E-scooter BMW C evolution in the test

I recuperate!

In the test, we determine how the BMW C evolution electric scooter moves in the wild, what it can and cannot do.

I.Some electric vehicles now dare to take to the streets. One or the other Renault Twizzy hisses through the city, quickly moved by the pizza delivery man. BMW i3s, those knobbly electric cars with carbon cells, are not only driven as demonstration vehicles by the local BMW dealer, but also by solvent eco-owners.

Two enemies: mountains and highway

On the country road, too, you will be delighted with the weightless torque development of the BMW C evolution. The e-scooter glides almost noiselessly over slippery roads, and the top speed of 124 km / h is enough for an overtaking maneuver if the vehicle is clearly running out of breath at 110 km / h.

The electric scooter has two enemies: mountains and highways. He hates the mountain because, in addition to the crew, it also has to lift its lush 268 kilograms. This increases the driving resistance and so does the current drawn. On the highway, full throttle orgies in the 120 km / h range drain the battery pretty quickly. Consistent slipstream driving behind parcel service sprinters doesn’t help either. The calculation is simple: to achieve 120 km / h, it needs around 14 kilowatts of engine power. With a battery capacity of 8.5 kilowatt hours, you can drive 36 minutes, which corresponds to 73 kilometers.

So there’s no point in driving the BMW C evolution like a combustion engine. Refueling is not an option, empty it takes a good four hours until the lithium-ion battery is full again. A little neighborhood-friendly cooling fan is still making noise, and sometimes there are also unpleasant smells. So what to do Planning is the order of the day. The nicely designed TFT color instrument shows the percentage of charge left in the battery. When commuting, you quickly get a feel for the remaining range. Accordingly, the charging stops are placed in a nerve-friendly area. My eight kilometers to the office for a week, that works well. Just take a walk? Actually works well when you have yourself under control. You have to consistently save energy.

BMW C evolution with reversing aid

So don’t accelerate brutally, even if it’s terribly fun. Ride as gently and constantly as possible on the mountain and a maximum of 80 km / h on the flat. Then the air resistance of the BMW C evolution is still low. Downhill comes the culmination: This is where energy is generated! Juchuu, I’m recuperating! A great feeling when the battery is one or two percent fuller at the end of the slope and the range increases. Braking is fun too. Because depending on the selected driving program, the motor brakes the load more (dynamics) or less (Road) or not (Sail) and thus generates electricity. In the EcoPro program, the power consumption is limited in the lower speed range, thus protecting the battery.

I prefer the Dynamics program. Here you brake the BMW C evolution so well with the throttle that the brake levers almost never have to be used. Extremely relaxing. The absolutely gently adjustable power delivery is just as cool. Slow walking pace is not a problem. You also quickly begin to appreciate the reversing aid when pulling out of a parking space. At the same time, press "R" on the handlebars and accelerate, and the ship will roll backwards.

At some point it starts to be fun to save electricity. I do not know why either. You just slide around and take it easy. You use the red light to generate a lot of electricity. Even the smallest gradient makes you happy because the current display also conjures up bars on the credit side. And so you are quite proud when the daily kilometer display finally turns into three digits. The BMW C evolution definitely evokes a pioneering spirit plus a touch of playfulness. I understand that now.

There is no economic reason to buy

Because there is no economic reason to buy the BMW C evolution. It sucks 9.22 kilowatt hours per battery charge, which equates to 2.30 euros at an electricity price of 25 cents per KWh. A comparable combustion motorcycle to the Honda NC 700 needs about 3.5 liters for the same distance, which makes 5.25 euros. So you save three euros per 100 kilometers, but the Honda costs 9,000 euros less. The scooter will hardly reach the 300,000 kilometers to amortization.

As a city vehicle, however, it is quite practical. After all, there is a helmet compartment and the side stand locks the brake so that it cannot roll away. On the other hand, the seat height and the wide center tunnel, which hardly offers any space for the feet, are displeasing. The clattering cladding and the louder gear whine with increasing mileage are also disturbing. The hard rear suspension hits uncomfortably on heels.

Still, I’ll miss the Stromer. With one economic reason to buy, BMW built the first really well-functioning two-wheeler with electric drive and street legal, with ABS, slip control (great in the wet) and even drag torque control for safe recuperation. Great praise. And you learn to appreciate something completely new: how valuable energy actually is.
