    My 1st ebike build - a folding 20" Dahon

    Greetings from U.K. I was most interested to read about your Dahon folder project, having carried out exactly the same type of conversion on a 20" Dahon Mu Uno I'd had for a few years. The conversion kit was a UK-produced Swytchbike, with a motor of the same wattage as yours, but from your...

    Electrifying my Dahon Mu Uno

    At lasr, at last!! My health has improved to the point that The Boss (i.e. my wife) has given me clearance to take a test ride. This is planned to happen on my birthday (I won't say which one) on November 2nd. I've not done much else to the bike since I last posted, except fit a set of...

    Electrifying my Dahon Mu Uno

    Here's an update on the situation with my Mu Uno. My medical situation hasn't changed, so I'm still unable to carry out the long-awaited road test. But what I have been able to do, though, is activate the Warranty on my Swytchbike kit. This involved completing a form online, and emailing them...

    Electrifying my Dahon Mu Uno

    At last! At long last!! My Mu Uno is almost ready for the road. I had no big problems fitting the Swytchbike kit, and the company were most helpful with any queries I raised, and always replied very promptly. Now all that's needed is a little bit of fine tuning, tidying up cables etc. Not...

    Electrifying my Dahon Mu Uno

    Update - I've ordered the Swytchbike kit, so there will be a bit of a wait now. In the meantime, there are a few things I can set up on the bike, and still be able to ride it "unpowered". I already have a magnet ring, so I can epoxy this to the crank on the chainring side, then fit the KT-D12R...

    Electrifying my Dahon Mu Uno

    Thanks guys for the advice - I'll certainly be following it! The TA's from Hammer are widely available here in UK. Bearing in mind the power of the Swytchbike motor, will I really need the 5mm ones, or will the 3mm be strong enough? I presume it's best to fit one on both sides, and OK to...

    Electrifying my Dahon Mu Uno

    I thought it was about time I got up-to-date with my Mu Uno project (assuming there's still somebody out there following this thread)! I got the rebuilt 406 wheel back, and today I fitted it with a 2" Big Apple, and it looks really good on the bike. I've ordered the Swytch setup, but at the...

    Electrifying my Dahon Mu Uno

    After having a new rear wheel built for the Dahon, when I tried to fit a tyre & tube on it (first, the original Schwalbe Marathon Racer, and then a Schwalbe Kojak I'd bought recently), neither tyre would fit and they just seemed to be far too small. It was then I realised my dumb mistake - the...

    Electrifying my Dahon Mu Uno

    You can't see in the foto, but just above the handlebars there's a small shelf with an audio cassette player with a USB port, so I can play back tracks from my MP3 player. I also have a tablet (which I haven't used in ages), so maybe I can resurrect that, and spin through some of the Tour de...

    Electrifying my Dahon Mu Uno

    While I'm waiting for a few more components for my Mu Uno, I'll digress slightly, and I'm sure the Moderators won't object. In addition to being a bike nut, I also like to keep pretty fit - I work out, and for cardio I use my Spinning Bike. It's based on a re-tired (or should that be...

    Electrifying my Dahon Mu Uno

    The first view is before assembling the brake arm to the hub - you can see the 4 protrusions referred to in the Youtube vid, and just about identify where they will fit after rotating 90 degrees. The other views are after assembly to the bike.

    Electrifying my Dahon Mu Uno

    I'm not quite sure how I did that, my PC has been misbehaving. Anyway, hope those pix posted OK. I didn't show the whole bike, there are some bits missing at the moment - no tyres or tubes (except for an old tube to protect the new rim), and no chainwheel or chain.

    Electrifying my Dahon Mu Uno

    So, I bit the bullet and went for it! With the knowledge gained from the Youtube vid, I removed the locknut & brake adjuster nut frrom the non-drive side (with the wheel clamped horizontally of course). The brake arm just lifted off, I rotated it 90 degrees clockwise and replaced it, with the 4...

    Electrifying my Dahon Mu Uno

    If you look at the fotos in the Bikefolded link, you will see that the Mu Uno doesn't really have round-section rear frame members, just one quite large oval-section member, ending in rear-facing horizontal dropouts. I still think that attaching various bars by means of jubilee clips (you might...

    I reckon it means that it's possible to turn the brake arm through 90 degrees!

    Take a look at this advertisement for a Sturmey Archer brake arm, then click on the small picture, which shows you what the rear of the assembly looks like.

    Yes, it's the same model as in the photos in the link. You can see the coaster brake arm attached to the frame in the 4th photo.

    Electrifying my Dahon Mu Uno

    Many thanks to your suggestions. The only thing is that Mu Uno doesn't have chainstays or seatstays as such, just a single frame member that slopes down to the rear dropouts, with a litle gizmo on top just above the dropouts where the brake arm of the (Shimano) coaster hub would attach. My...

    Electrifying my Dahon Mu Uno

    Oh, I forgot to mention that the axle has flats to correspond with the drop-outs, so it's not a question of rotating the whole hub into the required position, In only it were that easy!

    Electrifying my Dahon Mu Uno

    There's still one small problem that's been bugging me. Although it's not necessarily e-bike related, as it's part of my overall project, I guess it's OK to mention it here. As I already said, I've got to make modifications because the Sturmey Archer S2C rear hub is designed to be fitted to a...

    Electrifying my Dahon Mu Uno

    Thank you guys for your input. I think I'll follow my instincts on this, and give it a miss! I'll just use some paint on the chrome one, and kid myself. After a while, the bits that the chain hasn't worn off will still probably show as black!

    Electrifying my Dahon Mu Uno

    Re. the advertisement on ebay for the 14T sprocket in black, I emailed the seller, basically asking why they wouldn't ship to U.K. So he replied that he would amend the ad to remove the restriction for U.K. I thought this was very helpful, but when I realised what the overall cost would be, I...
