5-speed Auto e-shift hub

The RG E510 is an eBike automatic shifting system from Bafang’s GVT series. It reads pedal force, cadence, and speed, plus a 6‑axis IMU for terrain awareness, to downshift before climbs and upshift on descents. The motor stays in its efficient zone, and the system returns to starting gear at every stop. Manual override gives you control. Less derailleur hassle, lower maintenance, and over‑the‑air updates. Always smooth, always ready. Experience why automatic shifting makes every ride feel effortless.
