Not to be an insult. Just have to ask. When you adjusted the headset, you did loosen the side screws on the collar first. If you get really desperate, rotate the tires,

I changed my own oil for decades. Everything else too. Last brake job was 2009 on my Audi. That's not being green. It's being cheap, but it was also fun. Tell your car buddies that you're swapping a motor and you get lots of help. Just have pizza/beer afterwards. These days. no more heavy...

Franz there is no way you can reverse the leads on a pedal sensor. Quit reading junk from whoever said that. It's not like a mechanical light switch. It's an electrical circuit with two wires for power and ground. A third wire is the output. It runs by reading magnets spinning around the pedal...

I replaced the 36V Silverfish battery in my Ecotric with a UPP brand off amazon. Everyone hates UPP because their triangle frame batteries are banned in US and UK, but their standard case batteries are made as well as any other maker, and are available with Samsung cells at extra cost, I;ve...

Some discussion shown for just swapping wires. I have tried it, and it works, You have to swap two phase wires and two sensor wires. Could be done by switches, but you want to stop and shut off power, https://goldenmotor.com/SMF/index.php?topic=6071.0 Also, this chart suggests switching the...

I made a home made press out of 3/4" threaded rod, several 3/4" nuts, washers, etc., I used it to push in the bearing cups on several bikes. I also used it with a piece of pipe to press in a really stubborn crown race bearing, Wait, no one presses in a crown race bearing! After I was done, I...

Next question. How many wires go to the motor? -If it is a sensored motor. three thick phase wires and 5 or 6 sensor wires, A Bafang uses 6 sensor wires for a total of nine, -If it is sensorless, then only three phase wires and 3 sensor wires. A bafang motor may use a round 9 pin plug in...

Yes, I remember Heathkits and tube amplifiers, I built a Knight kit amp, but only one channel, No stereo. Neither Robertson or I want to see you get in trouble. so I don't endorse tearing into the battery, but I would like to know what happened. You said the bike powered up. What caused it to...

I don't ride ebikes to be green. I ride them because I'm old and they make it easier. I repair my own and I'm not particularly green either. I do save all my old bike parts, as they are often reusable, like handlebars, seats, brake parts, etc. Things like steel rims that no one wants are quickly...

"Hi Harry, my electric tricycle has a hub motor and is only driven with the throttle on the handlebars, there is no PAS installed as it has no pedals. It would be useful to know which brand and model of controller is equipped with the cable that allows you to change the rotation of the motor. Do...

Etrailer.com only shows a Class 1 hitch for the Camry, but sells a Class 1, Class 2, or Class 3 for the Suburu, I would suggest the latter if you're carrying bikes. You get a higher tongue weight rating for the Class 2 and 3. They rate a Class 1 as good for 200 lbs, but that is right at the...

Wow. I didn't even consider battery logistics. It's being able to get around in a place where your money don't work, no one speaks English, and your stomach is upside down. Again, quite the adventure and well done videos.

Sorry Franz. You cannot flip the PAS sensor wires. Whoever said that was wrong. What a goof. That won't work. In addition, only certain hubmotors will reverse direction. Those hubs have no internal gears. Motors with reduction gears can only power in one direction, and if spun backwards, they...

Those are commonly available silverfish batteries, so you could consider a new one for the Hammer. These are both 48V batteries right? If your folder is 36V and the Hammer is 48V, you can't swap batteries and use that as a test. But say they're both the same. I don't see why the folder battery...

I considered building an ebike battery with Sriko cells, but the capacity is so small. The battery would be almost twice as big and have half the AH. Tough sell. The Hidaki cells are 25% better. When they get another 25% improvement in capacity, I think they will take off. Meanwhile, I see they...

The question is interesting, but why worry? I assume the motor designers built them to run at biking speeds, between 10 and 18 mph Heat is what wears out electrical components, so keep the current low, and the parts are happier. While you have the question of efficiency, you have to trust...

That's a rear rack battery. It's only held in by the connector and keylock in front. It should come right out. Pull harder? Sometimes, if you look up at the bottom by the ke.. you will see the hole where the piston from the key fits when locked.

I'm not aware of any KT controllers that are dual sensored/sensorless. As far as I know, they come without the hall connectors, are square wave, and they tell you in the listing it's sensorless. But what do I know. If you got one that is dual mode for both types of motors, I believe that the...

Couldn't find any more Velowaves at walmart.com, but there are a few others that are similar, One or two came with LCD screens, which may help the feel of the pedal assist. The biggest tradeoff on low cost hubmotors is the three level pedal assist used in their controllers. It's usually set up...

Sounds like a weak battery. Might have one cell group at low voltage. When you try to pull a load, it sags and shuts off. Do the controls on the bike shut down and go dark when you lose power?
