    Safety/protection requirements for 'naked' blue battery

    Hey All- Looking at lots of different posts here on cases and bags for batteries, one thing I haven't been able to find is what sort of general requirements are considered normal for a blue/naked battery. I was thinking about making a frame from aluminum angle, and possible sides with black...

    GMAC vs MAC and Infineon vs Phaserunner

    Hello all- I'm planning a new build on an edgerunner and was hoping for any feedback here. I've pretty much settled on a MAC or GMAC motor and was looking at the Grin kit vs the EM3V kit vs a bit of each. My priorities are relatively lightweight, would like to have ~1500w acceleration...

    Original Rock Shox SID with Q100H?

    2WD Radwagon upgrade questions

    Hey All- New here and recently got into ebikes with a Radwagon, and have been pretty happy with it and enjoying riding/commuting by bike a lot. The main thing I would like to change is to get a longer range, but I also would really like more acceleration and climbing speed. After reading up a...
