      Thank you so much for making this real. No we see there is a real market for special mounting brackets also. We will prepare updates for every second week to show you the progress. We are sure we can ship all sets very early so you will have your add-e right from the beginning of the new year. What a wonderful start, THANK YOU.

      @ Lee; no pedaling full 250 W about 35 min

      @ Joachim; The battery can be also mounted on the cross brace. Maby there will be an option to put the battery in a bag.

      Hi, may I know how far can it go non pedaling with full throttle using 250w battery?

      The position of the battery will block official Bromton bags when folded unless it can be easily deattached. Did you think about bags?

      That nice. Please kindly upload the pic of Brompton folded state with add-e installed.

      @ Jaan, yes you can fold it as you are used to it.

      @ We made already some improvements, but more after the Holidays.

      Congrats on reaching the funding goal prematurely! Have you already started working on the project? :)

    15. Jaan Hua on December 21, 2015

      Can we still fold the Bromptom as per normal with the add-e install?

      Hi. May I know what is the waterproof rating? Sometime caught in the rain and no shelter around.

    18. add-e powered by GP Motion Creator on December 10, 2015

      @Lim Kay Kheng - Currently we do not have any problems with that.

      @ Rudy Thank you so mauch :)

    19. LIM KAY KHENG on December 9, 2015

      Hi Like to know would you have issues shipping with the battery and the motors to Singapore?

    20. Rudy Sijnke on December 8, 2015

      I just pledged €40.00 for the Add-e throttle! I'm sure you guys will hit the goal in time, good luck!!!

    21. add-e powered by GP Motion Creator on December 8, 2015

      Thanks to all for this encouraging words.
      @ Splash: There are other products out there but as we tested a lot I can say add-e is unique. As most other friction drive systems do have problems in the wet add-e works perfekt also in bad weather conditions :)
      As I presented the drive long time ago (first 2009/10). We have no problems with new patents and the old ones we checked. (2012 first international award - INTERNATIONAL STUDENT COMPETITION IN MAKING OF E-BIKE / PEDELEC)

      Great project. This product does seem to be similar to others out there. Do you have any patents or are you aware of any other companies that have patents on this kind of device that might affect your ability to deliver.

      You've just revolutionised commuting ! This would make my commute so much easier. Fold away bike that I could get on the bus or train then that added extra power to keep up with traffic and get me to work or home faster. You guys have nailed this and I really hope you get the full funding to make this a reality
