 Product Description 

1. Genearlly Spec:

PS. V3Ti short for V3 thread integrated, which mean phase wire exit from thread side of motor axle, we plan to replace V3 motor gradually.

2. Dimension Drawing:

Refer to V3 drawing firstly.

For 205 spoke motor, we provide 1 piece Hex Flange Nuts M16*1.5*13, 1 piece Hex Nuts M16*1.5*7, 1 piece 4mm thick Washer as default.

Option 1: Hex Flange Nuts M16*1.5*13 + Hex Nut M16*1.5*7

Option 2: Hex Flange Nuts M16*1.5*13 + 4mm thick Washer

We suggest option 1, if the motor shaft length is not enough, choose option 2 and make sure the washer is installed and tight, otherwise there is a risk of shaft broken.

 Difference between V3/V3I/V3TI 

1. Phase wire exit from thread side, which is easier to mount on bike and it looks better.

2. Phase wire change to integrated one instead of standard loose one, which improved from IP54 to IP65.

3. Add brake spacer as default, which is thinner to avoid scratch phase wire by brake disc.
