    New Super Light Tongxin Motor Design/Kit

    Progress has been slow mainly because I have been plucking up courage to take my dremel to a £270 set of Brompton Titanium forks! Anyway I have started now so there is no turning back :p I had considered chickening out and getting a set of steel forks, but that kinda defeats the object really...

    1940's bike factory video

    Absolutely fascinating! Blocks of metal come in one end and a bicycle comes out the other. Everything made and assembled in the same place. I loved watching the wheel building. What also amazes me is watching the mind numbing work of the repetitive tasks. I guess they would swap workers...

    New Super Light Tongxin Motor Design/Kit

    Neptune yes that is the power lead but its coming "from" the controller to the battery so no voltage on it to measure until after you connect it up! Some controllers do have a polarity safety for connecting up the wrong way round, but not an ideal way to test it. As I said hard to determine...

    TSD85F small hub motor - 83mm fork width 1.6Kg

    Richard, Outrider also seem to be aware and are part of the Tongxin Goldant motor development too. All very confusing. Regards Jerry

    Security of bikes...how nickable?

    I can :p Seriously, I insure my bikes which contributes to peace of mind. Also if I know I have to lock my bike up in town I take a non assisted old banger. Jerry

    New Super Light Tongxin Motor Design/Kit

    Thanks Dan. I think the pedelec parts are slightly different on this. Going to be another week or so before I can sort it out and test ride it. I might try and set it up on the current Brompton which will speed up a first test ride. Regards Jerry

    New Super Light Tongxin Motor Design/Kit

    Maybe not sure. I did notice if you speed up the motor at full cadence and then stop, it does bring the motor to a standstill fairly abruptly. The controller seems to be more intelligent or interacting with the motor better and more smoothly than the stock Tongxin one, in terms of smoothly...

    New Super Light Tongxin Motor Design/Kit

    Ok here is the video of it working. The wheel is not yet tensioned/trued but it gives you an idea of how it all works. The pedelec disk seems to fit but will need a slight modification to make sure it does not foul the BB. The pedelec sensor, or whatever is called, should fit stuck to the bottom...

    New Super Light Tongxin Motor Design/Kit

    Ok now we are getting some where. Motor laced not yet tensioned/trued up. In the end I had to go for alternate spoke head in/out to take account of the alternate hole counter sinking. Still radial though. As highlighted there was concern that the outbound spokes may not clear the fork...

    New Super Light Tongxin Motor Design/Kit

    Lukas, You are going to have to wait about a week until I finish building this wheel and fit it. Only got it a few days ago. Assisted speed on the flat will be 15mph for this 260RPM version in a 16" rim. You will need to to get the correct RPM for the wheel size you want to fit it too...

    Front wheel hub kits. a few questions

    Welcome to the forum 20ston. From where I sit, I see that the suppliers on here are very helpful. Some of us just love to tinker and have a go at putting together our own kits and tend to post lots of details of our projects. I myself started with a kit from Alien. I then wanted to build...

    Here's a Numpty Question!

    Thin bald tires (with kevlar belt) for better rolling resistance i.e. faster. Tires at higher pressures tend to roll faster. Keeping them at a higher pressure also helps prevent puntures. Regards Jerry

    Here's a Numpty Question!

    My guess would be around 50-65 PSI. My Brompton Kojaks are 110PSI! Regards Jerry
