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).

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

1- Check your bike's Frame designs with mid drive motors...

electric kit bike's frame design

Many frames designs could be compatible 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.


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 system LIFT-MTB.


You can also read the page about the e-bike ground clearence.

In this case, the motor will be mounted Inside.

With the V3 you must choose two version :

change your bike into e-bike
move your bike into electric bike

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


You must 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 system is 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).


You must prescice wich type of iscg you need than your frame.

Test procedure ISCG03 or ISCG05
If you have any doubt about the iscg standard of your frame, print the word document in A4 format, cut out and superimpose the papers on your frame.

If you don't have ISCG tabs :

If your frame is compatible and if you  have ISCG tabs that's OK  !


But if you don't have ISCG, You must add ISCG addaptator, we have adaptators for almost frames on the marquet, so below, is the differents solutions for add adaptator on your frame, depending of your Bottom bracket.


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

-A- For BSA bottom braket :

Below is the adapter for fix the LIFT-MTB system on BSA bottom bracket frame.

-B- For PF30 Bottom bracket (46mm ID frame)

With this adapter you can screw the conventional BSA cups and use the adapter as in the first case (A).

-C- For BB30 Bottom bracket (42mm ID frame)

With this adapter you can screw the conventional BSA cups and use the adapter as in the first case (A).

-D-For BB92 Bottom bracket (41mm ID frame)

 This adapter is a complete bottom bracket including right and left cups, bearings (different size), hardware.


It replaces your original bottom bracket but the cups incorporates mounting studs to fix the lift mtb motor kit to the frame. The two parts right and left cups, are fixed by screws for have an optimal rigidity.


The LIFT MTB bottom bracket will be compatible with your original crankset. You can move your bike into conventional bike or e-bike, as quickly as ISCG fixation .


You can choose 3 diametre:

- Axle size 30mm : Rotor, E13 , Race face, HXR (aluminium axle).

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

-Axle size 22mm left , and 24mm right: SRAM gxp.

-3- Think also to the Axle size :

With the LIFT-MTB system you will keep your bottom bracket and replace the crank only .


If you want to quickly change your bike from one configuration to another, you must select the axle of LIFT crank with the same size than your current crank.

There are 4 versions to choose, when you ordering the kit:

30mm Axle diameter: Rotor, E13, Race face (version with aluminum axle).

28.99mm Axle diameter: DUB SRAM (version with aluminum axle).
24mm Axle diameter: Race face (steel shaft version) and Shimano Hollowtech.
22mm Axle diameter left side / 24mm right side: SRAM gxp

Exemple of Fat Bike compatible with our electric motor kit system.

ELECTRIC FAT BIKE with our electric motor kit

We also made a specific 24mm diameter axles for ELECTRIC FAT BIKE.


-Axle crank In length 179mm (for ELECTRIC FAT BIKE with rear wheel spacing  170mm)


-Axle crank In length 199mm (for ELECTRIC 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.
