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...

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...

I have recently completed the conversion of my hybrid bike to electric power using a rear wheel motor. This bike has front suspension, rack and panniers and virtually every other bike gadget going (including tinkling bell for pedestrians and a siren for cars !). Pic to be posted later. The end...

I have recently put a rear wheel with a hub motor on my brand new hybrid bike (see another thread). Unfortunately the wheel does not match the front one cosmetically so I have come up with an idea which I would appreciate some feedback on please. I now have a 250W motor but quite fancy a 350W...

Apologies as this thread is not strictly related to electric bikes other than it concerns my bike which is electric. I have a Cannondale hybrid bike which I have put a motorised rear hub on. I am looking for puncture options so have recently bought a spare inner tube to carry around with me...

As mentioned on another thread I have just installed a rear hub kit. How do people waterproof their wiring - are the plugs themselves good enough or should I use some self amalgamating tape ? In fact, is it wise to avoid using the power during heavy rain and just rely on human power ?

I have just installed my first kit and now want to know how best to monitor my battery usage. At the moment I have a J-LCD King meter which has a crude 5 segment scale showing charge left. The battery I have is a load of Panasonic 18650 B cells making up 17Ah 36V. These are packed into a Shansan...

Hi all I thought I would share my experience of adding electric power to a new bike and what I have learned in case there are any newbies like me who are trying to decide whether to DIY or buy a ready built off the shelf bike I have wanted an electric bike ever since I owned an electric moped...

Hi I am about to install a 250W rear hub motor on a hybrid bike. I am used to a lightweight road bike and although this bike is supposed to be light at 12kg it feels like quite a lump to me especially as I have fitted mudguards and a rack. I am a bit concerned that I might not have enough...

Hi Am trying to decide which donor bike to buy to fit a powered rear hub onto. Here is my dilemma - I am very weird shape ! Around 3 years ago I had a series of fractures in my back which has left my torso very much shorter. Before this all happened I was just under 6' but am now just over 5'...

Hi all I was going to buy a new bike and e-bike kit and install it myself. However I am a bit uncertain whether I have the necessary skill despite having built my first push bike when I was 14 (some 40 years ago !). So now I am looking for some help - does anyone know of any firms or...

I am a 61 year old male with osteoporosis which has caused spinal fractures so am looking for an e-bike to give me some more independence. Up to 12 hours ago I was going to buy a Whoosh Kreiger having decided that I definitely want crank drive. However I saw my surgeon yesterday and he...
