General Discussion about large electric scooters and motorcycles and other things with no pedals.
Nasty. Maybe put it in a unicycle to save weight? And end the suffering.
This is to express my gratitude to Justin of Grin Technologies for his extraordinary measures to save this forum for the benefit of all.
2 grand for a hubmotor. QS isn't after the Chinese market anymore. I was the first one to use one of their motors back in 2011 and 12, a 50mm wide 273, and I paid $300 plus shipping. The guy bought a different winding of the same motor for his scooter not knowing any better and thinking he'd get more torque. Kv a bit over 18 in a 20" OD wheel fed with 425A from the 20s battery was a beast on my 130lb bike, but the big iron losses from such a high pole count made it run hottest cruising at WOT on the highway. Then I discovered the high efficiency 6 phase hubbies and the QS motor has been collecting dust ever since. If the Chinese would just come out with cheap 200V controllers I'd be in heaven.
