Clearly breaking the rules on eBike\Pedelec regulations, in the UK, is not acceptable, and I am sure no-one on this UK forum would encourage that. However, there seems to be no evidence that its the 'illegal' motors that are catching fire, its the batteries. And there is the problem, the...

Thanks for checking. So the Q70 is lighter than some @ 1.45Kg, with the AKM74SX listed at 1.6Kg. Interesting.

Does the motor itself weigh 1.2kg ?

Possibly. When I got the 2nd hand Bompton it came with all the old stuff too, so I have a spare set of steel forks, in case.

I was tempted to buy the T - Line, but an electric conversion does not seem possible. Apparently the titanium forks that are available from Brompton wont fit on the T-Line. The Velospeeder possibly, but that would void the warrranty, which potentially is a lot of money to through away given...

I did'nt see the gate ? Bit like Boris saying "I saw nothing".

A Brompton Electric C-Line is quoted at 17.4kg plus; https://www.brompton.com/electric-c-line So by the time you add the rear rack and some better easy wheels, my Swytchified one is around the same weight. Although with the battery bag removed its around 2 - 3Kg lighter. However, that for all...

I use one too. Plenty stable and strong enough for an eBike.

I dont. Lipsmacking, thirst quenching, ace tasting, motivating, good buzzing, cool talking, high walking, fast living, ever giving, cool fizzing, Pepsi.

I have a folding eBike, a Swytchified Brompton. To me at 18Kg with battery, its pretty much the limit of what can be picked up, put in the back of the car etc. Even without the battery pack (-2Kg) its still a struggle to handle. Maybe its old age.

If your in the UK, I dont think there is much you can do. Unless your using the bike on private land with the permission of the owner. 250W is the limit in the UK for an bike using the roads.

I think most people can use a bit of common sense to work out which is safer. Given the average state of the roads these days which is likely to be more stable, and resistant to potholes, a large wheeled cycle, or a tiny wheeled scooter ? Which is likely to be more stable, someone riding a...

Yes the batteries from Whoosh are very good value ++++. Whilst my electronics experience is long, around 50 years, initially as a as an professional electronic designer and then looking after the electronics side of manufacturing the BBC micro, DIY battery builds are not on my horizon. And...

Original, really ? https://www.snopes.com/fact-check/wd40-ad/

Thanks, they have some good stuff. The 'Tubular' controller looks real light ................. https://www.topbikekit.com/10s13s-36v48v12a-yg-kt-6mosfets-sine-wave-controller-kt-tubular-controller-p-1039.html?zenid=rt3pp85vpvg0o6oe3r7dc11fg7

True, hence the question about the Velospeed. Does anyone sell Brompton Q70 front wheels ?

No tyre and tube 2055g. Standard Brompton Wheel, no tyre and tube, 615g

eBike batteries sugegsted a 10S2P pack of Sony VTC6 for 6Ahr at about £300. or Panasonic BL3350 for 6.7Ahr. Thats enough capacity and with 20 cells at around 50g each, its quite a light pack too.

Anything out there lighter than a Q70 front hub motor ?

OK, mine was a Swytch. The weight of that wheel above a standard (no motor) Brompton front wheel was 1440g.
