+1. A better way to cater for being in a hurry is to leave the battery charged to around 60% so that there's less to top up when it's needed, a basic socket timer is useful for that. A substantially higher charge current may not be good for the cells and it's less effective at higher State of...

How many wheels? ;)

With everything connected ready to work, for every part post a photo showing what it is, with the label if it has one. Post photos showing details of every connection, showing the wire colours on both sides of the connector if you can. Tell us about anything that can't be photographed (like...

Assuming that Woosh is one of the businesses contributing towards hosting this forum that would be asking for reasonable etiquette, but still I don't think it would work in their favour. It comes across quickly to visitors here that Woosh supports their products to the hilt, equally that those...

Is this as it reads, that a buyer isn't tied to their employer's choice of scheme, and won't be tied to dubious buy-back terms either?

Fine throttle control is like close gearing, you wouldn't call 30 speeds necessary but sometimes I miss them when I've 8. I often ride with the meter showing around 40W and it 'feels right'.

I'm looking forward to testing it when mine arrives.

Not sure I understand, you're saying without an LCD the PAS level defaults to 1, giving max battery current = 13% of controller 'max' rating, and a wheel off the ground spins up to full speed when the pedals are turned, yes? What happens if you repeat that adding 50% throttle, do you get (up...

I thought KT controllers defaulted to TS aka current control, throttle would cover 0 to WOT and a scooter won't need PAS levels. Aside from the speed limit what best LCD features will he miss out on?

The Batteries section in these CAA regs begins What is a lithium battery? so it seems fair to ask What is a Brompton? If it's a Mobility Aid for disability, health or age the limit's 300 Wh, better still if it's Lithium battery-powered equipment capable of generating extreme heat it seems to...

Yes great fun. My guess is that if the cells are already in balance the BMS blocks the charging current rather than bleed all cells evenly. The battery and thermocouple need thermal insulation, balance current is small and the cells will warm up during charging. But what if you were to open...

Another way to look at it is that a motor effectively takes up to X% off gradients. For a commute you already manage most systems/kits should make it a fair bit less tiring and slightly faster. Designing a system to let you do what you couldn't before or make your journey significantly...

Happy Christmas to all and especially to our two supportive Traders, wishing you a successful year to come.

Those are called shaped ebike connectors, although extending the wire is another option. https://www.ebay.co.uk/itm/145197004102 A pair on eBay will set you back £9, on AliExpress £3.80 to Europe but not available to the UK. See...

That's shocking, could an American household really survive on 1kW? And wasn't the real Matheson scandal that anyone would dare charge £11000 for 5 or 6 hours data roaming in the first place?

@BB, look again at the other criteria you gave for What counts as an EAPC. The 15.5mph assistance limit is hard and fast. All the rest (example: "the maximum speed of the bike") explicitly ask for a declaration of nominal value, and each would have a range of 'true' values if taken literally...

"a plate showing the instantaneous voltage of the battery" ;) The acceleration test measures what the bike does (20 m in 6.9 seconds) rather than how it's achieved (250W). Would it have been better for the rules to focus on behaviour generally?

The weight limit for bicycles was removed which would barely make sense in the context of a hard 250W limit. We should all be hitting the 'Report a problem with this page' button. EAPC regs, DfT guidelines

There's the question of heat treatment (IANAM) and the bracket design might be copy protected to stop bolt-on interfaces being sold. Although how you'd protect a triangle of holes is beyond me, and what's to stop someone making an oversized interface for the buyer to fit with standoffs? Perhaps...

A larger sprocket would be cheaper but mean losing that lovely chaincase, hence a smaller chainwheel. But most hub gears have tight limits on the torque they'll tolerate so if the gearing changes by much the Nexus could be shortlived (like mine). I'd size up the road clearance of the centre...
