Why can i not use it on road as long as it is restricted to 15mph

the law states if it has a of road switch ie you can change the settings in the display it is not road legal at any speed.

 

so thats 99.9% of all kits you can buy of ebay ect

What about cycle paths

just buy what you want just dont kill anyone and it wont be a problem i have had a dongle now for 5 years ;)

You can not ride it anywhere the public has access to so that means private land only with no public access.

The law has LOTS of confusing parts, but the main two ones are 15.5mph max assisted speed, and 250w max nominal power. The nominal power is a slightly silly measure, but it is what the law uses. If it exceeds either of those it is not a pedalec and comes under the same rules as mopeds and motor bikes: allowed onroad with appropriate insurance etc, not allowed on any cycle paths

 

The road switch would not rule it out as a pedalec as long as it satisfied the above two constraints on all switch settings; but pretty unlikely anyone would want such a switch.

 

As soundwave says, if you ride sensibly you are very unlikely to be caught . BUT ... if something does go wrong the penalties could be quite severe (driving uninsured, etc). For example, suppose you are hit by a car while riding perfectly correctly in exactly the same way you might ride on any non electric bike. The police will be involved and might notice the technical illegality.

You can't exceed the nominal power of a motor because the nominal power doesn't change, no matter what you do to the motor. You can only install a motor with the wrong nominal power.

Sorry, I wrote ambiguously. By 'If it exceeds either of those' I meant 'If the nominal power of your motor exceeds 250w, or max assisted speed exceeds 15mph'. I'm pretty sure we agree. but good to be precise for others reading this thread. (I stand by nominal power being a slightly silly measure)

Very few cyclists would deliberately kill somebody but things can go wrong, for example:

if ppl want to run in to the middle of the road then it does not matter what he was riding, when cars first came out just look how many ppl got ran over because they thought they was invincible and there right to walk in front of traffic going at speed lol

Exactly my point, no matter how carefully you ride things can go wrong. If you've riding an illegal bike and things go wrong you're in BIG trouble, the Hanlon case is being heard in the Old Bailey and you can't get more serious than that.

 

Thanks.

Every one is jumping on Suggy !!!

Yet he hasn't actually told us if he bought the 250 or 350w version ?

He asked "Why can i not use it on road as long as it is restricted to 15mph" which suggests that he bought the 350W version, doesn't it?

the fact that you can change the speed limit means it is not road legal same as a dongle or of road switch via the settings in the display/software so the power of the motor even if 250w you can set a higher top speed via the settings means it is not road legal.

I'm pretty sure when I first responded to his first post that the post said the motor was 500w/1000w, and that was why I posted as I did.

 

I see Suggy's original post was edited yesterday afternoon. I hope that he accidentally posted wrong in the first place and that the motor is indeed just 250w, or even that he managed to change the order? I'm sure he didn't intend to order an kit illegal for pedalec in the first place.

 

I'm never quite sure what the dual 250w/350w refers to. It's a shame so many of the Yose and Pswpower kits are technically 350w; and even Woosh's BPM kit (which is why I didn't choose one).

He asked "Why can i not use it on road as long as it is restricted to 15mph" which suggests that he bought the 350W version, doesn't it?

 

No, because the 250 and 350 can probably both be adjusted except one will deliver a bit more power.

The motor winding may be different or the controlle amps will be different.

Most of these 250w motors have no power identification on them. Without any markings on the motor, it's virtually impossible to prove whether it is or isn't a 250w one. If you put a Q128 (800w) next to a MXUS XF07 (250w), I bet even a knowledgable ebike enthusiast couldn't tell which is which.

 

When motors are listed as 250w/350w, sometimes they're referring to whether you run them at 36v or 48v, other times it's just to satisfy whichever market they're selling to.

some may, the '128' is a clue.

Don't Wisper use a AKM128 250W ?

Yes, the same motor. Several recognised brands use the AKM100 also, which is listed as 350w in some places. The whole thing is a meaningless mess.

 

If you use a hub-motor, it's marked as 250w or nothing at all, it's smaller than say 9" diameter and you tell everybody it's 250w, I can't see how any expert can argue against that let alone any policeman.

Meaningless mess certainly.

 

I thought that technically the motor was meant to be marked as 250w (or less). I can't remember where I got that from, and can't find a reference.

The product marking on the same motor 250/350w I believe and others also believe is for marketing, for the EU/UK 250w is used but for USA and other countries 350w or 500w is used as they daren't think of using 250w as they feel it inferior. USA especially as bigger is better.

Meaningless mess certainly.

To conform with EN15194, an ebike has to be marked with various things, including manufacturer, speed and power; however, I don't believe that your bike has to comply with EN15194 to be legal. The law is that it has to have a motor rated at no more than 250w, max speed of 25km/h and the motor must stop when you stop pedalling. There's a 10% tolerance allowed on the speed when testing to cover measurement errors. There's no test to for the rated power that will expose a more powerful motor, though if your motor is outputting 2KW, some difficult questions could be asked.

 

I think it would be wise for anybody who's done their own conversion to add their own label to the bike somewhere with that info on it, no matter how amateurish. You can use the motor manufacturer as the manufacturer. Print it out and use 50mm wide clear sellotape to stick it to the frame or motor somewhere.

 

Example:

Bafang Motor Co. Ltd, SuZhou, China

Max speed 25 km/h

Rated power 250w

36V

.... the 250 and 350 can probably both be adjusted except one will deliver a bit more power.

The motor winding may be different or the controlle amps will be different.

This. My Yose 250W front hub kit has the speed limit in the controller set to 70kph (or something, I can't remember). But the motor windings ensure that it won't assist above about 16mph when my 36V battery is fully-charged.

 

So I'm happy that I'm fully legal even though the LCD allows me to change the speed limit.
