So we find in post
#47 that the real problem is the electric bike issue. 250 mm spokes of the largest diameter will result in higher spoke tensions due to the diameter size. And the over-sized hub only increases the torque applied to the rim and bead seat for the tyre. It isn't the "Ghosts" but the twisting effect from the torque applied to the wheel when using the E-bike function. These bikes are like mopeds in the way they work the tires and wheels. Rapid acceleration will allow a bead to slip and the tube can be twisted inside the casing causing failure. Especially when under-inflated. Just correct me folks but is a 622 rim a 29-er or a 700c rim? As ya know I don't know much about this stuff, but would love to be enlightened. Still drinking as per the recommendation of Three Alarmer, and it is starting to make sense.... Smiles, MH
