Dyno for EU testing

I am wondering if anyone has a device for measuring the actual power and torque output at the wheel. Seems like it would be an easier thing to make than an electric unicycle.

@EcoDrift has a dyno testing rig that they used to check out a few wheels.  Them Ruskies are always a few steps ahead of the game.  ;)

Also e-wheels.de ?once had?/has a dyno for testing.

@EcoDrift stated in the russian forum that new Kingsongs cannot be tested anymore on a dyno (unfortionately without explaining the reason) and something like new EUCs are strong enough so he won't make any further tests... ?

Car dyno!  I was picturing something a lot smaller that  could be made economically for the more modest power of a EU. Like a wheel with a pulley that turns a modified alternator to provide an adjustable load. I was also surprised the dyno was only being used to test stock EUs. I  figured there must be people out there making modifications that want want to see measurable results.

We might be able to beef up a little something like the dyno made here .. DIY Dyno 800-1500 watt motor .. they spent less than $400 in materials.

Or

for $3500 they make a go-kart scale sub 20hp dyno ... https://www.mittlerbros.com/Chassis-Dyno .. no EUC would need more than 20hp dyno.

or

does anybody live in an area with allot of go-kart racing / riding ??

find someone who already bought the go-kart dyno .. maybe just pay to do the test itself .. just like only pay to test on a car , don't have to build or buy the whole dyno.
