if Im doing faster, it runs down quicker. WOT will eat a battery in about 30 miles.
The upright seating position is a lot nicer than the aggressiveness of the EGO for casual riding.
