    BYD Seagull, the cheap electric car the USA almost got

    Sometimes stupid cures itself, but we get around this by making more stupid. People can and do use enormous resources to avoid admitting Reality, all the while insisting they are 'right'. They run out eventually. Sometimes I'm around and I get to enjoy it. Reality doesn't care, and always...

    Source for 5083 25mm or 1" tubing

    There is no need to reply suggesting I try Alibaba or something. I would like to hear of A SOURCE that CAN PROVIDE Alumin(i)um tubing: 5083 alloy 25mm or 1" O.D. Modestly larger sizes can work. 2 or 3 mm wall thickness I'll want 8 meters but I can negotiate that with the source. I can...

    Middrive, belt drive and coaster brake

    This sounds real - you can space the components as you need to ensure the belt line. I am not certain of the other remarks about the consequences of belt drives. My reading suggests a Gates belt will last for 20k kilometers. As well, I see Gates sells snubbers and tensioners for belts which...

    Middrive, belt drive and coaster brake

    If you don't use all of the sprockets, you can mount a belt sprocket with spacers anywhere along the freewheel/freehub to buy more adjustment room to match a front motor sprocket line. Gates belt sprockets to mount to a Shimano 9 spline freehub are standard parts. There are even some rear hubs...

    anyone had a battery that wont switch off

    Yeah, but he's miles away by now... It was a pretty big battery.

    Middrive, belt drive and coaster brake

    A belt means you are giving up flexibility for the belt-line. Chains bend sideways - belts do not. You'll want to investigate the 'chain line'/'belt line' of your motor and destination rear hub. Gates recommends a millimetre of difference at maximum. My trike has a belt from (mid mounted...

    Amberwolf disappearance and newbie help requests :(

    I have read the post Amberwolf wrote, and I don't read anything that isn't an actual statement of fact. I do have my own experience giving and receiving that without tone and context from actual presence that communications can read differently. But I don't like the thought of Amberwolf tying...

    BYD Seagull, the cheap electric car the USA almost got

    Absolutely. Cars take a ridiculous share of space, and other resources for most of the jobs they do, and they isolate people socially, which encourages anti-social behavior. The solution to building the wrong society is not to make it less expensive, the solution is to stop having that society.

    UK gov' consultation to allow higher power ebikes and throttles

    They aren't, so that's not part of the discussion. Electric boost beyond that speed may be limited (25Km/hr) here in Australia, but you can pedal your bike/trike as fast as the speed limit where you are riding (roads and shared paths have speed limits).

    Help with GMAC superharness rear hub order

    Grin sold the properly machined metal mounting plate/heat sink for the controller. That should be part of your order, and I don't see it on their website just now. I only see Reention mounting plates and external (bike frame) mounting plates. You want one - it soaks up extra heat and connects...

    UK gov' consultation to allow higher power ebikes and throttles

    Wow. It's almost as if we had some responsibility to other people for our actions and the consequences.

    UK gov' consultation to allow higher power ebikes and throttles

    Yes. Since this was here, and a good discussion, I wanted to leave explicit information for DIY folks that the 250w didn't mean 'maximum at any time no matter what'. When I started, I thought it did, and I would have not purchased the same motors if I had known better.

    UK gov' consultation to allow higher power ebikes and throttles

    I understand the Aussie law is modeled on the European ones. The UK details might be helpful for someone assembling their own. There is a detail I've learned about, which may or may not fit with UK law - '250w' does not mean 250 watts maximum. Rather, it means that it fits some testing...

    UK gov' consultation to allow higher power ebikes and throttles

    If the law in a jurisdiction specifies you can't change the controller, then such a change is illegal. Depends on where. I'm in Australia, and among other requirements, on public roads and paths the motor must cease providing power at speeds above 25km/hr. If I change this on a bike, I'm...

    Universal AWD mid/front hub bike

    This helps as it provides some idea of the sort of riding you want to design for, although it also seems to say "everything". That's not quite true - it doesn't suggest extreme off-road or high-speed on road. Are you thinking of regenerative braking in this design? I've converted a 20" wheel...

    Your Whours for kms

    I don't disagree with what I think you are saying, but I do have an observation. It tells us that it is attainable. True, the less detail the less that counts for. In my case I added that mine comes from input controlled by pedaling, my motor type/size, some about the size of my vehicle and...

    Reverse thinking...

    You may choose this for your own reasons, but I suggest an alternative. There are many good reasons to design our towns and cities so that walking and other short travel suffices. For use in the distorted cities we have (and between them) high speeds may be useful, but living this way...

    Your Whours for kms

    Mixed riding, hills and flat, motor stops supplying power above 25km/hr - around 7.7 Wh/km for the Greenspeed Magnum Big Wheel trike in the signature, with a Shengyi SX2 fast-wind mounted as a mid-drive with a 26T sprocket on the motor driving a 48T sprocket on the rear wheel. Per Australian...

    Why touchscreens are in every new car

    Putting the controls through a screen means it can be hacked. Can we build such a system that is more difficult to hack? Or course, but so what? Manufacturers will not do that - it's not something they are rewarded for doing (or punished for not doing - yet). The control system must be...
