Regulations for fast, powered vehicles even if they are light weight are necessary to protect innocent bystanders and children.

Why aren't there regulations to protect bystanders from fast lightweight racing bicycles?

Seriously?  It took years of training, and countless hours of practice for me to be able to ride my 16 pound race bike at the speeds I am able to push myself.  You want to compare that to a 40 pound e-bike that any moron who can hardly ride can get up to 30 mph in an instant?

I assume you don't argue for having more regulations for fast lightweight racing bicycles and I don't either. So then you have the main reason: we can all agree that we don't need them.

Now, AFAIK we do have the same speed limitations for human powered bicycles as for any other means of transport, like cars or motorbikes. We just don't have constructive speed limitations on human powered devices and we also don't request a license to use them, which makes them unique. Why is this reasonable? Because most humans cannot produce more than 150W sustained power, constructive means would be technically too intricate for the small gain in safety and the sport of cycling is considered part of our culture we cherish.

And that is why HPVs are generally unlimited, because only the able can bring them up to dangerous speeds. This helps not against morons, but drivers licences and other regulations don't either, as anybody can get one, and few ever loose theirs.

 

How does this apply to the EUC? I see them sitting in between the chairs, because they are not really self propelled (like push the accelerator and it goes fast) neither are they humen powerd or power assisted. Well, you actually need to make an effort to counter the torque from the wheel with your feet.

Anyhow, I think regulations should be instated within reasonable measures. The big problem here is the inabillity of self balancing vehicles to have a fixed top speed, so the legislator would have to find a new way to regulate these vehicles, e.g. fixed tilt back settings. But who is going to explain it to our politicians?

Licensing riders is fine but they have to be considered bikes not some motorcycle or moped that requires registration and insurance. If it cant be ridden on bikepath and places bikes travel it's pointless. As soon as they are treated like motorbikes you may as well just ride your 1200CC road bike everywhere because buying a second ebike just means endless insurance and rego fees for a bike you rarely use. If an ebike doesn't require rego + insurance and is allowed on bike areas its a valuable option for short commutes instead of your motorbike or car.

They are not treated as motorbikes. In particular, they don't require a motorbike drivers license, which most people do not have and which is much(!) more complicated to acquire than registration and insurance.

I agree, also fast e-bikes should be allowed on bike areas. AFAIK this is the case for example in The Netherlands.

Even better that Musk's batteries ... the battery you don't need to charge and generates above 50% of their maximum power for as long as 5,730 years; glows in the dark so no need for disco lights; warms your legs on a cold day.  What's not to like?

And the next generation of battery tech -- lithium metal batteries double energy density.  This is being developed for Drones (to be released in 2017) and next autos.  Both are high discharge rate applications, which bodes well for EUCs

This is the big discussion right now on Wall Street, and the reason that Tesla's stock has done well while still burning through piles of $, while in contrast traditional auto firms struggle.   It's now received wisdom that electric self-driving, ride-sharing vehicles are the city transport of the future; we are 1/2 way there with increasingly common autopilots, sharing economy, $30/hr parking (for owners only), and better cheaper batteries.   Zip-car, iGo, etc., Uber-Lyft point-to-point, are doing well in Chicago and other cities, and even now, we personally debate whether we should keep our car, or rent when we need.  With full autonomous ride sharing, we'll be able to rent an autonomous car that will be at our doorstep when we beckon, and be gone when we don't need it.  Blind people, children, invalids, etc. will be able to get around in ways they could not in the past.   Why would you deal with parking, insurance, city stickers, etc. when you could get better services for a fraction of the cost and hassle.

The question is "where do PEV's fit into the mix?"   It has to be where "1 person = occupying 4.5m x 1.8m road space" is a constraint; in malls, parks, pedestrian walkways and shopping districts, and so forth.  We don't see as many of these as say in China or Europe, so the US with it's rural-suburban user base will be car based for a bit longer.  But hopefully in the future US cities will adopt more of these European and Chinese innovations (in design, but without the smog:o), and PEV's will be an important part of the solution.  In Kunming, Yunnan any motorbike inside the 2nd ring road (an area of ~5 million population) needs to be electric; other cities are adopting similar rules to control pollution. 

I believe there will be 2 main paths along which the PEV should be developed:

1. the last 1-2km PEV,  5 to 10min ride, for which speeds like max 15Km/h are more than good enough, max 14" and  max 7kg, and for which not a lot regulation is needed.

You could put one in the trunc of your electric car where it will always be charged. Prices will depend mainly on weight (saving) like with superflat and light laptops (magnesium frame, carbon outer shell, titanium pedals, AI recognition of owner, AI collision prevention, VR heads-up information, etc)

2. higher speed PEV powerhouses that will be a substitute for e-bikes or even motorbikes, and even electric cars, which should be highly regulated.
