    If you are interested in a new velomobile gearing technique, have a look at=
    https://www.youtube.com/watch?v=3D-LIyl4aGpac. This allows almost all the = drive mechanism to be inside a velomobile body, out of the dirt and dust. T=
    he mechanism was developed by Drymer and Sinner Bikes. The Drymer-Sinner Hi= lgo velomobile will only set you back 7,750 Euros.

    Detail:

    - Two front chainrings; 34 =E2=80=9350T;
    150mm SD-cranks standard o Shorter cranks are possible
    - Shimano 105 11-Speed front derailer
    - 11-speed chain KMC
    - Sunrace 11- speed 11-40T cassette
    - Shifting system developed by Drymer - Sinner;
    o Super light shifting
    o Super fast shifting
    o Intuitive handling
    o Wide gear range
    o Drop - in mid-drive axle
    o Optimal chain tension in every gear
    o Robust
    -=C2=A0 Sturmey-Archer 70mm drum brakes
    - Front light; Busch+M=C3=BCller IXON- X E 150LUX mounted in the nose.
    - Interior LED light
    - 1 PC. Battery 12V
    - Tires; Rear maximum 55-406; Front maximum 44-406
    - Suspension; McPherson front struts, rear Hilgo shock absorber. (maintena=
    nce free)
    - Self supporting, removable seat (glass fiber)
    - Cateye Enduro 8
    - Wheel covers black
    - Mirror Zefal Spin

    The way of the future in velomobiles? The Hilgo mechanism=C2=A0 indicates =
    a departure from typical bicycle engineering parts to purpose velomobile st= uff. The derailleur system looks like it is a push-me-pull-you affair with = two cables. Easily replaced with a stepper motor? Now there's an idea. I do= n't know if there is any cassette on the rear wheel. Possibly not as there = are 22 gears available in any case. Note that the mechanism has a modern MT=
    B cassette with a 40t lowest gear. I love the chain tensioner.

    Now, can I come up with a home-made variation that I can swap in before I =

    I purchased a steel drawer slide to use for my version of the Hilgo transmi= ssion. Just to get it working on a 7-speed first and then installed in the = current trike build with a possible 11-speed..

    Got my rough version of the Hilgo gear mech started today. Didn't get it fi= nished but got a 7-speed mid-drive set up on a bracket and the gear change = idler wheel on a bracket and fastened to the drawer slide. Only have to mak=
    e up a tensioner and remove the bottom bracket/front boom from the trike I =
    am building, mount them on the side of the work bench, make up a chain, and=
    see what happens. Changes will be made by hand moving the slider. An hour =
    or so tomorrow afternoon should see an adequate test.

    Didn't quite get it finished. Now have mid-drive, slider, tensioner, front = bottom bracket, and a chain ready to size. The chain routing with the test = rig needs a bit more thought. Tomorrow should see it operating - to some ex= tent.

    Ah, the sweet, sweet, smell of success. Got a rough lash-up clamped down in=
    various places, sufficient to give a validation test. It worked. You just = move the slider until the change takes place. A visual indication to the ri= der might be a noticeable change in the resting angle of the chain tensione=
    r.

    I used a 14t-28t 5-speed mid-drive cassette mated with a 28t-48t triple ch= ainring. Used derailleur idlers were used for the change slider and the cha=
    in tensioner. The chain guide idlers were substituted by a length of 3/4" p= ipe.

    Considerations:

    Larger idlers might be required for the slider and chain tensioner use. Th=
    eir positions relative to anything else may need fine tuning.

    The height of the slider idler must be higher than the height of the botto=
    m of the smallest cassette sprocket. This will automatically make it higher=
    than the bottom of the largest sprocket.

    A triple chainrig might be used in place of the Hilgo double but it would = probably be pertinent to bypass it in operation to avoid overlapping gears.=
    A spreadsheet showed that the gearing should be sufficient with only two c= hainrings, providing a low range and a high range of gears, selected as req= uired for either hill climbing or flat/downhill riding. The ratio between t=
    he mid-drive output and the rear wheel sprocket (only a single required) co= uld be selected for even higher or lower overall gearing.

    All in all, it seems like a great idea and one that I will be looking at i= ncorporating in my current trike build - with an 8 or 11-speed of course.

    Like termites, just because you can't see me doing anything, doesn't mean I=
    am not doing anything.

    I now have all components of my "Hilgo" transmission copy made up, tried i=
    n situ, and it works a treat. A little bit of tweaking regarding final posi= tioning of all components and trying various spring loading of the front ch= ain tensioner and it is done. Images available when I get it all finalised.=
    I can then move on to the front suspension and steering. The end slowly dr= aws near.

    Success! I made up a very rough bracket to hold the gear change slider firm=
    ly in position to see how it worked without being able to move other than a=
    s it should. Changing was feather light and positive. The rig is not good e= nough for photographs as yet.

    Normal derailleur levers will not be suitable as it requires a push/pull a= rrangement. I also think that the required cable movement will probably be = more than a standard control may provide. I think I will be making up a sin= gle lever - forward to slow down and rearward to speed up. Shouldn't be too=
    difficult but will have to wait until later.

    Success! I made up a very rough bracket to hold the gear change slider firm=
    ly in position to see how it worked without being able to move other than a=
    s it should. Changing was feather light and positive. The rig is not good e= nough for photographs as yet.<br /><br />Normal derailleur levers will not =
    be suitable as it requires a push/pull arrangement. I also think that the r= equired cable movement will probably be more than a standard control may pr= ovide. I think I will be making up a single lever - forward to slow down an=
    d rearward to speed up. Shouldn't be too difficult but will have to wait un= til later.
