Absolutely Rog, that is what makes it so interesting, an art rather than a science. I think most of us try to be all things to all men when we should probably be specialising at one end of the scale or the other, the super light bike with a little extra boost or a virtual moped. There is...

It so depends on the use and assist setting Bruce, our top level of assist is very powerful and produces a lot of torque. Hence the 6 levels of assistance on the Alpino bikes. We have achieved figures of 6 and 7Wh/m and I know we can improve massively on that, however what's the point...

Wow! That is huge Flecc, though I think I can guess the bike! All the best David

We do Bruce, we work directly with the battery manufacturers' laboratories. These guys are brilliant and as you can imagine have some of the best test equipment in the world. They are particularly interested in electric bicycles and other electric vehicles. On of my Wisper technicians sits on a...

Thanks for the clarification Leonard. Although we are not subject to such rules on Pedelec, the majority of contributors with a comercial interest conform to the ethos you advocate. This particular thread was unusual as can be seen by my comments on the opening post. There were already two...

Hi David, It is nice to see the spring flowers popping up everywhere, but it comes at a cost..... I had to cut the grass at the weekend! :o All the best David

Great news Tom! Thanks for the business, enjoy your Wisper. All the best David

Hi David and thanks Tony. The control system on our Dapu driven bikes (906, 706,806) is quite sophisticated. As Flecc quite correctly says, the controller is set to cut power to the motor when it reaches 31.5V to stop the possibility of any damage to the cells. When this happens you will...

Hi Shoe I am afraid the £850.00 was plus VAT good ol' Customs and Excise get £170.00, and we have already paid 6% duty! :eek: Making the retail price at least £1,020.00 (I wish we made such a good profit!) All the best David

Hi Rog, In the early days we could only afford this kind of case, they are cheap and can be made to any size simply by increasing the length of the aluminium extrusion. However they tend to be easily broken, can let in water and of course it's not a great idea to use such a good conductor as...

Yep, it's a Wisper but quite an old model. If the battery has been left flat for 4 years or so it will not hold much of a charge. I am not sure whether we have any of these batteries in stock at the moment so it may take a couple of months to get one. Best check with Steve in support before...

Thanks Frank, it's also a great place for competitors to meet and chat. :D Keep up the posts I for one read them with interest! All the best David

Hi Steve, we will be retailing at about £1,050.00. DaaHub is just a fun name, nothing more. Of course we can use the name in many derivations, DaaBag, DaaRack etc. It was also "clean" as far as the Google search engine was concerned. Thanks for asking. :) All the best David

Hi Leonard, I absolutely understand your point and it is well made, please allow me to explain. Of course I am interested in selling bikes but that is not my prime reason for posting here. I do talk about new Wisper products however I try to do this within an existing post that has already...

Hi DayGlow A quick point about the Oxygen, they are a good bike but have nothing to do with Wisper. Despite the similar looks most of the components are different including the battery and they are made in different factories. I understand your confusion they do look similar which I think...

That's huge Matt, well done sir! Regards David

Riding through Laos Here is the latest instalment of Guim's adventure on his Wisper. Pedaling Laos on Vimeo Regards David

Ahh that'll be it Tony, I can't wait to see what happens if we get the Li S batteries going! All the best David

It seems we have another Guru! Thanks Ed as always for explaining. All the best D :)

Interesting Ed, I wonder what caused the huge peak in 2008? Was that when petrol went through the £1.00/l barrier? In general only a small increase over the years, rather disappointing..... Regards David
