Used Nine Continent (9c) rear motors and Lyen controller.

I've got an old, broken slow-wound (6x10, do about 28mph at 72v) motor and a brand new M2706RD (9x6 winding) bought from Grin last winter. The new motor is laced into a relatively narrow rim and is still in-box from Grin. Pic below. $200 + shipping for the new motor. The broken motor is rusty and ne...

Best value 18650 flashlight: ATACTICAL A1

Just thought I'd share that this flashlight is great. $20 comes with a quality battery and charging cable. Battery and flashlight perform far better than anything I've gotten for a similar price. Specs seem legit. 220 lumen mode is brighter than all the "900 lumen" flashlights I got from Deal Extrem...

Re: Finding good quality V Brake Pads

I cannot for the life of me get the Koolstop pads to stop screaming at the top of their lungs. Are there any other options out there?

Re: Epic rim failure. Why?

Ah, dampening, good point. If this had happened on the back instead of front I would have been able to steer better and maybe stay up longer, but I think anyone would have to expect they're going to go down if that mess is hanging onto their back hub. Anyways, the main moral of the story here is to ...

Re: Epic rim failure. Why?

Whether its 2WD or just a single hub motor, I don't like the Direct Drive (DD) hubs on the front. Aluminum rim with a double-wall for strength, stainless steel nipples... This was a double wall aluminum rim with stainless steel nipples It was obvious that it would fail, long before this happened. Y...

Re: Epic rim failure. Why?

Hitting hundreds of potholes with a front DD hubbie is sure to have that result eventually. Get a better headlight and dodge the potholes. I'd imagine it'd be more accurate to say I had hit thousands. It is not really reasonable to avoid them here due to the quantity and having to share the road wi...

Re: Epic rim failure. Why?

Okay, I think I know what happened, spokes got loose. There had been a subtle noise coming from the front that I thought was maybe due to worn out bearings, but now I realize it was probably the rim shifting a little due to the spokes being loose... Never realized it was so important to check on the...

I remember that! yeah, you've been rocking the same setup for too damn long, buddy! :lol: Hope you weren't hurt, that looks nasty. Aluminum bits do have a finite lifespan.

Yeah, it's almost 5 years old. Same bike I had when I took a ride with you in Beaverton 8)
Pretty sure the spokes are a larger gauge than standard though

Re: Epic rim failure. Why?

I'm really confused as to how the front rim could be the one to fail on me. The back rim is just from some $150 Shopko bike and obviously there's way more weight back there since there's no suspension back there and I have a 20lbs battery on the rear rack. And the rear tire has gotten way more flats...

Re: Epic rim failure. Why?

The tire was basically the same width as the rim. There was no noticeable ballooning. Hard to say, a multiple spoke failure could have also contributed...Are all the spoke heads, spoke shafts, and nipples intact? I might check on that when I'm less sore tho I think a lot of the spokes took quite a b...

Never a pinch flat. I think only 1 flat tire on the rim in 4 years. Tire is actually only 1.95" wide when inflated.

Epic rim failure. Why?

So I was cruising a long last night and went over a pothole not any more gnarly than any of the hundreds I've gone over before and then all the sudden something clearly had gone terribly wrong. I was only able to keep the bike up for like another 30 feet before going down. When I got up, the front r...

Re: Ping charger failures

Whoops, yeah didn't even have the ground wire connected at all. Checked the big 200V capacitors like the one that has the "QC pass" sticker on it, but they were still fine. Were those the ones you were talking about, or are there other capacitors I should check?

Re: Ping charger failures

i have parts but cannot even make out what you are referring to. In the picture there's a component that had a pretty epic failure just below the big capacitor with the "QC pass" sticker on it. I replaced all the damaged components already and it worked for a minute before failing again and now I c...

Ping charger failures

Welp, both of the Ping chargers I own are broken now. This last one at least gave some clues to what went wrong though (https://flic.kr/p/rwypL3). I replaced the obviously damaged components and it worked for about a minute charging the battery before I heard a spark and saw a little smoke and it we...

Re: Ebike towing a bike

When I ride with non-ebikes that want a boost up a hill, I just ride up next to them, put my hand on their back, and push them up the hill. Can't really pedal while pushing though and there's a limit to how steep of a hill I can pull it off on. Similar limit to what the power of my setup is capable ...

Re: No longer able to charge. Charger or BMS?

Great success! I ended up soldering the gate and drain legs into their usual circuit board holes and building a fat bridge of solder between the mosfet drains. Thanks for the guidance!

Re: No longer able to charge. Charger or BMS?

Hmmm... the heat caused the surface of the circuit board to come detached from the backing, so it came off with the mosfet. Seems like I need a whole new BMS, no?

Re: No longer able to charge. Charger or BMS?

Btw, if something doesn't work out, it's fine to bypass the BMS and connect the charger directly to the battery to get a charge, no?

Re: No longer able to charge. Charger or BMS?

Welp, it's definitely the BMS. I have a old BMS that was DOA when the battery was shipped to my friend. Think had the same problem of not charging, but I was thinking the discharge mosfets on it are probably the same and I'll just harvest one of those to replace this failed charging mosfet. Now to s...

Re: No longer able to charge. Charger or BMS?

you can test the charging mosfet with the diode tester on your DVM. if the mosfet is getting hot, it is shorted. mosfets do not usually get hot when functional. Yeah, thinking about it, that seems to make a lot of sense. Strange thought that my friend's got so hot the plastic on the mosfet melted a...

Got back from work today and my 3 year-old cheapo 48v lifepo4 charger wouldn't start charging the battery. It is still putting out 60v. The charging FET on the BMS for my Ping battery melted off the plastic a few weeks ago, but it's not nearly as melted as my friend's whose Pings both did that when ...
