Freak show? Definitely not. The MonoTracer is an interesting approach with high efficiency and just as great entertainment value.

Driving technique – every beginning is difficult? In this case, too, the truth probably has at least two sides. The first: It is not that easy and requires a lot of routine to move a MonoTracer safely. That should put some potential customers off.

The second: precisely because it is not that easy, many see it as a sporting challenge.

Later, when they have made it after thorough briefing, the pride goes with them. Either way, the first few meters are the hardest, for several reasons. The most serious: You move a single-track vehicle without the possibility of putting your feet on the ground if necessary.

Instead, it is important to retract and extend the support wheels at the appropriate time. When starting off, this means gently letting the foot clutch come in (in the MonoTracer with combustion engine) and picking up speed without jolting. In the E-Tracer this is of course much easier. Then it is necessary to watch the moment when the vehicle is in balance in order to retract the wheels using the toggle switch on the left end of the handlebar. This moment costs the beginner to overcome, especially since the MonoTracer, if not well balanced, tilts slightly to the left or right.

Riedener therefore installs a massive crash bar with wheels for beginners, which catches the tracer at an incline of 30 degrees.

Once the start is made, the MonoTracer spoils you with extraordinary driving dynamics. The combination of car seat position and comfort as well as motorcycle lean is an exciting mixture.

Self-supporting composite monocoque passenger cell, reinforced with roll-over protection bars, steering head and support axles made of steel, support wheels that can be extended at the push of a button, upside-down fork (50 mm diameter), single-sided swing arm made of aluminum, a spring strut, double disc brake at the front (320 mm), disc brake at the rear (320 mm), traction control, fully integral braking system with ABS. Is this the new stuff ecomobile dreams are made of?
Driving report: MonoTracer MTE-150
Single-track vehicle with electric drive
Anyone who gets into the MonoTracer MTE-150 should be prepared. Throwing his collected electro ideas overboard. And best of all, everyone else too. The racing capsules hum directly into a new, electrified world?
There is one thing that makes the otherwise calm Roger Riedener really angry. He then speaks faster and louder, gesticulates wildly, almost forgets to steer. "I’m really sick of being part of the freak show! I feel like I was at the fair back then. There was always a woman with three breasts who all gawked at."
W.he Riedener, the 57-year-old boss of "MonoTracer of Switzerland" and accompanies his rolling box in public traffic, understands what he means. But he also understands the onlookers. What do you want to do when such a moving pilot’s cockpit rolls up with a low whirring sound. When – sssssss – the support wheels extend at lightning speed and the side access hatch opens silently? Then at best you expect E.T., at worst a bunch of drooling slime. What you don’t expect is a small, friendly gentleman in sneakers, shorts and a baseball cap.

But this very gentleman has an assignment. The rest of the world may see in its MonoTracers and their followers a few over-the-top recreational mobilists with the necessary change and a tendency to be eccentric, for Riedener it is a vehicle right in the heart of modern future mobility. "The others can build whatever they want there", he preaches with verve from his pulpit crouching just above the ground. "We’ll always get twice as far at the same pace. At least!"
Range, performance, dynamics – these are the terms around which Riedener’s MonoTracer world revolves. Here someone believes in a concept. Definitely, even though it isn’t actually his own, but that of Ecomobil founder Arnold Wagner. He built the first prototype (back then with a BMW K-100 engine) at the end of the 80s, put it on the road and heaved it over all the approval hurdles. Driven by the vision of getting as far as possible as quickly as possible with as little energy as possible and not suspecting that precisely this topic – only around 25 years later, in view of the still unsatisfactory battery storage capacities – would be the central point in every electrification debate.
But where does Riedener get the unlimited trust in the possibilities of his vehicle? First of all, from the key technical data. The cw x A value of 0.19 (0.19 x 0.99 m²) of the MonoTracer tops a motorcycle that is outstanding in this respect like the Suzuki Hayabusa (cw x A equal to 0.30) by lengths and is together with the low one Rolling resistance of a single-track vehicle is one pound that can be used to expand. This is shown not least by the profit of the "Automotive X-Prize", a three-month US competition in which the most energy-efficient vehicles are determined under real everyday conditions and cycles (stop-and-go traffic, overland, highway and much more). The unit of measurement there: MPGe (Miles per gallon gasoline equivalent), i.e. range in miles per gallon. With 205.3 MPGe (corresponds to 1.14 liters per 100 kilometers), the MonoTracer was far ahead of all other class winners (four-seater 102.5 MPGe, side-by-side two-seater 187.5 MPGe). Riedener took $ 2.5 million in prize money to Switzerland. And the certainty that you are on the right track.
Given the key data of the MTE-150, even combustion engine junkies have to agree. The air-cooled four-pole induction motor developed by the US specialist AC Propulsion delivers 204 hp, plus an impressive 220 Newton meters of torque from zero to 5000 rpm. According to Riedener, the 530 kilogram MonoTracer accelerates to 100 km / h in 4.5 seconds, to 200 km / h in ten seconds and regulates at 240 km / h. Even more impressive, however, are the brilliant pulling power. From 60 to 100 km / h in less than two seconds, from 100 to 140 in under 2.5 seconds (manufacturer information): That tops every big bike ever measured at MOTORRAD (which, however, unlike the MonoTracer, always has the option of gear selection) Lengths. Also record-breaking: at a constant 120 km / h, the speeding egg should only consume seven kilowatt hours. With a usable battery capacity of 21 kWh, this makes a theoretical range of 360 kilometers before it has to be recharged for around six hours at a household socket (16 amps).
In view of the dynamism offered, it is not surprising that Riedener was drawn to the race track in Brno instead of the nearest supermarket parking lot to present his MonoTracer and train customers. Where else than in the long, flowing curves can the enormous freedom of inclination (up to 52 degrees) be enjoyed better, and the almost silent thrust of the electric variants more impressively demonstrated. Riedener’s youngest and most powerful prototype is particularly impressive in this regard. It delivers 200 kW (272 PS). In theory, that’s enough for a top speed of around 370 km / h (but only for six minutes in view of the battery capacity) and is also a house number on a Grand Prix circuit, especially since this completely unspectacular way of developing power does not fit into the usual experience patterns.
Silently, but from the first moment with tremendous force, the engine pushes on, only the howling of the gears and the force with which you are pressed into the bucket seats signal the brute propulsion. But you only feel the force with which you really move forward at the next braking point. Where previously – namely on the first test laps with the internal combustion engine variant MTI with BMW K 1200 LT engine – the usual increase in speed, but above all the gear changes signaled the current speed, it is only the crazy thing with the electric tracer The speed at which the curve approaches. Then it only helps to step firmly with the right foot into the composite braking system (the motor brakes strongly with – and recuperates) and to catch the load, which is stable thanks to the rear-heavy weight distribution, in good time before it goes through the corners with the cleanest possible line and without corrections.
But that’s the last step, the high school of MonoTracer piloting. Before that, even experienced two-wheelers need an intensive course, which is primarily due to the design-related peculiarities of the concept. Just get in and drive off, even if the MonoTracer is registered as a motorcycle and therefore only a motorcycle license is required. But even if it were, another hurdle would cause some candidates to fail. Roger Riedener is asking for a good 94,000 euros for his electric MonoTracer (delivery from spring 2012, a version with a BMW K-1600 six-cylinder is also in the works). But everything is on board with ABS, traction control, air conditioning, heating and trunk (160 liters). And somehow the future always goes with it.
