I've got a geared hub motor that claims 250W and 65Nm but its on a 20" wheel? I guess on a larger wheel 700c the torque would be significantly reduced. I bought it on Amazon but I found the same wheel on aliexpress and they had a chart showing how torque varied with wheel size. They were...

Any ebike sold from within the UK officially must be fully certified. I guess perhaps you have Chinese sellers who set up a despatch warehouse in the UK might get around it somehow. I.e. the payment goes directly to China and they despatch from within the UK. Generally though the way to bypass...

Your first point about range of gearing is a mute point as a hub motor ebike can easily have a 3x crankset if you wanted that where as most if not all mid-drives are limited to 1x crankset so more limited gearing. I take your point if that is what you are trying to make that mid-drive power is...

250W shared by 15A is less than 17 volts so is this a reading after the controller has dropped voltage in order to maximise current/torque? Is this a 36V battery? The more you push amperage the harder the individual cells work, this shortens their life and could lead to some cell failures over...

I pretty much totally disagree with your points except the one where you compare the ford Escort to the Ferrari as of course the Ford Escort is far more reliable and dependable than a Ferrari which many have burst into flames spontaneously and are hugely unreliable. That is not a good example...

You can have phone apps and browser extensions for cashback sites but you can also just use them by going to their web page, signing in and then clicking to the site you want to purchase from. I use a adblocker on chrome so I'm not seeing adverts. They make their income by sharing the affiliated...

Huge amount of stuff is sold from China to the UK and obeying tax laws seems a mute point when the laws in China are very loose when it comes to commerce. I'm sure I had something recently that I paid tax on but there was a invoice included to a much lower amount but can't remember the details...

I've had that as well where a battery was despatched from Slough I think so they must have shipped them in bulk to there and then used local couriers to send around the country. This might be more efficient rather than a tax dodge but I'm suspicious. Everything I buy from Aliexpress now pretty...

These don't appeal to me at all, limited and expensive for what they are and highly proprietary. The best feature is they can be moved to different bikes easily so any bike you have I guess can be quickly configured as an ebike. Hopefully a cheaper more generic version will come out. Perhaps a...

I wonder how tax payment works from China to the UK? Surely they could still declare the value as lower than sold and just pay the lower amount of tax as when you pay its on aliexpress's own payment site unless credit card companies forward the details of the purchase to the exchequer. I wonder...

The UK has to prioritise its own manufacturing and farming in order to reduce our trade deficit and huge debts. This should be the number one priority by far of any government just like it was after world war 2. So any politician commited to manufacturing in the UK is great but I'm not impressed...

I do a bit of both so build up rewards, vouchers on the app but then do the final purchase on a computer so I can go through a cashback site like topcashback to try to maximise my discounts. So I played that game where you get points on the phone and I bought vouchers with them and the remains I...

High end bikes are proprietary but cheaper bikes are still very open designs with the ability to use a wide range of different components. High end bikes are typically performance bikes either road or off-road so they are destined to be shorter life anyway, weak light road bikes or complicated...

I assume they only allow you to use a few coins per order based on value as when I was playing about with an order before placing the order the bigger the order the more coins I could use and it didn't allow a lot to be used at one time. I placed one order and I got a discount from aliexpress...

Most of the world rides ebikes with twist and go throttles its the norm in china and India which is a huge amount of people in itself but goes well beyond that. There is no reason for it to wear out the batteries prematurely because you have full control of electric power so you only need to...

Isn't that how the Switch pre-order works, you get a substantial discount for pre-ordering over their normal prices but have to wait 6-8 months or something. Still seems very expensive to me compared to sourcing the components individually which would also be less proprietary and easier to...

Any bargains on the aliexpress singles day offers? I've bought some stuff on there. Using as many vouchers as I can use and also going through a cashback site. Yes the VAT still grates a bit but overall some very good pricing.

The Nexus 8 is not that strong and you do hear of early failures even without using a mid-drive motor. I guess if you aren't that heavy or powerful hacking it to give you the 60Nm is ok but they have downgraded it to protect the Nexus from failure. I think Bosch limit the motors typically used...

Got one too. Just ignored it. I also get quite a few youtube messages pretending to represent channels I watch and comment on offering prizes. Seems to be more of these youtube and forum scam messages recently. I wonder how the scam works I guess you have to pay postage to receive a free...

Nice scenery but need more close ups of the bike itself. Cockpit and drivetrain etc. :)
