You have solved one of my biggest problems, thanks a million. John

Im not sure, never really thought about making them to sell. it cost about $80 to $100 to make though.

ok thanks man

$80-100? You must be using some expensive casters. The lumber is pretty cheap on that. Doing a quick search on HomeDepot.com: $7.08 -- 8 ft 2x10 $3.47 -- 8 ft 2x4 (probably need 3 of them) That brings it up to $17.49... Maybe add another $1-2 for the 4 bolts and nuts, so let's say $19.49 just to be safe... The smallest caster that I could find for sale at Harbor Freight was around $6 each and it was a 4" caster with a 330 lb load rating. So, for 4 of them, you would have a 1320 lb capacity motorcycle dolly. That would be enough for even large touring bikes. So that would bring it up to $43.49 in just the parts. The design in this video though looks like it uses smaller casters though. Probably because the bike is lighter than what I would build it to hold. You could probably save a bit of money by buying two of the 18"x12" Hardwood Moving Dollies from Harbor Freight for $10.99 each and adapting the platform to stretch across both of them. That would give you a 2000 lb capacity platform. Or just buy one of them and use the casters from it instead of buying the separate casters that I mentioned above. So, I would estimate that someone should be able to do it for around $50, at least around here. If I was building it, I would probably go with a 2x12 though since my bike is a bit heavier and wider.
