While I am totally good with my Vado SL (Redshift ShockStop front/rear, the stock
Specialized saddle), there was something wrong with my Vado 6.0 after the e-bike rebuild & upgrade. I had sore butt after long rides, something what was not happening before the turning my Vado 5.0 into 6.0! First of all, my brother (who was together with me on one of my recent rides) noticed the Kinekt 2.1 springs must have been not properly preloaded, so the saddle was always in the "compressed" position because of my weight, and it did not work as a suspension. As my Vado is kept in the storage and I only use it on some weekend rides, I did not spot it immediately.
This is the perfect setup for me. Regarding the saddle angle, I feel no stress either in the perineal area or on the buttocks. The preload position "3" on the Kinekt 2.1 with the gray spring is enough to avoid pedal-bob but the suspension works properly on road bumps. It is noteworthy I tested that setup in winter trousers with no chamois! (The saddle is Specialized Phenom Expert).
I need to mention the new 420 mm Kinekt 2.1 suspension was provided by Specialized free as a part of the warranty service because they could only find the replacement frame with S, the size M being the original. The Spec guys looked carefully into the e-bike geometry, and found out the only significant change was the seat-tube shorter by 80 mm, and the reach was shortened by just -8 mm (the saddle setback compensates for that).
Regarding the preload on the Suntour Mobie suspension fork, I was trying the soft and firm preload position to find out the firmer preload was appropriate in my case (I am a pretty heavy person, and I ride my Vados in forward position, which balances my weight between my butt and arms). I was riding bumpy segments of a local gravel road for several times to make sure.
This part of the gravel road was mild compared to what I experienced before!
Riding this cracked and potty asphalt segment was an instant reward for me for the adjustments done! I was zooming it at 36 km/h (22.4 mph) and enjoyed the smoothness and silence of the ride!
Now, I'm waiting for a new, strong rear wheel made with DT Swiss components (I should receive it this week). The next upgrade will be replacing the derailleur and cassette with the Shimano M5100 components, 11-speed. The derailleur there has a very long cage, and the cassette is 11-51T (!!!) While it is of no meaning here in the plains, it will be important for my future holiday mountain road rides. Replacing the chainring with the 38T steel one I own will put me on par with my brother riding an e-MTB with the same gearing, only 12-speed!
