Looks good - I like the frame mount system for the battery

I had a strange thing happen once to my old Bosch battery - it began to stop charging at 4 green lights instead of the usual 5. A few runs on it to completely run it down flat and then recharge sorted it out. Sometimes the BMS can certainly go a bit odd at times in batteries. You could also...

I guess so flecc! They will have to think of the letters to go with something sounding bike related. Here is my mechanistic sounding one - not catchy enough though... PACES - "Power Assisted Cycle system - Enhanced Speed". My guess is that the speed restriction lifting trick will be like the...

Just thought I would post an update on how the new re-celled battery is going. So far I have been using it at least 3 times per week for my 13 mile commute (26 mile total distance) into work and it is lasting per charge, about 15% longer than the 8.8aH conventional battery. A small improvement...

I would like to test ride a STEPS equipped bike one day. I expect also that someone will figure out how to make it go faster than it should...

Hi Rob, I contacted about 3 suppliers of the Bosch style battery but they all sent me quotes for either a whole bike or a deep cycle lithium battery (!!) Despite me using the text in the subject line "Bosch compatible 8.8aH frame battery" and it linking to their product! I will try again and...

Bloody hell - just noticed not two motors but 3??!?? d8veh - surely you will be the fastest there?

My Bosch de-restricted and set to Speed 3 mode won't be able to keep up with hub motor power in that competition. Then again, if people were riding up it on non electric bikes I reckon I would have a chance of coming in the top 5 :-)

Been reading about that too - the only work-around would be to salvage a working BMS from another pack or purchase a non genuine battery which will almost certainly not have the shutdown feature installed. Then when these cells deteriorate, replace with better quality ones. Makita and others...

And the frustrating thing about that ISIS bottom bracket arrangement crank is that it cannot seem to be adjusted. It looks like it is a press fit arrangement, so if excessive play develops, Bosch just send in a new motor rather than replace the actual bearing (they must have quite a few...

Very true. On this forum you will find very experienced people who will be more than happy to share their expertise regardless of who you are.

From what I have read, a microprocessor CD welder will always be much more consistent compared with a standard SCR fired one. It will take a long time to build this but I am sure to learn a heck of a lot more about electronics in the process!

Ah, the perks of the job! Me being the waste manager has its benefits!

I'll be watching you guys then - the venue is only a few minutes from where I live!

It certainly is. One challenge will be actually getting all the components. I think a combination of eBay, aliexpress, Farnell and maybe Maplins will be used. Also, several visits to our electrical waste holding area at the hospital I work at might well be in order to grab stuff for cabling and...

Be assured that it is definitely fixable. I had my Bosch unit making a kind of squeak/whining noise. Turns out that the fix for the popping noise sorted mine out. The time when you need to be really concerned is if your motor unit has excessive play in it. This happened to me in the first 3...

As for battery tab welders I am going to build this one: http://frikkieg.blogspot.co.uk/ It looks like the best one around for giving consistently good welds and you can buy the PCBs and all the instructions too. An SCR fired one will work but I want to build one which is close to or in fact...

We did so well in the Olympics - especially with the cycling. It is a great shame that our successes never really got sustained recognition. I think it's mostly due to the money - think of football and the colossal amounts of money thrown at it all with promotion and the rest. It is a massive...

Good work! I was actually just looking on the net as well for them.

When I got my new batteries from the supplier in China I was very impressed with the customer service and their turn around time. Also, they only sell high quality branded industrial cells and they know exactly what batteries to recommend for e bikes. 10/10 all round.
