This is the crux of my question. Is there a difference between 'mode or switch' and a 'setup configuration parameter'? @soundwave would appear to think not, I would be interested in @flecc 's view. Edit: and maybe @flecc has just answered it in a reply to another post 'and the limiting is not...

I am not trying to be argumentative and I genuinely want to get the correct understanding, so if my understanding is wrong, I want to be corrected, but I think it does matter. My understanding is the relevant 'rating' is what the manufacturer specifies and marks the motor up as. An engraved 250w...

Let's ask @Woosh, is the label on the Woosh kits a label applied by the manufacturer or is it a label applied by yourselves?

My laypersons understanding on this point is that if the manufacturer has rated and marked the motor as 250w then you are ok. The statement all TSDZ2 motors are rated at 750w is not true. Not that it is particularly relevant as per the legal rating, I did see that replacement internal motors...

And here we go again. By the above definition the Tonsheng and Bafang mid-drive kits and probably many hub kits allow you to change cutoff off speed and wheel size through the LCD. In practice I can't imagine anybody caring much but it opens that window of uncertainty again. I'm sure there are...

Well, that explains a lot! Thanks for doing this test, and makes a bit more sense why the 1st bar lasts for soooo long. I know why when I was on 3 bars the motor was struggling on hills. Unfortunately, flashing will void the warranty so I'm not especially keen to go down that route. It...

Well, I'm looking for 3rd party insurance and would not go with British Cycling for other reasons, but their policy states: (7) E-bike (Electrically assisted pedal cycle) must have pedals that can be used to propel it, the electric motor should have a maximum power output of 250 watts or...

Hi, As I am now riding more I think I should get 3rd party insurance. I was looking at joining Cycling UK who provide 3rd party insurance with membership. I believe my kit based ebike does not disqualify me from the cover. Anybody got any other suggestions or is anybody aware that the Cycling...

Well, this is indeed comforting and had hoped this was the case. For what it is worth, from a personal perspective 15.5 mph cut off and a continuous 250w rating are no problem for me and I feel precisely zero inclination or need to step outside of this. I have not installed the throttle either...

Apologies for dredging this up. Is anybody aware of a case when this has been challenged? I can imagine a case involving say an accident and resulting injury and a keenness to put doubt on the roadworthiness and legality if the bike as it happens to be a kit? You can see how tempting it might be...

Emmebrusa - TSDZ2-v20.1C.2-update-2 for VLCD5-VLCD6-XH18, I think... Motor.c line ~768...

I made my choice to buy from a UK company with CS and a warranty that may actually be usable rather than importing. Tbh, it was mainly the lack of availability of batteries of a suitable quality and difficulty sourcing a 48v 250w motor. I don't regret the decision to buy from the UK. C This...

I know osf is not something that will ever be covered by warranty. For the tsdz2 I suspect getting new firmware from the manufacturer is unlikely. Out of curiosity I had a little peek in the OSF code on my phone. Field weakening is started to be employed over 48 rpm and progressively up to 105...

In practice I think then that only the 1st half of the battery capacity is of practical use to me. The assisted cadence on the 1st couple of bars is ok but by bar 3 it was not nice. I think 80 to 90 rpm is comfortable for me. Less than 75 rpm just feels completely wrong, especially on hills -...

So, I understand the calculation for wh per bar of the display - that's simple enough. My question is about assistance at various cadences. I know the tsdz2 motor notionally like to spin at 4000 rpm ( which I am guessing is at 48v ). So presumably it is happy spinning somewhat faster at 54v on...

I would be interested to know how much use folks get out if a TSDZ2 before I've bodged something with damp proof course wrapped around the housing and secured with cable ties. It ain't pretty but I think it will deflect the worst of the water. C

We'll, waiting for my colleague to take a look in his shed this weekend. I have the flu so in stuck in bed . I think the last time used it he managed an Achilles heal injury and spent some time in a boot. I think he has gone off cycling...

@Bikes4two, looking at your photos it looks to me like a perfect arrangement for rusting out the spindle bearings at the pinion gear! Any water that does get it can collect in the convenient little pocket in the housing for the pinion gear ensuring it can sit in the water forever. It feels...

Riding home last night there was a lot of standing water - fortunately the roads were deserted so I could weave about. As I understand it the main weak points are the seals under the chainring. These are not particularly easy to protect with a deflector (other than mudguards obviously). It...

Tbh, I suspect I am on the cusp of not really needing an ebike. I suspect if I had a decent road or gravel bike I would do ok for regular cycling. Tonight I cycled back from the pub after caving with 2 X 25l panniers crammed with totally mud caked cave equipment - the mud is quite something. The...
