Not sure what bike frame you are putting the kit on but (safety warning) make sure you use some nice torque arms or plates to stop the axle chewing out the dropouts or snapping them off . More so in a aluminium frame. (particularly if its a front wheel motor).
The geared hub I put on my wifes folding bike ripped the entire rear dropout off the bike (using real short torque arms in a aluminium frame) Mind you it was being fed with over 3000w
two 16mm thick SS machined torque plates got it back on the road.
Once you feel that smooth quiet instantaneous torque you will have the EV grin
