  Dear Mr Jerry Simon,
  I'm a local dealer of electric bike motors (with Tongxin motor) in Belgium.
  I'm looking for a little piece of the eletric motor kit of Tongxin. I need only the big steel ring around the little bearings. On the photos you posted on this forum I've seen the ring that I need.
  Where can I buy this ring? Or can you give me some usefull info about a European importer of these spare parts?

  Greetings,
  I'm new to this forum so I might not be contacting you properly. I'm interested in one of your 80mm motors for my brompton. How do I pm you?
  Thanks in advance
  Regards

  Hello Jerry
  I have a quote for £1.25 per spoke including brass nipples for my brompton Q85 conversion.
  For the radial length i have knocked off 1.2mm from what the on line calculator recommended. Does this sound ok to you? Much appreciated.
