A bike’s clutch might be thought of an unsung hero. It’s a lot greater than a way to have interaction and disengage the transmission, because it performs extra vital roles, significantly in relation to grace and finesse.
It’s additionally a useful gizmo when doing hooligan strikes like wheelies and burnouts…
With the electric age properly and really upon us, it will seem that the clutch’s job is being phased out. A variety of the brand new electrical bikes have a one-to-one drivetrain, with the electrical motor linked on to the rear wheel both through chain or belt, and there’s no want for a transmission, and therefore, a clutch. As a consequence, nevertheless, motorcyclists who need the utmost finesse—which might solely be supplied by the precision slippage of a clutch—are left wanting.
And whereas electrification is a side of life we will’t deny, it’s good to see that some producers have our backs. Zero, for instance, acknowledges the extra finesse and management a clutch offers, because it not too long ago filed a patent on a “simulated clutch” system for its electrical bikes.
The Zero FXE is an electrical motorbike I’m significantly enthusiastic about
Different in precept from tech like Honda’s E-Clutch, Zero’s innovation exists solely to offer one other layer of management separate from the bike’s throttle and brakes. In reality, in Zero’s patent, it doesn’t even make use of the phrase “clutch,” as a substitute calling it a “Vehicle Control System.”
Operationally talking, Zero’s Vehicle Control System sees the addition of a significant part to the bike’s left handlebar: a lever that appears similar to a clutch lever discovered on an ICE bike. The solely distinction right here is that pulling the lever doesn’t launch a bunch of plates throughout the motor permitting it to rev up with out load, however as a substitute, connects to the motor’s digital controller thereby regulating torque output.
Zero’s Vehicle Control System appears to be like similar to a daily clutch
The patent explains: “By reducing the torque output of the engine, the control lever on the left-hand side mimics the operation and feel, for example slippage, of a clutch of a multi-speed transmission present in motorcycles and other vehicles that are powered by internal combustion engines.”

Of course, on paper, that is all thrilling stuff. But we’ll have to attend and see if Zero’s simulated clutch characteristic truly looks like a clutch. It’d be cool should you may hear the electrical motor zipping up as you pull within the lever, akin to that of an ICE bike or a few of the new EV trials motorcycles. Nonetheless, it’ll absolutely make enjoyable stuff like wheelies and burnouts a lot simpler, extra controllable, and to not point out, a lot safer.
It’s good to see producers like Zero investing time and sources to develop expertise that focuses on the subtler nuances of motorcycling. And tech like Zero’s simulated clutch goals to convey again a few of that really feel that’s been misplaced in translation.

And whereas merely including a clutch-like gadget to an electrical motorbike—which on paper, doesn’t actually need it—certainly not replaces the allure and distinctive character of an inner combustion engine, it’s good to know that producers are nonetheless pondering of us fanatics when growing new tech.
I not too long ago joined a moto gymkhana competitors (keep tuned for my full story on that), and have been casually into the game for fairly a couple of years now. The clutch performs a significant function right here, as maneuvering tight impediment programs and successfully placing energy to the bottom contain a better degree of mastery in relation to balancing the clutch, throttle enter, and rear brake actuation.
Quite frankly, I can’t think about competing on an automated motorbike, not to mention an electrical bike. But perhaps this may assist?
