How do the manufactures measure claimed torque? Is it at the crank or at the wheel? If it's at the wheel then it would be dependent on gearing so how would that work? Bosch claims 60 Nm I think while the Impulse 11 claims 70 Nm which is nearly double the 40 Nm for the first Impulse. I don't know...

I'm not sure the Groove motor is made in China though it might be. The Impulse certainly isn't. It's made in Germany by Daum who Derby Cycles bought a half share in to use it. The battery will be German made too as will the frame and wheels. All of which are of better quality than the cheaper...

No the Kalkhoffs are made in Germany. It's an introductory launch price according to 50 Cycles who posted here about them. Certainly is the cheapest Kalkhoff ever I should think.

Must just be German law then. I expect the last time I looked at the Highway Code was when I sat my test fifty years ago. I think the red flag law for motors was still current.

Interesting comparison on the blog. All the stats seemed to show that the Yamaha is a similar or better motor but the subjective view was that the Bosch shaded it. Mainly on the finish of the display and a preference for the crank fittings and a few other very minor issues. Seemed to me that...

Lamp oil used to be available at one time which was more refined than paraffin. I have used paraffin in lamps and it's a little bit smokey compared to that. 28 sec kerosene is what's used for heating oil in this country and is less refined again than paraffin. If you put that in a lamp it smokes...

That might be one for the OP to think about. Must be a market for these things at a fair price.

That Flyer certainly is. You would have thought one of the cargo bikes was long enough to be adapted to be one. For that price I'd want a rickshaw wallah thrown in. Preferably female with powerful gluteus maximus.

Not really relevant to this but looking at the manual for my German bike the other day it states that bikes over 11 kilos must have independent lighting from a dynamo, and not internal battery powered lights. Presumably an e bike battery powered light would be okay too. I wonder if this is just...

Looking at all these cargo bikes with seats I can't help thinking that if you're going to carry a passenger then they might as well be pedalling too. With a motor to help a tandem would be easy to ride alone I should think. I wonder why no one retails an e tandem?

Water will work fine as brake fluid it just rusts none stainless components. Plenty of MB bikers still use it. I remember many decades ago having an old Ford Zephyr that was buggered and taking up space in my garage. Among other things it has zero brakes. So we put some water in it, pumped up...

The lazy man's brake bleeding method.... I used to do that with cars a lot. Rather than the hassle of bleeding just pump them up and wedge a piece of wood down on the pedal and up to the steering wheel. Left overnight and the brakes are free of air. Pressing down too hard will bugger up the...

Woosh have some demonstrators around the country who will let you ride their bikes if you look on the site. There may be one near you. Your usual route may be flattish, but if you have the extra power and range then you can go anywhere without any fears of not making it. You probably will start...

I really doubt either would be very nice to ride unpowered. I had a lighter Woosh CD Sport and that was not pleasant unpowered. My Kalkhoff Agattu isn't all that nice unpowered except when it gets up and rolling on the flat - of which there is very little where I live - either because it like...

They recommend it to set and later reset the battery's management system parameters. He must have been riding on flattish ground because when I rode my 17ah one to system shutdown it took 47 miles of very hilly terrain at max assist. The last few miles at very low voltage is almost zero assist...

CTC do a third party insurance which can be used anywhere in the world except the USA. I don't know if you have to be a member first. http://www.ctc.org.uk/insurance/third-party-insurance

I was reading about this on the other thread. Do the Spanish want insurance for all e bikes or just the ones with throttles? The certificate of conformity can be copied from sites selling the bikes or manuals usually. But do you still need insurance there even with it? Then the Spanish English...

I always liked the Ice Cold In Alex ad. But in the film the glass was labeled Carlsberg which made it easy for them. Product placement, like most things isn't new. Haven't seen this Sainsbury one but there has been some comment about it. All advertising is derivative and exploitative. It's just...

How are you finding the power interruption feature? I've got a Agattu i8 HS with the Nexus gears and I don't have any problems changing gears smoothly. But it reminds me of changing gear on a truck. It's so slow and deliberate. I'm thinking of buying the Pro Connect 9 if the change works...

I think you're having problems with wording. Being defensive and being assertive are not mutually exclusive. Although perhaps decisive is a better word than assertive. " He was right of course, right all along. But he was just as dead as if he was wrong."
