June 18, 201510 yr Completed an 81 mile ride 5500 ft of climbing. Mostly on Eco/sport ( low and mid) but used full power mode as well for some hills towards the end. Battery was showing 3 bars on the dashboard indicator and one led on the battery itself so still maybe 5-10 miles left. I'm very impressed!

June 18, 201510 yr Which model of Kalkhoff bike was this on Lowranger? I'm interested if it is a standard or an "s pedelec" since I think the extra power and speed available on the S Pedelec models would reduce this range. Chris Ahh - just spotted on another of your posts that it is a Pro Connect Impulse 10 - as I thought the 250 Watt 15mph version.

This current crop of Kalkhoff's have been superb for range. I like the gearing on the Pro Connect 10 too, nice spread, you can get some speed up on the downhill stretches.

"This Kalkhoff's battery lasts a long time."
June 19, 201510 yr Was that really necessary ? If bad grammar and spelling was always corrected on this forum there would be no time to post about anything else !
June 19, 201510 yr The plural of Kalkhoff is Kalkhoffs. An apostrophe denotes possession. "This Kalkhoff's battery lasts a long time." Do you feel superior now Rob? Has this lesson in grammar filled a void in your life and made you feel slightly less inadequate?
June 19, 201510 yr Be Do you feel superior now Rob? Has this lesson in grammar filled a void in your life and made you feel slightly less inadequate? No. The poster is a director of the sole importer of Kalkhoff ebikes. Anyone who receives a written communication from him in business will not be impressed by a fairly basic - albeit increasingly common - error. You may or may not agree with that in your 'happy clappy we are all here for each other world', but people do make those judgments. Just as I do about posters who make stupid, snide remarks about 'filling a void in my life' and 'inadequacy'.
June 19, 201510 yr Author Hey come on guys. None of this is necessary. I posted the comment to be of use to members as a real world example of the the range of the bike not to start a criticism their grammer. Let's stick to ebikes and leave the grammer for the English language forums.
June 19, 201510 yr I can't make my mind up now. Should it be Kalkhoffs'? Because it's the range of more than one Kalkhoff bike which is being discussed. Either way, 80 miles, which was the original point is a long way. I hate this sort of thing on Internet forums, they always end up going off at a tangent and the original meaning is lost.
June 19, 201510 yr Author Very impressive but I guess you're pretty fit. Most of us, I fear, wouldn't achieve anything like that kind of mileage. Tom Hi Tom. I may stand corrected but I think that because of how the crank drive delivers the power then fitness would not affect the range as much as you might think. The less fit would use a lower gear (and go slower) but the assistance would be similar to a that given in a higher gear. What would be the bigger issue, I guess, would be the physical time that would then need to be spent on the saddle and gripping the bars. So even you were to halve this range that would still be a good ride for someone less fit and give them confidence they can aspire to longer rides when their fitness improves.

June 19, 201510 yr Personally, I find wrongly used apostrophes very annoying. I don't know what it is about them. I don't care about other grammatical errors. I'll happily decode a post with no senrences, full stops, capital letters or commas, but the moment I see that bad apastrophe, I switch off. Why is that? What is it that the bad apostrophes say about the writer that other mistakes don't? I fully support Rob. Bad apostrophes must go. Anybody that condones them should be temporarily banned as a punishment, and anybody that incites others to use them should be permanently banned.

I suppose I'm bound to like this post, but mostly because it made me smile. Hang 'em and flog 'em - love it. The most crass and annoying apostrophe error to me is using one to denote a plural. If in any doubt about apostrophe use, leave it out - you will not go far wrong.
June 19, 201510 yr Author English language lesson over. Thanks for the advice. Can we now just stick to the subject of the thread please.
June 19, 201510 yr The plural of Kalkhoff is Kalkhoffs. An apostrophe denotes possession. "This Kalkhoff's battery lasts a long time." Yes, I know that, a mistake after a long day at the keyboard. I have GCSEs and everything, but thank's for your help!
June 19, 201510 yr No. The poster is a director of the sole importer of Kalkhoff ebikes. Anyone who receives a written communication from him in business will not be impressed by a fairly basic - albeit increasingly common - error. The poster also has an upper second class degree from Oxford University but, like all other human beings, makes the odd grammar mistake now and then, despite being an insufferable stickler for correct grammar himself. I share your view about how important this is, RobF. I'm mortified. If you could go over all my previous posts on here, all the copy on the 50cycles.com website and all my blog posts, making a list of all the grammar mistakes as you go, I would be genuinely grateful.

(Post not check for grammatical errors) I don't know how many times we've been through this. There's very little in a bike that gives a user something for nothing. There's two main ways you can go a long way on an ebike. You can either get a big battery, or you can use the power from the battery at a lower rate. If you use the power at a lower rate, you have to either go slower or pedal harder. There's no ebike with ingredient "X" that can change that. There's no significant difference in the various ebike motor efficiencies, neither in the type of drive system. Some Kakhoffs have 17Ah batteries, so, for a similar effort, it will go approximately 70% further than say a Tonaro with a 10Ah battery. When people get a long range from their bike, it tells you more about the rider and their rides than it does about the bike. If you want a bike that can go a long way, get one with a big battery, not one that anyone claims to be more efficient. Real efficiency comes from reduced rolling resistance and wind resistance. Weight makes a difference too if you have lots of hills.
June 19, 201510 yr I have a Pro Connect 10 too, and I achieve about 100 miles with a full battery, using Eco mode (lowest mode) on pretty flat paths most of the time, with the very occasional boosts of assistance when climbing hills. In term of range, hard to beat, but some effort is indeed required, being a crank driven assistance (unlike the electric hub-driven "moped" with throttle). It's indeed the 250w impulse 2 version, with the 17ah battery. Assistance cuts off at around 17mph. I have very happy with the bike, but I think the cheaper Pro Connect 9 is probably as capable, but has a much smaller battery for the UK market. A possible issue with the Pro Connect 10 is that, being 10 gears, the chain would be narrower, and therefore more likely to break, given the high torque and strain from the Impulse 2 mid-motor. However, 9 gears are probably sufficient for most people, and could be more robust. Edited June 19, 201510 yr by Tomtomato
June 19, 201510 yr I don't know how many times we've been through this. There's very little in a bike that gives a user something for nothing. There's two main ways you can go a long way on an ebike. You can either get a big battery, or you can use the power from the battery at a lower rate. Isn't there a third way? Efficiency. If a motor is running at its optimum efficiency, which it is more likely to be doing if driving the wheel through a set of gears, then the energy stored in the battery will be used more efficiently, hence greater range. A hub motor, of which most are stuck in one gear, can be horribly inefficient at certain speeds. It more or less becomes an electric fire when stalled.
June 19, 201510 yr Efficiency is an area Kalkhoff's engineers are taking very seriously. At a recent meeting they told us that they're going for 'automotive levels' of quality and efficiency now. This is manifesting itself in much quieter motors in the latest Impulse generations, which is a good sign of efficiency through the entire propulsion system. I remember some of the old planetary-geared hub motor bikes I used to ride (especially front hubs) would 'sing', sometimes very discordantly and with a fair bit of vibration through the handlebars, as the power output increased. Once up to top speed that noise had mostly gone, but in the middle there was clearly a lot of energy being audibly wasted. Direct drives, on the other hand, are almost always silent.
June 19, 201510 yr A hub motor, of which most are stuck in one gear, can be horribly inefficient at certain speeds. Although I rarely find any argument with your posts Tillson, I find that statement a little contentious. I have to think you are referring to front hub motors as rear motors and the pedaller do have the benefit of gears.....unless I'm missing something. I have always been a big fan of crank-drive bikes although I'm spending most of my time on a rear DD bike at the moment. So far, I have never owned an EAPC with a motor I could hear while riding but I have had the displeasure of test-riding a couple of bikes with geared motors and I was seriously put off by the experience. Tim's anecdote of his experience of a geared motor very much reflects my own and while I have nothing against geared motors per se, I have been happy with my experience of both DD and crank-driven bikes. I mustn't discount the little Cytronex front hub motor either, which does a sterling job, again noiselessly. My partner, who weighs about the same as a box of tissues, can make her, (my) Cannonade fly when she hits the power button on that. Tom
June 19, 201510 yr The plural of Kalkhoff is Kalkhoffs. An apostrophe denotes possession. "This Kalkhoff's battery lasts a long time." It's a German brand- Kalkhoffer? Kalkhoffen? Anyway, I'm loving my Endeavour Alfine S11. 1300 miles on it so far, mostly commuting. Pretty certain I wouldn't get 80 miles on it though. Longest ride I've done is exactly 50 miles with about 2,000 feet of climbing. Total time out (including stops) 2 hours 48 minutes. Economy mode for downhills and flattish sections, cranking up the power for the hills. At the end of the ride I had one bar on the range indicator left. The computer was saying I had 3 miles left in economy mode, all higher power ranges were reading zero. The difference between my results and lowranger's are no doubt due to 1. My bike being an S pedelec so I'm trasvelling faster so more wind resistance for the battery to overcome. 2. I'm at least 20 kg overweight.
