Freewheel on a 10 inches hub motor 3000W

[enabor]

Hi,

I'm ordering this kit http://www.hs-escooter.com/sdp/1012...60V_72V_10inch_Hub_Motor_with_Disc_brake.html and asked for a freewheel. The seller came back to me today saying that the shaft of the motor is too big so it is impossible to mount a freewheel on it.

Did anybody here have the same issue here ? What type of solution did you find ?

Another question : my freewheel is on the LEFT side of the wheel, but I saw that other scotter have it on the RIGHT side. Is it easy to flip the freewheel axis (the one near the pedals) if the freewheel can you be put on the right side ?

Thank you for your advices !

What kind of vehicle is this going on? Where are you situated?

It is for my e-moped. I'm located in Montreal, Canada.

I wish I had an easy solution, I can't think of anything. Maybe someone else can come up with an idea but the motor you bought does not have the threaded part on the center of the end cap to accept a freewheel sprocket. Are you replacing the original motor of your e-moped? Did it have a freewheel sprocket on it? Can the end cap with the freewheel sprocket of the old motor fit on the new motor?

I'm not quite sure I understand how your e-moped is made actually, you say the freewheel is on the left of the motor?

My scooter is looking very similar to this one http://www.daymak.com/images/scooter/lonestar-silver-left.jpg but the brand is chineese (zongshen jaguar). Yes, I'm replacing the original motor and I still have the freewheel sprocket on it.
I'm currently in communication with Vito from QS motor and asking if it is possible to mount a freewheel on his 10 inches hub motor https://wholesaler.alibaba.com/product-detail/QS-10inch-3000W-205-50H-E_60272547345.html (no answer for now). Yes the freewheel is on the left side of the scooter, I can make a picture of it if you need.

Pictures are worth a thousand words. The only solution I can think of is to take the end cap off the new motor, the one you want the Freewheel Sprocket to be on and bring it with your FS to a machine shop and have them machine threads to screw the freewheel sprocket on the end cap. Now you say your moped has the chain on the left side, so the brake rotor is on the right side? I guess you can just flip the motor around but you have to be able to enter the programming of your controller to reverse the rotation of the motor.

EDIT: Nope! Forget what I said above about machining the end cap, I took the time to look at the CAD drawings of that motor and what Vito said about the motor shaft being too big is correct. If you have a freewheel sprocket like the one I had on my original 500W motor, the threads are something like M35X1.0. So you would need to machine the middle part of the end cap down to 35 mm. That shaft is 25 mm thick so there is no room because of the oil seal which probably has an outside diameter well above 35 mm.
