I was looking for a new vacuum cleaner a few months ago and decided to splash out and go for a Miele. I liked our previous Dyson but the longevity was poor and the new ones seemed difficult to control with the ball wheel thingy on the back. Miele were victims of the EU change in regulations...

I prefer going off grid to more remote and quieter sites for several days at a time so I've been charging my bikes from the van batteries for the last couple of years now. I hate being hooked up, it defeats the object of the van for me. A cheap inverter from ebay is used, non PSW, rated at...

I learn something new every day. I didn't know that those battery monitors were available. Looks like a common earth just like the wiring on the bike providing one positive is connected to at least one cell. I'll bear it in mind for future reference. Good to hear it's working. Slow pick up...

Not quite sure what you're asking here. If the voltage indicator is the sort I imagine, simple LED constant on type, then I would think a simple inline switch would be easiest. I'd definitely want to turn it off. The current used is small but still can be significant if left on for days at a...

Would you put a picture up when you're happy with it? I hope it goes OK but I'm not expecting to hear it's super fast. Moving and up inclines would be great I think. To the shops or whatever (being useful) would also be good. Best of luck. It's like waiting for the comet landing!

Well done, I'm really pleased for you. Can't wait to hear what you think of it rolling along.

"How did they make it and post it for so little?" I've wondered that too and decided they bang so many things out that they have the economies of scale (there are over a billion people there and the rest of the world seems to want their products) and they don't pay themselves so much. I think...

I understand your thinking about the 13/22 numbers but I think 13 would be too low for your 'thing'. Most common ebike controllers are rated at about 15amps today and are hardly very powerful and for yours I would have thought it needed more, hence the 22. One of the dealers on here said that...

Totally random guess on what you've got and the numbers on the label, it's 36v, 22amp? The number on the bottom right appears to be the company phone number! Just wondering if you have a smartphone and can read the barcode. That might tell you more?

Brushless motors are freewheeling, there's no commutator and brushes to slow them down, but no regeneration either. An electric motor like yours is always connected and is either a motor or a generator. Brushless is different, not necessarily more complicated. But they need a different...

When you say freewheel do you mean rolling on its own? Or is there some mechanism that disengages the motor when not under power. If there's no mechanism for disengagement then the motor is always engaged which is why these were changed to brushless motors? Some oil/grease might help if...

It's a pain waiting to see what's happening and wondering whether it'll come together OK. I was like that when I put my bike together, in the end it took me two weeks for what everyone else tells me is a two hour job! Some unavoidable delays in there and having to go to work didn't help but...

With magnets I've always thought that it's fine to clean them up but the rubbing should be done with something that's not metal. I'd have thought sandpaper/emery cloth was fine. It's the gap between the magnet and the coil that's critical in terms of strength/weakness. The picture shows the...

Been wondering how you were doing. I'm assuming it's a brushed motor from what you've said before so the magnets only have a passive job as the motor spins around, not like a brushless one where they hold the thing together. That said they need to be secure so I'd clean the place where they...

It's a 'thing' of wonder! I can see why you'd be worried about all those washers and nuts and putting it all back together. Personally, I wouldn't worry about a plate yet. When you're happy just running it around see what attention you actually get before that. Around here no one would...

Something else to add to the list: Banggood.com . I'd never heard of this site before and now it's one of my favorite places to browse for stuff. The LED lights are very powerful, the cheap one especially so, but shoddily built. A bit of care, some silicon sealant and the light is great...

I'm not bored, I'm fascinated by what you're doing, but you've got several threads so suggest you keep it all in one place. Here? Others are much more knowledgeable about these things than me but logic suggests that a speed sensor must be present somewhere. The controller could, I suppose...

Not sure they offer a 20" wheel though. Many others out there but BPM motor does tend to be regarded as having the most torque in a legal way here. Not sure about the Med though.

Looked at your link to the donkybike and see it's probably a nexus 3 hub gear change. I've got one of those on my cylotricity conversion and find it's fine for most ordinary hills in a 700c wheel (10 - 12%). Anything more and it's usually a get off and push but I'm 80kg and no dog. The site...

I've been on here for around a year now. I'm not the greatest contributor as I'm still learning lots from all you good people out there. However, I thought I might share some of the gems I've learned, which may be obvious to many, but were new to me, and invite anyone else who wants to share...
