..... Is going faster not a change in behaviour?

... God bless your eyesight!

... That argument of true, within the motor itself,.. but ignores the effect on the system, all external wiring etc. , Where the wiring mass has to square to compensate for the additional losses

.. the Motus , which is the only modern bike i have experience of, has rim brakes with hydraulic cables( Tubes? ):. I find them excellent for road use. Firm responsive, . There will be those on this forum who suggest that unless you have disc brakes you are not at the races ... I would see...

Thanks for the link. I would be agreeing with the person called KS , Very simply if you need a fast rotation motor you need to use multiple parallel coils of low number of turns in order to minimise self induction and consequent back EMF. , The cost of this is very high copper losses as the...

.. you must be looking in the wrong place.. i take it that your overall voltage is 25 V .

Excellent photos. The black rectangles with 3 pins are the power transistors , used for the Bat management system. , Putting one lead of your dmm on voltage scale, to the negative terminals of the battery pack and the other lead to the same pin of each of these transistors in turn you...

Train ... Easier to do from central London than from central Dublin... But I do accept the point. Flight .. whether synthetic fuels e.g methanol, hydrogen burnt in turbines, is a better option than in electrical systems will probably play out over a much longer time scale, but we will still be...

.. yep..

..... Why not. This need not just be a pre April 1 story. Current battery technology has not the energy density of conventional fuels, but there are options on the horizon. Metal air cells , whereby a metal such as aluminium is allowed to react with caustic soda, and use oxigen from air ...

... The kindle 3g roaming operate in 100 countries including the Americas and Europe inc. Turkey. My point was not an advert for Amazon, but to indicate that an international company could provide at no cost to the Consumer a wide scale communications network, and this could be used for security.

... You won't get people on this forum tut tutting about a desire to use an ebike for a 10 mile journey. .. Leave that to the Lycra brigade. Travelling 10 miles regularly is highly feasible, will take the guts of 45 minutes or more, and you will know you have been excercised. It is also...

.. The prices being quoted are very very high. Value is in the eye of the beholder, and on a cost \ benefit analysis. As a utility vehicle it could not stack up as ebikes of good performance can be got at 1/4 the price, reliable ones at 1/3 and luxury models at 1/2 . As a luxury good and...

... No harm hoping , i suspect that the transition will be slower than that eg. 300 to 350. And 400 to 450 . 10% per year would be more likely.

... I can agree with you, there are only a few manufacturers of quality ebike motor systems and it would be very feasible to reduce the illicit second hand market for these. The battery packs, the display units and the motors are all serial numbered ... I was requested by Raliegh to provide...

... In theory yes . The starting motor in a domestic car might be drawing 3000w for the duration . Such a motor will be drawing 300amps!, So will deplete the battery quickly. It would also burn out if kept on for any length of time. Look at the thickness of the cables going from the battery to...

.... Delicate in this context has a number of meanings....

Design sequence. 1. Expected speed ... S. In M sec. Pi x D x R 2. Intended wheel diameter D in metres 3. Revs of wheel R per second 4. Power required ... Needs estimates of weight and cross sectional area of vehicle.. no simple formula here. Let's say you decide on 3000w...

.... Not having personal experience of them,in recent years, but common sense would suggest. 1 they will be more comfortable and potentially more stable as there is more material in contact with the road and there is more suspension There is a suggestion that they have more puncture tolerance...

.. well spring has officially come now we at at the equinox, so plenty of more days to enjoy being out..
