Your dropouts don't look the same as the latest ones. I'm not a hundred percent sure but I don't think they're using chains at all now except on the derailleur bikes. It's all Gates belts now on the hub gears. Or perhaps they haven't changed all the bikes over yet. I posted this youtube vid on...

You'll be able to sell them on to anybody else who wants a chain tug I should think. You only really need one on the drive side anyway. The new dropouts are shown on page 8 and 9 of the Kalkhoff Highlights 2015 as well as Details of the Development Department...

When this problem surfaced I reasoned that the manufactures would not design a bike where the back wheel could not be made to stay in place. So the first thing I did was to clean everything up and make the contact surfaces as perfect as I could and refit it all according to spec. I sanded the...

Yes the illustration and the torque numbers in the Kalkhoff manual on the wheel fitting page is lifted from this Shimano data sheet. But as I found out just under the given max of 45 Nm was too much for the nuts..... Unless they had been over tightened before I bought the bike of course. It...

Just noticed this post. I don't think this problem is peculiar to Kalkhoffs. On another thread a few months ago some other people had the same problem with Bosch motored bikes. Can't remember the makes though. It's more a problem with the forward facing dropouts which are commonly fitted with...

i hope the shorter ones will fit okay. I did roughly measure where my longer one sat when fitted and I think they will. I got the longer one to be sure and that one is stainless. I'm not sure about the shorter one... These sites are useless when you need even basic information. When you can't...

Many people use these forums to complain about service from dealers and companies so we should also post when the dealers do things right. I had a problem with the battery on my Kalkhoff Agattu i8 HS which I bought from a member here in the summer. It was well within the warranty period and...

I tried the Pro Connect 9 Impulse 11 at Bristol the other day when I had to go there to pick up an exchange battery. I have an early 2013 built Impulse 1 with the mid 2013 Sport profile software upgrade, and that gives it more power than the first Impulse. But this was significantly more...

Maybe so but I took it from the Kalkhoff manual and I used my torque wrench too of course. That's how I could torque it to just below the recommended max. I think it's a problem which started with the Impulse motor since that's a lot more powerful than the Panasonic. It's also most common with...

The Kalkhoff rear wheel fixing is a problem. They seem to have finally realised that the forward sloping dropouts are not suitable for crank drives with all their extra power and have redesigned the dropouts on the latest bikes. I had the same problem with the wheel pulling forward under load...

If you're looking at Kalkhoffs the Pro Connect 9 has £200 off for a few more days and that's a 2015 model with the Impulse 11 motor. It's only a bit more than this one and is more powerful than the Impulse 1 in the i360; and the new ones have a motor interrupt function to ease gear changing too...

I use it for cleaning because where I live in the country with no gas supply it's the best stuff to use for central heating. It's actually 28 sec kerosene though, a less refined kind of paraffin. So for cleaning it's just the same as that. But a lot cheaper if you're filling a big tank.

Car manufacturers don't make all the parts that go into a car. Just like bikes they are a collection of parts from different places. Dampers, brakes, gearboxes, even engines are found across different makers. I don't just mean car groups like Skoda being reworked VWs either. The ubiquitous 1.4...

That goes to the point of the problem with warranties generally. They operate in the way the bicycle industry always did based on shops. No one has noticed that pedelecs are now much more like motor bikes than push bikes, and many of the shops don't know how to fix them. They only know how to...

That could well be true too and I expect it does have more of both. How much more is the question. I've got to go to 50 Cycles in Bristol this week to exchange my battery and I hope to ride one of the Impulse 11s then. So I'll see if it really does have nearly twice the grunt.

I was thinking of the standard CD which I think he said was 35Nm at 75 revs. The higher figure was for the new Krieger which is a higher powered CD motor I think, and that's 85Nm max 45Nm at 75 revs. Judging from my experience of the Woosh CD Sport I think the Kalkhoff Impulse 1 has more torque...

I just noticed that you had edited your post with some useful info. The max that Woosh quote would be the theoretical max at zero revs I assume? So if that is correct then the others are probably doing the same. Therefore the scepticism in my OP was justified and these figures really don't mean...

Yes. I've heard this idea of maximum torque being at zero revs before. But in practise it's really as meaningless as Schrodinger's cat. So what sort of torque and power is a Bosch or Kalkhoff outputting at the crossover point where torque has diminished and power risen?

Yes I amended my post to take account of that before you replied. The Mini is about 3000 revs for max torque, and that's about the revs you'd be using on a steep hill in first gear. So torque would be coming into play as much as maximum power which would be at almost twice those revs.

Thanks trex. So Bosch and Kalkhoff have more torque at the crank than a 1959 Mini? You could get four people up a steep hill in one of those in first gear. I wonder if I got three circus acrobats to balance on my bike if I could get us all up the same hill? The Mini had a lot of metal in it to...
