About 10 years ago, a sure French firm known as Furion paired a twin-rotor, 654cc Wankel rotary engine with a 40-kilowatt electrical motor to provide an enormous 180 hp and 151 lb-ft (205 Nm) of immediate torque on a bike. It was known as the M1 and was already fairly sick for its time.
Now, rather less than a decade later, the corporate has turned up with its successor, the M2 prototype. It’s based mostly on the Yamaha MT-07 and its much-loved CP2-powered platform.
And this time, it’s an all-wheel-drive mannequin, due to an extra electrical motor on the entrance wheel. You get an axial flux design, with coils, a magnet, and two discs. The top consequence? Near 221 lb-ft (300 Nm) and over 20 electrical hp out there on the entrance wheel.

The rear wheel is powered by the 689cc parallel twin CP2 motor that generates round 73 hp. Each entrance and rear are electronically managed, leading to round 93 horsepower of peak hybrid energy from its all-wheel-drive system.
The bike world hasn’t seen many hybrid fashions. The likes of Kawasaki’s Z7 Hybrid and Ninja 7 Hybrid are a few the uncommon few torchbearers. However Furion’s strategy is totally totally different than what we’ve seen earlier than.
Furion remaining model
On the heart of all of the engineering is the digital management system, which Furion calls the Eversor. It controls the torque available and manages real-time drive energy distribution between the entrance and rear wheels. Its aim is easy: to supply one of the best traction attainable in each driving situation.
In contrast with the standard single-motor setup, the entrance motor can recuperate as much as 5 occasions extra vitality underneath braking – changing as a lot as 27% of the bike’s kinetic vitality into electrical energy. Underneath braking, weight transfers ahead, growing load and traction to the entrance tire, making regen from the hub motor near preferrred.
As an apart, I can see the debates it would trigger for people who trail-brake into corners and those that do not.

As for the battery, it appears prefer it’s positioned on the rear finish of the bike. However one could marvel: “If the engine already makes electrical energy through the stator, why trouble including a battery in any respect?”
On paper, utilizing the stator by the regulator/rectifier to energy auxiliary electronics appears less complicated. Bikes have completed that ceaselessly. The likes of headlights, gauges, heated grips, and USB retailers are all powered instantly or not directly from the engine’s alternator with out a battery when you’re rolling.

So why does Furion trouble with an extra lithium-ion pack? The reply comes right down to what the battery allows.
First, the battery shops electrical vitality so the system can ship bursts of help torque even when the engine isn’t spinning quick sufficient to provide that present instantly. With no battery, the hybrid help can be weak at low RPM, really feel jerky, and certain trigger electrical pressure or instability.
The battery may also assist with capturing vitality underneath braking, storing it, and re-deploying it for help later. It additionally smooths voltage, ensures a continuing provide, and protects microprocessors from glitches.
Take hybrid vehicles, as an illustration. More often than not, the engine drives a generator whereas the battery absorbs and delivers energy. You by no means see a hybrid with out a high-voltage battery pack as a result of the help capabilities cannot operate with out it. A motorbike hybrid is identical idea – simply scaled down, a lot lighter, and all of the tougher in packaging.
And it’s not just like the M2 is only a lab prototype. The bike was really examined on the Pole Mécanique d’Alès Cévennes. 4-time Supermoto world champion Adrien Chareyre rode the M2 and had optimistic suggestions on the M2’s rideability and grip.
“We have now designed Eversor to deliver again actual using sensations whereas fixing the vary equation. Our know-how is now accomplished, track-tested, and guarded by worldwide patents. It’s supposed to grow to be a normal for the worldwide business by licensing agreements,” mentioned the corporate.
Furion intends to launch its personal sequence manufacturing bike to place the Eversor on an precise, operating mannequin – the F1. Designed by Takumi Yamamoto, it’ll be a premium bike that might be manufactured in a restricted amount of about 100 models yearly.
We don’t know a lot concerning the F1 but, however it’s mentioned to have round 186 miles (300 km) of vary. So far as we are able to inform, this can be a self-charging hybrid, with the battery replenished by regen quite than a wall outlet – so a cease at your favourite fuel station ought to get you again on the highway once more.
Based on Furion, by 2029 the Eversor tech may also be made accessible to different producers by licensing fashions, with the tip aim of standardizing the know-how and turning your favourite bike right into a 2WD hybrid.

Combining a standard combustion engine with a hybrid front-wheel electrical drive all however eliminates EV vary anxiousness. It additionally means decreasing the potential drawbacks of a really heavy, pure-electric bike. On the similar time, it retains the standard using expertise of shifting by gears and an inner combustion engine soundtrack.
Extra importantly, including front-wheel-drive opens up new potentialities for traction, stability, and acceleration, particularly whereas using on moist or slick surfaces – to not point out potential race use!
