    Yeah it would have been nice if Brent had replied with the fix. There is so many different things. I was at Acadia National park with my home brew DD hub bike a couple of weeks ago and it started cutting out while using pedal assist but was fine with the throttle. When I got home I had a plan on how to diagnose the problem. A few hundred miles later and the bike won't repeat the problem. You can't fix what isn't broke.

    In your case how about a little more information? Check all of your connections test the voltages here and there. If you aren't comfortable with that take to someone to get it fixed.

    Try disconnecting your brake cut wires and your shift sensor if you have one.

    I watch the voltage draw . And that changes very little. I have 2 battires both stock does the same with both.

    Probably LVC from voltage sag, that battery's over two years old and you're pulling more current than it was designed for. Do you see no cutouts when the pack is fully charged? If these cutouts only happen when the charge is lower than full, then it's sag.

    Yes the battery will drain faster than normal with a higher power controller, the more power you use the faster it will run out. No controller in the world will change that..

    Sondors motor cuts out.

    I have an eirly 2016 fat tire Sondors. When I am riding the motor will cut out and the thumb controlle will not work. I have replaced the PAS sensor and thumb control . I do have a wendys LCD and 2oa controller by Velomobileshop. The battire drans down faster then normal. I have checked the setting . They all seem good. The only thing i can think of is I got a bad controller? Any help would be great. Thanks (i use it daily to and from work) PS is there any benifit to go to a 25A controler with stock battiers?
Working...
