Re: Trying to ID an ebike motor and its controller

Although there may be a hint of of a known model or perhaps a speed rating in these long line of characters, more often they have no meaning (at least to those of us in the West). Especially clones, of which your motor surely is (or perhaps a clone of a clone). It is a "geared" motor. Not ...

Re: Geared Hub Motor Quality

MXUS - what I choose. Nowhere near the numbers for Bafang, and, specifically for their small geared units, very, VERY few breakage reports. Six years, approx 15,000 miles, zero issues. I started w/ a MXUS geared over 10 years ago I got from the long gone Amped Motors and although I don't think it l...

Re: Total Newbie Project- Sea Kayak Propulsion

Those drawings of the kayak are pretty much useless. Do you have a Hobie Revolution 16 or a AI or TI model? If your Kayak doesn't have a Mirage Drive, then it doesn't have a drive-well to drop a motor into. And with the pointed bow and stern, those mounting points are out too. That only leaves a sid...

Re: Rad Power hub motor bearing replacement

I've looked at other Bafang hub motors and some appear to use a considerably smaller connector. I wonder if they all have the same connector problem or if some are actually made with a connector that clears the nuts and bearing? The sm. connector is called a 9-Pin connector and comes on most every ...

When you get the cover free of the cable, just drill two sm. holes in the cover that line up w/ the outer brg. race and knock it out w/ a sm. punch. The holes can be plugged w/ JB Weld. The brg. should have some numbers on the race that can be matched at a brg., belt and chain supply store. Carefull...

As far as leaving the bike out in frt. of stores while shopping, it's probably better in L. Amer. than in the States.

Re: Front Hub Motor with Shimano Mid Drive Advice

Running a frt. hub motor with a mid-drive is not a terrible idea, the OP just needs to lower his expectations. A small geared hub motor (> 2Kg.) will not greatly effect the handling and can be safely mounted on a alloy suspension fork when installed w/ care. A low power, small hub motor makes for a ...

Re: figuring out the wiring on my new controller

Very strange labeling and terminals. The "electric lock" and "Autometer Signal" cables only have one wire each, so unless you have the "autometer" w/ other feed wires, I suspect they are useless. Like all other controllers, unconnected pairs or groups of wires are out o...

Re: Surplus of blown controllers

I think we should point out for anyone new to ebikes and wondering if their controller will be reliable, that if they stay around the controller's rated level and don't keep changing things, even the cheap, genaric controllers will be fine. It's when the levels are being "pushed" that they...

If by "cassette", you are referring to using a Q100C version of the Cute, that combo is getting kinda wide at 136 to 137 Milimeters. Whether or not it will present some difficulties in the installation depends on the bike and it's chain-stays and drop-outs. Not every bike is built on the s...

I assumed you were talking about LiPoly, since you didn't specify and usually a 10S battery pack would be that chem. But I suspose a 10S batt. could be Li-Ion. It really doesn't matter.

Re: 15s lipo/li ion with 48v controller

No way of knowing when pushing the Values that close. With genaric controllers w/ cheap caps, I've had one that worked and one that blew the cap.
Unless you aren't overly worried about losing the controller, I wouldn't try it.
