Re: KMC v Sram chains?

Although ebike based, this is quite interesting, especially as ebikes must be harder on chains than non ebikes;

Re: Axle conversion

I am not sure the OP is suggesting 9mm axles are unsafe. I think they are asking if the kits/methods used to convert a hub from one axle type to another are safe.

Re: Petition to increase the 25kmh limit on electric bikes in the UK.

You keep being dismissive of those you consider slower than you as if they didn't count, that's me, yet for the last two years No, I simply consider that getting people out of cars and into bikes is more important than folk who use bicycles as a hobby - hence the "retired folk" comment. I...

The Netherlands seem to have been wresting with this issue for a while.

Re: Petition to increase the 25kmh limit on electric bikes in the UK.

I don't think that there is any I who should or shouldn't be riding one. But that is not the same as saying that the speed limit should be removed. I agree. There are very few people for whom an ebike wouldn't increase the numbers of journeys a bike can be used for instead of a car. My bike can car...

I don't think that there is any I who should or shouldn't be riding one. But that is not the same as saying that the speed limit should be removed. You and me have completely different use cases for ebikes. When you're dodging rush hour traffic on dual carriageways and in town centres you might hav...

Re: Petition to increase the 25kmh limit on electric bikes in the UK.

Not long ago the common opinion on here was that allowing ebikes on cycle paths would do exactly the same. Did it? Have ebikes put people off?
If that wasn't true then why should the same assertion be true now


No. Why? Because they are restricted and mix well with other bikes.

Re: Petition to increase the 25kmh limit on electric bikes in the UK.

My ebike starts to cut out at 15.5 and fades out by 17 mph. You can feel it happening and it does not fall off a cliff. It also has a speedo so you can see what's going on. The percentage assist is the amount by which the motor matches your input. The nominal maximum sustained assistance is 250w. I ...

Re: Petition to increase the 25kmh limit on electric bikes in the UK.

No disagreement about that either, the only thing we differ on is where that limit is placed. The 15mph wasn't plucked out of thin air, it was considered the speed that would be comparable with most cyclists. I know you don't like this argument and cite your own experience to repudiate it, but were...

Re: Petition to increase the 25kmh limit on electric bikes in the UK.

But on the mixing.... would "using imagination" be considering a transport system very different from what we currently have? Many of us would like that but it would take a lot more than the change supported in this petition... And this is another of my "bugbears". We all want a...

Re: Petition to increase the 25kmh limit on electric bikes in the UK.

That line of the argument against is that there would be more people doing something undesirable and dangerous. Jonathan Can you quantify how dangerous? I suspect you can't. Lower speed isn't always safer - try cycling at 5mph on busy roads during rush hour. In fact one of my bug bears about roads ...

Re: Petition to increase the 25kmh limit on electric bikes in the UK.

But they still wouldn't mix well with ordinary bikes on cycle and mixed use paths. For that reason, for an ebike to be considered 'just a bike' I think it's good the restriction sits at 25kph. Who says they have to mix with normal bikes? I'd suggest that's merely a lack of imagination. Having said ...

Re: Petition to increase the 25kmh limit on electric bikes in the UK.

I get what you are saying. I don't have much experience of this but it seems as though in some places there are two Ebike standards because the infrastructure can cope with the faster bikes - fast bike routes and normal bike routes. But we don't have the same infrastructure and a speed increase tha...

Re: Why the sudden urge to ride bikes on gravel?

My daughter wanted a new bike. I was, of course, pleased about this so we discussed what bike to get. Thousands of link containing texts later and she had decided on a Canyon gravel bike. I looked at the picture and said too long and too low... Wrong bike. Anyway after a long wait, it arrived. It ha...

Re: Petition to increase the 25kmh limit on electric bikes in the UK.

I guess the whole sectarian divide between different groups of cyclists is part of the problem... In reality, ebikes offer the chance for a reduction in car use and that's why I ended up with my ebike. It eats into my car mileage the reduction in which had stubbornly plateaued. Ebikes as a viable m...
