VELLO Bike+ Titanium ultra-lightweight e-bike weighs 9.9 kg with theoretically infinite range

[Redaktion]

The VELLO Bike+ Titanium is an ultra-lightweight e-bike, weighing just 9.9 kg (~21.8 lbs). The pedelec's standard model has a top speed of 25 kph (~16 mph), which increases to 40 kph (~25 mph) with a Schlumpf motor. Through self-charging technology, the bicycle theoretically has infinite range; on a single charge, the battery would last for 50 km (~31 miles) without on-the-go charging.

Dude you are full of it.
The bike only has regenerative braking, which at best adds 10-20% to range.

If it was self charging, from thin air, I would be reading about it 5 years ago on CNN.

Theoretically infinite range? Is it because it can be charged by a person pedaling it? By that logic every pushbike has an infinite range! Why do people bother with nonsense like this?

Aside from having a really bad grasp on physiçs, the author pretty clearly has no idea what Schlumpf drive is. Interesting bike, inept article.

It's apparently extremely light and efficient, but not a perpetual motion machine, which would be contrary to the laws of thermodynamics - something you should have learned in high school physics! It's also compact when disassembled but even with a 250-watt battery it's still, unfortunately, not permitted to accompany you on your flight. Finally, it's basically an electric powered road bike and not very practical carrying any kind of load - groceries, gym clothes,  etc. Nevertheless, it would be a fast and fun commuter if not carrying much beyond a light backpack. And the price is really not that much when compared to a typical road bike without electric pedal assist.
