I think it's just a glitch/misprice by the seller, all the other displays kits are much more, it's even less than the bare motor price !. If you select UK delivery, it adds VAT at the checkout, choose China shipping (VAT paid by seller) to get the cheap price. As I said, ordered mine last weekend, delivered Wed from the UK warehouse, they ship from their nearest warehouse regardless of where you select

 

Thanks for pinting this deal out, I may well have to bring my second bike plan forward!

That's pretty poor really and no wattage rating noted either, tbh it could be any of their motors so no way of proving either way whether it complies or not.

I'm not sure what purpose having a wattage label would serve for the TSDZ2 (apart from conformance with EN15194) given that there is only one motor whose power is determined by firmware and which is really not difficult to change?

 

I've no knowledge of the Bafang mid-drives but have I read that their motors are engraved with the power rating? Even if they are, is it not a relatively straight forward task to change the Bafang firmaware for higher power output too?

 

So is an engraved motor any more legitimate than one with just a stick-on label (which can be changed or supplemented with an eBay purchase)?

I haven't been stopped yet by the Police - I thought they would a few weeks ago when a Police car followed me very slowly for about a quarter mile. My bike is completely legal AFAIK, and my plan if stopped is to point at my limited speed on the display and the 250W engraved under my Bafang BBS01b motor. I don't know how a conversation with the Poice, would progress if stopped while using any sort of ebike, doesn't seem to be reported here.

Thanks for posting this. I've ordered the 48v version but what battery is recommended to go with it?

One with a 20 or 25a continuous rating (not peak rating) the current draw is 15 -18a for the controller.

Mine arrived yesterday after ordering last weekend. It was a bit of an impulse buy, I don't particularly have a need for an ebike but have fancied building one up for a few years now.

 

I just need a battery and then to decide whether it goes on one of my existing bikes, or whether I buy one especially. I quite fancy an On One Bootzipper as long as I can get the 44t chainring to fit

Thanks for this. Are there any particular batteries and/or suppliers that are recommended? I'll be honest, I've spent the last week googling batteries and I'm not really any the wiser. I was hoping to keep the price under £300 buy if I need to pay more for something reliable then will do so.

eclipse bikes is start.

Or speak to billym1967 of this forum as he builds batteries also has an ebay presence.

Hi,

 

Just by way of a quick update, in looking for a battery one of the suppliers I emailed replied to my enquiry and advised that Bafang don't do a 250w 48v kit. Has anyone come across this before?

 

There is a sticker on the motor with '48v' but more stickers in the box which state 36v. The engraving suggests it really is 250w rather than anything more powerful.

 

Thanks

As i explained the 48 v is the 500watt with a sticker

Purchased one from a German ebay seller with stickers that also stated 250w 36v its not legal and if you use the stickers it a bigger offence under uk law

Woosh advertise and show a picture of one engraved as 48v 250w. It may well not be available though, their website does quite often get a bit out of date.

Thanks for your reply. Just to check, even though the engraving suggest 250w you think it likely that's it's really 500w?

The settings on mine showed current set to 18 amps at 48v thats the same as the setting in the 500w version the 750watt is set to 24 amps

Hi, can anyone confirm whether the 48v "250W" version is legal in the UK? Some have mentioned it is actually 500W. I am looking at doing a conversion and don't want risk getting into trouble in the case of an accident or something.

That's a hub marking, not mid drive.

Sorry ... silly me.

Aha! So that's where those are hiding! With that 250W engraving, it would pass a roadside copper inspection... if the speed limit was legal on the display - but they might throw the book at me if it was taken in for a thorough examination, after a serious accident; Nonetheless, tempting for a cargo bike...

I'm probably going to go down the 48v 250w route on a listed tdsz for my new cargo bike, went on a 402 mile round trip yesterday to pick up a little used immaculate 18 month old Kona Ute in a beautiful Burgundy colour.

I have an option of using either a Bafang cst or a akm128c from one of my other bikes but have decided mid drive will likely be best for this one.

Kona Utes are very well-made cargo bikes! Capable of heavy loads:

The Ute is a similar price to the Mundo, the Big dummy is another though is 1k dearer to buy.

The Kona Ute will get you out of many a sticky situation while carrying honey, it'll look sweet doing it too! Have you got the large pannier bag? Big tubing on the frame inspires confidence.

The cavernous bags are a std fit on later bikes so yes I have them.

I reckon I can fit 3 decent carrier bags of shopping in each one compared to normal panniers that can only take one bag each. I have a bakers tray that can sit on the rear deck to carry extra items and of course the 1m x 0.6m flat bed carryfreedom to tow behind it. Each side is approx. 50L in volume.

It's great that they're standard now.

Hey I've got one of those in the loft! Was wondering what to do with it

 

That's a very large volume of honey and stuff! Are you absolutely certain that the 250W 48v Tongsheng will be up to the job?

Edited November 10, 20214 yr by guerney

Should be more then ample 48v x 15a is 720watts of power with the nice low gearing no problem. If one can ride unpowered then some extra power is only an advantage and the Tongsheng is approx. 6 or 7X the power I can out put.

I'm really looking forward to seeing a photo of your fully loaded and electrified honey haulage ensemble.
