    1000 watt?

    My affliction continues. Is anyone getting 1000watts out of there sonders with the 20amp controller, aftermarket display and 52volt battery. I would love to put a middrive on this bike but I'm going to loan it out to people to ride with and want to stay ahead.

    I went in another direction. I bought the 750watt fatbike rear hub kit from luna. I found out after the fact that the 25 amp controller has a harness for throttle and the display only. If I was to do it again I would order the motor only and source the controller with all the hipo plugs and aftermarket display for sonders.

      Buy the rear 750w motor AND the front 750w motor from Luna. Use a 3rd party 35 amp controller and with a full charge you are looking at more than 4000 watts. Not 1000. 4000.

      58.8 volts x 35 amps x 2 motors = 4116 watts

      Luna Storm battery for the rear. Two 30Q Mini Cubes up front in the handlebar bag along with another controller.

      Ordinary riding is amazing using just PAS since the power is now applied to both wheels. Starts from a stop are effortless. Actually everything is effortless. Use throttles rather than PAS and acceleration is freaking crazy. You have to dial down the wattage to the front wheel to stop from doing burnouts if you hit the throttle too hard. Wears the tire down.

        Nice looking set up. What rear rack is that? It's nice and tall.

      Sorry for the delay in response mtm308. The rack is a Axiom Fatliner. Ordinarily you want loads to have a low center of gravity but compared to an Ibera that puts the rack top just over top of the tire, I don't notice any performance difference and I ride with loaded panniers daily.

      if you research it and notice the unusual way it mounts to the lower dropouts, they sell an 'axle kit' that you can add - originals on the outside, spares on the inside - with some steel spacers to double the connection to the frame. I can provide pics if interested.

        I'd actually love to see some photos. My SE fatbike doesn't have any mounting holes for a rack. I'm currently using some hose clamps as mounting points.

          Well i you have no dropouts pics of what I did won't help you as dropouts are required.

          here is a link to the rack and the axle option. Its not for heavy loads. I saw a post with a guy who was carrying water jugs with his rack and the extensions bent at their contact point with the axle. Not a big surprise.

          the rack: http://a.co/7CwwVeM

          the axle conversion bits: http://a.co/cflGV9K

          I doubled mine up by mounting one set on each side of the rack supports using longer bolts thru the support. Spacers in between them (you could use flat washers but I used 1/2" thick 5/8" spacers as they had a larger OD) along with longer Grade 12 mounting bolts for the rack bosses.
