Presented by Online Bike Experts. The NICOLAI R20 MGU – AON Edition represents a revolutionary breakthrough in gravity e-mountain bikes, bridging the gap between elite Downhill World Cup engineering and full self-shuttling capability. Born from an exclusive collaboration between NICOLAI, GAMUX, Pinion, Gates, and AON Racing, this ultra-limited machine pairs the proven GAMUX Sego DH platform with Pinion’s revolutionary Motor.Gearbox.Unit (MGU) and a whisper-quiet Gates Carbon Drive belt system.
Every elite downhill e-bike in our facility undergoes a rigorous 100-point structural integrity inspection, high-pivot linkage calibration, and full Pinion electronic gearbox diagnostic scan by certified technicians. Featuring a hand-TIG-welded 7075 aluminum frame (~29.5 kg total weight), high-pivot rear suspension with 200 mm travel, and an integrated 12-speed electronic gearbox providing up to 160 Nm of torque, the R20 MGU eliminates chain noise, derailleur damage, and unsprung rear wheel mass for uninterrupted downhill speed.
