How true and centered are BMS Battery wheels?

[Fordulike]

I know a few of you have bought complete wheel and hubs from BMS Battery.
How true and centered were they when they arrived?

I was very pleasantly surprised by mine I must say, perfectly true and centered and has remained so through nearly six months of inner city London riding. Having thought that I would order the wheel as part of a kit and then probably take the hub motor to a wheelbuilder to get new spokes and rims added to the motor it hasn't proved at all necessary, I'm very pleased with it.

Thanks rh1968, sounds good so far, anyone else?

Mine has a bit of a wobble in it. Nothing to be concerned about, but it's annoying to have even a slight kink in a brand new rim.

The other issue I found was that it should have been dished. The spoke mounting points on the hub are significantly off to one side, so to ensure a centralised rim relative to the forks the spoke angle shouldn't be equal on each side. They hadn't taken this into account so I need to get this done at my local bike shop to centralise the rim.

This is a front BMP hub. In short, there isn't anything really wrong with it as such, they just lack attention to detail.

Sorry to sound a bit thick, but can someone explain in layman's terms, maybe with a diagram, what this means
Does it affect the effectiveness of V-brakes?

OK I'll have a bash: if you look at a wheel end on, rather than from the side, the spokes make an isosceles triangle with the rim at the apex and the hub flanges (where the spokes attach to the hub) are the two base points, yes? Now, if you have to stretch out one side of the hub, for example to accommodate a disc brake or a rear cassette, the triangle will be longer on one side than the other, so you have to have shorter, tighter spokes on the short side to keep the wheel true. That's what dishing is, so called because if you lay the wheel on its side it will have the shape of a dish or bowl, with one side protruding more than the other. Hope that makes some sense!

If you want to use V-brakes and are ordering a front wheel (i.e. without a disc brake rotor) then dishing or the lack of it doesn't come into play. However a kink in the wheel definitely would affect the smooth running of your brakes and ultimately the integrity of the wheel, if you get a wheel with a kink in it get it to the bike shop and get it trued before use (for practical purposes sending stuff back to BMS for replacement isn't really worth it due to high postage costs).

Mine was very true but not nearly tight enough. I have since rebuilt the wheel and trued to a correct stength to take the additional weight over the rear wheel and me.

Most the spokes ended up becoming loose unfortuantly. But I can let thme off. It was jsut someonthing extra for me to learn with electric bikes and cycles in general.

Now I've done it, I will never have anotherone build or true my wheels ever again.
