I'm not sure your average copper, at a roadside stop, is going to be looking for a paper trail. What I'm interested in is not getting my bike taken away by some pedantic jobsworth and it seems some judiscious labelling will achieve that. As to maximum continuous rated power, if the motor does...

So, EN600034 is a pass or fail. Ergo a motor that does not overheat at 800w will certainly not overheat at 250w and, therefore it would seem, can quite legitimately be labelled as 250w (if that's what the duristriction demands). As it's the label that the authorities will look at, that's the...

!: Any battery, of the right voltage, will work with that kit. If the controller is dual voltage it can be 36 or 48v. 2: Woosh kit will be plug and play with lots of back up and are known for good customer service. It will be legal. Regarding volyage. A 20Ah 36v battery is 720 Watt Hours, a...

Sturmey, mate, take the chain off a mid drive and the level piece of ground and stop watch aren't gonna be much use . Buy a believable motor and sticker it accordingly. Here's one I did earlier. Take out the bleedin obvious, put in the 'yeh, I can believe that'...

Brilliant ! Not many unquantafiable variables in there ! For every day use, the power of the motor is what the sticker says it is. Buy a resonably sized geared hub and put on a label that says ' 250w' and 'Hoofrungdung Motor Corp' on it and enjoy it, 'cos the only thing practically measureable...

Exactly so. They are also capable of going far faster than the national speed limit, but non has ever been confiscated because of the ability to do so. My Ezee conversion in level 5 and on the stand, wil register 19mph. But that's on a cycle computer who's speed registration is dependant on...

I bought my Aikima motor from TopBikeKit. Got motor,controller, display, pas, cables etc.all from them. Bought the motor bare so had to build it into a wheel. Never done it before but it's not such a dark art and all went well with some help from youtube and advice here. Have a look at...

But this still leaves us in the place where, so long as the motor has a 250w label, it's legal. Mainly because there is no roadside test the authorities can do to check this. Input power does not equate with output power, but that's not what the regulation states. I believe the wording is...

As a punter, I buy a hub motor. It comes with a sticky label on it. How do I know who put it there? Was it the manufacturer or The middle man/supplier? Who can test the veracity of what it says? My own AKM motor now has a label stating 250W which is absolutely bloody meaningless - yet makes...

Don'tcha just love nutty garden shed british inventor/engineers. Looks liks he's using a direct drive bike motor as generator on one of the versions. I've got one of those in my shed mmmmm !

Agreed, the legislation is very badly framed. I suspect this is a result of career politicians and civil servants who come out of university with politics, arts or humanities degrees, never have a proper job and claim authority they have no substantia for. The recent utterances from the covid...

Your controller is 36v only. To get more speed you will have to buy a new 48v controller together with a new display (they always come paired). Then you will need a 48v battery. The motor will not be bothered by the increase in voltage so long as the current supplied is not too high. As your...

Sounds like what your son actually wants is a motorbike and it just ain't legal' So, I too would go the conversion route. Find a bike he likes, some sort of mountain bike or hybrid would be good (either with hydraulic brakes or you can install them). Buy a kit, rear wheel hub or bottom...

OR go with a hub motor, generic controls and install your own kit and keep a few grand to go places. What this guy is calling for makes sense but is never going to happen. The industrial lobbying might is too big and the understanding amongst politico's too small.

If the bike isn't working, then there is a strong case for return/replacement. If you alter it at all you will invalidate any warranty. What is the bike not doing that you expect it to do? If you want to persue a fix, we are going to need some photo's of the bike, it's display, motor (with any...

Agreed. There used to be a forum member who lived on the French/Spanish border. He regularly cycled into Spain and told us many time how strict the spanish police are. So it's 250w motor with 25kph max speed if you want to keep your bike.

What wet food guys? We're currently having trouble with our 11 year old ginger tom Smudge. We've swopped from Felix to something called KatKin. It purports to be lightly steamed fresh meat and is received frozen. When defrosted it has the consistency of pate. At first he went for the...

Your Galway scientist is talking from his understanding of how lithium cells behave. In that sense he/she is correct. However it does not take into account the battery management systems used in e bike batteries. These only balance the multple strings of cells at the top of the charge. So...

Bikes really work when ones employment is local, rather than having to commute 1 or 2 hours each way. Never seen the rational myself.

If those guys can't get spokes then they are not even part time bike mechanics and there your trust ends. Spoke replacement and even wheel building is not as difficult as made out - I know 'cos at age 70 I've just done it for the first time. Corrosion on the charge socket will be because of...
