mrelwood Posted February 20, 2017 Share Posted February 20, 2017 Hello! I like to start with a summary: Two EUC's for an Airwheel A3 style device (Segwayish with a seat). 2* IPS 121+/T350+ or 2* IPS Lhotz? I have soon scored 2000km in 8 months with an Airwheel A3, kind of a Segway style two-wheeler with a seat (520Wh, 500+500W). I am physically disabled, so I ride my "Pegasus" every time I leave the house. The Pegasus has truly been a life changing device for me, as I can only walk about 100 meters at a time, and I'm not able to sit in a wheelchair for more than 10 minutes or so. Now I can ride freely everywhere, from nature to grocery store! By default the A3 has a top speed of 15km/h, tiltback starts at 13km/h. This can be upped to 17/15 with (an older version of) the Airwheel app, but it has to be done after every power-on. I recently got the idea of building an upgraded version of the A3 from two EUC's, giving more range, power, a proper suspension, lean while cornering, and a whole lot of more speed. (Detailed plans in the next post.) I have spent dozens of hours reading this forum, all related reviews I could find, and gathering a spreadsheet with specs for a few dozen models. I feel that IPS 121+/T350+ and IPS Lhotz are the best candidates in a reasonable price range. A few things are left uncertain however: 1) 121+/T350+ or Lhotz? The plastic casing is going to be mostly removed. 2) How can I make sure that I purchase a version of the device that is compatible with atleast the IamIPS app, has selectable drive modes, and the top speed of 30km/h? 3) Does the fellow Kevin's app "XIMA Lhotz" work with the latest IPS versions? Does it work with the 121+/T350+ at all? 4) Where should I buy the IPS's from? I live in Finland. I have found only Electricunicycleonline (no Lhotz) and IPSelectricunicycle (free shipping). 5) Anything else come to mind regarding a project like this? Thank you for this great forum! It has already been invaluable for me. Link to comment Share on other sites More sharing options...
