    Brexit, for once some facts.

    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...

    Brexit, for once some facts.

    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...

    E tricycle advise needed please.

    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.

    E tricycle advise needed please.

    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...

    48V BBS01 250W is now in stock

    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.

    E tricycle advise needed please.

    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...

    Hemp Batteries are Eight Times More Powerful than Lithium, Scientists Discover

    Plenty of smoke. Their gravimetric density is typically 40wh per kg, pretty useless really. The hemp is just a clickbait. The hemp is cooked at high temperature to get rid of all other chemicals leaving just carbon in a process similar to making coke for steel. The carbon is then used to make...

    Carrera Vengance Speed Hack.

    I don't think it's easy or even possible. you need to assess first whether there is a speed sensor on your bike or inside the motor. Then you have to access the speed sensor wire if there is one.

    Sprocket wear

    although I agree that the torque from the motor is relatively moderate, the wear still accumulates with mileage. Riders with a crank drive also rarely have to stand on the pedals. The chain and the small cogs at the rear suffer much more wear and tear with a crank drive motor compared to a hub...

    Brexit, for once some facts.

    The last time I was at A&E which is about this time last year, I waited already more than 12 hours for treatment. They have a conveyor belt system, if your treatment is uncomplicated, you will be seen by a triage nurse, a junior doctor then a consultant. Each stage takes a minimum of 3 hours...

    my office building is instituting a ban on lithium-ion cell e-bikes. what options do i have?

    there isn't any other battery option for bikes and kits outside Lithium batteries. I can understand their motivation to ban all the e-scooters but it is rather a silly blanket ban on all things with Lithium batteries because it excludes all street legal bikes which should not impact on their...

    Prices of the electricity we use to charge

    keep the same units and replace 80% with 0.8 to avoid confusion. 64p/kwh * 5.5kwh / 0.8 = 440p Replace 625wh with 0.625kwh for the same reason (units). 64p/kwh * 0.625kwh / 0.8 = 50p
