I have not done any forensic checks until now so I don't know the answer.

As far as I know, they don't lock the controller but you would void the guarantee if you reprogram it. I ordered 14A 48V controllers for them from Bafang to suit my 48V 10AH bag batteries. The 36V BBS01 has 36V 15A controller to suit my 36V 15AH bag batteries.

scientists at US NIF will announce tomorrow that they put 2.1 megajoules in and got 2.5 megajoules out. So far so good. However, it costs them tens of millions $ to produce a single shot. Still, future prospects look pretty good. Essentially, 3MJ of laser being fired at the capsule, but only...

I used to be sceptical about nuclear power. This one (TMSR-LF1) seems better than most.

If you need more range, ask for 12AH battery.

thank you. I should go get my eyes tested at specsavers! @Teal3, you can top up.

we take Halfords vouchers. Please email support@wooshbikes.co.uk or visit https://wooshbikes.co.uk/?cycletowork The process is fairly straightforward. You choose a bike like the Woosh Camino then let us know. I email you a quotation. You apply for the voucher. When the voucher arrives, you let...

what do you think of Starmer's plan for constitutional reforms?

I thought I could keep it quiet! What was I thinking??

Johnson's time has passed, he knows that by the number of MPs supporting his candidacy (102). Sunak helps the tories reduce the deficit but that won't be enough to beat Starmer who is steering Labour to victory.

Johnson could have made some kind of a comeback when he collected more support than Mordaunt last month. Could you think of any reason why he pulled out of the vote for PM?

Bbc2 last night screened a program called the secret genius of modern life, featuring essentially the role of electric vehicles. One of them is solar powered. Their promoters claimed that the solar cells on this car can collect enough for 11,000 miles a year. I can see people may be interested...

Nuclear fusion is making good progress at the moment. Especially in China.

If you are concerned with how your tax is going to be spent, you would not vote for someone like BJ. Sunak is the right PM for the moment. Before him, johnson brought the Pound down to 1.18usd, Truss brought the pound to 1.14usd. Sunak got it back up to 1.21. The market has a way to judge...

Johnson is economically incompetent, a proven liar and permanently lazy. Truss is clumsy but at least, she called a spade a spade when she fell out with Braverman. Sunak is not only more intelligent and quicker than Johnson, he is more likely to limit the damage to our economy. Time for the...

the C691 LCD has similar facilities, LCD brightness, number of assist levels, wheel diameter, speed limit, units etc are all there. Other engineering parameters like number of magnets on the pedal sensor etc can't or shouldn't be changed are suitably programmed in the BBS01 controller.

I mean the hub motors lose rapidly its efficiency and consequently its torque when its rotational speed drops below around 80rpm. This is the common situation when you climb a steep hill. If you have a crank drive, you can use your gears to adapt the motor to the gradient so to increase the...

That's correct. You don't have to plug the throttle in, but if you buy the non throttle model, you can't add the throttle later.

Hub drives do not stress the chain but crank drives are much better at low speed (less than 10mph), especially if your tricycle does not have a rear differential which helps keep the tricycle stable when cornering. Crank drives don't loose torque at low speed like hub drives, you retain full...

it's up to the individuals to put their bikes through SVA, the main thing is to make sure that the kit will pass if the customers choose to do that.
