Lekkie Nucleus ISIS 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 ISIS crank set is designed specifically to fit the latest ISIS drive production motors. With an optimal offset, the q-factor is set to meet industry standards and work with a variety of ISIS motor systems.

Crank length of 155mm.
