    Hello, I ordered you the SpeedBox2 for Yamaha PW on Saturday, I received it from Monday !! For fast delivery it's fast !! I climbed it and I went for a walk on flat paths. Super good product !! Thank you.

  3. Damien (Customer confirmed) -

    I am completely satisfied with the KIT SPEEDBOX 2 PW, essential in flat phases and descents in order to relaunch to attack the climbs. Super easy to install and to protect it from shocks, I put it in a piece of inner tube.

    Delivery Time: I ordered it on Saturday and received the following Monday. We can not do better. Thank you.

    Only one small problem: It regulates to 46KM / H instead of 50KM / H announced.

    Received yesterday the kit quick assembly.
    40 on the dish. With a tray of 44 for me that's enough but otherwise you can mount 46 see 48. After, better, a battery of 500

    I have a bike GIANT 2017 electric assistance.
    Central engine YAMAHA EVOLUTION LINE 80Nm.
    (sport syncdrive)
    the control center is the "ridecontrol" and the screen is a display charge.
    Which de-clamping kit to integrate and which does not modify the indications on the screen should I order?
    the clip-on kit on the wheel modifying the speed and distance indications
    Thank you in advance.
    Best regards.

      To our knowledge, there is no module displaying the actual data for this model of bike. This is why we recommend the badassbox.
      The support

    Purchased in 2017 for a 400 Lapierre FS2016 with Yamaha engine. I find it essential not to feel the cut of 25km / h. We do not ride in real at 50km / h at the limit of unlocking but rather around 35km / h, which is perfect for a mountain bike.
    The display at real speed is essential but I had the daily mileage fairly quickly which reverts to zero when I reach the 20 km traveled.
    It is not a drama in use and I am not sure that it comes from the Speed ​​Box 2.
    Autonomy necessarily suffers because on a 400W / h battery, I do around 45Km in summer and rather 35Km in winter in "playful" mode !!!
    In short, if it broke down, I bought one immediately because I think it essential on bikes over 20 kg!
