Differences between "PRO " and "CLASSIC" KIT.

100% made in France CNC axle spindle

Whatever the range, we use chromoly steel crank spindle axles 100% CNC machined in France, with flat square design an oversize diameter of 22mm, arms with double clamping screws by pinching, this is a standard used for high range BMX cranksets, so it's super strong !


Not to be confused with the small diameter 12.6mm square tapered basic steel crank axles, used for cheap bikes, which are completely outdated.




The use of the LIFT MTB kit requires a crank with a freewheel on sprockets, it is neccessary if you accelerate without pedaling, with this system the arms are not dragging by the motor (see video at the bottom of page).


The kit can not work without this kind of system, that's why a specific crank is inclued with our kit.


There are two versions of the LIFT-MTB Kit: V4 CLASSIC and V4-PRO


The V4 "CLASSIC" kit is the same as V4 "PRO" in terms of engine and power.


Both types of kit PRO and CLASSIC , have both a freewheel system, whether the PRO or CLASSIC version the function will be the same, only the overall weight and précision of the freewheel changes


Here are the details that make the difference between these two versions:

 The 4  Main specs for the "CLASSIC" crankset:


-1- Spindle axle chromoly steel, with axle diameter adapters. (22/24, 24 mm, 29mm , 30 mm)

Available in different lengths to be compatible with all frames (xc / enduro / dh / fat bike).


-2- DICTA chromoly steel free wheel 20 points of engagement per turn , 2 pawls and x1 spring.


-3- 170mm 6061 aluminum cranks, laser graving.



-4- Weight 1025 grams

(value of the "classic" crank alone except kit 249euro).


The 4 main specs for the "PRO" crankset:


-1-CHROMOLY hollow axle , with axle diameter adapters. (22/24, 24 mm, 28.99mm (DUB), 30 mm).


Available in different lengths to be compatible with all frames (xc / enduro / dh / fat bike).


-2- freewheel 6 pawls and 6 spring , 72 points of engagement per revolution, for better responsivity.


-3- Aluminum superlight 170 mm arms, 7075 T6 CNC machined in France


-4-Weight 775 grams

(value of the crankset only "PRO" except kit 449euro). 


-With the PRO you will save 250 grams. You will have a better responsiveness, and it will be more precise during pedaling part's due to high range freewheel.
-The overcost will be 250euros For the
