    I need a wheel truing stand that accepts 190mm hubs.

    My hub motors have 170 and 190mm dropouts. Park Tool sells a wheel truing stand that accommodates up to 175mm hubs (https://www.amazon.com/Park-Tool-Pro...l+truing+stand, but nobody sells and affordable wheel truing stand that accepts a 190mm hub. My rims are 82-100mm wide.

    This German company sells one, but it is very expensive at approx. $1,500.00: http://www.pklie.de/truing_stand.html.

    I have already done a pretty extensive Google search and seen that others have tried the following:
    (1) Make your own.
    (2) Use a motorcycle wheel truing stand.
    (3) Modify a bicycle truing stand to accept wider hubs.

    My arguments against these solutions are as follows:
    (1) I might not have the time and skill to do this, and I prefer to buy my tools ready for service.
    (2) I like to use the right tool for the job, specifically a bicycle truing stand for a bicycle wheel.
    (3) I have seen these mods and they are only able to support the weight on one side (like a Lefty shock). My motor weighs 25 lbs, and I need that weight to be supported on both sides of the truing stand.

      I thought I would give you my urban hillbilly option. Sitting out in the garage, with a box fan blowing, and radio playing. I could spin spokes all night,

        I just built a set of wheels with the park ts2.2 truing stand with the extension adapters. It's not as ideal as a wider stand, but it wasn't bad either.

          I would build one using Misumi aluminum rails, which are like 8020 rails but better service and lower cost. Lay out a design and they'll cut the parts, then you just bolt it together. Like these: http://us.misumi-ec.com/vona2/mech/M...0/M1501010000/

            I do not know if you received a good answer to a good truing stand but I built one using these instructions on mountainbikelife.com. dyi- trying stand. I modified it to accommodate large hub motor. You can go as big as you want. Here are a few pics. I mounted it to a piece of plywood that has different mounting holes for different size hubs.

              That is a nice stand!

              I ended up buying these Park Tool products: http://www.parktool.com/product/prof...g-stand-ts-2-2, http://www.parktool.com/product/upri...tors-ts-2ext-2 and then this for my thru axle hubs: http://www.parktool.com/product/thru...-stands-ts-2ta.

                Spin doctor for around $60.
                Remove bolts and rotate arms.
                Might need to make tabs for outside of rim cradle for truing; but easy enough to do if you remove original dials.

                  Park Tool has since come out with this very extreme $372 http://www.parktool.com/product/prof...ing-stand-ts-4, but my Park Tool TS-2.2 with the attachments listed in Post #7 of this thread has allowed me to do everything, including 190mm hubs as well as thru-axles.

                  This newest truing stand accommodates hubs up to 215mm!
