The noise in the EGO / Cyclone motors comes from the planetary gearbox attached to the motor itself, you can't get around it...
Belt drives aren't totally silent either, my Norco's 15mm HTD belt sounded like an old skool supercharger
Having had a 2000w peak cyclone setup and now a Clyte HT hub running 5500w peaks, i can say the only time i truly miss the Cyclone is when i see a massively steep dirt track hill i'd like to climb, the type of hill that is a slow crawl up in 1st gear and a balance of controlling wheel spin vs looping out the front end. The Cyclones will climb grades like that with ease if you gear them correctly. Taking a HT up a climb like that would kill the controller very quickly indeed....
Speed wise the Cyclone (12s lipo) topped out at about 60kph in 9th gear and the HT (20s lipo) about 58kph both on flat ground (both 26" rims). Both will heat up after several kms with too much WOT. Both love
to pop wheelies
The HT is damn quiet and i like that, the Cyclone is like a coffee grinder on steriods
