    My DR350 needs to go

    Howdy folks. I want my garage space back and I'm selling my titled DR350 elmoto for basically the cost of parts (or perhaps even less).

    It is a great bike. Any early bugs were worked out long...

    I bought a Curtis PB6 early in my build without much research. Within 1000 miles, the unsealed potentiometer got dirty and throttle response became less smooth. I had to open the pot and clean it. ...

    My relay uses DC to switch my full AC charging current as Tony mentioned. That's why my relay's a heater.

    Yep, low current DC-DC should be ok.

    Hi Hugues. If the head bearings are ok, I agree with you- look at the forks. Particularly, does the resonance change if you change the stiffness of the forks (and/or damping).

    Interesting. The Zero setup still weighs 2x over an equivalent Rotax 503 and the Zero still costs more. An ME1003 motor has ~20% more torque though...and the Zero motor would top that. That helps...

    Hi Hugues. It's worth checking those cells. Even my 20 60Ah CALBs don't sag near 2.2V when briefly drawing 350A+. And, my pack is small (by design) compared to most here. Here are some plots from...

    I agree much cell surface area is confined inside the pack and heat's not able to directly radiate outward. This gets even worse as adjacent pack size grows.
