Upgraded to a 48-volt system, the SyncDrive Pro 3 motor delivers powerful, consistent torque at 90Nm and can peak at 800 watts. This ensures smooth assistance even at higher pedaling speeds, reducing heat and energy loss while extending battery life.
How is the bike protected against trail damage?
The Reign Advanced E+ features a titanium skid plate that protects the motor from impacts and corrosion, a dual-density battery cover that shields the down tube, and an active MRP bash-guard with elastomer damping that prevents chain and chainring damage on rough terrain.
