How to recognize your bottom bracket?<\/h2>\n<\/div>\n
<\/div>\n<\/div>
<\/div><\/div><\/div><\/div><\/div><\/div>

As described in the “compatible” tab, if your frame does not have ISCG mounting studs<\/strong> directly on the frame, you will need to install an adapter to attach the LIFT-MTB mid drive motor<\/strong> to your frame.<\/p>\n

To do so, you just need to identify the bottom bracket model equipped on your bike.<\/p>\n

Below you will find a simple guide<\/strong> to help youidentify the standard bottom bracket you have<\/strong>.<\/p>\n

NOTE: We also recommend that you read the “COMPATIBLE?” page for more information by clicking on the button below.<\/p>\n<\/div>

There are two main families of bottom bracket:<\/h3>\n<\/div>\n

Steps to differentiate bottom brackets.<\/strong><\/h2>\n<\/div>\n

1) FRAME WITH EXTERNAL BOTTOM BRACKET, SCREWED TYPE BSA<\/h3>\n<\/div>

Specificities:<\/strong><\/h4>\n

In this case, there is a thread of 34.5mm inside the frame<\/strong> which allows to screw<\/strong> aluminum cups (in red on the picture) in which are placed bearings.<\/p>\n

The bottom bracket axle will then slide into these bearings<\/strong>.<\/p>\n<\/div><\/div><\/div>

\"Bottom<\/span><\/div><\/div><\/div>

To recognize this standard:<\/strong><\/h4>\n

We can see, exceed from each side the cups<\/strong> with the typical imprint of the lugs to put the loosening tool.<\/p>\n

Opposite is a top view which allows to distinguish the cup with the lugs, and the key which allows to dismantle the cups with the bearings.<\/p>\n<\/div><\/div><\/div>
