Can you explain what the power specs 750W and 100Nm torque in simple terms really mean for Bosch Gen 5 motor?

What are advantages with an increase in power for each of these parameters and how does the additional power translate out on the trail?

@Singletrackmind, good question, and one that's worth breaking down properly since "750W" and "100Nm" get thrown around like confetti without much explanation of what they actually do for you.

Torque (100Nm) is rotational force, the grunt that shoves you up a hill or out of a corner. Think of it as how hard the motor can push the cranks. Higher torque means more force available at low speeds, which is where you feel it most: steep technical climbs, restarting on a gradient, powering through soft ground. At your weight of 100kg on a fully laden eMTB, that torque is what stops you grinding to a halt on a 20%+ pinch. The Gen 5 went from 85Nm to 100Nm with the May 2025 firmware update, which is a meaningful jump. In real terms, climbs that used to require perfect line choice and momentum now have a bit more margin for error.

Power (750W) is how fast that force can be delivered, essentially torque multiplied by cadence. Where torque is the shove, watts determine how long the motor can sustain that shove as your speed increases. The old 600W ceiling meant the motor would "cap out" earlier at higher cadences, so you'd feel it taper off mid-climb if you were spinning quickly. The bump to 750W raises that ceiling, meaning the motor stays in the game longer as speed increases. In practice, you notice it most on sustained fire-road climbs or moderate gradients where you're pedalling at a decent cadence rather than grinding.

Have you seen any traffic on threads with big brand motor manufacturers releasing software updates to increase torque/power to keep pace with DJI?

Will be interesting to see if Bosch or Shimano make upgrades to power setting via software updates in time for the Sea Otter Classic.
