1/ Choose crank version PRO or CLASSIC:

The V4 "CLASSIC" kit is identical to the V4 "PRO" in terms of power and engine specification.


Only the crankset changes between the two versions, the PRO version saves 250 grams, and offers a better reactivity, and more precise relaunching thanks to a more precise freewheel.


 Only experienced riders will notice the difference with the PRO.


The extra cost of the PRO model will be 250 euro compared to the CLASSIC version.

3/ How to chose the Axle size ?


The LIFT-MTB "V4" system allows you to keep your bottom bracket and change only the cranks without disassembling or changing the bottom bracket, which makes changing configurations quick and easy.




If you want to quickly change your bike from one configuration to another, you will only need to put on or remove the axle diameter adapter set that corresponds to your current bottom bracket axle.

In the kit is included, axle diameter adapters, to change the kit axle on all standards: 


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

- Axle diameter 28.99mm: SRAM DUB (version with aluminum axle).

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

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


The axles are compatible with the widths of cases:

68/73, BB92 (classic bikes) but also 83 mm and BB107 (Downhill bikes).


We have 2 axle sizes for Fat Bike in 170mm and 190mm.

Chain guide option:


The LIFT-MTB aluminium chain guide is adjustable. It allows to limit the risks of derailment. Compatible with the frame-mounted plate, for the internal mounting versions the chain guide can be integrated, this option can be added at the time of purchase or at a later date.




Price 59 € ( 49 € outside Europe) 


Optional Bash Guard :


When mounted under the frame, it is extremely rare that the electric crankset motor kit touches. In general, if it were to touch, it would be at the level of the chainrings which are at the same height as on a classic mountain bike.


(For more information on ground clearance, click here to access an article on the subject).


That's why we have innovated a system of chainring protectors that can be adapted to the motor plates of the V3 to V4 version.

Pedelec for LIFT MTB
Pedelec for LIFT MTB


This sensor makes it possible to have an operation identical to that of a traditional electric bicycle like a Bosch MTB motor for example:


When the crankset turns, the sensor detects it and the crankset motor sends power to assist the rider, without the rider pulling the trigger.


The power of the assistance can be adjusted by turning the knob on the stem.


The trigger on the handlebars will remain active even if you are not pedalling, allowing you to accelerate without pedalling if necessary.

This option can be added at a later stage or directly when purchasing the kit.
