Lekkie Nucleus CYC Photon Ebike Crank
11 Years of Design. One Defining Crank.
To celebrate 11 years of precision engineering, Lekkie introduces its most refined creation yet — the Nucleus Crank.
Born from the fusion of computer intelligence, human artistry, and precision CNC machining, the Nucleus crank is the result of over a decade of industrial design experience and a will to make the very best ebike parts possible.
Using advanced topology optimization, (optimizes forms for maximum strength) every curve and surface has been shaped for maximum strength and minimum weight.
The result is a crank that is very strong and uses minimum width, optimizing the Q factor or width of your pedals.
Backed by intensive computer analysis, cyclic machine testing and real-world testing, the Nucleus Crank delivers reliability, efficiency and lifts the overall aesthetics and quality of your bike.
The Nucleus CYC Photon crank set is designed specifically to fit the CYC Photon motors. To optimise the q-factor we designed them as a 2-peice crank with CYC Photon specific straight spline axle pressed into the right crank, giving you a narrower, central q-factor on 68 and 73mm builds. Captive crank bolt allows for easy installation and maintenance.
Crank length of 160mm.

Frequently Asked Questions
Q. Will these fit my motor system?
A. Check if your motor is listed in the product specification, or search using the by system menu.
If you can not find your motor system contact Lekkie so we can help.
Q. Why should I choose a long or a short crank length?
A. In general if you are a smaller person you would have shorter crank lengths. For E-bikes shorter cranks can also increase ground clearance and enable higher pedal cadences.
You generally do not need the increased leverage a long crank provides with e-bikes.
