It looks like the motor is a 9C or a 9C clone. It's a popular direct drive (no gears) motor that is not very expensive. It's hard to tell from your pic, but the wires where they exit the axle don't look too good. They aren't damaged are they? To add a connector, the extension, which has a female end...

My current rig is a 26" Full Suspension Giant Anthem bike with a BMC Rear hub motor, 72A Lynn controller, upgraded torque arms and 10Ah Zippy lipo pack consisting of 4 5000mah 25c 6S packs. I put 2 in series and those two in parallel to make a 10ah 12s pack..... .......This setup has plenty of torq...

It seems that there is a gap between the low-cost chargers and the Satiator. The Mean Well HLG series covers that range nicely. I just ordered a Meanwell... ...It should not be very hard to add charge cut-off to the voltage/current add-on box either. It is built into the HLG, once the set top charg...

You have left out so much info(including your profile), that it's hard to make a specific recommendation, but one thing is for sure. The cable from the motor does NOT go to the battery. It goes to the CONTROLLER, which receives power from the battery. A commonly used connector is the 9-pin ebike cab...

On my Cutes running 20 Amp controllers, I barely get any sag at all, yet they don't have the "punch" of my Turnigy's. They stay about the same until they are discharged past halfway and then they start to drop off. They are perfect on an "assist" bike where system power is not too important. In fact...

It's not a case of the Multistars being "good" or "bad", they are designed for a specific application I've been using Multistars since they came out and they are great for those of us who don't need high discharge rates. What we get are a smaller and lighter pack, low price and a low volatility fact...

You are over-taxing the Multistar. It is designed for low discharge rates. If you are seein g more than a few Volts sag, you have the wrong batteries. You need at least 25C. I recommend Turingy.

My two donor mountain bikes came w/ 44T and 46T big chain rings and I replaced those w/ 48T and 50T respectively. W/ the same chain, there is more tension which helps to keep the chain from coming off. On the 50T big gear, I fitted a plastic "chain guard", which not only keeps my pant's leg from get...

Concerning #2-Although I removed the frt. deraileur, I left the smaller chain wheel on the bike(I actually use it for mounting the PAS disc.)so in the event I would have to pedal without power I can fit the chain to the lower gear by hand. That's plenty of low gears, but I haven't had to do that yet.

Thank you for taking the time to give your thoughts. I've been riding assisted handbikes since the days when e-bikes weren't even a thing, and just for garden shed hobbyists, I do know what I'm doing in that respect. Being a quad and having limited arm function (only about 50% of the muscles functi...

Must be time for a photo! Here's how things currently stand: https://image.ibb.co/cTVxMJ/bike_small.jpg My goals for this build were for a lightweight/discrete commuting bike that could assist me to increase my average speed. Is it lightweight? Total added weight was 7kg, so I hesitate to give myse...

I haven't decided on what motor to use yet I'm still gathering info, but probably whichever Bafang is most suitable of a MAC motor. I'd prefer a 10, 11, 12 speed so that I can keep my cadence consistent without big jumps between the ratios. My bike is a clip-on that attaches to the front of my whee...

Not aware of anyone building a set-up as you are describing. As far as bicycles are concerned, we get a lot of new builders who plan to pedal w/ the hub motor off, yet it doesn't usually doesn't happen. Once 10 lb.s of motor is added, plus the battery, it just is too much of a chore to go it alone. ...

https://endless-sphere.com/forums/download/file.php?id=225219 What is that thermos bottle looking thing hanging from the downtube? I've been meaning to ask every time you post a photo of this bike. If it's a battery, was it a DIY, and if so how? Yes, it's DIY. Here's the build thread; https://endle...

I have never had any luck running a Q100 sensorless. I believe it has to do w/ the fast speed the Cute's rotate, the sensorless module can't sync up. If all you are looking for is a simple low-cost smooth controller, I would recommend this one from Elifebike's Ebay store; https://www.ebay.com/itm/36...

Looks to me like you only need to contour the bottom (Top) of the drop-out to conform to the axle.

You want to tear into a new(and expensive, no doubt) motor and start unwinding copper? I think you will find it to be more of a chore than a fun project. Especially when could just reduce the Voltage to 36 V and be at the speed you want w/ little loss of efficiency.

I've been using 2WD for years and I'm afraid folks miss it's biggest advantage completely. It's not traction, although unless one is an aggressive and routinely lofts the frt. whl., it works well for moderate TRAIL riding. And it's not system redundency, although if I ever had a system failure, I gu...

You still want the best gear ratio(Lowest numericly)that you can get even if you are not shifting thru the gears and that is an 11T sm. on the free wheel and as big a chain ring as will fit. W/. a mountain bike like I use, the largest chain ring that can be used is around 50T and since the largest g...

Your screen name "hits the nail on the head". There's been a number of Thunder 1220's that have died that have been mentioned here. Mine only lasted two years, but that is longer than the Hyperion 1440 that I had before it. I suppose you could try and repair it, but I'm not aware of anybody here who...

Turnigy silicone wire at Hobby King! All sizes, all colors.
Luv the stuff.

I went DIY tubeless on my 2 WD a couple of years ago and so far, all is good. Admittingly, it took several tries to get them just right. https://endless-sphere.com/forums/viewtopic.php?f=3&t=71203&p=1076342&hilit=tubeless#p1076342 My most recent set-up is Crazy Bobs run tubeless and these days, I've...

Although I'm on PAS almost all the time(I use the throttle to mount the bike), I rarely shift on my 2 KW 2-W.D. I start w/ the frt. mini(Cute) because it has more torque off the line than the super smooth, but sedate old Ezee V1(It's the classic car of hub motors, understressed and stately). But I'm...

"Can't see the forest for the trees"! It's hard to tell a motor from the serial #, they don't seem to follow any "rhyme or reason". From what I can tell, it appears to be a large mini, like the FX07. If that is the cover side and that line is a seam, it opens like the other MXUS mini's. That is, the...
