There is a manufacturing batch code on the battery. My two faulty batteries were from different batches, so the long odds apply. I did buy a lottery ticket last Saturday as you suggested and this was the first one for many years. I lost. Is this a good or a bad thing? ps You owe me a...

Hello Styx. Just out of curiosity, have you posted something about your battery on the 50cycles forum? There was a short thread running on there about a battery but the thread has either been removed or I am being a dumbo. I can't find it anymore and I can't remember the name of the...

Well I’m back on the road again less than 24 hours after informing 50C of the problems that I have been experiencing. It is a little frustrating, but these things happen from time to time and I think that I have just been a little unlucky with this bike. Hopefully it has been remedied this time...

:D He seems harmless enough if not a little eccentric. From some of the posts that he has made, he is obviously delighted with his bike and getting a lot of enjoyment from it which is no bad thing. It is a bit of a niggle though when all the threads that you are interested in have been...

Well I'm off to 50C tomorrow to pick up battery number 3. They were very obliging and offered a replacement, again without hesitation. They also reiterated that out of the vast number sold globally and in the UK, the problems reported were minimal. I must just be really really really...

Thanks for the reassurance Flecc. I know these batteries are used in a growing number of applications so I am clinging to the notion that if they were no good, their usage would be shrinking not growing. I am just really disheartened that this new battery has failed in exactly the same manner as...

Oh **. My second battery is on the way out. I religiously ride the same route to and from work every day. My first battery lost over 20% of its capacity in fewer than four months of usage and was replaced under warranty by 50 Cycles without any problems. The bike (a Pro C) is now just under...

50% range reduction sounds quite a lot for the temperatures that you have stated. I have been riding in temperatures similar to those for the past week and although the range is reduced it is by far less than you are experiencing. Have you tried doing the battery self diagnostic check? This...

Thanks for pointing me in the direction of the forum James. That will be worth a look. Hopefully this will be a very occasional problem because I don’t fancy stripping the hub down. I always end up with a few spare springs and washers when I dismantle anything like that!

Since I have been riding an ebike, I have found that, in general, vehicle drivers tend to move out into the centre of the road and give me a safe gap, but an alarming number then pull back in before they have cleared me. I can only think that this happens because I am travelling faster than they...

No problems at all this morning (-1 deg) This is certainly a cold weather thing and -3 deg or below seems to be the temperature where the problems start. It's a bit of an irritation when it is stuck in a high gear, particularly when going up a few of the climbs that I encounter. I think I'll...

It all seems to point to the cold weather and the thickening of the lubricant. Although I have done 1400 miles now so I would have thought that things may be starting to free up. The bike has been inside a heated hangar for 10 hours today and I did a couple of laps indoors before setting off...

Pro Connect gears sticking. On the way to work this morning, after about 5 miles, (-4.7 deg C) I found that I could not select a gear lower than 5th. The change cable went slack as I changed to a gear lower than 5th. When I arrived at work, I examined the mechanism on the rear hub and...

Well I only have the Pro Connect, Agattu and the awful Giant Twist 2.0 to make my assessment on because these are the only ebikes that i have ridden. So by now you know it is going to be a Kalkhoff that gets my vote. I own a Pro Connect, but will give my vote to the Agattu. That doesn’t mean...

Thank you for taking the trouble to post the information Flecc. I was wiping down the motor casing and noticed that the centre section was flexing as though loose. As you say, the centre circular part is attached independently of the peripheral bolts. I’d not noticed it before and just...

I have just been cleaning my Pro C and noticed that the black plastic circular cover on the left hand side of the motor assembly is loose. It looks like it clips onto a black plastic carrier that is bolted to the main motor alloy casting. If I take hold of the cover I can move it around but...

I am knocking an LED rear light together and have a question regarding the power supply for it. The LED that I am using is a CREE emitter which requires an input voltage of between 1.9 – 2.2 volts and a maximum current of 750 mA. I will be powering the LED with a 3.7 volt battery via a...

My battery seems to have settled down now and the discharge is much more linear. This seems to have coincided with the weather turning milder around here. It was +9 degrees on my way to work and +7 on the way home last night. The battery is now behaving as it did in July when the bike was new :)

What sort of bike do you have? When I was at 50 Cycles last week, they said they were soon to be selling a 12 v portable charger for the Panasonic battery.

Well done Mattyduck. You won't regret it as the Pro C is an excellent bike that loves busting hills and it is fast too. I still keep sneaking into the hangar at work to just stand back and admire my Pro Connect and I have owned it since July. How weird is that sort of behaviour? It makes me...
