I feel rather lucky that my Magic Pie skimmed through customs with no duty.

That would be very helpful, could you PM me? Cheers.

Clearly these batteries are getting better then. I'm just used to so many laptop/phone batteries having very disappointing performance in almost no time after daily use of the battery. Although, I suppose it is true that with a laptop battery, there is either enough V to run the laptop or...

Ah!! I see. Superb. Assuming I break down in tears trying to build one myself, I will definitely use them.

Thanks, I'm almost considering it, just to see if the old duffer who owned one of the bike shops I tried was telling the truth when he suggested it was a herculean task I was asking for. Amusingly he said "And I suppose it's CHINESE!?" and when I said yes, he waved his hand a me dismissively...

Is that used 5-6 days a week, all year round for 2 years though? I suppose one advantage of a tailing off battery is that your muscles take up some of the slack and you end up getting gradually fitter :)

I saw lithium-ion batteries being made once, looked complex, and expensive. I've never "got on" with Lithium. Finicky to charge, store, and despite these new all singing/dancing LifePO things, I think I'll watch on the sidelines and see how they turn out. Overall, they have always struck...

So I took my Magic Pie to 3 different bike shops and they all looked at me like a space alien. Even the concept of electric bikes seemed strange to them. One though I meant an electric moped and said I should go to a motorbike shop. I don't have an SJS cycles near me, I'm in Manchester...

The problem with these bikes is that they attract unwanted attention towards e-bikes as a whole. They make it more likely for the police to stop people using higher powered, but sensibly ridden bikes.

Hi Gents and Ladies, So finally my batteries arrived, I have my hub motor, now I'm really wondering what bike I should use. First things first, my ex-mrs has a very shabby bike she's letting me have to experiment on...but after that, I wondered what recommendations people have as I don't...

Clearly this is a dug up thread, but I think the future for the e-bike is in lightweight, small assist bikes. Something like 125W, that just makes a bike that looks, feels and handles almost identical to any other pedal bike that bit easier to cycle up hills. The 1000W, large AH toys we have...

The instantaneous current (for very short intervals) many batteries can provide is really rather spectacular. Take a 40AH 12V car battery for example, most can do say 400 cold cranking amps, which is to say it can supply 400A for 30s at -18C! In a short, at normal temperature, the instaneous...

You're not missing anything. I guess I was just thinking aloud. Clearly it works for cars, but then they are routing a LOT more connections. If I added extra electrical items, I though it would be nice to just use the positive wire and tap the ground of the frame. But you're right, it's...

That's reassuring, I suppose it's just suck it and see. Being a front hub motor, that at least balances some weight forward. The batteries were at least cheap, less than £90 delivered (when they eventually arrive), yet seem quite high quality in terms of cycle life.

Obviously I haven't had enough experience with mine yet to know if it is any good. They are made by Golden Motor (www.goldenmotor.com). Some problems I've heard of with them are that the owner of the company is a little arrogant, which may or may not be true, I think perhaps he's just someone...

Half a spanner and a jubilee clip sound quite agreeable actually. Regarding the spoking, I suspect i'm best off leaving that to the professionals :) Thanks for the link though.

I was more thinking of just saving a bit of wire between the front and back of the bike, but not necessarily having the ground connection at the fork, the negative wire could connect to the top of the frame. Advice taken on board though. Regarding the voltage, my understanding of the magic...

Thanks for the warm welcome NRG! Yep, I have worried that I have gone overboard on the batteries and weight... I chose the Magic Pie because it just seemed a good deal for a beginner, what with the controller integrated into the hub, and a flexible voltage and power output range. It...

While I'm very impressed with the engineering going on here, I was planning to use the head of a 98LED torch I got from ASDA on offer for £7 which takes 4.5V at about 2A. I'm going to power the head with a 4.8V NimH pack. Still much kudos to the cool tinkering going on here!

Hi all, and hello. I'm new to electric bikes, and I don't even have a bike yet. I've just received a Golden Motor Magic Pie I ordered, and I have 4 11Ah Haze Gel Cells (lead acid) on order. I'd planned to keep these in panniers maybe? Now I have my motor, I plan to get it spoked into a...
