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 ...

Re: Rad Power hub motor bearing replacement

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...

Re: Buying first system - Need input please.

As far as leaving the bike out in frt. of stores while shopping, it's probably better in L. Amer. than in the States. There is almost always a security guy in frt. of stores and although the ones working at the big chain brands can't take any money, I would usually spiff the guys in frt. of the sm. ...

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 of the system. Connect the wire...

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 fail.

Re: cute Q100 casette width

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 same jig an...

Re: correct controller for 10s lipo? will a 36v/48v ebay one work?

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. At any rate, your last post doesn't make sense. If you read my post, you will see I told you a 36V/48V controller ...

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.

Re: Reducing controller's current

You can grind the shunts down w/ a Dremel tool, very crude and you don't really know where you will end up unless you can measure Amps and go in steps.

I lived in a beach town in Mexico for a year and I converted my ebike to a "boardwalk bike". Since there were people walking around, my speeds were really slow (like 15 mph max.).

Re: Cheap ebike kit for paragliding retrieve

It's always best to keep the climbing speed at least half of the top speed w/ hub motors. Too low put's the motor in an inefficient zone that produces more heat than locomotion. It can also be hard on controllers and phase wires as the controller tries to supply max Amps.
