I think the basic idea is this: manufacturers would fit 350W and 500W motors to their S-pedelecs. In their tests, users reported averaging 20mph for 350W and 23mph for 500W bikes. So the bikes are not particularly powerful. Type approval would not be required. Users still need to be registered...

no, I don't mean stick to 250W. The BBSHD isn't 250W labelled anyway. If you build anything with more than 48V (13S), you need to take a lot more precautions for your own safety beside space for a number plate and lighting. There is an interesting article about Belgium 'Moped Class P'...

don't go there. You want to build an electric motorbike, you need to start with a bike that is suitable for future type approval. Check the specs of GreyP bikes, they went through type approval: suspension, dual circuit hydraulics, indicators, kickstand, number plate, lighting etc.

more testing. The Chinese developed a blood test for specific antibody and two specific corvid genes that gives them accurate knowledge of who's got the infection and which stage they are in, thus they know how effective their isolation measures are. We wait for people who are either having...

an e-bike similar to your FX2? I would recommend the Woosh Faro: hydraulic brakes, 5 assist levels, 36V * 8AH hidden battery (288WH) or 17AH downtube battery. https;//wooshbikes.co.uk/?faro

why would you want Boris to spend money on people who are going to die anyway?

I went to an exhibition for that type of equipment in their early days, still remember how fascinated I was watching the pick and place machines. Most stands were showing German, Japanese and Korean machines. I knew then that we've lost the chance building computers here after the euphoria of...

it's in stock, £299 including courier cost.

I remember the time when I tried to teach my children how to solder and how disinterested they were. On the other hand, I taught my son how to program in VB and Miscrosoft access database, he picked that up right away. My daughter showed zero interest.

the will of the people who voted for tories last December.

that's one of the things that should be taught to youngsters! they may learn how to generate a negative voltage from a single battery source.

I don't know the brand of the bike but the battery is called 'small frog'. I have it in 36V 13AH. https:/wooshbikes.co.uk/?batteries#smallfrog

battery prices will come down like in this graph (take it with a suitable pinch of salt, but the rough shape is ok): Price in US$, per kWH for e-cars. The leap (2014-2015) is when Li-S batteries replace Li-Ion in extended batteries. When that happens, you'd be mad to buy a new car with IC motor.

simpler installation, a bit less wires to hide, better weight distribution, better centre of gravity. You will have to remove your beautiful Tigra crankset, but keep the rear 9-speed cassette. The TSDZ2 comes with 42T single chainring and new cranks, will accept another smaller BCD 110mm 34T...

TSDZ2 with 48V 12AH downtube battery (576WH against the Pro's 375WH ). longer range, higher torque and cheaper too. https://wooshbikes.co.uk/cart/#/product/uid-207-tsdz2-12ah/tsdz2-cd-kit-48v-12ah

they've been doing research work on Li-S batteries since 1960s. Li-S batteries for cars are nearly ready, still have to wait for possibly 5-10 more years. For bikes, a bit longer. but that's the direction of progress. from wiki: As of 2015 few companies had been able to commercialize the...

not at the moment.

To zero the trip meter: toggle the distance display to TRIP counter then hold down both the top and bottom buttons for 2 seconds. Be careful, if you hold down just the bottom button, the bike will be put into walk mode. So Squeeze the brakes just in case. A short manual on the KM 529 LCD is on...

they discharge it at 0.5C. Pretty useable for e-bikes. PS: 99% retention: that seems a bid dodgy. They use some formula that I have not looked at. Here are the test charts:

who is going to do that? not another newspaper. Twitter don't get to the newsstand.
