    KT-22a controller surging on PAS use - new install

    Guys, I've installed several KT controllers without issue, including an identical install as this one. This one is presenting me with a challenge I'm wondering if anyone else has run across. Using an LCD-3 display, 500w geared hub. Seems to happen in any PAS level, but not when using the...

    Noisy Ultra M620 gears?

    Just got a new Ultra based bike, and quite honestly, am not happy with what I think are noisy (metal) gears. My question is regarding the plastic gears used in the earlier motors (BBSxx). Would those work in the newer style M620 that comes with metal gears? If so, anyone source them lately...

    1000w + geared rear hub source?

    Guys, can somebody give me a hand please. Trying to source a 135mm gear drive rear hub. I have a 26" bike with an existing 1500w direct drive hub (135mm drop out). It's using a 12 fet 35 amp KT controller and LCD3 display. Though the bike is working great, I would like to try a gear drive rear...

    Opinions on Slime (or similar products)?

    When complaining about the constant need to air the tires on my bikes, I've been told by several "experts" (bike shop employees) not to use anything like Slime. This past March, so frustrated by new tubes requiring frequent need to be aired, I tried some Slime anyway. Need for frequent tire...

    New RadCity with loose spokes?

    20 miles or so into familiarizing myself with a new bike, and I hear something rubbing/clicking in back while coasting. Checking all the usual suspects, I find no good reason, and it won't make the noise without my fat butt on it. I had read about others having some issues with loose spokes...

    Replace RadCity SW LCD with SW 900 LCD

    New RadCity, love the bike itself, but the SW LCD control functions are very limited (understatement). Much prefer and used to those available with the SW 900 LCD. I'm willing to spring for the new LCD, but have a question regarding compatibility with the Rad motor controller. Wondering if...
