    Mostly working CA3-DP

    ** SOLD ** Speedometer stopped working. This is the second time this has happened with my setup and I don't know why, but it's easier to just buy a new one than try to figure it out. Everything else works fine as far as I know. Plug is obviously modified and will need to be remade. No...

    Tangent Ascent 40:1 3210 kit $1200

    I bought this from another user on Endless Sphere in 2016, installed it on one of my bicycles, and rode it for less than 100 miles. The bike has sat in my shop ever since then. This was my first try at mid drives, and it turns out I just don't like them. I prefer the smooth, silent, instant...

    Building a solid rim for my QS205

    I've read the threads about solid rims / mag wheels / people breaking spokes. I'm well aware that a traditional spoked wheel has many advantages and a way better strength to weight ratio than a mag wheel ever could. I'm on board with Chalo's explanations about spoke tension and stretch and...

    QS 205 / Sabvoton hall signal issues -- wires or halls?

    Over the winter here in the Pacific Northwest, I rode my electric bike a lot, and slowly started having problems with the power cutting in and out on my motor. I finally took everything apart and tested the signals from the hall sensors. The results were an input voltage of about 4.98 and an...

    Help identify this battery

    A guy is trying to trade me this kind of sketchy looking battery for some fabrication work. Appears to be 14S and all individual pairs on the BMS leads read out to 3.31 +/- .03 so that seems pretty good. I'm going to try charging and discharging it, but I'm curious if anyone recognizes it as a...

    Half-upright/half-recumbent electric cargo tandem

    Hi everyone! Several years ago someone gave me an old ATP Double Vision tandem recumbent frame. I had to do some frame repairs, and then built it up and rode it that way for a while. Later, I decided I would rather have a half-upright/half-recumbent style tandem like a Bilenky Viewpoint or a...
