Differences between "HXR " and "CLASSIC" kit.

The use of the LIFT MTB kit requires a crank with a freewheel, 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: V3 CLASSIC and V3-HXR
The V3 "classic" kit is the same as V3 "HXR" in terms of engine and power.
Both types of kit HXR and CLASSIC , have both a freewheel system, whether the HXR or CLASSIC version the function will be the same, only the overall weight and prescision 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- ISIS axle chromoly steel, with axle size choice of shaft diameter. (22/24, 24 mm, 28.99mm, 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.


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


-4- Weight 1025 grams

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