    On the boat Hi Guys Thanks for the support it really is appreciated. The rear sprockets range from 11 to 30 tooth and the drive-wheels are 50 and 34 We are only talking about the lowest gear on the 806 being of not much use but to get the rest of the range from very high to very low...

    250 or 500 Sorry for the misunderstanding guys. The 500W are for the US and Canadian market where all the Wispers carry the 500W motor 650W being the maximum allowed, the Police bikes for the UK and EU are all 250W. I do agree however that electric bikes of any power can be sold in EU...

    Thanks! :) Flecc you off course are absolutely right in the lowest gear my SFH legs were spinning so fast they were a blur just to get enough momentum to stop falling off. :) We will get rid. All the best David

    13 tooth Hi Flecc Thanks for that. The original spec was 50 12 but I will confirm tomorrow as we were having the odd problem, that is why we ended up using the chaindrive from a racing style bike. I always felt that electric bikes needed as big a chaindrive as possible and the smallest...

    Twin motors Hi Danny we did make a twin motored bike but the expense and complexity mad the new 500w Bafang a better option. So we now limit them to 250 or 500w rear hub motor. All the best David

    Boosting the top speed of a Wisper 905se Sport

    Dum cadence sensors Wisper bikes do not have any intelligence at all! :eek: There is simply a switch that is turned on when the pedals are being turned, this at the moment can be over ridden by using the throttle. After making a 905 that used the system are three main reasons why we...

    Tent Cot Hi Flecc Unfortunately we have had a falling out with Tent Cot after we held an exhibition for them at Olympia and their Australian rep was doing deals with my customers behind my back and the whole thing got out of hand, so I am afraid at the moment we are not represented in the...

    Motor Power Hi Flecc Nice to hear from you! Thanks for your comments, it is a pretty bike! The motor is the 250w Bafang as per all our range but as the bike will be used on shorter runs the battery is a 24V 9A on this first edition. The more expensive larger battery option may be...

    Boosting the top speed of a Wisper 905se Sport

    Speed Hi Gordon OK all seems to be fine, so if you could do the up and down the road test that would help me. We have just opened a new dealer in Ellon, not far from you so we will be able to sort it out quite easily if there is a problem. Did your bike come from E Bikes direct? I...

    Boosting the top speed of a Wisper 905se Sport

    Top speed Hi Gordon, you should be getting more than 15mph when de-restricted in perfect conditions of course and certainly your weight is not a problem. If your tyres are at 60psi, the road is flat (it is worth taking readings in both directions on the same piece of road) and metaled, there...

    Wisper 806fe Preview

    Hi Guys I thought some of you may be interested in a preview of the new Wisper 806fe. The wheel base is slightly longer than the old 805 and we have added a second drive wheel to give the bike 16 gears. Those who have tried it out say it is more like a road bike than a folder...

    Boosting the top speed of a Wisper 905se Sport

    Speed Hi Gordon Sorry to say that is about it. The gears in the motor are set up for maximum torque and a road limit of 15mph, so even when we derestric you can only get the maximum according to the gearing. The only thing you can do is replace the motor with the new Bafang 500w hub...

    Speed. Hi Gordon, have you checked tyre pressures recently? This will certainly help. I assume you are de restricted? (your bike I mean!!) All the best David
