Wispers are whispering. An "h" no the be heard to differentiate the "bike" of the "wisper". This can resume the work that has made by Wisper to give birth to this new generation of electric bikes for which the 2R Aventure is the exclusive distributor in France. A simple series, easy to understand: the Dutch city bike, comfortable for women as for men called 705, the man sporty version named 905 and the almost ATV if it is not completely hybrid : the 929. Reinforced mechanical elements, an impeccable finish, latest technology of electrical assistance, safety and comfort, and above all a racy, powerful and quiet bike. Be surprised, this is a wisper !

  • A Wisper frame , lightweight, reinforced for heavy use (the electric bikes are rolling nearly two times more than a standard bike). It is hand welded aluminum alloy 6061 T4 and T6 tempered with clean weld seams (that connoisseurs can admire, art can be in the weld seams!).
  • The revolutionary new batteries from Samsung. The evolution of battery technology has been very important in recent years. We have always tried to offer our customers the best and the most reliable technology on the market and today we are proud to offer them what we see as a double revolution:
    • The RCSS system(Remote Control Service System): this system connects the battery to a computer via a USB cable (USB drive is available when the battery is removed from its rack) to review the history of the battery and diagnose problems if any. It also enables to update the software of the battery management to optimize its use. Eventually, the battery trought its USB port can be used as an extra charger for charging a phone or tablet. A whisper at the cyclist's ear to provide the best advice and a revolution at the time big data to guide to the best use.
    • The deep sleep mode . While current batteries may require recharging and regular use, the new Wisper batteries can hibernate. If the battery is charged to 80% or more during a long storage, deep sleep mode optimizes the load for 12 months without having to recharge the battery. This mode is accessible with a button or automatically engages after a non-use of 24 hours and a voltage lower than 39V. Just press a button to "wake up" the battery. Especially useful on bikes that can be used only during the summer period, this mode is a real asset for the the battery lifetime and simplifies users' lives.
    • A new patented torque sensoradapted to a hub derailleur system. The system on these bikes has been developed over the years with experience and an Austrian know-how. It is the fruit of close collaboration of the manufacturer and his partner. It provides unparalleled ride comfort:
      • Silent, bike noise and its elements is almost inaudible to the ear. The bike's wisper becomes surprising.
      • High Performanceand responsive, the combination of a torque sensor on each pedal and a speed sensor enables ultra fast response (36 signals every ten seconds) for the rider to communicate naturally with its mount.
      • Efficient The new system and computer optimization increases the autonomy of almost 40% from a comparable system of single speed sensor.
      • Powerful and racy , the combination of these sensors on the pedal and a motor in the rear wheel eliminates the torque limitation (recommended to 35Nm by major transmission providers in the context of a motor on the derailleur) and offer up to 55Nm in the rear wheel.
      • Robust and reliable , the integration of the motor in the rear wheel optimizes power on the transmission, thus increases its lifetime. In addition, this position provides better engine protection during shock (crossing sidewalks, rocks that can directly hit the derailleur block...)
      • Easy and simple, the Acer 8-speed hub system Shimano can change gears at stop with one finger, forget the difficulties hill starts and enjoy an almost automatic gearshift
      • ATV , or nearly , the motor position in the rear wheel gives a better grip especially on slippery (wet) surfaces, on which the latest technology of Tektro disc brakes makes the difference.
      • The quality of the supplies : 8 speed hub derailleur from Shimano, reinforced double wall Kenda tires, anodized spokes and reinforced at the back, front fork suntour NEX, these bikes were very well equipped and do not need their mane to be brushed to shine!
      • An ergonomic control system: a large LCD screen on the handlebar to specify the level of support, speed, range, the condition of the battery, clock, and an error diagnosis. It is positioned on the handlebar and is controlled by two simple external buttons +/- usable with gloves (to use his bike in all weathers!)
      • A unique luggage rack : certified to 25kg, this luggage rack has been developed especially for bicycles 705 and 905 in order to integrate the battery on the back to ensure the best ergonomics and distribution efforts. Work conducted on this piece simply fits to the frame and create a strong set.
