Are the 28mph ones street legal without a driving licence?

They are limited to 15mph on UK roads.


Ah - I thought so.
When I was commuting, I would always pass them on my ride to work as my top speed on the flat was 34mph (with a tail wind).

The UK top legal power limit for a road E Bike is 250 watt, whereas

mine is 500watt. Hence the extra speed on mine. Very fast accelleration.

How many km have you put on it?

We wanna to hear from an E-Bike user who rode 250,000 km.

I recently acquired a 500 W Go Swiss Drive E bike with 37 N-m torque. 37 N-m comes out to be ~ a half ton of shear force on the itsy bitsy 1 cm long torque arm which acts as a shear pin, intentionally or not.

It's a stupid design.

Instead of a shear pin they need to deliver the torque through magnets on the torque arm and frame for a "torque circuit breaker" to preserve the drive shaft as well as the torque arm when something goes wrong.

Then all you need to do is reset the magnets like resetting a circuit breaker.

Also, the wires need to be designed to pop out of the plug very easily when something goes wrong to not damage the circuit board in the hub motor.

Then all you need to do is replug the wires.

As one EU automotive engineer said, E-Bikes aren't there yet.

But they soon will be.

In the meantime, I'll be peddling!

Do you enjoy your E bike for a bit of fun or is it basically an ornament?

I'm getting on now so I gave away my push bikes and just enjoy the
luxury of lazy cycling.
I fitted a trailer to it, handy when I go fishing.
I mainly use my car these days anyway.

I always think about the amazing life the person saying it must be
having. Hmmm.

Wouldn't it be easier just to tell the recipient to f*** off?

New research has found e-scooters would beat cars on most

There follows a serious question which you (and the
"researchers") might not be able to answer.

What is a "gridlocked UK city"?

Please be as precise as possible in your answer. Try not to
be evasive.

https://www.standard.co.uk/news/tran...-a4231841.html












Something else on the roads for grumpy old men to whinge about.

As far as one can reasonably tell, the vehicles whose praises
you sing are used almost exclusively *by* (grumpy?) old men
and women.

At least, that is so in the UK, whether or not in "gridlocked
cities" (whatever they may be).

In certain overseas territories (well, one in particular),
they seem to be used by anyone whose fancy it takes.

But please... don't forget to tell us what a gridlocked city
actually is.


walking will beat cars if there is actual gridlock, as would a
pogo stick, or stilts.
*
* Good job that scooters can go on pavements as well.

* Also, when the roads are gridlocked in London, the bike lanes
would not be.

Still no definition of either "gridlocked" or "gridlocked UK
cities", then?

* GRIDLOCK | meaning in the Cambridge English Dictionary

https://dictionary.cambridge.org › dictionary › english › gridlock
gridlock definition: 1. a situation where roads in a town become
so blocked by cars that it is impossible for any traffic to move:
2. a situation in which no progress ...

Can you give anything other than the most far-fetched real world
example of such a UK city?

Don't forget what a city is, of course. It isn't just a few streets
in the centre, is it?
*
* Get a life.

So you post or re-post material without understanding it.

How surprising.

Can *anyone* here give anything other than the most far-fetched real
world example of a "gridlocked UK city"?

No, I didn't think so.

It doesn't say a lot for the "new research", does it?


My local area does actually become gridlocked, this has happened about
half a dozen times in ten years or so, if I need to go somewhere local
non-urgently (on these rare days) I walk, if I needed to go further
afield then an electric scooter would not be legal or up to the job,
whereas a motorbike is excellent.


Ah... but is a local area a "city"?


Not at all, very urban in fact. I am just saying that my area actually
does suffer gridlock, and it means that leaving my road is a walking job
or motorcycle.

These efforts to get more passengers into a vehicle are hopefully successful:

https://techxplore.com/news/2019-09-...-vehicles.html

Nevertheless, during say, a pandemic, it may be nice to have backup personal transportation.

It will take awhile to get these economies of scale down to e-bikes but VW managed to wrangle the cost of an EV battery down to $100/kW-hr.

An e-bike will go 100 km on a kW-hr, +/- 30 km.

What was or still is the most costly part of an e-bike may soon be cheaper than hydraulic brakes.
