    News: Dutch e-bike sales increase by a quarter

    No, but they do have the pleasure of the power against the fierce headwinds on the polders, something all very flat areas suffer. Ask the cyclists in our Eastern counties. .

    I wonder why..

    Maybe, but even on bridle paths I don't want suspension. I haven't had any suspension all my cycling life and don't like it on bikes I've tried with it. I'd always rather save the weight. .

    I wonder why..

    Because that's what the majority of customers want. For example, I would never consider rear suspension and for road use don't want front suspension either. Many items in your wish list would be part of my hate list, something true for many others too. .

    I own a Nissan Leaf ev, and considering an electric bike

    In effect they do to a limited extent Trex, since the rental figure is based on the expected mileage. The Leaf monthly rental scale is from 7000 miles to 12000 miles per annum and agreement rental periods are from 12 to 84 months. For the Nissan Leaf the monthly cost scale is from £70 to £113...

    I own a Nissan Leaf ev, and considering an electric bike

    They have to be kept for life or at least a decade. Their intrinsic problem which the trade cannot solve is that, like e-bikes, the battery forms such a large part of the vehicle cost. So when selling second hand, any buyer considers the possiblity that they may have soon to fork out many...

    This experience is not uncommon, their inconsistency often reported and it's not necessarily in the order you've experienced. Sometimes the sales experience falls short but after sales service extraordinarily good, and I've experienced this myself. It seems in the lap of the gods which one...

    Buying a ebike part 2

    This is normal since these meters work on the tiny decline in voltage and the initial rate of decline from full can be rapid. It's why the road distance per bar of decline often isn't consistent even when the terrain is. .

    Nominal Power misunderstood?

    Here's a journey graph of the second series Panasonic unit from 2007 when the unit was well below Bosch and Impulse power levels. It can be seen that it almost reached 500 watts at times and routinely to 400 watts. From this graph you can see that this relatively low powered unit averages 250...

    Ebike battery alternative

    This does sound like a phase not firing, very apparent when under load. Have you measured for continuity between all the pairings of the three phase wires? However check out Alan's suggestion since you have SLAs. The only suggestion I can give for separating the motor side plate is to remove...

    Nominal Power misunderstood?

    It used to be the point of CD, especially in the early strict 200 watt days, but more recently they've got into a power race. To give some idea of the situation, back in 2001 Panasonic's new CD unit was a true 250 watt one, not very powerful by today's standards and with an increasing power...

    Ebike battery alternative

    A faulty end of life battery wil not cause juddering, only the cutting out under high load. Juddering is usually due to erratic phase firing which can happen with a faulty connection or possibly an internal fault in one of the motor phase windings. Can you check for continuity around the three...

    I own a Nissan Leaf ev, and considering an electric bike

    As we expected, that £10444 2015 Leaf Acenta with owned battery and home charger sold at the weekend, just one clear day after going on sale. Must be one of the fastest ever Leaf sales! .

    Ebike battery alternative

    No, definitely not a broken fuse. Carefully check the three wire connections at all points from motor to controller, since a faulty connection in any of those can cause exactly that juddering. .

    Ebike battery alternative

    The 576 watts is consumption not power, and no motor is 100% efficient so the net maximum power is probably nearer 400 watts and that only available within part of the revs. range. Sakura's two wire brush motors were always rated as 200 watt nominal to comply with the law at the time of supply...

    Avast antivirus flagged up a threat warning

    Ignore it, Avast like some other anti-virus software uses heuristics as well as actual data lists of viruses. That's a system by which anything that looks like it might be a virus is reported as suspect. This can create many false alarms. In Avast I believe you can set the sensitivity level...

    Nominal Power misunderstood?

    Let me put a few things straight Flud. First you greatly underrate rider power, an averagely fit rider can maintain a steady 200 watts, the third of 250 watts you suggest is quite puny at 83 watts. We consume 50 watts just sitting still in an armchair. The 330 watts that you suggest is...

    Nominal Power misunderstood?

    Amongst other things it means I know the law which you very clearly do not. You've taken one aspect of the EAPC law and an engineering reading of power output and had the nerve to lecture those who know far more than you on the subject. Pedelec law exists in four parts of different laws. In...

    Nominal Power misunderstood?

    Being ex trade, having over 65 years experience and knowledge of powered bicycles and following the development of the laws over all those years, I feel more able to talk sense than you on the subject. Of course I fully understand that at double the legal rated output a battery could not last...

    Nominal Power misunderstood?

    There are two problems with determining motor wattage on e-bikes. First is that measuring the motor shaft output is impossible on most without taking the units to pieces and measuring only the motor part. Arguably and correctly, that alters the unit's output so the finding is incorrect for the...
