Check the compatibility of a bike to turn it into a VAE with the Crankset Engine Kit

The most frequently asked question concerns the compatibility of a bike with our system:


The LIFT-MTB system is suitable for all practices :


- Compatible for  All mountain use (AM).
- Compatible for cross country use (XC).
- Compatible for enduro use (EN).
- Compatible for downhill use (DH).
- Compatible with Tandem

THERE ARE 3 MAIN PARAMETERS TO TAKE INTO ACCOUNT to check the compatibility of your bike:

1- Check your Frame designs with mid drive motors...

electric kit bike's frame design

Many frames designs could be compatible with our electric motor for bike but more your frame offers of clearance between the lower tube and the ground, the more you will decrease the risk of impact.


Between a frame which offers an excellent release and a frame where the release is not sufficient, there is many possible positions for the mid drive motor kit.


In certain cases, the assembly is possible but not necessarily ideal keeps of it for the ground.


A very angled lower tube is generally needed so that the system is compatible not at all.


Below, some photos to illustrate the thing and allow you to have a good idea on the compatibility of your frame with regard to the electric motor for bike LIFT-MTB.


You can also read the page about the e-bike ground clearence with DIY electric bike kit

you must choose between two versions :

You can choose the outside version for our mid drive motor, or the inside version for mid drive motor .

Easy compatibility Test.

You can choose the model compatible with your frame with compatibilty test under.

easy compatibility test

 This is a easy procedure to make a cardboard model of the LIFT-MTB electric motor for bike , and for check if the système is compatible with your frame.
You must have few pieces of cardboard, felt, compass, meter, tape and scissors, you are ready!

Download and print A4 model for download below, then perform the cardboard model.

Once done, you are left only to present the model on your bike to confirm compatibility with your frame.

It is generally considered so if the system is at the lowest parallel to the ground it's OK.

Below, there is more risk to touch the ground, even if according to your riding practice, this can be more or less disabling but that's for you to judge!

Sure, this may seem a bit simplistic concept but questions about the compatibility being the most recurrent, it is currently the most economical and most effective solution we found to bring you an answer.

-2- Check if the frame have ISCG tabs.

-2- Check the presence of the ISCG

 The LIFT-MTB electric motor bike system is generaly fixed on the 3 ISCG tab's for chaine guard of your frame.

ISCG tab's are holes  in your frame, around the bottom bracket (in red on the photo).


You have to control the presence of these 3 holes on your frame.

There are two version , ISCG03 and ISCG 05 standard, we can propose the both version support.


Note that :

ISCG 05 is the most popular, (theoretically bike from 2005 to the present)

ISCG 03 (or ISCG old) tends to disappear (theoretically bikes between 2003 and 2005).


95% Of bike have generaly ISCG 05 so please prescise if you have ISCG 03 frame.

-2.1- If you don't have ISCG tab's.

If your frame is compatible and if you have ISCG tabs, that's OK for add our bolt on motor kit on your bike!


But if you don't have ISCG, You must add ISCG adaptor for convert your bike into e-bike.


So we have adaptors for almost frames on the marquet, so below, is the différents solutions for add adaptator on your frame, for fixed the electric bolt on motor depending of your Bottom bracket.


If you Don't know what kind of Bottom bracket is on your bike, you can clic on the link below for more infos.

-A- If you have BSA (34.5 mm threaded) bottom bracket :


The adapter for fix the LIFT-MTB electric assist system on BSA threaded bottom bracket frame is the TYPE A.

-B- If you have PF30 Bottom bracket (46mm ID frame)

With this adapter you can add a thread on press fit 46mm frame and screw the conventional BSA cups and use the same adapter as in the first case (A) for fixing the electric kit on bike.

-C- If you have BB30 Bottom bracket (42mm ID frame)

With this adapter you can add a thread on press fit 42mm frame and screw the conventional BSA cups and use the same adapter as in the first case (A) for fixing the electric kit on bike.

-Axle size 24mm : Race face , Shimano hollowtech,  FSA (steel axle)

-Axle size 22mm left , and 24mm right: SRAM gxp. (steel axle)

-Step 3-

Check the standard of your bottom bracket axle ? 

In the kit is included, different types of axle diameter adapters, for to be compatible with the different models on the market: 



- 24 mm: Race face (steel axle version) and Shimano Hollowtech, some FSA.

- 28.99mm: SRAM DUB ( aluminum axle).

- 30 mm: Rotor, E13 , Race face , HXR (aluminum axle).

- Axle diameter 22 mm left side, and 24 mm right side : SRAM GXP.

ELECTRIC FAT BIKE with our electric motor kit
electric fat bike lift mtb


We also made a specific 2 axles length for ELECTRIC FAT BIKE.


-Axle crank In length 170mm

(for electric conversion FAT BIKE with rear wheel spacing  170mm)


-Axle crank In length 190mm

(for electric conversion FAT BIKE with rear wheel spacing  190mm).


Example of taking measurement of the a frame or a rear hub to define the standard used on a fat bike frame, there are two versions 190mm or 170mm.


This measurement is only necessary for fat bikes.


For the transformation of your bike into an electric mountain bike with the LIFT-MTB motor, there is 3 axle length  are available:


- Standard bike axle (XC, All Mountain, Enduro, DH ...)

- Long axle, 170mm for Fat-Bike

- Long axle, 190mm for Fat-Bike
