Specialized 3.1
The highly anticipated successor to the 2.2, introduced with the Gen 4 Levo. Technically, it represents a radical departure: Specialized is ditching the belt drive in favor of a metal gear system. While this slightly increases the weight, it also boosts performance: Since the software update in early 2026, the drive unit delivers a massive 105 Nm of torque and a peak power output of up to 810 watts. The 50-volt system and a decoupled housing for vibration reduction highlight its modern design approach. This is the benchmark for riders seeking maximum power combined with seamless Specialized integration.

Power Characteristics
Shows how much power the motor delivers for a given rider input. The value shown is pure motor power, adjusted for input and drivetrain losses.
Input vs. Output: Specialized 3.1
Looking for plenty of assistance? You got it. The Specialized 3.1 motor delivers strong thrust even with less than 100 watts of rider input, reaching its peak power at around 130 watts. This high assistance ratio is sure to appeal to aggressive riders just as much as those who prefer a more relaxed pace.
Cadence Behavior
Shows the optimal RPM range.
RPM: Specialized 3.1
At low cadences below 60 rpm, the Specialized 3.1 really shows off its high torque, making it one of the most powerful drives on the market. It then ramps up even further, ultimately hitting over 700 watts of output power at around 100 rpm—impressive! However, beyond roughly 125 rpm, the power output drops off significantly.
Thermal Performance
Shows power output performance over 15/20 minutes under constant full load.
20 min
The Specialized 3.1 drive only begins to lose power just before the 20-minute mark, but when it does, the drop is quite noticeable: within a short period, performance decreases by about 20%. At this point, the motor housing reaches a temperature of around 90°C. Afterward, the power output stabilizes at this new level.
