20 mph speed assistance limit for E-bikes?

Interesting little 10 minute vid arguing for the assistance cutout speed to be raised.

Very well presented on a bike ride around London.

For me it does not convince, since the case is based around wanting faster journeys when the main delayer is stop-start not speed, to 'avoid blocking cycle lanes' for faster people on normal bikes are actually routinely slower at about 10mph average, and so on.

It's a fair question. Visual deterrence (especially for teenage would-be shop lifters that don't realise the security guards can't do anything), can be useful for first aid. A lot of stores have known problem people that security guards follow around/ask to leave.

Well trained security guards can draft a good note as evidence for the police (it's amazing how many people present assumptions as fact, which then can be ripped apart in court)

Of course the very best use for a security guard is for hiding security tags in their uniform so they keep setting the alarms off.

Erm... So what are they being paid for, exactly?

As a deterrence and to occasionally eject unwanted customers. I've seen some cardboard cutouts of police used in lieu of security guards at some bargain/pound shops.

Oh - so that's private enterprise?  I assumed that what with cuts, Brexit Covid Russian war that was all we could afford to bolster police numbers.

Now you mention it though, maybe having some dummy cars / appropriately posed cardboard road police at prominent locations might help?  After all if just a pair of eyes will change behaviour...

Thought they were present at various fuel stations.

This started with cardboard cutouts of police cars back when they did speed checks from motorway bridges. The first ones I remembers were Rover 827 Liftbacks (ie Rondas). 

They used to get stolen.

The Waily Mail reports a stooshie in Edinburgh about a cardboard policemen holding a speed cameras in 2018.

yes It's not something I've experienced elsewhere, I admit, and it certainly doesn't pertain in any of the other supermarkets around here where I either walk or I cycle with my wife and one of us stands outside to watch the bikes while the other one goes in!

Genuinely tricky one.

Technically it would be based on disfunction, so presumably if you have a leg off for diabetic reasons you qualify.

Fortunately, the increase in the assistance speed is not going to happen. Those who are desperate to go faster can just illegally modify the e-bike- they'll never be apprehended, just as the police ignore those illegal e-scooters

The key for me is to discourage cars from overtaking cycles in urban areas. This could be by enforcing a 20mph speed limit with a MUST not overtake cycles in 20mph pedestrian and cycle zones, like I believe exists in other Countries in Europe. We all know it's largely pointless to overtake someone making progress on a cycle anyway!

If assisted bikes had a 20mph limit then it would be fairly obvious when the law was being broken in these zones.

I live on the outskirts of Birmingham and on the very rare occasion I've had to ride across it, I have felt like the safest option is try to go at traffic speed to avoid dangerous overtakes. 10 miles of CX like effort at either end of a ride isn't nice!

If the UK already had a blanket urban 20mph limit that was strictly enforced then I think this would be a great idea.

The limit was not a carefully researched figure based on safety, we simply copied the existing Japanese 15.5mph limit instead of the American 20mph limit.

My ebike stops assisting me at 15-ish mph (for my safety?) but I can coast (dangerously?) down a local hill on my unassisted bike from a push off and reach 25mph+ without pedalling so I'm not sure what the difference is.

70%-ish of trips are less than 5 miles. If we want to get people who would automatically choose a car for these journeys onto bikes then slowing down vehicles and speeding up e-bikes makes the private car virtually pointless for many trips.

We could also make the left lane of all urban dual carriageways a bus/cycle lane which might even demote private cars to third choice for most people making short trips in urban areas.

Making the default 20mph in urban areas would be good!

I don't know where the 15.5mph / 25kmph thing originates but - whisper it - the same rules apply "on the continent".  If you Google there appear to be EU directives about this.  They probably stole it from the UK though.

Travel choices are not just about speed.  For most it's overall "convenience".  Yes, for some people, for some journeys more speed is better.  (Hence illegal electric motorcycles).  As for bike vs car if we're going for mass cycling that means more infra to make cycling more convenient than driving for some trips.  Here's the synergy: even in existing UK cities cyclists can sometimes get there ahead of other transport options (if that's the most important thing).  They can manage a higher average speed.  Now with more good infra that becomes more widely possible - because bikes don't need traffic lights where there aren't motor vehicles!  That's part of how the Dutch [1] [2] and to some extent Danish get ahead.

Secondly even though some current cyclists say they'd feel safer in among motor traffic if they were going faster most people in the UK just don't want to be in motor traffic outside of a car.  Note that you can already buy a motorbike or a scooter and "speed like the cars" in places.  This is not a very popular option.

Upping the speed limit for ebikes and also having relaxed rules for e-pedelecs seems to be the industry seeing a new potential market to me.  Doesn't make it wrong - but we should certainly not rush into it.

Bus lanes - maybe we should have more dedicated bus lanes.  Just like cycle infra though how junctions are dealt with are critical.  Otherwise you've just got more buses blocked by cars.

As for bus / cycle lane - although I appreciate in the "survival environment" of UK urban roads many appreciate bus lanes this isn't a good idea long term.  Buses and cycles don't mix well for several reasons [1] [2].  Our current ones often only exist for part of the day and can be busy with taxis also.

I'd say "more convenient by bike" needs to be the established norm, and am explicit goal - but we are not there yet.

Straws in the wind for a real culture change for me will be when we have:

1 - Routine use of detection loops (or several detection loops) to turn the traffic off when a person on a bike needs to cross so they don't have to stop.

2 - Pavement level crossings across side roads and for Toucan etc crossings as default.

3 - A sensible rule around "either the speed limit is 20mph, or it has a dedicated cycle track."

4 - And I think a rolling review of all our streets and roads, especially junctions, timetabled over 2 decades or so.

I like all those!  We know it can be done, because others have done it.  And not just cities / countries who started from a much better place than the UK is now.

I'd say 20 years is extremely ambitious!  We could save time though.  We can see the nuts and bolts of "what works".  The UK even already has some "knowledge" of proper infra here.  We certainly know "what doesn't work" here.  We could combine knowledge of our failures and eliminate things that are the same in the UK as where "it works" to help us spot the elephants in the room - the things we just can't seem to see.

However I think most people do know that really.  It's just the vicious circle of "can't move motor traffic from the number 1 spot".  Plus our divvying up of public space for people can store their private property (cars) for free etc.  And "not invented here" is very prevalent in the UK.

When I said "we" I meant the EU as this was pre Brexit. 

As for cycle infra, I'm guessing it will take many years to improve even a little and we'll probably never get it on every urban street so people will still prefer their cars over bikes. The law could be changed tomorrow to match e-bikes and cars top speed limits at 20mph and instantly bikes would make more sense than cars for many more people. It wouldn't cost much more than the price of changing all the speed limit signs too.

On bus lanes I can only speak from my own experience. I've spent over 20 years travelling the same dual carriageway and for about half that time it had a bus lane almost the entire length with priority traffic lights at some junctions. That is now gone and it is just a plain dual carriageway. I can honestly say it went from a safe quick ride past queues of traffic every day riding in the middle of my own almost empty lane to a nightmare of threading through two lanes of gridlocked traffic or multiple dangerous 40mph+ close passes every trip. I know which I prefer.

Of course we could just get drivers to be safer and more conside . . . . . . no sorry, I'm just being stupid now.

In UK law, a two wheeled vehicle that has pedals and provides motorised assistance between 25 and 45km/h is classed as a moped, which have to be taxed and registered, and can only be ridden by those aged 16+, wearing a compulsory motorbike style helmet and holding a valid  licence having undergone some training. 

Restricting eBikes to 25km/h means they are classed as bicycles and can be ridden by anyone. 

At some point those moped rules probably need to be revisited as they are getting a bit long in the tooth now (when was the last time you saw an actual moped?) but that is what we are stuck with for now.

I saw a moped in Altrincham this morning, actually  commented to my wife that the guy would be putting his ride on Strava.   (Because I've spotted a few 30mph+ segments recently).

I think the 15.5mph limit probably comes from the Dutch 'snorfiets', a moped with a maximum speed of 25kph that is permitted to use cycling infrastructure and where no helmet is required to ride (although this is changing).

As much as the Dutch don't like mopeds on the cycle lanes, I do think having to cater for moped traffic has resulted in a better standard of infrastructure.

I've never understood the distinction for urban areas.  Why is the national speed limit on unlit, narrow roads with no cycle lanes or pavements twice that of roads which are well lit, generally quite wide, always with pavements and sometimes with dedicated cycle infrastructure? Why should country roads be any less safe than urban roads?

I don't know but suspect it's about compromises.  Urban environments are more congested in terms of vehicles, vulnerable road users, number of interactions, often the space involved (and other "obstacles" diverting / obscuring each) and overall time spent there (vehicles simply can't move as fast there due to traffic lights / other vehicles).  Countryside distances may be greater - increasing temptation.  Lots more countryside to police...

So there's recognition that simply sticking up a sign isn't going to be terribly effective.

I would support this, and it should be easy: if there's no centre line, default the speed limit to 30 mph. It won't stop the hooligans but might influence others.

There are roads in the Highlands and Islands (you know, the places that you can't get online delivery to) where there are some empty single track roads with very long sight lines and 30 (+ the speed drivers add as a garnish to any limit) would seem quite slow. So not a perfect idea, I admit.

I'd use the "non classified roads inside the community boundary default to 20mph speed limit" definition were I dictator, plus classified roads where there is no cycling infra. That would also cover small communities I think.

My comment on the vid:

To me arguments in the video do not convince:

1 - The statement about "Ebikes must be faster to avoid obstructing faster pushbikes" fails because -

a - there are very few such bikers - urban cyclists move at 10-14 kph. Even in flat NL with beautiful cycle tracks and higher fitness levels it is barely faster.

b - The obstruction is not mainly because of the speed, but because the cycling infra is too narrow - on the path filmed it is significantly narrower than the minimum standard under LTN 1/20.

As ever in the UK it is about developing a quality infrastructure, rather than trying to help cyclists behave like cars.

2 - If journey time are too slow, the need is not to be able to rush away from traffic lights, but to design the cycling networks such that people on bikes do not have to stop and have priority at traffic lights. That is what is done elsewhere; it can be done here.

3 - I don't think higher assist speeds for e-bikes help safety, especially for the elderly. The age profile of casualties in Belgium and the Netherlands (where single vehicle accidents for elderly people on e-bikes are a high proportion) would support that imo.

Personally, I would like to see the power and speed limit for e-bikes increased to 500W / 20mph.

In a city, it means you *shouldn't* have to deal with close passes in 20mph limits.

For my previous, mostly rural commute, it would have meant a shorter journey time. But crucially, it would have made the decision to get an e-bike a no-brainer.

Although I often thought about it, I never bothered getting an e-bike. I got quite fit on the road bike and during the summer, could average 17-18mph - hitting 40mph comfortably on the downhill sections. So I was unsure of the benefit I would get from an e-bike. It might have made the commute less effort, but could have actually taken longer, as it might have slowed me down on the flat sections.

The other day I was comfortably keeping up with someone on one of those silly Super 73 style bikes - uphill on my 20kg dutch bike with hub gears (and I am not fit these days, it was struggling to do 12mph)!
