"If anyone has done such a conversion with this motor".
yes, many converted and manufactured bikes run this motor, see Easgen (Denzel). They use the same motor.
User called Skeetab78 sketab778 or something.. can't remember right now; he is converting light motorcycle with this 7.5kw motor. It's in the testing phase.
Another person from Russia is manufacturing own frame (basically motorcycle) to be used with this motor but he plans to add gearbox, few speeds, gearbox is the same as rickshaw trikes use.
There is some guy from (in usa) attached this motor to regular fat bicycle via regular bicycle gears. Insane dynamic.
If you want little bit more powerful than this motor you can approach QS; they got similar but heavier ~1.5kg and longer. They have pulleys if you need; they use it with pulleys, not sprockets and chains.
The motor is sold by Cyclone and Easgen.
Easgen has lathed axle in their motor sold with freewheel which puts on motor axle so your motor won't spin when you realease gas; oh and it is 420 which is good if you want it for motorcycle.
Regarding it's power output. It's up to 10kw, peaks.
Regular controller settings coupled with this motor look like this - 72v 70A battery amps; maybe up to 90A if overpowered.
QS use their motor with up to 20% to 30% more Amps. QS put their motor in scooters and 12'' rim ~120/70 tyre motorcycles/scooters, Monkey bikes. 20Teeth front, 103teeth rear pulleys.
Kilometres per hour.
Speeds, up to 120 in speed gearing.
Speeds up to 70 for torque, offroad.
Bikes weight usually up 70kg with this motor (battery and rest included, without driver).
with 72v battery; motor spins 4500RPM; with flux - 6000RPM;
Therefore regular 1:4, 5:1, 6:1, 7:1 gearing is doable for this motor if mc rim is 14 - 18 inch respectivly, approximately.
Both motors cost ~200usd plus shipping.
Cyclone/Eastgen motor weight 7.2kg
QS motor wight ~8.5kg
Cyclone/Eastgen motors are coupled with Kelly controllers.
QS use with their custom controller worth of ~190usd.
