🔋 Premium eBike Battery – The Wedge Series

Lekkie designed the case in-house, later refined for mass production by Reention. Its mission: to create a small but mighty battery that fits in tighter frame spaces without compromising output or safety.
Every pack is hand-built by Bicycle Motor Works — not overseas. That means we control every detail, ensuring genuine premium cells, top-grade BMS components, and unmatched build integrity.
