The last scientific assessment I saw on this was the BMJ review , published a few months ago https://pmc.ncbi.nlm.nih.gov/articles/PMC9420317/ which considered the evidence for the two alternative theories.

There are significant feedbacks when you increase CO2 (eg the warming from CO2 increases water vapour, which is itself a greenhouse gas) but the gain is < 1 so is not unstable. A doubling of CO2 will lead to an temperature increase but will reach equilibrium (IPCC AR6 estimates 3 Deg C most...

That's a really good instructional photo, showing that it needs pushing in further, should bookmark for when people come here with problems

So ideally, yes, would be able to mount battery on downtube. Found an extra small 2020 specialized rockhopper expert x2 (29er) locally for £150 with uprated air forks and dropper post. Just asked for the internal dimensions of the frame triangle to see what battery I could fit...

Yeah, on road and off road but on tracks, bridal paths, not serious mtb - they say can be done on gravel bikes and hybrids

This is the itinerary https://www.eventcreate.com/e/coast-to-coast-2025

I've been having a look on Facebook marketplace and Gumtree and there are quite a lot of Trek Marlin 5s and 6s extra small (my sister is just under 5', her current KTM Macina (size small) is too big for her - I'm 1' 5" taller than her !) They have hydraulic disk brakes, Altus 2* 8 or 9 speed...

So my sister (55yo) is doing an organised coast to coast e-bike ride in June (mixture of roads and off road). She currently has a 12 year old plus KTM Macina with rim brakes , hub gears and a Bosch Classic+ mid motor and a PowerPack 400 Frame battery that she uses for commuting to work. So...

For my Boardman 29er with Bafang mid drive conversion I bought a Sunrace cassette with high tensile steel sprockets (thought higher strength more important than lighter weight with a mid drive) https://www.ebay.co.uk/itm/115406896819 I also bought a KMC "e-bike" chain...

Ok, but the battery is currently mounted on the handlebars (potentially being replaced with a battery on the seatpost), can he just follow the current battery cable route for the LCD wiring ?

@saneagle @Nealh @thelarkbox So if the op bought a Yosepower 36v seatpost battery (£173) and KT controller, display, cable and pedal sensor https://www.ebay.co.uk/itm/256369636190 £52.20 + 10.80 postage That would potentially be a solution ? £236 total

I know it is a kit but https://wooshbikes.co.uk/?tsdz

Is there anything special about the Mahle system or would a 201 rpm AKM-75 hub motor in a 700c wheel with a KT controller and 36V10Ah bag battery be as good / better ? (obvs - wouldn't look as cool)

One other thought I had was that if you have no display then I think you will get full power from the controller until you approach the assist cut off speed (25km/h). If you had a display, these typically have pedal assistance levels that you can set in the display to suit yourself. This will...

So it shows how much things have come on, I have the 2012 26" wheeled , full suspension Scott Genius MC40 (which was pretty easy to convert to a rear hub drive Ebike with 48v 20ah down tube battery) Mine was 12.5kg before I converted it (Aluminium Frame)...

Yep - If it was me, I would try a new battery with that controller, if that didn't work, then buy a matching controller/display/ pedal sensor There is lots of options for 36V batteries - bag battery for lightest weight , rack battery if you have rack mounting points, seat post battery, bottle...

Do you have an existing display - how do you turn it on at the minute ? (usually displays and controllers are paired.) There is usually a pedal sensor that goes into the controller. Sometimes there are cut offs from the brake levers so the power cuts out - I can't see them on yours Ah here...

Probably OK if the width between the front fork dropouts is 100 mm (some folders it is 74mm)

Here's a couple of my attempts All seemed very easy to do https://www.pedelecs.co.uk/forum/threads/converting-a-little-folder.47261/ https://www.pedelecs.co.uk/forum/threads/converting-folder-bike-to-cassette.47893/...

That's got all sorts of possibilities ! Looks like a standard connector to the rear hub motor wheel So - you could just leave the existing controller and display and use a new 24V ebike battery - all sorts available - has your bike got rear rack fitting points ? or possibly...
