Yes, I have one. No video. Tech specs: 6T rear Mac (EM3EV) with 7speed freewheel laced by myself in a 36 spokes 24" HALO SAS rim with a 3" Wildlife tire around it. 12FET4115 Lyen controller limited at 50A CAv3 in power throttle mode, two presets: (1) 800W max and (2) 1900W max 50V 15Ah Li...

Get the correct thread die (probably a 1.25 M/M) and thread it on the axle first (w/ lot's of grease). Cut the axle as sharp and clean as possible and if it gets ragged, flat grind it w/ a hand held grinder. Then you can work the die off to clean the threads. Turn it back on carefully (start it by h...

Yeah, I always start w/ older FS mountain bikes for my road going ebikes. Best value in Ebiking! ...but I figure some rear suspension would be nice for high speeds and long distances. Especially if you don't change that seat:) Another thing you might want to spend money on are better pedal gear-sets...

.... my existing controller overheats after about 1k feet of climbing while the motor isn't even warm, so I'd like a higher amperage controller. I doubt your controller is overheating (too hot to hold in your hand?), because my experiences w/ Q100 C's and H's is the first thing that really overheat...

A lot of bikes have two sets of water bottle lugs, the second set on the frt. of the frt. down-tube. The batt. might look like it will be too close to the tire, but mine have never hit.
The other option is to install new screw-lugs. It takes a kit to do it, but any bicycle shop can do it.

Google is your best friend. Looks like that is for fat tire bike only. Only 32 holes also. https://www.aliexpress.com/item/32874325686.html https://www.aliexpress.com/item/32874325686.html Maybe a 20 to 30 Amp controller. You don't need to worry about controller phase, getting it laced in a wheel an...

The most important thing is to always keep it at storage value and only top charge it right before going out. I agree with everything you said except this... for hobby king packs. Dont need to charge right before, hey, a well used lipo is a happy lipo.. only if they sit for like a week or more do y...

In order to know how much juice is left in my packs when I ride, I make sure I don't go under 44v (20% capacity). With these low cells I have now, what voltage should I look for to stop riding? 45v? 46v? Don't want to do further damage to those low cells. When I ran 12S, I relied on my controller's...

I've read about electric motors performing poorly at low RPMs, so just going slowly sounds like it might be counterproductive. Very perceptive as this is the crux of the matter w/ hub motors. A common mis-understanding is when folks equate an electric motor w/ a gasoline engine. The way the two pro...

I got a message back from Grin. They said that the blinking light indicates a brake circuit fault, which is different than what the manual says, I unplugged the tripwire and the problem is still there. The brake fault makes no sense. It can be dis-connected and it's out of the loop. Time to break o...

4.22v!!! My God, the LiPoly Over-Volt Police here will be outraged! Seriously, you don't give us much info, like what charger, but if by " parallel balance charging ", you mean charging 2) bricks at the same time w/ a parallel board, I would simply suggest you charge them one at a time and...

And BTW, hub motors are not "a thing from the past". For a rider who does not need a "wide performance range" that the mechanical leverage of a mid motor set-up offers, hub motors work fine and are more trouble-free than system that runs though the bike's gears. I think the compa...

I've run a couple of geared mini-motors sensorless and here's my take. Some work ok and other combos didn't work at all. It depends on the controller's ability to "sync up" with the motor. I believe this is a function of motor speed, mostly because my "fails" were w/ Q100 motors ...

So, is it really absolutely impossible to have strong knock proof finish using rattle cans? Are spray guns really the only way to go if you want a truly durable finish? This is correct! You can get a decent coat of paint out of a can, but you can't apply an automotive clear out of a can. Actually, ...

False equivalence argument.
Those countries are not in China's league when it comes to malevolence.

The other thing is, a Pew Research Poll (hardly a right-wing entity) show that 66% of Americans have a negative view of China and that was 5 days ago. Walmart and others may be forced to rethink their sourcing. I can't put myself in others position, as I said, I'm retired and the economy crash doesn...

It the stuff we are getting from China really a bargain? If I buy a $100 motor, it costs me up to $150 to get it shipped. Couldn't, say Mexico, make a motor that might cost $50 in parts and get it to the States for less than $250? I certainly wouldn't want any pressure put on the vendors here in the...

Recently, I posted that I am not going to buy anymore Ebike stuff from China. I didn't imply that folks here need to follow suit, I was just stating what felt right for me. I was excoriated by the China apologists and they attacked me as being "stupid" and having "wet undies". Wh...

It's hills that really suck it out of your pack.

I Googled Magic Pie 3 bearing replacement and the first thing to come up was;

There's more if you care to look.

Or for those lacking machining skills (or just plain lazy), one can just buy the V4 T.A. from Grin.

Has worked on every application I have tried it on.

I know this sounds counter-intuitive, but you probably should make sure it's not an electrical, specificly the Hall and phase connections. Often, when the one or more Halls are disrupted, an otherwise good motor can free wheel, grumble and do other weird things. For a quick ck, you don't need to any...

Except possibly a flat washer between the end of the spline and the inside of the drop-out, you don't need any kind of spacer to install the 7-gear cassette. Swapping cassettes doesn't mean they have to be exactly the same width. I'm assuming the 7-speed has a 13T sm. gear. Do yourself a favor since...

Dman is right!
The TW200 is, and has been a very popular bike. The fat tires make it a foo-foo bike in soft terrain "par excellence".
Plenty of junk motorcycles lying around that don't have the value (even not running) of the TW200.

I've shipped a bike overseas. What I did was to go to a bicycle superstore an ask for an empty shipping box before they knock it down. I spiffed the guy who builds the bikes to more or less keep it intact by cutting it at the bottom. For you maybe a fat bike box might work out. All I had to do was t...
