--------------------------------------------------------------------------------
I give up trying to get my golden kit up and running I bought a 1000w
cyclone kit. I have it up and running on two 24v nimh,s giving 48v. I am not sure the batts can handle the fast discharge as the motor cuts if i throttle up and comes back when i throttle back the batts heat up affter a few minates also. the bike is a 26" full supension mtb . Any ideas?
thanks
Al.

Get legal! or buy a motor bike!

That's enough of that language "aqs".

Folks,

we should remember that not everyone is based in the UK and in other countries there will be different rules regarding the speed/power of electric bikes.

So please be constructive and also note that offensive language will not be tolerated, so keep it friendly please!

 

[ITSPETEINIT]

Foul!

I cannot bring myself to quote what I am referring to ......... the posting by "aqs"
I consider myself to be fairly (I mean even handed) tolerant and worldly but I found his posting truly offensive.
I note that at this moment no apology has been posted by him.
He did not disclose from whence he comes - it may tell us something.

It may help aqs to know that my terse reply to his request for help was based on quite genuine concern for anyone (regardless of what the law may permit in his location, or an intention to ride off-road) who wants to run a 1000 watt motor on a pedal cycle.

Location is Northern Ireland I think. I took the reply to be slightly tongue in cheek but it does show you how careful you should be with postings. You can get away with this sort of thing face to face or use the smilies On a constructive note there are other forums specifically for those wild electric bike and a question to them might work.

I'm sorry Harry, but I cannot see any justification for the use of such foul language, even if provoked. Face-to-face or tongue in cheek makes no difference- - it is abhorrent.
The Forum rules EXPRESSLY forbid this even by innuendo, asterisks or smilies (although I cannot see what there would be to smile about).

Perhaps this should really be for a different thread.

Aren't we being a bit harsh here?

I gather that the individual concerned made an angry retort to the plain dumb and provocative response he got to his quite reasonable question. whilst I wouldn't condone the use of inapropriate language, why did the initial responder choose to be so provocative (and factually incorrect)?

UK law (which I assume also includes NI) absolutely does not forbid the fitment of a motor with a power rating of 1000 watts in any way, shape or form. In fact the law makes no mention at all of the motor maximum power rating.

The law does require that the power delivered to the wheels be limited to 250 watts, but the vast majority of ebike motors, quite reasonably (and essentially) have a very much greater motor power rating, to allow for the peak power that needs to be delivered for short periods. All ebikes that are power limited to meet UK law do so in the controller, not the motor, as far as I am aware.

I suggest that we all be a little more tolerant and stop playing policemen - if an individual chooses to break this law then it's purely a matter for his own conscience, not some overly-righteous and ill-informed fellow poster.

I still think a 1000 watt 46 volt motor on a pedal cycle is dangerous for the rider and third parties, legal or not.

And the CTC summary of the rules is as follows:

The vehicle must not weigh more than 40 kg if a solo bicycle, or 60 kg in the case of a tandem or tricycle.
The vehicle must be fitted with pedals, by which it can be propelled.
The vehicle must not be fitted with any sort of motor other than an electric motor.
The continuous rated output of the motor must not exceed 200 watts if fitted to a solo bicycle, or 250 watts in the case of a tandem or tricycle.
The motor must not propel the vehicle when it is travelling faster than 15 mph.

I agree that peaks of higher than 200/250 watts are permitted, but the impression I have when anyone fits a 1000 watt, 48 volt motor and needs a battery which will handle a high discharge, is that the bicycle is to be used at speeds more suited to the traditional motor bike. And for me that impression holds good even if the controller is capable of accepting 1000 watts/ 46 volts yet still keeps the average output down to 200/250 watts.

 

[Jeremy]

Why? My motor is rated at well over 1000 watts (I think that it's been shown to still be reliable at around 1,500 watts) and is completely and absolutely road legal and as safe as any other ebike. Mine runs at 48 volts too.

The motor rating has little to do with the power delivered, this is limited by the controller. In my case, the controller limit kicks in to limit power and speed, just as it would on any other legal ebike.

The provocation was certainly there Jeremy, but the response was as foul and abusive as I've known, and I'm an ex British Army sergeant, so hardly a stranger to such expressions.

A harsh response to provocation could have been made without resorting to such means.

[Jeremy]

I agree wholeheartedly, Flecc, but the chap was only innocently asking for help originally, as many of us have done.

The internet is an odd environment in many ways, as it unfortunately gives those with less self-control the freedom to "type first and regret later" much more readily than anyone might in a face-to-face interaction.

I actually meant Rooels response was tongue in cheek. I never saw any foul language response as I suspect it was long gone by the time I got home so I cannot possibly comment. If it was foul language then the rules are quite clear but my point was really to be careful how you write your post as it can be misinterpreted.

Of course Jeremy, but I responded very quickly to that posting and there's a clear Delete Message option available for those with second thoughts, which wasn't used, before or after I posted.

I'm going to be very unfair in some eyes now, but I think buying a 1000 watt motor which the supplier clearly says is illegal in our market (their recommendation being the 180 watt) and a posting of this type do tend to occupy the same territory.

A bit like the way over loud car sound systems, illegal car cruise meetings and irresponsible on-road driving go together very often, this latter group being those who most commonly yell abuse at cyclists like me.

[rooel]

And the deleted response was just what you would expect from a road rager too.

 

[Jeremy]

I don't think you're being unfair, Flecc, but would dispute the legal aspect.

After all, it's not the motor power rating that's regulated by UK law, but the power actually delivered when in use. As I mentioned before, my hub motor is rated at a ridiculously high level, but that has no relevance whatsoever to the power it delivers on the bike, which is limited by the controller to the legal limit.

Looking around, many (perhaps most) ebikes have motors that will easily exceed the UK limit if connected to an unlimited controller, in fact, I'd go as far as to say that it would be possible to make almost every ebike in the UK illegal with a little tweaking of their controllers. Many are already technically illegal because they don't shut off electric assist at the legal speed limit, as we already know.

[flecc]

Of course Jeremy, but I think there might be some misunderstanding from my brief use of the word motor. The Cyclone are kits, and the only one that Cyclone says is legal in our market is the 180 watt kit. All the others, 360 watt, 500 watt etc, couldn't meet the average 200 watt (UK) or 250 watt (Europe) laws in their standard installations. The 360 kit controller/motor combination is typical of the kind found in many parts of the 20 mph US market.

as far as I am aware, it is perfectly legal to own any vehicle you want, as long as you use it legally, so you can have a 5000W electric bike on private land and that's fine. if you live next to a motorcycle track, it's fine to have a 5000 W bike. personally I have a 400 W bike and I can limit it to 200w/25kph for road use...

very interested in hearing about a 1000 W bike!

Sorry Harry. I wondered whether or not you had seen the "foul" posting judging by you comment. I withdraw any criticism of you either in fact or implied, unreservedly.
What you missed, by the way, was the ordinarily polite person's reaction to it when reading it - it was pure 'gutter language'. I was literally 'winded' when I read it.

Yes: I find when reading postings that I have to 'elect' for a certain interpretation because the subject of the matter is not clearly identified. I do it myself in my hurry to get down what I want to say - not reading it from the readers position.
