ISO standard body looks at speed for upcoming ISO/CD 4210-10

From Bike Europe

Changing 25km/h and 250 Watt
This fresh start means dropping what in the past decade has been THE parameters for e-bikes – 25km/h and 250 Watt. Neupert pleaded, “My view is that we have to consider what the right and good speed is for e-bikes. At that we also have to take into account other two-wheeled road users. Then 20 miles per hour or 32km/h is the appropriate speed and with no limit of Watts as you want to be able to reach the 32 km/h also when going uphill.”

Neupert proposed this at the ISO meeting in Shanghai as a member of the Chinese delegation. His proposal fell on deaf ears at most other participants in the conference want to stick to 25km/h and 250Watt.

It's almost impossible to measure or check an Ebike's power and say whether it complies. The measurement is a lengthy and complicated procedure and the standard is not clear enough to have a maximum that you can measure against.

The sooner they drop the power limit, the better. You only need two rules: Power only comes when you pedal, and maximum powered speed is 25km/h. Both can be easily checked and enforced.

Power would be self-regulating because high power brings high weight. Without being allowed to go faster, there would be no advantage for average riders, but those that needed the higher power, because they're weak themselves, could still have it.

Why do they have to make things so complicated. If they released the power limit tomorrow and started clamping down on people with over-speed electric bikes, the only thing that would change would be fewer illegal bikes on the road.

I am 100% behind the idea of getting rid of a motor power limit, I don't need more myself because range is important for me. His logic is a wee bit flawed on speed: yes, on the flat a fit cyclist will be doing 32 kph, even I can do that on my pedelec. On the other hand no one but professional cyclists or highly trained amateurs can maintain 32 kph up a hill.

I have often said here that for my open road commute a 35 kph cut off would be more appropriate I could live with 32 kph. 45 kph isn't as relaxing, it feels great but cars don't realise your are going that fast and pull out on you.

It won't happen. Firstly the European parliament already proposed removing the power limit a couple of years ago but the Commission rejected that outright.

Secondly, as stated, the consensus over much of the world is for the 25 kph limit with many countries tied to that.

Surely in two years time, the U.K. Can do it's own thing, and maybe adopt the same ebike rules as the U.S.A. with upto 750watt motor and 20mph Speed cut off, now I would vote for that.

One of the reasons when I have not bought an ebike as yet is due to the nanny state regulations that are in place, I am sure that I am not on my own.

The USA rule is 750W maximum output power. Ours is a motor with a rated continuous output power of 250W. Those words highlighted words are important. Some of our EN 15194 certified bikes probably are not far off 750w maximum output power, so there's not a lot of difference.

I agree that 20 mph makes more sense.....
