That's interesting, is there actual evidence that 4-wheeled EV's are prone to catching fire while charging?

Yikes, who'd want to carry 16kg 30cm off the steering axis with their tots on the back??

'E-cycle' has been in use on gov.uk, they've listened to you and it works well I reckon. Battery safety for e-cycle users - GOV.UK Proposed changes to legislation for electrically assisted pedal cycles – outcome - GOV.UK ... concerning electrically assisted pedal cycles (EAPCs) or ‘e-cycles’.

It's best to work out details before ordering if you can, as you can see each option has its drawbacks. If a silverfish won't fit your triangle but the cell pack does with room to spare you could build a custom case, that may do better all round. For a 750W motor another thing to think about...

If I understand correctly the battery you've bought is a welded cell pack so it probably won't fit the downtube cases you mention because they're a close fit to their chosen cell-holder layouts. Roll top panniers have the edge over frame bags for waterproofing, and to absorb local impact you...

Simpson's paradox:

Just chiming in to mention that most fuse ratings are continuous, i.e. 30A indefinitely but plenty more briefly so they don't offer "no chance" protection. Good luck with the heel-dragging, meanwhile that First Step's a good 'un.

Very nice, and if the rear's grabby it adjusts CCW by the orange dot. But I can't FTLOM see how you'd get even a 25mm hex bit into the upper front adapter bolt with the old caliper on there, or even a ball-ended wrench. Do tell! P.S. Articles explaining the adapters here and here.

Well that's embarrassing it's only in the very next clause: "If all braking devices (e.g. levers, back pedal) are equipped with cut-off switches, the cut off distance shall not exceed 5 m." EN 15194:2017, 4.2.13.1 c Hadn't noticed 5m and a big improvement on 2m. I guess "all" must mean 5m cut...

We need to be careful when talking about charger connections to distinguish between two separate situations. There's a million or so ebikes in circulation, ~ 7 years worth of current sales. Many have an inadequate BMS that leaves the battery vulnerable to overcharging and for those legacy...

Eh? "Assistance shall be cut off when the cyclist stops pedalling forward and the cut-off distance shall not exceed 2 m." EN 15194:2017, 4.2.13.1 b

ChatGPT led to what I'm looking for, I hope our legal eagles will agree there's some benefit in it. A: Govt Guidance including Buying an e-cycle conversion kit (February 2024). States: check that the kit complies with the UK e-cycle regulations and with British or European standards. Links...

That's purely the law though, and that's why it's important to be able to refer the police to any places the Govt have mentioned kits etc. Those may not have legal weight but could reasonably be construed as acceptance and implicit 'instruction' not to confiscate in the case of kit or DIY...

I'll be fine with a 4mph throttle but have twice - what is it about roundabouts? - entered, got cramp and crossed bolt rigid at walking pace :eek: Throttle aside the nice thing about that DfT advice was it saying specifically "the [approval] regulations will be directed at the manufacturers...

I might be misreading this as saying an EAPC-like SVA'd vehicle can be used as an EAPC. That seems to differ from the DfT's response to HelenJ which was that: "if you convert a pedal cycle which has already been ridden on the road to “twist and go” operation, it does not become subject to type...
