    Presteigne 2011

    I am confused about this event. We have been resaonably successful so far this year and are meeting and talking to loads of people who have lectric bikes or are interested in them. Perhaps it is our geographical location (Southampton) but Tour de Presteigne has not even been mentioned. Sure...

    Noise of Hub Motors

    I get teased every time I open my mouth. :D . Truth is, you guys, when you actually do the efficiency analysis of the Bafung vs time in a real world test bed you do see a drop off in efficiency. It is not that the motor fails - just it become less efficient. This is not the case if you use...

    Noise of Hub Motors

    We have been recieving a range of comments about noise from hub motors. Our experience is the hardest wearing hub motors with laser cut hard nylon composite cogs ARE more noisy than the 8Fun (Bafung) motors from China which employ softer cast plastic cogs. When you open up an 8Fun on the test...

    SURVEY - Research Request

    I am trying to compile a set of Wh/mile consumption numbers. Not to play one manufacturer off against another; I am quite willing not to have brands or marques attached to the data. To produce a distribution, I am asking you to post the following data: Voltage of your battery (V) Ah of...

    Wisper rear Bafang and front Dapu motors.....

    Is it a trade secret or can you tell us how much you limit your amp draws on your batteries? I am going to start a thread (a sort of survey) telling people how to calculate their watt hourage on their batteries and to tell me what they consider to be their typical real world range and whether...

    Wisper rear Bafang and front Dapu motors.....

    David, this is really really really interesting. At Barcelona Tech I am involved in some loose supervision of a PhD project on battery wear and tear. We have designed (they have built) a simulator which enables us to put batteries through hours of simulated travel. This includes hill starts as...

    Cost of recharging a battery?

    I was asked the cost of recharging a 360Wh battery. Can I assume a charger is fairly efficient. Like, would it cost me 400Wh on my domestic electricity tariff to charge the battery? Thx Bruce

    Editorial Independence I am curious as to who "we" in the context of "we can publish the best, dump the rest and make something invaluable to potential electric bike buyers." EdBike, could you please tell us all who you are? You have not posted, as far as I can see, on the “Introduce...

    Test riding different ebikes.

    Never wanting to disagree with Flecc.... I think annual UK sales of reasonable quality (£800+) electric bikes is about 9,000 per year. 3 million UK bike sales in total. 1 in 7 bikes sold in Switzerland is electric. 1 in 12 in Germany....
