B’Twin – A Corporate Velomobile Future?

A couple of weeks ago I saw my first B’Twin branded bicycle.  It was a fairly typical and non-descript hybrid MTB style cycle being used on a British Seafront.  It likely would have gone unnoticed altogether, as just another Bike Shaped Object moving in the shadow of the ICE recumbent Trike and the elegant Pashley step through I also saw, had it not been for some news I should have reported on earlier this year.

This may be a bit stale by now, but I became aware of B’Twin through a report on Recumbent Journal (RJ): a US based blog covering all things recumbent, including velomobiles.  RJ reported on a design competition posted at the opensource automotive design community The Forge. The stated object was to design a velomobile that could be built for less than $2000 for a given set of criteria, and a winner was announced at the end of May 2012.

The particular merits of the RJ report was not the comment on the various designs, from which they largely refrained, but rather the nature of the company sponsoring the competition and what the implications might be for the future of velomobiles.

A collection of 4 Velomobile Concept Designs

From top to bottom:
Torkel Dohmers’ “ThisWay”
Adam Lazenby’s “Skua”
Tim Turrini-Rochford’s “NoVelo”
Speed Studio Design’s “Trik-e”

Design competitions and velomobile concepts are not new. Various individuals with industrial design skills or academic interest have produced concept designs, several of which are included in the upcoming Velomobile Database. In 2009 the excellent Bicycle Design Blog, with an interest in tapping the huge “blue ocean” of potential utility cyclists, organized a design competition which was won by a design with many velomobile features. Last year, 2011, Bicycle Design was mooting another similar competition.  The difference here is, that this is the first time a commercial organization has done so, putting up a prize of $7500. This is significant as commercial organizations exist to make money, and do so by selling products to a market that is willing to buy them. As RJ points out, the group behind the competition sponsor, B’Twin, is the french based Oxylane group. Oxylane produces a large range of, often innovative, sporting goods and is considered to be the largest sporting goods retailer in the world. The implication being, they see a market, and one sufficiently large enough form them to swim in, ready to be tapped.

The designs (see the winner and some finalists shown below) have many things that could be criticized not least the failure to achieve the desired price point. However as RJ points out the motive behind sponsoring such competitions is to help stimulate the internal design team that is working on the project in a place where there are the resources to refine the design to the desired level.

The apparent convergence of the designs on the same configuration adopted by the recently re-launched Drymer, (upright, head-covered, tilting, tadpole trike) is a fruit of the competition specification but it does offer clues on the corporate mindset  which tends to be constrained by focus groups and ideas largely confined to an existing paradigm.  Something not quite so far removed from a recognisable upright cycle with a bit of automotive protection and styling would probably be easier to sell from that perspective.

Photos of Feetz tilting Trike and Veltop weather covering on a cargo TrikeHaving said that, one can already put together a machine with many of the desired characteristics by combining the Feetz tilting trike (Their Old Website), now supplied by the Belgian velomobile manufacturer Fietser, with one of the weather coverings by the french manufacturer Veltop. All for less than €1954 (349.00 + 1500.00 + 105.00) including VAT which works out at something like $2400 or £1600 plus delivery to your chosen destination. I had a short test-ride on a Feetz from Cyclesense in Tadcaster few years back, and left with a positive impression. It would be somewhat of a Kludge compared to the entries below but if you exclude the VAT and shipping it would certainly come close to the $2000 target of the competition. The item I find the most challenging is the requirement for eAssist as this currently adds a significant amount of both weight and cost.

Battle Mountain a week to go!

World Human Powered Speed Challenge 2012 PosterIn a weeks time an elite collection of racers, engineers and their supporters will be assembled in Battle Mountain, Nevada, USA.  Each will be attempting to break various current human powered speed records, even if only their own personal best from previous years.

This year is set to be of more interest than usual.  Not only will Sam Whittingham be defending his current 2009 record of 82.819 mph.  There is a very serious contender in the Dutch Universities of Deft and Amsterdam and their Human Power Team with VeloX 2, a significantly revised design of the the original VeloX they raced last year, and packed full of technology.  To round off the competition, outsider and celebrity Scotsman, Graeme Obree is attempting to not only break the current record but aspires to smash it!  In an echo of his 1993/94 hour records on an upright bike he is attempting to pass 100 mph on a prone, head first, bike he has designed and built himself.  It should be obvious that it is Graeme and his Beastie who are featured on this year’s Battle Mountain Poster.

There are some who are quite skeptical that 100 mph will be passed, especially on a first attempt, but none-the-less there are many who are rooting for the “Flying Scotsman” to do well.  A couple of articles give more detail, one from the Daily Telegraph and one from Road.CC.

A short video showing Sam’s record setting run from 2008 is shown below.

Below is a montage of clips from 2009 which should give an idea what SR305 will be like next week.

There is also a documentary being produced based covering the last three years at Battle Mountain called Human Power.  Production is expected to be finished sometime in 2013.  Mean time there are more videos available on Georgi Georgiev’s Varna Website, the designer and builder of the record breaking bikes.

The current list of race entrants is given on this page. And result will be published here.

Alligt, Jouta and the Sunrider Velomobile

Since taking over Sunrider Alligt has been busy developing and refining the design and build method.  Despite an external similarity there has been much changed “under the hood”.   Ligfiets.net has a brief article outlining the principal differences between the new and old versions and according to the comment by Jos Sluijsmans the new Sunrider 2.0 will be on display at the Velomobile Seminar later this week.

Jouta, whose own velomobile was covered in this year’s SPEZI report, now have their new website online.  In addition to their original front wheel drive delta trike and fairing they also report that they are very busy building sunrider velomobiles.  They say they are working hard developing a new type of sunrider.  It is unclear whether this is an independent effort or if it is being done in collaboration with Alligt.

Velomobile Crash Safety

Contrary to a popular misconception put forward by some, cycling is a safe and pleasant activity, it is not ordinarily a dangerous or extreme sport.  It should not therefore require a rider to don specialist protective clothing or equipment.  This can be amply shown from Holland where thousands (or is it millions?) cycle in everyday clothing without the dubious added safety of a cycle helmet and without any significant ill effects.

The velomobile, which enables a rider to go further and/or faster, often for less effort, due to it’s aerodynamic body, serves to extend this ideal.  As a side-effect, as it were, It also provides a substantial layer of protection in the rare event a rider is found in the path of danger.

David Hembrow, who himself rides a Mango velomobile, on his blog A View From the Cycle Path explains the reason why the Dutch cyclist is able to experience such safe and pleasant conditions.  Regrettably the standard of high quality segregated infrastructure has not yet arrived in most other countries.  It is therefore perhaps not surprising that the two case studies I was able to locate for this post were in Germany and the United Kingdom, where cyclists are regularly obliged to share the road, where and when, the risks for a high energy collision are much higher.

Front view of crashed Alleweder showing side impact damage.Firstly from Germany.  Jan P. Puchelt has a site dedicated to the Aluminum Alleweder in which he illustrates the protection benefit provided by a velomobile when hit by a motor vehicle and I quote below:

It’s obvious that crash tests like in the car industries are infeasible with the small-scale production of the Alleweder. So it is even more important to document any accidents that have happened with Alleweders involved. Helmut Kuske happened to have such an accident. He was driving on a cycle path alongside a country road when a car, which has ignored a stop sign at an entry, crashed sideways into his Alleweder A2. The car pushed him sideways across both lanes of the road. He was lucky that he sat in an Alleweder. Exept for an concussion and a few slight injuries he was not harmed! On a normal bicycle he probably would have been run over by the car and would have been heavily injured.

 

The front bulkhead has been massively distorted when absorbing the energy from the impact. But the rivet connection of the thin aluminium plates survived the crash
… the bodywork has been significantly distorted by the massive side impact. However, it has hardly been crushed. The driver has not been crushed in the Alleweder.

The second example was rescued from the now defunct velomobiling.com website and does not have any photo illustrations.  Tony Eastwood supplied an extensive report of a collision he experienced in 2004 in his home built velomobile in Wales, UK.

Coming up to Cae Afalau I’ll do a right hand bend at about 30 mph, a slightly gentler left-hand and then on to a great big open section that is one of my favourites. As I do the right hand bend I’ll really open up and hit my pedaling limit at about 35 mph – and it will be half-a-mile before I’m below 30 again. I look forward to a higher average.

 

I check the mirror for traffic behind me, there’s nothing. I get ready to take slightly higher line on the bend. A car, a black Fiat Punto, appears coming the other way. His back end swings out. I change my mind about the higher line on the bend and go for the kerb. The Punto oversteers, leaves the road, misses a telegraph pole and carries on spinning. He crosses the road towards me, broadside on it seems. I think I missed him – I’m wrong – he hits about a foot behind the front wheel. There’s a very short bang. I’m sliding along the road, I can’t see anything, something to do with the G force I think, but I’m still conscious. I come to a stop. I get easily out of the vehicle which is lying on its side – there is no roof any more, no wonder it’s easy. I’m alive, one of my elbows is wet and red but I’m alive, I can see, hear and still have all my limbs. For me life will still continue; I’ll still embrace my children, play the guitar, preach sermons. I’m euphoric – I look at my totally wrecked vehicle and and I’m still euphoric. I’m standing here alive, and well, and praising God’s providence in preserving me whole – I’ve just hit something at over sixty miles an hour and survived. My own vehicle saved my life – 8 years work gone in 1/20 of a second but I’d make the same bargain any time. The police man and ambulance man think so too – they are amazed, full of praise for the vehicle. It’s a wonderful accident – can you have such a thing? – I can simply walk away with just one small hole in my left arm, a reminder of what could have been.

 

No one else is hurt – the driver, a nice young man having his first accident, is terribly shocked but he’s OK. His car’s wrecked, my bike seems to have taken a lot off it and the wall’s done the rest. And that, I guess, is my last ride on a velocycle for some time. If I’m lucky the nice young man’s nice, kind insurance company will buy me a Leitra, Quest , or even pay for a replica – but as they say, the jury is still out.

He did replace his smashed velomobile with a Quest and supplied an impressive write-up which was published in Velovision Magazine Issue 25, March 2007.

Finally if any readers know of any other examples please share using the comments below.

Velomobiles – Good for your health?

One of the first examples I came across of velomobiles being put to practical use was in a back issue of Velovision Magazine. Having taken up a subscription in 2006 I began collecting all the back issues. The March 2006 issue 21 had the following article reporting on the Leitra velomobile being put to use by a number of German Doctor’s for home visiting.

The article entitled “Dr Leitra” is copied below.

A good example of practicing what you preach!

7th Velomobile Seminar Update

7th Velomobile Seminar

According to Ligfiets.net and the linkedin page, the number of registrants for the 7th Velomobile Seminar has not met expectations and as a result the costs of a 2 day venue can not be met.  The conference has therefore been shortened by one day.  Obviously this will be disappointing to many. The dates are now Friday 7th and Saturday the 8th.  A detailed program of the papers to be presented on Friday is now available together with more detail for the activities on Saturday.

Alligt to produce K-Drive elliptical crank system commercially

As reported on Wim Schermer’s blog the K_Drive elliptical crank system is to be made available by Alligt, the manufacturer of the Alleweder and Sunrider family of velomobiles. Alligt intends to present the new drive at the 7th international Velomobile Seminar in a few weeks time.

Alligt K-DriveLike many, if not all, modern innovations in cycle technology the K-Drive can be traced back to the period of intense creativity in the late 1800s. The modern form was developed by Miles Kingsbury and successfully used on the Kingcycle but the mechanism itself appears to have been first described in 1890.

The renewed interest, which has lead Alligt to start production, came from the University of Delft’s current attempt on the Human Powered Land Speed Record with their VeloX 2 HPV. To optimize aerodynamics the Human Power Team’s research and experience with VeloX 1, lead them to conclude that the way forward is to significantly reduce the frontal cross section of the nose. However the size of this section is determined largely by the swept volume required for the cranks, pedals and feet of the rider. It therefore became necessary to develop a transmission that could reduce the vertical dimension of this volume. Patrick Fenner of Deferred Procrastination calculates this reduction to be of the order of 45%. His post on the K-Drive gives a good overview and also includes a demonstration video of the Human Power Team’s drive in motion. Of course the proof of the pudding will be in the eating with 26 days to go till the test at Battle Mountain.

Battle MountainAlligt already produce a nice collection of specialist parts for recumbents and velomobiles and this should prove useful home builders and potentially commercial manufactures who are looking to emulate the approach of the Human Power Team and VeloX 2.

7th International Velomobile Seminar

7th Velomobile SeminarThere are a number of events of both cycling and velomobile interest in the next few weeks. Of particular interest this year is the 7th International Velomobile Seminar to be held in Dronten in the Netherlands. Velomobiles.co.uk is pleased to announce that we are registered to attend and expect to be able to report on all aspects.

Dronten is home to 3 of the 4 principal Dutch Velomobile Manufacturers, Velomobiel, Alligt and Flevobike, so the location makes perfect sence. The venue is De Meerpaal, a large event and conference centre, which is located in the centre of Dronten, not far from the town bus station.

The seminars have been held periodically since 1993 and serve to bring together manufacturers, users, policy makers and any one else with in interest in human powered transport and velomobiles in particular. The purpose being to share knowledge and best practice in both technical aspects and also social acceptance of the velomobile concept.

Number Location Year
1st Copenhagen, DK 1993
2nd Laupen Castle, CH 1994
3rd Roskilde, DK 1998
4th Intelaken, CH 1999
5th Gemersheim, DE 2004
6th Copenhagen, DK 2009
7th Dronten, NL 2012

This year’s event builds on previous seminars with two days of papers and presentations followed by a social gathering, at which there will be an attempt to break the Guinness World Record of the number of velomobiles gathered in one place. According to the provisional schedule Day 1 (6th September) focuses on the social and environmental aspects, particularly the World Class Dutch Infrastructure. Day 2 (7th September) is dedicated to technical presentations. Day 3 (8th September) hosts the record attempt and a velomobile tour.

Along side the seminar there will be an exhibition space both for the trade and enthusiasts with home builders welcome to exhibit their creations.

Registration for the event is not difficult, though it is a bit convoluted. You must first register an identity on the Dutch HPV Association website ligtfiets.net, which then allows you to subscribe on the event pages for either the seminar or the social gathering. Of course you are welcome to register for both! Payment details are then emailed to you. Preferred payment is by bank transfer and it was here that I had some difficulty, as my UK bank was requesting more information than was available in the registration email. Since it is Velomobiel that are providing the payment service for seminar registration, I was able to communicate with Ymte Sijbrandij directly, and complete my payment via Paypal.

So check back here on the 6th, 7th & 8th of September for our view from the centre of the velomobile world.

Summer of Cycling

Well I have been occupied doing other things for the past few weeks. Some related to velomobiles and some not related, and consequently, I have some catching up to do. An update to the blog is long overdue! Mid-summer is a quiet period news-wise but, none the less, there are some items that have been reported elsewhere, which I expect to comment on shortly.

More generally the current Olympic fever and the achievements of team GB in the cycling events is serving to heighten the British public interest in cycling generally, both for practical transport as well as for sport. Anything which helps improve the status of transport cycling can only be a good thing. Looking beyond the olympics the question of what to spend the Olympic Legacy on has been raised. Bike Biz reported that the BBC radio 4 program You and Yours was asking this question of it’s listeners. Bike Biz were strongly advocating it be spent on quality cycle infrastructure a-la the Dutch model. This has been essentially seconded by SUSTRANS who are calling for investment to encourage cycling to school.  A view with which we heartily concur.

There would also seem to be some increase not only in the profile but also in political support for the installation of better cycle infrastructure. The Times’ #cyclesafe campaign together with a high profile fatality connected with the London Olympic venue has served to raise public awareness, and political support, for serious improvement. Regrettably in the reporting of the fatality there were distracting comments about “wearing helmets,” raised by UK champion Bradley Wiggins and seconded by several shrill voices. The debate on helmet wearing and compulsion is largely removed from the world of rational scientific enquiry; and completely misses the point of how a 70 kg human and their 20 kg bike is able to stand up to a vehicle with a mass from 800 kg to upward of 3000 Kg. It should be obvious that these fatal “accidents” usually involve forces, and levels of energy, far exceeding that which a cycle helmet is capable of absorbing. Indeed, it was the writer’s own experience that, a healthy human skull is perfectly capable of exceeding the rather limited performance required of cycle helmets*. (If it helps, consider how easy it is to break a cycle helmet with your arms versus breaking a human skull!) I might write a post describing my own experience in detail, together with my observations, on the limited value and potential risks, of helmet wearing in everyday cycling, at some other time. I also intend to write a post about the protective benefit provided by a velomobile body when involved in a collision.

Continuing the theme of infrastructure, I had the opportunity to attend my local government Cycle-Forum, which I found very interesting. The Forum meets quarterly and serves to try and coordinate efforts to promote cycling and invest in better cycle provision locally. A promising activity which needs support, and can only get better, with consequent beneficial results for all pedal powered transport.

However I will return to velomobiles with my next post.

* Vertical impact at 11-15 mph assumed to be equivalent to falling over from a stationary bike and landing on your head. See the section on Standards on cyclehelmets.org

13 year old makes news at Human Powered World Championships

A young teenager in a HPV managed to make news in sources as far removed from cycling as RushLane, an automotive news site, ewandoo, a technology blog, and even the Daily Mail, a newspaper not known for it’s pro-cyclist reporting.

13 year old British boy and his HPVTim Parker the 13 year old son of Chris Parker, of the recumbent trike makers ICE, won the World Championship in the junior class, on a fully faired trike, not surprisingly, made by ICE. His achievement is remarkable in part because he was able to beat competitors with ages up to 16 and, while in no way undermining Tim’s achievement, it serves to illustrate the benefits a fairing confers on a HPV. It no doubt took some athletic ability but also maturity, to successfully manage both the human engine and the machine he was powering, to victory.

The Use of an ICE trike as a platform for a HPV or velomobile is not new, both Ocean Cycle with their Challenger, and Nimbus Kayaks (Velomobiles.CA) in Canada with their Borealis, already do so.
