After careful measuring, perhaps the removal/dismantling of the 4 pins, may reveal a way to get rid of the two not needed. At worst, you may possibly cut two off, but watch where the filings go! I assume that two will still make contact!! The usual reason for 4 (2 x 2) pins, is to make sure that...

They can use either of the ones mentioned, as long as the area on the PCB can accept them, but the original manufacturer might use something in the range of 36 volts (guessing), as they are probably a tiny bit cheaper for him. But as long as the working voltage is higher than the actual voltage...

Good to know exactly, thanks. Andy

If the deraileur is worn, or if just the chain needs replacing, that might explain the problems you are having. On my first e-bike, after 3 years of fairly heavy usage, I was on my second chain I believe, and was advised to replace the cassette as well, which solved the problems I had had...

Do not make the mistake of assuming that electric motors are similar in any way to motors that burn say petrol or diesel, especially with regard to torque and RPM. A stalled/stopped/braked DC motor, is still developing a torque value if power is being applied, and assuming that the controller is...

Hubs have less mechanical losses. And no single point of failure. Andy

I did!

It would still be a risk, even if only 50/50..... I saw here what happened to the Germans who got caught out! Maybe the German customs take their job more seriously? Just guessing. Andy

You neglected to mention that it was left over stock, as they offer various versions usually, but because of COVID, that has changed, and not only by them of course! That one will most likely be illegal in the UK and Europe, as it will probably have the more powerful 350 Watt motor that they...

Who are you talking about? If you meant Stark Bikes, you are converting the US Dollar very badly to UK pounds.....why? Do remember, that only one of the offered Bikes is fully legal in the UK and Europe, the one with the 250 Watt motor, for US$399. Though it might be possible to get one of the...

Thats why you got an honest answer back from me! I expect the bikes are also available here, but I myself have never "noticed" any e-bikes from them, so unable to help. Andy

I live abroad, I do not shop at Halfords very often, and many here on this Forum, say they give poor service. It appears to be true! Is that clear enough for you? Andy

OMG!!! I have started to understand better the Halford's problems..... Unbelievable. Andy

:):cool::D

That will change once COVID is gone and production ramps up! For any good Home DIYer, cheap bikes are still available, like here:- https://starkdrive.bike/ This is a solidly built, Chinese standard bike types, with many possible extras. One must take into account import duties and Transport...

Sadly, a valid reason to ride something more "cheap & cheerful"...... Andy

Good point. For safety reasons, the voltage written on the caps should be far higher than the battery voltage. For 36 volts, I would recommend above 60 volts, and 72 volts should preclude failures, for example. The replacement of a controller, is for a committed DIYer, no Biggy, but for someone...

Very interesting reading. Thanks for sharing. Andy

People here who buy Bosch bikes, and ones driven by Bosch motors as well, call their bikes "Bosch!" The name on the motors is very obvious, obviously for marketing reasons.... That the components are made in the far east, and possibly assembled here, as someone recently posted, I myself cannot...

I read just about every post here, including all new topics, and the only way your comment might every become true for me personally, is if I have missed them. So if you would be so kind as to post any and all links to those topics you are mentioning, supporting your thoughts, with regard to...
