    Electrical Ground

    Afraid that is the fantasy going back to Westinghouse and Edison. The voltage does go through 0 v but it is back up to lethal levels much quicker than nerves or muscles can respond. A full cycle at 50 Hz is 20mS , a half cycle 10mS , and significant voltage from 1mS from crossover. To...

    Electrical Ground

    It wasn't a direct connection then.. 230v accros the body , driving say 100 ma will cause all the muscle groups it contacts to contract violently. If a live wire is grasped by the hand, the contraction makes it impossible for the person to let go..if it were on the back of the hand, it would...

    Brexit, for once some facts.

    T.May is perfectly correct in that there will be a difference between EU citizens coming to the UK before and after the transition. But not in a good way. Why would self respecting EU citizens, whose rights are respected in 27 countries choose to go to another country, where it is starkly...

    Electrical Ground

    Not really so.. The arguement about carbon fibre is correct of course but I don't think that weighted much ( pun intended ) on the thnking of early electric bike designers. The aluminium would be ok for conductive purposes, it's not bad compared with copper only 30% worse. The problem is that...

    Need help choosing a bike for 19 mile commute

    I think you are being a little disingenuous, just a little. With derestriction, the motor is working harder. That means it will heat up more.. probably not a problem, but the mechanical parts, the reduction gears, the pawls, the washers and the bearings are now getting more revolutions for...
