I tested and compared the 2016 Bosch and Yamaha electric bikes (Haibike XDURO and SDURO models) and was able to take a detailed look at the motors, batteries, display units and chargers off the bikes. What I found is that the combined motor and battery weight for both systems is exactly the same at 14.1 lbs and that with the Bosch CX Gen 3 unit the torque was very similar to Yamaha but offered a wider range of supported pedal speeds (higher range of powered cadence). Each system has four levels of assist but they vary slightly.

Bosch Performance Line CX, Gen 3 for 2016:
– 250 watts to 350 watts power output
– 75 Newton meters of torque (60 Nm on non CX motor)
– 36 volt 11 amp hour Powerpack 400 battery
– 2.2 amp charger weighing 1.7 lbs (0.77 kg)
– 8.8 lb (4 kg) motor, 5.3 lb (2.4 kg) battery, 14.1 lb (6.4 kg) total
– 16T or 18T sprocket
– Assist levels: Eco: 50%, Tour: 120%, Sport: 190%, Turbo: 275%, CX motor: (Sport: 210%, Turbo: 300%)

Yamaha 2016 electric bike system:
– 250 watts to 500 watts power output
– 80 Newton meters of torque
– 36 volt 11 amp hour battery
– 4 amp charger weighing 2 lbs (0.91 kg)
– 7.6 lb (3.45 kg) motor, 6.5 lb (2.95 kg) battery, 14.1 lb (6.4 kg) total
– 38T sprocket
– Assist levels: Eco+: 50%, Eco: 100%, Std: 180%, High: 280%
