Both those indicate the voltage under load is not being as well sustained as from the genuine article. This is likely to show up as soon being a somewhat lower capacity than specified, exactly as another purchaser found with a similar Oriental substitute battery. At the price you'll probably...

I've got plenty of knowledge of old e-bikes, but this one is completely new to me. I'd say definitely continental and the styling looks like it could be French as you may recognise. However, that direct drive motor looks like it could be the one used in a Mercedes Benz e-bike some years ago...

But that's operating temperature Trex, much cooler is better for long term storage, preferably almost zero degrees C if possible. However, I accept that just the amount cooler we are usually able to manage doesn't make much difference. .

The Panasonic unit is 250 watts and has it's integrated battery, that Heinzman front hub motor 200 watts. I guess they could only run at the same time if the generator fed the Heinzmann directly since that Panasonic 24 volt 6.5 Ah NiMh battery couldn't begin to power both motors. I don't know...

It's been done but is still illegal since it cannot be shown what power the bike is using, battery or direct from the generator. There's also a restriction on manufacturing on the public highway, electricity in this case. Here's a twin motor example, a Panasonic unit crank drive Lafree with an...

Some designs use an intermediate idler sprocket to deflect the chain path for similar reasons. In another variant, a Cyclone or similar motor is placed part way down the chain path to add drive power at an intermediate stage. .

The small front sprocket probably has enough wear for the teeth to be hooked. They could then trap and carry the shorter new chain links around the sprocket, the hook not being able to let go at the feed off point. A new sprocket with the new chain should cure it. .

This is true of any battery type, it's called the Peukert effect or Peukert's Law. Explanatory link .

You've been watching too many car adverts where a car winds along at speed on a clear road in amazing countryside without any other vehicles, crossroads or traffic lights in sight! :) But yes, if you could find the conditions to work one really hard all the time (Le Mans?) the batteries would...

Tesla's case is somewhat different where battery use is concerned. With our minimal batteries on e-bikes we are working them quite hard nearly all the time, so they suffer in consequence. Cars, including Tesla's, due to road and traffic conditions spend most of their time running at only a...

South Africa totally lost control of crime decades ago, their freedom from apartheid has proved to be a very poisoned chalice. It's so bad that the only chance of correction is probably to have a rigidly controlled undemocratic police state for a while. .

Given the length of development through experience that's also necessary, I think Toyota are to be praised for starting the process as soon as possible and in parallel with hybrid. Clearly we will be unable to very widely adopt hydrogen as a fuel for a very long time, simply because the only...

I know Rob, it has to be initiated by the politicians, but unfortunately they are too scared of saying anything that might be construed as discrimination. So they let the deaths continue rather than do anything I'm not so scared and I don't want to see so many women continuing to lose their...

True Rob, and long ago I watched in disbelief a video of another case where a woman cycled rapidly past a huge left flashing indicator on a truck waiting to turn left just as it was setting off. She was crushed to death, the truck driver having no chance of seeing her in time. There clearly...

It seems with this car that Toyota disagree, and so do Mercedes on the group of eight Hydrogen Fuel Cell Powered London Buses which have been running successfully for over four years now: They also previously ran during a three year trial from 2004 to 2007. . .

And as I so often point out, the majority were as usual women, three out of four this time, despite women commuters being very much the minority. Ther's no official figure for the ratio of female cyclists, but from my London observations I'd say they are less than a quarter of the total while...

A hub motor can be specifically designed to be a full electrical brake as well, and three years ago Panasonic released one such e-bike in Japan with 3000 of them as a trial launch, the front hub motor being the only front brake. I've heard nothing since and they've never come out of Japan. .

You were wise to avoid confrontation, modern life is increasingly producing extreme and violent reactions, sometimes prompted by mental illness. The force that might have become necessary if you had taken direct action could well have resulted in you being arrested on suspicion of an offence...

Don't bother with a plate Craiggor. Not only have almost all manufactured e-bikes not had them, the new law EU style that's about to be introduced this Spring doesn't specify them in this way. They just have the usual CE markings etc on manufactured bikes, and you can't legally make those...

Yes, that's the fourth one this year in just 50 days, on target for many more London cyclist deaths than ever before in one year. And once again it's a woman. They are greatly outnumbered by male commuters but somehow usually manage to make up more than half the deaths. Part of the trouble is...
