Aha yeah that whole thing with testing hall sensors and stuff is a real headache. Been doing it once before :) This controller has two self learning/intelligence connectors that are put into each other to make it work. Do you guys think it will be enough to check a few different matches with...

So I have made it move now at least. With an external throttle. Had to clip of the cables there a bit to get it onto the controller. It is not generic throttle to jhrak so different interface/hookup there at the cables. Anyway, now it is moving. I am pressing full throttle all the time in the...

You just basically paste that thing onto the motor? To check temp.

I have a kt-lcd3 and a sw900 lying around. Anyone knows if one of them supports this feature of turning down the max current?

I have a 250 watt nominal front hub motor. I have a 48 volt battery and the controller that seems to work best with the wires is a 18max current controller that I have. Would this work or would it fry the motor in a winter barbecue? I am thinking short bursts it could probably be fine now in...

Both steel and aluminium should be able to handle a small drill hole don't you think? So I can fasten the torque arm really securely. I think I will do this. I don't think the wheel will come off if a strong structure like that is keeping it in place.

Yeah thanks. Looking at one of my videos you can see that I have torque washers on the inside there. But maybe I could also strengthen this whole thing with extra torque arms. Just not sure where to anchor them. Maybe on the inside there where the washers are as well? The torque arms you linked...

Yeah could probably grind them off with an angle grinder or something? Yeah motor is quite small. This is not going to have a very high top speed. Will shoot in 500 watts approximately. At the most 600 watts in a slope perhaps. What type of fasteners would you go for? Something similar to torque...

It is too bad that it cannot be used right away, because it looks like the wheel sits pretty well in place between the forks now and it spins pretty well on the throttle. But if you guys think this is dangerous I will either change the fork, or if you think the other fork does not work either...

Ok check this out. This one I had lying around. It is also a budget fork but it has pretty solid dropouts I think. But I don't know if it would work to switch this type of fork with the one sitting on the bike. The vintage type of screws that puts the other fork in place right now are that old...

Yeah, but then I know at least. And I think I will either change the fork, since I have one in mind, but I am not sure if it will fit. Will show you when I get home later today. Or if it does not fit I will probably throw away the frame. I actrually bought this and got hold of a strong big front...

I am trying to send this video where I do the best that I can to film it, while not being able to hold my phone at the same time :) To answer both of your questions, I have what looks like a torque washer on one side and on the other side, where the cable is, the torque washer basically sits...

Is that what it does? I thought those things were only so that the wheel did not come off when extra torque was applied or something. Hmm good to know. So what they also do is to load the fork instead of the dropouts huh? ok But then the hole in the torque arm is the one most important right...

It mounts solidly when clamped in towards the middle via the bolts. But as you can see from my second/middle video above it is smaller in diameter than the dropout holes. So it sits in place via sideways pressure. Maybe a torque arm would be enough to hold this together? So if it gets loose the...

Hmm I have clamped it in with the bolts so I guess it is quite tight. Do you mean an ordinary torque arm that just prevents the wheel from coming of if it spins out of the dropout? Kind of like this simple one here would work...

So I have gotten hold of this used bike and are going to make something out of it. I have been a tinker for quite some time. Anyway the dropout looks superweird and I think the previous owner have welded on some adjuster metal-plates there to make his previous wheel fit or something. Anyway...

So I've gotten hold of an old bike with a rather weird dropout where I think the previous owner has welded on adjusting-metal plates to make the dropout fit his wheel or something. Anyway I need to fit the front hub motor wheel in the videos here. Any idea o how to do it? Is it ok to fit one...

So I have this faulty BMS on my ebike battery. And I am going to change it out. But I cannot exactly remember how I did it the last time. Is this the order I need to do it in? step 1: disconnect main negative of the old bms step 2: solder on main negative from the new bms to battery main...

Hi I have built my first battery pack. In my first video here you can see where I measure from the first negative cell group, which is of course the first lonely negative cell-group of seven cells. There are no parallells going from this negative cell-group, because they start at the other...
