I modified a Harbor Freight dolly to accomodate the wide 240 tire. The only offerings for a bike like ours would either only accomodate a 200 series tire (and they call it a chopper dolly!!) for $129 through discountramps.com, which,BTW, is just a longer Harbor Freight dolly, or the BikersPal dolly from Canada at $700 (US dollars) plus $45 shipping, which will accommodate a 240 tire. I had to purchase 2 Harbor Freight dollies at $70 each. I had one section cut down the center and a 4 inch piece of 1/8 in steel welded in. I had that reinforced underneath across the now 12 inch span in 3 places with 1/4 inch steel. I cut a 20 inch long piece of one section that included the welded-in caster mounts to give both extra length and now additional casters in the middle section for more support. I also had to make a longer rod for the leverage wedge lift at the end of the now 12 inch wide section(since it was originally designed to be for an 8 inch dolly). The total length is now approx 96 inches with 94 inches of usable length. I spent a total of $340, $140 for the dollies and $200 for the welding/materials. If I had done the welding in one trip I could have saved $50 more. I have seen one on this forum made using wood with a Harbor Freight wheel dock, but I prefer the lifts at the end of this unit to keep the unit from tipping and from rolling when loading and unloading. Also, I already owned one Harbor Freight dolly purchased years ago, so I only had to lay out $270.
