Thanks for your comments and suggestion's. The Ping BMS I'm using is the high rate version. IIRC it is good for 60A continuous and upto 100A for a couple of seconds. I think it should be fine.
Where abouts in Blighty are you Geoff?
Your ebike is great!! You might want contact Johnrobholmes for the highly quality rim and spokes. I learned from GCinDC's review on his new rear rim and spokes. he sent his 9C motor to Johnrobholmes and He put best high quality rim and spokes and GCinDC tested stress and abuse on new rim showed high strength and stronger!! Excellent service

I just killed my 9C 9x7 hub motor *sighs*
Your battery box hang on top on the frame. It gives you great balance and this similar Rebelpilot's ebike. It made me want relocation my 20s2p to front as similar yours.
keep it up!
PS. I see you upgrade full length front suspension fork. I am curious how much cost the full length suspension fork and I seems cant find these full length fork anywhere. Is your full suspension comfortable like plush soak the bumps?
We actually designed the 9C 9x7 windings in 2007.( It was actually Jerry one of our local dealers that designs brush-less motors for RC airplanes) We worked with 9C at the time and they only had the 8x8 windings available as they mostly sold in Europe.
We have re-designed the our DD motor 3 times since then.
1. We are using 9x7 windings.
2. We increased the thickness of the internal wiring. (this allows for higher voltages and higher torque due to no heat loss)
3. We use higher end hall sensors.
4. We changed the outer ring that holds the magnets from aluminum to steel. (this gives us about 5% more torque and 5% easier freewheeling)
5. We changed the thickness of the spokes as well as the way they are laced..
6. We redesigned all kits to have the ability to install ISO standard disk brakes (simply swap yours over from your rim)
7. We centered the axle so that dishing is no longer required.
Overall it weighs about 1/2 lb heavier.
Thank you for contacting us!.

un-lucky about your rim mate. I have had a quick look on tartbikes and the only rim that I could see that is remotely close to ERD of 530 is a EDR of 532 and that is one hell of a wide rim as well 4.2cm!, tartybikes do a very good range of ( sizes ) a very good quality spoke ( may be worth going for a different rim ) . I also like the forks you have now as well , I have managed to get a nice set of tripples for my bike now also . I also bought a, what have turned out to be a very nice rear shock ( for my new FS build ) new from a supplier Â£34.00 +pp , a absolute bargain (190mm i2i) , its not the lightest shock but do appear very strong and well made and fully adjustable as well ( very smooth and progressive ).
Good luck with the op.
The op went well thanks Kevin. Just got to keep the sling on for at least four weeks which is a bit sh1t.
Thanks for the Tartybikes heads up, they got some very nice stuff. I did manage to find an almost identical rim that is sold by various companies in the UK. ItÃ¢â‚¬â„¢s a Rigida Matrixx. I now I now, itÃ¢â‚¬â„¢s a cheapo rim but the bike will mainly be used for commuting so should be good enough. I am assured that the 36 hole pattern is evenly spaced even though the images on every web site I've seen it on show a grouped pattern. I also ordered some chainsaw files in case I need to file out the eyelets (thanks Ypedal).
What forks did you end up with? Also have you got more info for the rear shock or a link?

I have a question for the collective. I've been thinking that it might be a good idea to rig up some kind of ebrake switch to at least one of my hydraulic brakes. I've read quite a bit on here about reed switches and the mounting thereof and couldn't help thinking there must be an easier option. So I've been scouring the net for a Pressure Switch that I can add to the hydraulic line of my brakes. The only two that I managed to find are linked below but they are meant for cars/motorbike so I assume the activation pressure will be too high and they will be a pig to integrate.
Has this been done before on an ebike?
Can anyone point me to a more suitable pressure switch or more user friendly electrical switch setup?
Many thanks guys and please don't hesitate to coment on this one.

Are you running a front fender?
I see one in one of the pics.
Might help with weatherproofing.
