Hi, Now I am getting back into doing conversions I have quite a few spares that need to be cleared from my stock. If I cant sell this stuff here I will put it on ebay without the offers to help with conversions and lace up wheels. Hopefully give something back to the forum if Brompoton owners...

Well after a bit of a break from all things Ebike I am back this time moving to the dark side of large wheeled bikes and rear wheel motor conversions! I have a lot of experienced in converting small wheeled bikes (Bromptons) and cut my teath on learning to build small wheels with Tongxin motors...

Hi again. Now I am retired and have a little more time to play around, I was thinking of getting a larger ebike to supplement my E-Brompton. I notice Halfoirds have their Carrera Crossfire-E on special offer and with membership of British Cycling club there is another 10% off. I almost prefer...

http://www.telegraph.co.uk/news/uknews/road-and-rail-transport/11808866/Electric-bikes-hit-streets-to-take-the-sweat-out-of-cycling-to-work.html Not sure if this has been posted before. I love how these reports talk as if no one has been cycling ebikes before "Electric bicycles promise to...

I am doing another conversion and want to fit a rack mounted battery so it can be left on and does not need to be carried around (usually they are hidden under panniers) but not sure what to get. It needs to have a plate on it so I can fit it on to the rear rack. Here are a couple of options...

Posted over on the Bromtpon forum :( http://www.theguardian.com/film/2015/may/03/bikes-vs-cars-film-war-cyclists-drivers-fredrik-gertten-interview "In Toronto, they’ve painted over the bike lanes. And in São Paulo, a cyclist got his arm torn off by a car that didn’t even stop … We knew it was...

Please note this is not my bike for sale but someone who has stolen my pics and description. http://www.ebay.co.uk/itm/Brompton-...1705664292?pt=UK_Bikes_GL&hash=item3ceedf8724 I don't know if to be offended or flattered lol Thanks to Chey03 for alerting me. Jerry

Just saw this on youtube Jerry

Ok like me up until a couple of weeks ago you have probably never heard of this http://en.wikipedia.org/wiki/Khat The sorry saga started about 6 weeks ago when I was approached by a forum member to build him an electric wheel for his Brompton. The forum member was based in the USA. I don't...

Seems like quite a nice/professional conversion. I recall seeing these somewhere else as prototypes. I don't think they ever went into mass production. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=321329745889&ssPageName=ADME:B:SS:GB:3160 When I had one (shown below), my conversion was...

Bulk charging DIY A123 LiFePO4 and Konion Li-Ion packs NOTE this post covers DIY battery packs not commercial ready built batteries where you should use the recommended charger ONLY As you know I have been building A123 packs using nominal 3.3V (3.6V max), 2.3Ah capacity cells for a while. I...

Given all my playing around with batteries and kits think its about time I treated myself to a decent bench variable power supply :p Seems you can pick up a 36V one pretty cheap. DC Bench Power Supply Switch Mode Adjustable 0-30V 0-3A CSI 3003SM | eBay This one is switched mode though. you...

I never realised that you could now get the original narrow 80mm wide Tongxin "nano" motors in the higher RPM, i.e. I thought the max was 260RPM After correspondense with Anna at Outrider I just received two 36v, 28H, 290RPM motors to try. Although mostly I use the smaller Keyde motors in my...

I have a few Tongxin/Keyde, lightweight, light assist very quiet front hub motors/kits spare if anyone is interested. First up is a narrow width 80mm, 36V, 260RPM/28H Keyde pedelec only kit in a 16" Brompton 28H rim. Comes with all parts including new sensor/magnetic ring, cutout brake lever...

Been meaning to post this upgrade to my Brompton for a while. Firstly thanks to Dave for sending me a set of these nifty little devices. I have since ordered a few more sets from China. Firstly I hate these cheap nasty generic cutout brakes but they were the only things that fitted with my...

Does anyone have a source for these ? I emailed Tongxin but they want $80 postage! Maybe BMS battery would be cheaper though I cant seem to find the three pin female connector wires on their site. Regards Jerry

Seems Halfords are selling 2012 models off cheaply. I just put a deposit down on one for my daughter to try. She has M.E and I built her an ebike a few years ago which she uses daily, but its in need of replacing now. This one is going for £375 with a 12 month warranty ? These listed at £1499...

Ian pmed me as a guest asking some e Brompton conversion questions. As a guest pm I cannot reply ? Never had a pm from a guest before ? Ian if you want a reply then please feel free to join the forum or send an email to jerrysimonsimon@hotmail.com. Regards Jerry

Because of the numerous post and repeated replies about adding electric assistance to the Brompton, I have volunteered on the Yahoo Brompton forum to updated the associated wiki page with a summary of what is possible/available. Its still very much a work in progress and the challenge is to...

Ok I have ended up with too many spare motors (nice problem to have) and thought maybe I would sell a couple on to members on the forum. I have two of these narrow (80mm wide) motors 36v, 260RPM both 36H. These are easier to fit to narrower forks found on these folders with minimum spreading...
