🚴 Koolux BK6S PRO folding electric bike – the electric bike that made the test team believers
When the Koolux BK6S PRO folding electric bike was delivered to the European electric bike manufacturers’ shared test drive point in Kruunuvuorenranta, Helsinki, the test team didn’t know what to expect. But when the first test rider stepped on the gas, the 750-watt motor roared like an electric beast and the bike shot up the dirt road at such a speed that the test papers were forgotten and only one thought remained:
“Wow, what an electric bike, I want that!”
The test drive was no longer a test drive. It was an experience. The terrain turned into a track, the asphalt into a silk road, and the hills into challenges that the Koolux BK6S PRO devoured for breakfast.
🌲 Off-road muscle, city agility
The Koolux BK6S PRO folding electric bike was anything but cautious during the test ride. It moved smoothly along the streets and pedestrian crossings in Helsinki, but when the route took us to the forest trails of Kruunuvuorenranta, the game changed. The 20-inch thick tires bit into sand and roots like a fox into a bag of candy, and the 750 W motor accelerated the rider up steep climbs without breaking a sweat.
The bike covered up to 150 kilometers on a single charge, and it was done in one sitting – thanks to the powerful dual battery. The foldable frame made it easy to pack in the car and take it on a trip to the cottage or to the basement of an apartment building.
