⚡ Bicycle Motor Works — Curated Performance Line featuring EVE 50PL Cells
Introducing the next evolution of American-made eBike power: the Curated Performance Line.
Curated in Bethlehem. Built for the world.
Each battery pack in this series is powered by the EVE 50PL 21700 high-current cells — an industry-leading innovation delivering 5 Ah per cell and a claimed 125 A continuous discharge rate. Built for riders who push performance boundaries, this line redefines what’s possible in compact, high-output energy systems.
Every configuration is precision-built in small curated runs using Grade-A genuine cells, pure copper busbars, and advanced high-discharge BMS protection. The result: intelligent power that performs under pressure.
