regarding hub motors ( i have a few of them ) .. the voltage needs to be up there to generate the RPM's needed, no gearing, the rotor is the axle... vs the friction wheel setup you have..

But motors typically use 20 amp and 35 amp controllers instead of 50 amp + ... wich results in smaller A/H batteries needed.. it all works itself out the same.. in terms of watts.

the hub motors are alot more quiet than your setup.. that thing is neat.. but loud.

if you could build a plate to support the roller on both sides with heavy duty bearings, and have the motor hanging from the plate, it would be alot easyer on the motor's bearings.... mount the plate to a spring activated lever.. pedal to a starting roll and then go.. don't use the motor for dead stop usage..
