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

Detail:

- Two front chainrings; 34 –50T;
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
-  Sturmey-Archer 70mm drum brakes
- Front light; Busch+Müller 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. (maintenance 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  indicates a departure from typical bicycle engineering parts to purpose velomobile stuff. 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 don'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 MTB cassette with a 40t lowest gear. I love the chain tensioner.
Also have a look at http://hilgovelo.blogspot.com/2017/11/the-hilgo-story.html for the development story by one of the Sinner people - Harry - to get a greater understanding of how good it is. You will see that it is shifted by two cables.
Now, can I come up with a home-made variation that I can swap in before I get too far advanced? It seems simple enough. Is there yet one more velomobile to build?

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

Re: New Technology

Got my rough version of the Hilgo gear mech started today. Didn't get it finished 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 make 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.

Re: New Technology

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 extent.

Re: New Technology

Kevin Crockett - VK3CKC
 

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 rider might be a noticeable change in the resting angle of the chain tensioner.

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

Considerations:

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

The height of the slider idler must be higher than the height of the bottom 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 chainrings, providing a low range and a high range of gears, selected as required for either hill climbing or flat/downhill riding. The ratio between the mid-drive output and the rear wheel sprocket (only a single required) could 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 incorporating in my current trike build - with an 8 or 11-speed of course.

Graeme, Trevor, Lloyd and Kevin are enjoying rides around the environs of Albury for a couple of days with a contingent from the Friends of the Bendigo-Kilmore Rail Trail.. Heading towards Tallangatta tomorrow. A good time being had.

Monday night sked

The one time I remembered I turned on and tuned in and I couldn't hear a soul!

Nevermind, I will try to get again.

Re: Monday night sked

Sorry, Paul

Graeme, Trevor, and me are in Albury, staying at Lloyd's place. It is part of a few days riding with a few from the Friends of the Bendigo-Kilmore Rail Trail. We had been out riding all day and had gone in search of "eateries". It was 7.15pm when I remember the net and us "Bendigonians" were hopping into lamb roast, etc., but I was not in a position to do anything as the car cannot tune 80m. When we got back, Lloyd said he went on, called, and heard nothing.

'Tis better to have triand and lost, etc.

Do you get an auto reminder from this group every Monday?

Re: Monday night sked

Paul Stampton VK3IH / G3ZDR
 

Yes I get the reminder - what I need is an electric buzzer strapped to my ear that goes off at 6.55!


enjoy your riding - I rode to work today in sunshine - actual sunshine!

A great couple of days with some very interesting "bits". Met two other Wodonga trikies - Wes and the "other" Lloyd.

Re: New Technology

I added a photograph of my "Hilgo" mid drive incarnation, to the Trio Photo Album. On and off, it took a week to make the bracket and fit it. I still have to properly fit the rear wheel drive sprocket and a small fitting to firmly hold things in place.

Bike Bendigo

Hi Everyone

Tomorrow is the regular Bike Bendigo Community ride - starts 10am at Ewing Park on the Bendigo Creek Trail, proceeds to Spring Gully and returns to Wolsterncroft Park. Graeme and I should be there.

Stay in touch with these regular rides and other activities at: https://www.facebook.com/BikeBendigo/ and support their efforts in building more cycling access in and around Bendigo.

Re: Bike Bendigo

Sorry I can't be there tomorrow, I've got something else on, but will look forward to the next one.

Cycle space on new V/Line trains

Kevin Crockett - VK3CKC
 

The new V/Line train carriages have space for 14 more passengers - at the expense of a toilet, cycle space and other item storage. Currently, the carriage of bicycles is at the discretion of the Conductor and groups are simply not catered for and are advised to make alternative arrangements. This is simply not acceptible in the interests of encouraging more people to use cycles. The new carriages make train travel to Melbourne for a day of cycling even less likely.

Want to take a part in trying to reverse the situation? Visit the Bendigo railway station for the 12:07 train arrival on Tuesday Nov 13 and rub shoulders with a few cyclists from Bicycle Network who are coming to Bendigo to meet with Jacinta Allen, Minister of Transport, and some Friends of the Bendigo-Kilmore Rail Trail members. Trevor and I will be riding to the Hargreaves St Mall for a cup of coffee and some public visibility an hour or two earlier if you want to join us. We will be then heading to the station for the train arrival.

Ride: Nov 23. Bendigo to Elmore and Return

Kevin Crockett - VK3CKC
 

Subject to weather, we are planning a ride, Starting from Lake Weeroona around 9.30am, to Elmore (about 45km), lunch at the Bakery, and return. Route will be: Bendigo Creek Trail to Epsom, Midland Hwy to Huntly, Old Murray Road to Elmore. A mainly flat ride.

Re: Ride: Nov 23. Bendigo to Elmore and Return

Kevin Crockett - VK3CKC
 

Well, the wet weather has put an end to the Elmore ride for tomorrow. There are two places that would be expected to be under water and the surface of the old road may also be a bit muddy in places.

Shall we look at it for next week?

Re: Ride: Nov 23. Bendigo to Elmore and Return

Graeme Knight - VK3GRK
 

Yes that will be fine. I forgot about those sections along the track, but they would certainly be full of water!

Re: Ride: Nov 29. Bendigo to Elmore and Return

Kevin Crockett - VK3CKC
 

Weather again. Not fancying battling a head wind on such a long ride. So, it's a ride to Lake Weeroona and Hargreaves Mall, Bendigo, instead, but one day ...
