    Battery and Motor Advances from Taiwan

    The motor sounds interesting. Do you think there is anything revolutionary regarding the battery?

    How to fool Kalkhoff engine...

    It would appear that there is now a 35 tooth chain wheel. A member reports having his new Agattu supplied with one.

    How to fool Kalkhoff engine...

    The thread titled busetti-ebay-60-mile-range has an explanation from about page 2 onwards.

    A Busetti On Ebay 60 Mile Range

    My bike is a 2008 Pro Connect. The one tooth extra on the rear sprocket won't make a massive difference and may very well suit you better.

    A Busetti On Ebay 60 Mile Range

    If the motor sprocket and rear wheel sprocket remain the same, then the road speed at which the motor cuts out will be fixed. Altering the chain ring size will have no affect on motor cut off road speed. As you say, the chain ring just has an influence on pedal cadence alone. Incidentally, I...

    Schwalbe Marathon

    Personally, I would have spent that little bit extra and gone for the Marathon Plus with Smartguard. I've done about 6000 miles on these without a puncture. Admittedly, it all been on road. I've heard that the Marathon Plus can be difficult to fit, but my set went on using just fingers and...

    A Busetti On Ebay 60 Mile Range

    I don't believe that cut off speed is affected by the chain ring size. My understanding is that the motor sprocket and hence the angular velocity of the motor shaft is what determines the cut off. Increasing the size of the motor sprocket will therefore increase both the cut off speed of the...

    A Busetti On Ebay 60 Mile Range

    Why would they do that? Reduce the size of the chain ring I mean. I would have thought that a smaller motor sprocket (less teeth) would be more susceptible to wear.

    Battery novice

    To avoid confusion, Rosie's bike has a Li based battery (I looked it up on the website), so frequent charging as originally indicated should not present a problem.

    panasonic 18ah battery.

    I believe that the BMS on our Panasonic batteries prevents them from being charged to 100% if their theoretical true capacity, or to be discharged to 0% for the very reasons outlined in your post. Because, unlike cars, our batteries need to be small and light weight, there isn't the luxury to...

    panasonic 18ah battery.

    When I buy my 18 Ah battery, I will be only be pleased if it accepts 1100 charge cycles or still has 60% of it's capacity (that is performs better than a new 10 Ah Panasonic battery) after 5 years. That is what is being claimed by the supplier / manufacturer, so am I being unreasonable by...

    Recommended: power your lights using DC-DC step down transformer

    Thanks for the links chaps. It was the battery connections that were of slight concern. I should have thought of flecc's pages and sipped from the font of knowledge.

    panasonic 18ah battery.

    I don't think it is available in the UK yet. 50 Cycles web site states Spring 2011. As far as the claims of extended life are concerned, I am sceptical. The original Panasonic battery fell well short of the claimed life. I have not seen any indication of an enhancement to the guarantee to...

    Recommended: power your lights using DC-DC step down transformer

    I'm really interested in this and it is something that I have been considering for a while. Any details about the transformer and pictures of the connections to the battery connector would be appreciated.

    Agattu Endurance II

    Sorry to hear of the death of your Agattu. The motor sprocket fault sounds very worrying. I have just checked mine and all seems to be ok. In contrast, my Pro Connect, which is probably of similar age to your Agattu is, mechanically, still going strong. It has done well over 7000 miles now...

    Ordering new Kalkhoff AGATTU XXL C8 (2011)?

    I have a 2008 Pro Connect which is fitted with the same 250 Watt motor and 8 speed gear combination as your Aggatu. Hill climbing ability is not an issue and is not compromised to any great extent by the 50 Watt differential between my unit and the 300 Watt motor. Because the motor drives...

    Gocycle...too flash??

    As an alternative to painting you could consider having a professional vinyl wrap. When you tire of it or want to sell, just take it off.

    Gocycle...too flash??

    It's not my thing, but I can see why some people would be attracted to it. The Go-Cycle has certainly raised the profile of electrically assisted bike and it has found its way into John Lewis stores. If John Lewis' buyers can see a market for it, I'm not going to argue that no one would want it.

    Optobike 600T test ride

    Moped design has really come on leaps and bounds and some of the examples posted above are testament to this. They really are sporty looking mopeds. Very trendy. Does anyone know how much it costs to get such mopeds through the SVA? Or how much the annual insurance premium is? I expect the...

    Battery novice

    If you do a very short runs out 3 or 4 miles, I would only charge every other outing. If you do longer runs 10 miles plus, it might be worth charging every time. It's difficult to put an exact figure on it due to there being so many variable factors. If the battery is new, it will benefit...
