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.

Personally I feel that for around 15mph with assist, being able to use the bike paths and with no regulation, insurance, training - is fair.  It's a bit "how long is a piece of string" and I understand the UK need to "keep up with the cars".  However (I hope) we're in transition away from the old UK model of the fit and the brave.  At that point we're talking "cycle infra".  And the speed of the average person on a bike is relevant.  Which will be lower than that of today's roadie.

For a faster commute I'd have thought a speed pedelec would have you covered?  Unfortunately while currently possible in the UK - and up to 30mph - it's less convenient than it might be.  We have "bike / ebike" or "moped".  So as road.cc wrote you need to jump through several hoops.

However... while it might make sense for the law to take notice that speed pedelecs are mechanically closer to bikes than mopeds the key thing here is "goes at 30mph".  If we think people need certain restrictions for a moped then we should be thinking carefully whether we should skip or relax them when applied to a speed pedelec.

I'd deffo be cautious of using the promise of "moar speed" to try to tempt people onto bikes (unless it's "less haste, more consistent average speed" e.g. proper infra!).  Look how that went with cars...  Plus people can get a moped right now - yet they aren't the major vehicle on the roads, so I'm not sure that works as a temptation.

At the point where you're considering a speed pedelec in the UK, you'd be better off just getting a moped with all the regulations that involves - including having to wear a motorbike helmet. I did briefly consider it before dimissing the idea.

I get your point about lack of training etc. but there's nothing stopping someone buying a road bike with no training and riding flat out on a shared use path. I don't think a slight uplift to 20mph would be problematic.

Well... someone with no training and they can keep 20mph up regularly?  Some talent spotted there!

Just because some can with effort doesn't mean most will under normal circumstances.  The whole point about motorised things is the reduction of effort (to approx zero, if it's a car or a motorbike).  So it's fairly likely people who are not well equipped to handle 20mph on a bike (on roads or cycle infra) will be doing somewhere near that, a lot of the time (depending on level of motor assistance obvs).

*Preaching* That's one of the joys of cycling - in safe conditions.  A child can do it.  It isn't like driving a car, where a lot of training is required and alertness should not be optional.  It shouldn't be like cycling on a busy UK road where concentration is a requirement for self-preservation.

I know the numbers are arbitrary.  With more speed for a large number of people come some problems.  Some of which increase more than linearly with increased speed!

Well maybe there's an argument for another category of e-bike, 20mph, no licence, registration, helmet or insurance requirement, but banned from shared paths and some cycle lanes. It's not like the bikes don't exist, it's what the majority of e-bikes sold in the USA are limited to.

If you live in a city blessed with infrastructure and where 15.5mph is enough, you get one of those. If you've got a longer commute on rural roads and A-roads with next to no cycling infrastructure, you get a 20mph bike.

That's a fair shout I think; this is where geofencing could really come into its own.

I think that fails the "is this enforcible practically" test, and therefore passes the "this law is an ass" criterion, I'm afraid.

To be fair, it's not like there's much enforcement of the illegal e-bikes that can go way faster than 20mph anyway.

If it was GPS ringfenced, like rendel says, similar to the way drones won't fly in certain areas, then it could work. It might even mean that less people are tempted to ride illegally modified bikes.

There was an illegal e-scooter in Garstang yesterday, about 100 yards from the police station

Sounds like a great idea. I wouldn't want to do 15mph on most cycle lanes I've used but I'd happily stick to the road and go at 20mph.

As an e bike user I'm happy with the current limit, I am not a lifelong cyclist and took up cycling for gentle exercise after retirement but even I can average over 15mph on the flat.

I just need some help on gradients approaching double figures.   Increasing the limit would take a lot of the enjoyment out for me.

The legal limit is not going to be increased- one of the very good reasons is that the legislation fixes the limit about right. Reasonably fit cyclists on reasonable bikes not overburdened with luggage will overtake most e-bikes on the flat (maybe that doesn't apply to stealth e-bikes) and will lose out to ultra-unfit e-bikers using maximum assistance (which they all are) on hills. My experience is that you catch them on the downhills, but if it's hill after hill they'll get away

Watched 5 minutes, good presenter but got bored at that point.  Very pleased that someone's chose to cycle and that an electric bike helps.  They've noted some good points like "faster up to speed at traffic lights" etc.

So up to where I got to the main issue seems to be "Bloody cyclists!  Overtaking me on their non-powered bikes!".  To which the answer is well, if you can't go faster on a powered bike then - like the others -  go faster on a non-powered bike.  But put more effort in and maybe get sweaty.  That's the trade-off.

I'm guessing she's sometimes thinking "should I have gone for a motor scooter after all?"

The other issues were "but I'm in the way of cyclists" - not really a drama.  It's partly a consequence of the UK road cycling environmental selection for "the quick and the brave".   Would be fixed by "more bigger cycle infra".  Next: "but I have to keep up with cars".  Simples - reduce the speed of the cars or "more cycle infra".  Finally "but it's bigger / faster in America" - maybe, but also mostly (much) worse outside of a car.

At least in urban areas the average speed for everyone will likely be much lower than a legal e-bike is capable of.  Including in cars in many places.  The way to address that is not by increasing the speed between long waits at traffic lights.  It's the "tortoise beats hare" method of just not stopping as much or for as long.  It's allowing cyclists to avoid the lights entirely (one way or another), or better phasing of lights to suit buses and people cycling and walking, not "general motor traffic".

She needs to decide when she is going to compare e-bikes to cars and when she is going to compare to "accoustic" bikes. For example her e-bike can be used on shared paths and cycle lanes, which is her argument for wanting to go faster, then decides to compare their safety to cars which (legally) can't use them. 

My opinion is most people who would ride an normal bike "leisurely" would be doing 15mph or so maximum anyway on a flat, she can go faster uphill then most normal bikes, so her journey times wouldn't normally be different. However if she could then be assisted up to 20mph everywhere, wouldn't normal bikes be holding her up in the same circumstances. Actually it would be a hell of a differential speed depending on steepness. 

Also, if they can't get her bike going anymore then 16mph on the flat by pedalling unassisted normally, then keep it at a speed they can handle or get an normal bike and go faster, but put up with change of clothes and being out of breath sometimes. (Her examples of faster bikes, was she doing the "limit" but also looked like they were pedaling hard to get those speeds).
