the motor weighs 1.9kgs on its own, battery + controller 3.1kgs, cables + LCD about 300g. the total bike with all the electrics would weigh about 19kgs.

I can't imagine anyone selling a kit that is locked. of course it's unlikely to be enforceable but this is a moral question for manufacturers and sellers. Assisting possible offenders? You may just as well ask the same questions to members who assist the same possible offenders with their expertise.

Let's deal with this methodically, one bit at a time. It's clear that changing the settings of the bike is illegal but we are not talking about that. We are talking about bikes compliance with regulations. it's clear that when the bike is delivered, the customer cannot change the speed...

we all have our personal views but if you take into account the greater good of interoperability and freedom from single sourcing for hardware and services and accept that the guilt is with those who break the law knowingly, regardless of the means, then the end product is likely to be cheaper...

LCD password is 4 digits, each is made of a number of key presses, so between 8 key presses and 50 key presses and yes, it can be set individually. Once you accept that LCD should be locked, then we can move on to the next point: If it's clear that the guy who replaces his passworded LCD is...

you have to have proprietary systems for that. If you want interoperability, then those who want to derestrict will simply by a replacement LCD if they don't know the password. If you say 'then it's OK if the guy wants to buy a new LCD', we can move the conversation on ' how difficult to guess...

if you can upload firmware either through a USB port or the LCD connector then it can be bypassed. We should examine the differences, or not, because a defeat device if it does its job then there should not be any difference whether the defeat device is hardware or software or a combination of...

flecc, the LCD has password protection. I try to steer the conversation toward general acceptance that the LCD password is necessary in keeping the bike legal. From then, move on to whether the removal of the password equals to fitting a dongle.

SW, it's just a password. Most LCDs can have their password set before delivery. You would be then obliged to turn off or unplug the speed sensor to obtain assistance regardless of speed. So the discussion is: does the removal of the password make the bike illegal?

let's just ignore the context of a physical switch because there is no switch. Let's discuss the difference between a physical dongle and going through a menu tree to change the speed setting. Both mechanisms cannot be performed on the fly. You have to stop the bike and do it. So it's clear when...

but there is no more 'off road' switch. The off-road setting is obtained through increasing the maximum speed setting in the LCD.

the lack of tampering protection is obviously a concern. If you can turn off the speed limiter by twisting the magnet or the sensor head so that the sensor no longer detects correctly the passing magnet - are your fingers then considered a tool? If they are, then what's the difference using the...

some plastic cups are hard to shift. The left side, non drive side, has normal thread, first to be removed. The right hand side, drive side, is also called the fixed side because the cup is permanently connected to the right hand ballbearing, has left hand thread (reverse thread) and to be...

Bafang charge 20% more for the same thing but their quality control is the best among Chinese motors.

Some people are natural athletes most are not. you know as well as I do that the power of her input is directly proportional to her cadence and torque. I rode the Woosh Faro fitted with the torque sensor for the best part of a year (I still have two of them in stock in case anyone is interested)...

woosh bikes do cycle to work

you'll need to ride a German bike to go that low on battery usage because they have ways to make you pedal harder. The lady has a slow cadence, that says to me she is not a strong pedaller. 10WH / mile is more realistic.

the US has an election in November, there is no way anything can be done before XMAS. we won't have a proper deal with any of the largest economies: EU, China, US, Japan, India for a few years yet. Not only there is no time, there is no real incentives either because until we know what we want...

PSBR for this financial year is estimated at £332 billions. That's roughly £5,000 per person in the UK. Next year's PSBR may be less thanks to import duty (which goes to the EU at the moment) but will still be very substantial. Perhaps a wealth tax on the UK's non-domicile residents.

yes.
