Seriously Andrew I would be delighted, I will have the sample here in mid September after we have given it a bashing in New Zealand. If you like it I will give you our suppliers details. It'll cost you a pint though! All the best David

Yes I was amazed too, I did actually mean Andrew (Mussels) but you would be most welcome. :D I would also be pleased to introduce you to the supplier. All the best David

Good point Andrew and something we looked into, however it does make the batteries very much more expensive and technically it doesn't work too well. All the best David

Good points Final samples have just arrived at the factory in our standard 14Ah Li Po case, the difference in weight of the very latest LiFePo4 batteries is not as high as we had anticipated, the existing Li Po 14Ah pack weighs 4.1Kg the new 14Ah LiFePO4 is only .5kg heavier at 4.6Kg...

There's the rub, we have a choice of 14A LiFePO4 or 16A Li Ion in our larger case, the 14A LifePO4 weighs just under 1KG more than the 16A Li Ion. To make the choice even more (or less) complicated we can offer a 3 year guarantee on the LiFePO4. :confused: My feeling is we offer a limited...

Skype Hi Bill My Skype is simply david.miall Best regards David

Yes, I had the wrong impression completely! :o I understand now. :) All the best David

No problem, please keep me in the loop! Best regards David

Sorry Andrew, got carried away with the subject matter! :o Best regards David

Hi Allen All very strange, it may be something as simple as the 5th LED is not connecting or is a duff one. What voltage are you getting from the battery when fully charged? Are all the lights on the bike handlebars lit? Regards David

Hi Basil Is your bike a Wisper? Best regards David

Thanks Hugo for your kind comments! Please let me know how you get on? Best regards David

Hi Flecc We are finding the discharge rate on this batch of test LiFePO4 batteries is actually higher than the Li Ion we are currently using, the charge time is also reduced. All the best David

Flecc's points are as always spot on. With the Panasonic unit as soon as you stop putting pressure on the pedals the power stops so would be completely useless for someone with one leg. However the safety feature is exactly that, as soon as you stop pedalling the motor cuts. Most speed sensor...

Cost Hi Mike As we are now buying 1000's of batteries at a time, due to economies of scale, we will be able to keep the cost the same as the current 14A Li Po. There is a possibility we could even reduce the price. :) All the best David

The higher power battery at this level will really only add range and will extend the sweet spot on the battery so a rider can complete more miles at maximum power. My feeling currently is to go for the LiFePo4 or maybe offer a choice. All the best David

Thanks SL, this is exactly why the throttle is there, far better to choose your own level of assistance than let a torque sensor do it for you, a torque sensor cannot calculate a riders level of fitness, hence the reason we have steered clear. The throttle assist is more simple and can be...

Hi Allen The reason the half turn is needed before the motor starts is for two reasons, firstly is saves a massive amount of power and gives you better range in stop start journeys and secondly is for safety reasons so the bike does not scoot off as soon as you put pressure on the pedals...

I need your help! Buying the best battery available is a constantly moving target! We have employed a full time electronics engineer based in Shanghai to help with the quest to find the best e-bike battery, and our new 2011 bikes will come with standard 11 or 16A batteries. Rather than the...

Hi Killjoy Sorry to read about your problem and thanks so much to everyone else for your help! :) Been a bit busy over the last few weeks getting the 2011 bikes and Daahub kit ready for Eurobike, so have not been onto Pedelecs much. Unless you understand electronics KJ it really is...
