The European Union
Frame strength rules apply to steel, aluminium, carbon fibre, toothpaste, whatever you make a frame from... Has the Brompton frame had to be over engineered over the years? It is steel IIRC and is sold with an EU marking.

What your chap really meant to say is that steel frames are often made by small companies that can't afford to have the EU testing done. It doesn't stop Dutch or Danish bike makers making steel frames, has the UK been singled out again by that nasty EU?

Also aluminium frames are made by machines, not by women with welding equipment...

Doesn't quite add up somehow - if you know that you won't be getting a frame tested, them it can be as light as you like.

And no - it's not just EU bureaucrats - it's all of them!
We have a journalist Prime Minister, most MPs have never done anything else in their lives and the bulk of senior civil servants have an arts or humanities background. The fact that they have no interest in or knowledge of anything scientific or technical doesn't stop them ruling on such matters - and very often getting it wrong.

I wish more MPs had a better understanding of higher level science and engineering principles to help them make important strategic decisions but I don't expect them to be properly qualified in being able to evaluate frame strength rules. They rely on expert bodies to do so.

The use of Aluminium in modern eBikes has much to do with the fact it can easily be extruded and moulded. Our battery tube, wheel rims and mudguards have complicated sections designed in for strength, stiffness and to manage cables. The more complicated areas on our bikes i.e. the head tube and BB are moulded. Aluminium performs exceptionally well in both areas and can be welded together to create a strong, stiff and complex construction.

All the best, David

Can you tell me the approximate weight of the hub step through bike & is the battery removable? I will want to put it on the rear rack of a vw camper and lifting them is starting to become more difficult. Also will the smaller frame fit someone who is 5' 3"?

Was the centre drive version of this the bike the one that was touted a year or so ago as possibly having the option of having a hub gear? IIRC the new version of the Sturmey 5, which is advertised as being suitable for e-bikes, was mentioned. If so, why was the idea dropped in favour of derailleurs?

I love the idea of hybrid with mtb tyres and a huge battery. The mudguards do look a little short so maybe a mudflap to stop your feet getting soaked when you turn corners when out in the wet/rain etc. 700 wh battery sounds awesome! Could I get another to extend range, not sure if I'd need it but how much would it cost, what would the dimensions be and what is the weight? Lots of questions sorry but just weighing up options, cheers, Phil.

Sorry it seems a late response David but are those prices inc VAT or Ex? I am aiming to buy one in 2020 when released so price is important, cheers. also excuse me for mentioning the dreaded "B" word but if your manufacturing in Belgium will importing not have a tariff added also?
