Vrum Cattiva E-bike
Cattiva is a new e-bike from Vrum Bike. An assisted hybrid bike that ensures extra speed and efficiency. The idea behind the Cattiva is that you will only get some electric power when you really need it, say for a little sprint or a hill that gets in the way, other than that, itīs just a normal bike, although much lighter than a regular one. When youīre going downhill or braking just turn your pedals the other way and the batteries will charge with the inertial movement, making sure you wonīt lose electrical juice, in fact you can get around 60kms of range, riding around town, which is enough for most urban commutes. The Cattiva e-bike never gets power from the grid, itīs powered by the Bike+ hub, from ZeHus, a very smart device, in fact researchers found out that this system increases metabolic efficiency by 30% and reduces oxygen consumption by 20%. Italian designed, the Cattiva looks quite unique and interesting to look at. Thereīs even an app to pair it with your phone keeping you updated on its status and info, like speed, distance traveled, slope inclination, battery level, etc Itīs a must have to go around town.
