Interesting to learn that age in years is sometimes more important than topping up the charging. I note that the glowing reviews on good batteries that last a long time are offset by the relative price, so there appears to be a levelling out of cheaper batteries that last two or three years...

I notice many trade ads on Ebay and elsewhere which offer limited one year warranties (as this one does) on a small proportion of the bike's parts. Surely consumers know by now that they already have a statutory warranty (Sale of Goods Act) for ALL parts of ANY item sold new for at least a year...

Hi Biker44, I think in my case I was sloppy about keeping the first battery conditioned. In the first year I rode the bike very regularly. Due to the bad weather and winters of the last two years I must admit I didn't ride anything like so much but also failed to occasionally charge the...

I'm pleased to say problem solved at last. I went to e-bikes direct in deepest Kent-Sussex borders, but they don't sell spare batteries! (one of the biggest e-bike suppliers in the UK). But they did have a couple of very helpful people there and kindly filched a battery from a bike they had in...

Thanks for that US link d8veh. I see the connector pins and block are indeed included, so I assume with this kind of battery I unscrew the bike's controller top panel, disconnect the pins then replace them with the pins included with the new battery, taking care to put them the right way round...

Sorry I didn't mention this, but I saw several posts on various websites saying variously that reverse polarity either ruined the controller or resulted in the hub motor going backwards. But there is more to it: Because the polarity was reversed the "fit" of the pins into the battery was also...

I have an ebay-purchased folder. The bike itself is brilliant for the modest price and is now three years old. I ordered a new battery from an Amazon supplier and went painstakingly through the specs with the seller before committing. However when the battery (36v 10ah) arrived the polarity...

Just seen this thread so rather a late contribution. In my area there are a lot of coastal paths and sea-side promenades shared by bikes, e-bikes, pedestrians, mothers with toddlers, etc etc. Even 15 mph in these situations can be too fast. On the other hand if you were on an empty-ish B road 15...

Thanks so much d8veh. Battery ordered £199 and arriving tomorrow. Excellent and quick advice which I really appreciate!

I've always found d8veh's posts extremely helpful and knowledgable. Seems to know his onions and always gives straightforward answers. So I'm adding my thanks to him too!

Hi Flecc, Yes I agree, in China an e-bike is a utility machine that is essential transport. The Dutch approach to e-biking also makes sense when you consider that for decades the average Dutch family sees bikes first as a just an A to B transport and not primarily as an object solely for...

Hi Flecc, Good to have your contribution. I don't know exactly how reliable these figures are: But according to various sources, total e-bikes sold last year in Europe as a whole = 380,000. Sounds quite good until you compare that to plain bicycles. Contrast China where e-bikes are an obvious...

Thanks for that Dave. Well maybe my Claud Butler example is a one-off, but that was not the only story I heard. As a general point, I was talking about snobbery, a subject that I see has come up on this forum quite a lot. The greatest snobbery I see in fact comes from retailers who just are not...

Hi Martin, I do concede that the bike in question was a specialist machine and yes I agree my folder would not survive an afternoon in the Alps! Sorry if I picked on you. Perhaps I was aiming at other, less exotic machines that really are little different from my modest folder but go for...

Allow me to make something perfectly clear. I compared the CAPITAL cost (not running cost) of a second hand Ford Focus not to argue that a polluting, road clogging, non-contributor to fitness is superior in concept. I merely pointed out that even despite economies of scale in the motor industry...

Two and a half grand for an e-bike? And apparently four and a half grand for some of the more "exotic" models. Good luck. I know someone who recently bought a ford focus estate with less than 40k on the clock, a years warranty, and all in fantastic condition. It has a largish engine, four...

That rider, assuming he is not now dead or worse still maiming or killing others, is the very reason why we have a 21 kph restriction. It's idiots like him who have brought about a regulation that to some seems inflexible and somewhat restrictive. It's not a matter of if, but when, this muppet...

The charger says the output is 42 Volts. How do I know whether that means the bike is 36v or 24v?

Thanks for that quick and knowledgable reply d8veh! Odd thing is that original seller describes battery as 36v but many websites with exactly similar batteries for sale including measurements, key position, charger etc describe them as 24v. Presumably the corollary is also the case: that if I...

Thanks for the answers. I have another quandry: I think I might have forgotten whether the original is 24 volts or 36 volts. If it is 36 and the motor or controller is set for 24v will it burn anything out? Is there a way I can use a meter to test what the voltage output is even with the battery...
