I have to say that my bike down shifts much easier since the cable was replaced and the cable guard shortened. There is still a good amount of resistance but carpel tunnel inducing pressure is no longer required. I'm sure all the pressure required to shift is what broke those parts.
Damn ... what's the story behind that?
Just riding the bike and noticed it when I got back.
The post does goes past the weld. I can't get the seat post out of the broken bike. I talked to leili and they sent the photos to the frame builders. The said it's because the seat post is too high so it's my fault, see photo of the black bike they sent me. As you can see in my photo, I only have it up like 2.5 inches (only a 30 inch inseam). They offered to send me a new frame but I have to pay for shipping plus it won't arrive until summer.Is it possible that your seat post was shortened because a longer post would not go past the ( very poor ) welds? That's what it looks like to me.
With this comparison pic I see the problem. Due to the lower enlarged tube the extra lower length of post does nothing to stop the upper part of the post from moving. This is going to happen to a lot of these bikes.
I had a feeling when buying these bikes that would be a weak spot. I am going to get a professional welders opinion on it. Also it doesnt seem to make a tight fit on the seat post like my normal bikes do.
There are minimum insertion marks on the standard seatpost and yours is well within that limit. My Suntour NCX suspension seatpost requires a sleeve shim that is 4" long and that shim helps reinforce the area. I recall some frame building photos that show the seatpost tube going an inch or so into the box below that contains the motor controller. As you can see from the photo, the 400mm suntour seatpost is considerably longer than the stock seatpost. Although below minimum insertion mark, my seat is much higher than yours and that creates more leverage on this area. After 1000 miles, mine seems very solid.
While not pretty, the weld does not appear to have failed. Unless the seat tube extends and is supported in the boxed section of the frame, I think Reed may be on to something. It will be interesting to see where this all goes. Could be a serious design defect.
That's rough. You just made me glad I ordered from Biktrix. If I have the same issue at least their shipping time is quicker. .
Photos?
But then my bike is not from Leili, it is from Steamoon.
Yes, it's not a different version of the MD1000 frame, it's a completely different model and frame design on yours.
