So my Vado 4.0 SL went for a 30 mile ride again yesterday and about 12 miles in, the power AGAIN started just cutting off, like the whole bike would shut itself off. It was doing this before, went in for service, presumably was fixed (NOT). It would power back up for 3-5 minutes and shut off again. Numerous times. Finally it powered back up and I had no assist no matter what assist level the bike thought it was giving me. So anyway, I'm contemplating just having them give me a new bike. Diagnostics show motor error but they thought whatever problem there was resolved(?) I dunno. I'll probably get more info on what they actually did the first time it went back, but long story short, they thought it was fine. SO I'VE BEEN WONDERING. I am coming from a Sirrus full carbon frame, and the only thing I'm not crazy about is that the SL is a vibration monster. Most of the time it doesn't make all that much difference. I bike mostly on a rail trail nearby, but the "connector" trail about 2 miles long to the rail trail its all broken concrete and its pretty brutal on that. The whole bikes shakes. No rattles or nothing much "wrong" really except that the whole frame takes all that vibration and sends it up to me. SO MY QUESTION is....would the future shock eliminate that? I.E. maybe I should order a 5.0 instead of a 4.0? I dunno. Not that I'm obsessed or anything. Even with sale pricing its a $1250 difference. WHAT DO YOU THINK? Any ridden them both? Does the carbon fork and future shock help enough to warrant the expense? I actually do like the brushed aluminum color of that model unless there are maintenance reasons that ended up being a bad idea. ANYONE?
