The long story short.
My Vado 6.0 is now 3 years and 5 months old since the purchase, and it was built in 2017. The "total system weight" (e-bike, rider, and cargo) in my case approaches the e-bike limit of 130 kg (300 lbs). I often ride really fast in rough terrain. On recent rides, my mates could noticed the wheel became "untrue", I gave the wheel to the mechanic who trued it. Two weeks later the wheel got bent again. I had a serious talk with the mechanic who is an authorized DT Swiss dealer. He said: 'Your rear wheel is really worn out. It has become "plasticized", the spokes are weak, and the rim is clearly bent'.
We started talking. One of the option is to order a new rear wheel matching the Vado 6.0 with Specialized. It is a 622 (29") wheel with outer width of 35 mm and the inner width of 27 mm, and only 28 spokes (it is not too many given the total system weight). The issue is it is not easy for Specialized to find the identical wheel in the inventory. Not sure about the cost. I would gladly pay for it but the 28 spokes is not too many as for a heavy bike and rider for rough terrain.
Another option is to build a new, custom wheel. Alas! That is not easy either!
Don't you think wheel building, especially for e-bikes is a kind of nightmare? Your own experiences you would like to share?

- First, you need a good hub. Ordering a DT Swiss 350, 12x148 mm, IS (6 bolts) mount for disk brake rotor and a freehub for a 11-speed Shimano cassette was the easiest thing. Even the price I got was good!
- Second, I needed the rim. Yes, DT Swiss make a 32-hole, 622 mm nominal, 150 kg system weight, ASTM 4 rated rim of the outer width of 35 mm and of inner width of 25 (not 27!) mm that could be found. Do you think it is easy to actually order such a rim? It is not.
- Then, there are the spokes and the nipples. There are at least 3 different calculators for the spoke length, including the DT Swiss own. Having determined the correct spoke length (and knowing the model from the mechanic) as well as selecting the nipples in advance (!!!), I could start ordering spokes and nipples. What a bad surprise! DT Swiss sells spokes by one hundred pack, and as you need two different lengths, you need as many as two packs for a single wheel! (The cost is growing exponentially...) Sapim sells spokes in smaller quantities. Anyway, you need to become a spoke & nipple expert...
