You lot are neurotic, nothing has happened yet and may never happen. .

If the handlebar head unit is labelled 36 volt as you've found, the whole system probably is. The 15/6/29 on the motor may indicate the date made in 2015, the 36 volt units were being sold then. Maybe try asking Helkama for information? .

Are you sure this is a working bike since it is an old model? I'd hate to see you spend on a new battery only to find the motor is dud. Panasonic dont supply any spares, repair is by replacement of the whole unit usually costing well over £500. .

All three are always connected on these units: The centre wire goes through the loom into a motor unit connector on the circuit board and this is encapsulated and sealed into the crankcase half, so no access for tracing. .

They of course had their units to play with, something I never had with the lithium system. A further difficulty is that these had different versions according to the bike maker's requirements. That thread starts with a BH bike with the lower power system and 8Ah battery originally created by...

Yes. Here's the loom for these lithium battery motors showing the three battery connections lower left: Link People across Europe have been trying for years to run these with other batteries, seemingly without success. When Kalkhoff wanted to run them with larger capacity batteries that...

According to a plastics expert I was chatting with a few years ago, the best lubricant for nylon gears is water. Difficult to arrange for them to run immersed in water in our motors though. .

It has to have three connections to operate the motor and four connections between charger and battery with this motor and battery system.

No, it not 3 pins it is a 5 pin system, different pins used for drive or charging. You have to use a correct Panasonic battery and charger only. See this web page and scroll down for pin information: http://www.flecc.uk/p/li_battery.html .

Ian's bike and battery are six years old if he's never replaced the battery, so that would be the first thing I'd suspect in this case. Very few pedelec batteries get to that age still working at all. .

Noise is the biggest factor in hub motors, the nylon gear(s) being much quieter. For example Heinzmann used nylon on their 200W model but steel gears in their higher powered hub gears, having to put up with the noise then. Noise is probably a big factor in the primary higher operating speed...

The second part is correct, the first part is very wrong. I wish the police and indeed everyone else would stop saying pedal assisted. EAPCs are not, they are auxiliary motor assisted, that is what the EA means, "Electric Assist", followed by PC for "Pedal Cycle". .

Yet still dissatisfied, we're now looking for other planets to move to. .

Regardless of where it came from or who did it, this assassination attempt will undoubtedly win him lots of sympathy votes, and Trump knows it and will exploit it to the full. I can't help but feel Trump will end up president once again, not altogether a bad thing internationally. .

There already are such machines. .

The same as always I suppose, ever greater restriction. At 16 very long ago I could get a full motorcycle driving licence with a simple driving test on a bicycle with a tiny motor attached. Compare that with today with an an endless array of m/c licence groups, power restrictions, age...

If true yet another huge advantage. One way or another, the day of the currently low cost privately owned car is over already in the minds of the authorities of many advanced countries. The making it happen has already started but the blinkered car owing public have yet to realise it. .

Excepting the paperwork, I don't agree. Just like the privatisation which happened instantaneously, the instant change of control is just a change of employer for the staff in the industry But it doesn't matter anyway if we adopt the policy of more expensive water as I've described. That...

You really do lack understanding. London has done what it did by raising the money necessary for the huge increases in public transport from motoring. That will work equally well elsewhere as I've implied, but no, you are so blinkered you deny that out of self interest. It is precisely your...

They are both pressing issues, which is why Jeremy Corbyn was right in his intention to renationalise both regardless of the cost. Worldwide rail is state owned, long proven to be the only way a country can have rail. Even those arch privateers the Americans have admitted defeat and have...
