Birkenhead Cycles are dealers of Wisper Bikes covering Liverpool & the Wirral. We recently purchased two 806 step through folding bikes from them and after a day or so we noticed a small problem with one of them. This turned out not to be their fault but nevertheless the way they resolved the...

I went to see a 806 bike at a Wisper dealer yesterday and it had mechanical disk brakes yet when I checked the online manual the specs said they were hydraulic - anyone understand the reason for this anomaly ? I also wonder which would be better for us. I have hydraulic brakes on my full size...

That just confirms all my prejudice against the H company. Before deciding to do my own conversion and discovering Woosh I booked a test ride at my local store on that bike. I thought it quite a professional service and when I went to get it i asked what I thought was the honest bike dept...

Thanks Robert. I have since looked at the site again and I was being over cautious and I am sure the chargers would be suitable if I specify the lead acid option. It was all the references to the lithium ion chemistry that put me off. They make the chargers sold by that well known multiple car...

Off topic and possibly stupid post but just want to be certain. The prices on the above site look very reasonable. Many of the chargers say they are suitable for lead acid batteries so would this one for example be suitable for charging a 12v conventional lead acid leisure battery (these are not...

As soon as I decided to get an e-bike my instinct was to go for as much power as possible and stuff the law. For one reason and another I have ended up legal but have to admit am well satisfied with it. Am sure it depends largely where you live but if there are any more fatalities and...

I am not qualified to reply really as I have only done one conversion but I thought exactly the same as you initially. I ended up buying a similar specced bike to the Subway 2 but was convinced to go for rear wheel drive. My view now is that it is only 250w but can go up hills easily (but I am...

Apologies to the o/p for jumping in on his thread but when you say you are 'spinning out' does that mean you are going too fast for your legs to contribute any power as the pedals are going round so fast ? This occurred to me a couple of weeks ago as even with my 250W motor at times it nearly...

I have sealed all my cable joints with self amalgamating tape. This is great stuff and if you put it on with just the right amount of pressure it sort of 'melts' and will make a completely waterproof seal. You can get it off but you are best using a Stanley knife and a lot of care ;). It is...

This depends on your personality - for me (a bit of an anorak) it is the exact opposite. I really enjoy and get a kick out of knowing what is going on with any tech product I use in my day to day life. I almost get as much pleasure in discovering how new things work as I do from using them...

Thanks Tony :) I was guilty when I started this thread of not googling for the answer first ! Now I have done I realise just how much info there is on this subject (including the amazing revelation that Tesla uses the same battery format that I have - if it is good enough for Elon it is good...

Thanks Neal The battery I have is "17AH HL downtube battery with Panasonic 18650-B cells". I have a multimeter so can determine overall voltage but how would I find out how many cells I have ? I assume there must be banks of cells in series to make up the 36V and these banks wired in parallel...

Thanks for the replies :) I presume that balancing must occur if you charge fully as you say as all the individual cells must become full. I am not sure though that by trying to keep the cells in the optimum window is overthinking it as the battery/s are the single biggest cost of my system. I...

How many here always charge their batteries fully every time they need a charge? As I understand it, batteries like to be kept in the 40-70% range of their capacity. I can understand that if you are a daily commuter user you have no choice other than recharge to full but for someone like me...

Going to put it on the rear disk lever then. Not only is my motor there but I always apply the rear brake instinctively just before the front having learnt the hard way what happens if you slam the front brake on when riding a racing bike when I was probably 14 or so. You only do it once ;)
