Maybe. Maybe not.

*
Ist May 2011 Sunday. 46-53F, 7-12C, windy, cool and sunny. And smelly, of course. Today's rain was cancelled due to excessive sunshine and shortage of clouds. It's an ill wind..

Rode on the Higgins snail to the shops and returned laden again. (the "snail" is a reference to the sheer capacity of my new shopping/saddle bag and the weight of its contents when fully stuffed. Higgins shopping trolley is now too conservative a term. 

It was a bit too cold for fingerless mitts again but I persevered. I had no choice since I had no gloves with me. My knees complained as I left but it soon passed off. I wish the wind would give it a rest. The same pattern day after day. Chest still bunged up. Still a bit breathless.

Spring has truly sprung with the arrival of the first swallows. The whole place has been freshened up with a thick coat of bright green, well dolloped over the landscape. Lots of plovers acrobatically defending their nests. A scruffy Jay flew over my head and stopped to stare from the hedge. Obviously never seen a racing trike before. A few yards on and a yellow hammer did the same trick. First this year that I've noticed.

The woods and hedgerows are packed to the gunnels with singing birds competing for attention. Small groups of geese rest by every polluted puddle in every field. The air is full of birds of prey pretending to be gliders. There was a real glider overhead yesterday. All very pleasant and rural. Except for the industrial quantities of pigshit and cheap scent and unknown chemicals being liberally splattered all over the beautiful Danish landscape. There really is no escape from the pong and the spraying! Two days in a row I've been sprayed by tractors running along the edge of the field right beside the road.


Here's one for Gunnar. Taken last year. The story goes that in the late 1700s a rich, local landowner demolished parts of the old church and rebuilt it with a tall tower and observatory. Whether he wanted to see all of his land in one go, or a view of the sea, I'm not quite sure. . Here's the full story in Danish just for Gunnar. :-)

I have cropped the left side of the picture to remove parked cars. Also hidden a hideously intrusive no waiting sign centre right. Cars and street furniture completely spoil many photographs. They date the view and drag one's attention away from the subject and the peace and quiet of the countryside. I prefer a timeless quality in my pictures.

  ---------------------------------------------------

A couple of cyclists, out training, passed me. A few leisure cyclists waved. I paused by a lake to snack on my biscuits and watch fish rising to flies. The air has been incredibly clear over the last couple of days. Not at all what you'd expect in a drought. April 2011 set a new warmth record in Denmark. Sunny too. 19 miles so far. Mostly into headwinds. I must take more photographs!


All there is between me and these monsters is an almost invisible, electric fence. Shields up, Scotty!


2nd 46-47F, 8C, strong winds, sunny. I woke feeling snotty and dizzy with tinnitus but hoped it would go away. So I put on long fingered gloves and set off into the wind. Very hard work it was too fighting the cold wind. My legs were tired and achy today. Probably all the ladder work.

The Ventus GPS logger hasn't recorded a full track for a week now despite being fully recharged and the data cleared every day. It just loses the plot and dozes off. P.O.C. 19 miles.


The unspoilt, abandoned, rural railway lines of Denmark. The barrier is to stop the hired pedal trolleys from running straight across the road. Also, presumably,  to stop access to cars and motorbikes. BTW: "SKUB" just means "PUSH" in Danish.


Anyone would think that these lines would have been made bicycle friendly years ago. They are certainly much used by local, pedestrian traffic and as dog toilets. The only wheeled devices running along here are the hired pedal trolleys. Of which there seem to be not all that many. All it would take to make these tracks multi-user friendly would be some self-stabilising gravel. At the moment even mountain bikes would struggle to make any progress.

It seems shocking to me that these wonderful routes are so underutilised. Particularly as the traffic on the minor roads and lanes constantly increases. It took me ten minutes to capture just a few shots without vehicles intervening. Most drivers were travelling above the speed limit despite the proximity of a school and the local shops. The crossing is right in the middle of a village. The rusting supports for the old road barriers can seen to left and right.

These railway tracks often follow, almost flat, direct routes between places. The dense, mixed hedges offer the shelter which the farmers have denied the minor road users in many places. These old tracks would be absolutely ideal for commuting! Yet I never hear of any campaigns to turn them into proper cycle routes.

I doubt the present, right wing government truthfully gives a damn about bicycles. Though they may make all the usual noises about green issues they can't even match their previous promises on C02.

Turning these routes into cycleways make an ideal project for all the unemployed. Whom the politicooze want to force into working full time for only their unemployment benefits. What a shame we can't force the present politicooze into unemployment! These trough dwellers moan about the population being overweight and lacking exercise. Who really wants to get off their fat arse to go for a walk, a wobbly, gasping jog or a slow, snaking, uphill, bike ride in heavy traffic? Surely a quiet, flat, rural cycle path is a much better spot to have a heart attack in some privacy?


Mr Higgins eyes up a buxom lass loitering at the supermarket.

3rd May 40-49F, 3-8C, breezy, cold, sunny periods. Overnight frost with the grass all white! Just a gentle tootle to buy some food. I rode through some woods to see where the enticing tracks led. A bit silly really because I ended up quite near where I had left the road in the first place. The trike handled well on the heavily rutted tracks. I put the front wheel on the grass ridge in the middle. The rear wheels ran quite smoothly along the bare earth in between.


Mr Higgins goes off-road.


 Mr Higgins sums up the courage to venture into the deep, dark woods.

Only 14 miles.

4th 39-47F, 4-8C, breezy, sunny periods, cold and stinky. Frost overnight. Grass white and frost patterns on the car. I was quite cold as I changed the front brake for another centre pull. The hex, brake extension bar is not quite straight on my Higgins. So I needed more clearance to avoid the brake block rubbing on corners and heavy camber. This may have been the "new" Shimano front wheel flexing more than the last one. Much better now but my brake cable is a bit rusty so should be changed' soon. Only a short run to the shops today. 12 miles.


Mr Higgins stops to chortle at the wonky spray tracks in a field of oilseed rape.

5th 46-55F, 8-13C, windy, sunny. What a disaster! I couldn't get any bread locally so had to go further afield into the strong headwind. Then I circled back to the shops I needed. I was so late I decided to take a shortcut through some woods. I was congratulating myself on bombing along at 12mph on rutted tracks when I punctured on a rock! I put a new tube in and pressed on. Then I took a wrong turn and ended up miles away from where I was going. This after doing a snail's pace for ages to avoid another flat tyre! Three hours to do 28miles!

I checked the punctured tube back at home. It had two snake bites at 90 degrees to each other along the tube. I am trying Alan's Super Patches again. This time I'm going to carry a spare tube with two of these patches fitted. I was very careful in my preparation and they stuck down really well. They will have time to adhere even better before being eventually subjected to high pressures. The last time I tried a Park Super Patch in an emergency it lifted soon afterwards.

None of my conventional glue patches were small enough for these narrow Bontrager 700C tubes. I couldn't get them to stick right around the circumference so had to peel them off again! 


I passed an industrial pig effluent production plant where five tractors were sitting with their engines racing. Three were stirring a giant, round concrete tank full of stinking slurry. Two others were waiting to load their spreader tanks. A little later a slurry spreader came roaring down the middle of the lane forcing me off the tarmac and into a field! Its flexible hoses were swinging wildly as the driver chatted into his mobile phone. He swerved away just as he reached me. A mile further on a modified tank/container had a big diesel engine racing as it stirred yet more slurry. My clothes stink of pig shit every time I come home.I can sometimes smell it on my own breath after a ride. This can't be healthy! It is no wonder I have bronchial congestion for months on end.



And, on a lighter note: Who said wind turbines can't be beautiful? The trick is to have small groups in straight lines dotted about the countryside. Three is a good number for one site. This picture was taken straight into the sun. It is far more impressive full screen.

Mr Higgins investigates dappled shade.

6th 50-60th, 10-16C, sunny, winds lighter. A figure of eight shopping trip. I was going well today. Even cruising at 20mph for a while on the flat with a gentle tail wind. 23 miles.


Beech woods are glorious at most times of the year. Each season presenting a different colour and a wholly different light.

Out of curiosity I weighed my shopping when I got home. 17lbs despite it being rather less than usual. Only one and half carrier bags full instead of the usual two full carrier bags or even three. I have obviously been underestimating the weight I am carrying. 20+ lbs is a much more likely total. Which has to be added to my usual, ready-for-the-road 38lbs. So when I'm carrying milk, potatoes and a few tins I could easily be dragging 60lbs all up weight. A Guru Photon racing bike weighs 10lbs complete. (without shopping) I'd need at least three sky hooks to get Mr Higgins that light! :-)

I'm getting rather ashamed of Mr Higgin's tatty appearance again. The question is what to do about it. Patch up the missing paint? A total repaint? It will have to be cheap and DIY. I'd also like to keep (or replace) all of the transfers. (decals) I still like purple/mauve but would prefer something a little stronger. Perhaps even (gasp) metallic!

I was replacing the worn headset bearings today and used the opportunity to thoroughly clean the forks. The underside of the forks are not usually accessible to cleaning unless the trike is inverted and the front wheel removed. Inaccessibility also applies to fifty seven years of sunshine. The hidden areas were unbelievably deep and vibrant! It positively glowed with the richest purple imaginable.

An odd discovery was that somebody had used Araldite or epoxy to pack out the steerer tube. Just to provide a decent seating for the lower head bearing race. The usual raised bearing seat was barely 1/16" deep in places with a very wavy top edge! The epoxy had been used to deepen this seating. Presumably using a greased bearing race to provide its own mould. I tried a used Shimano 105 headset but it was too deep. So I was forced to use an older set from one of my recycled donor bikes. At last I have a smoothly turning headset without slop. I have yet to ride it but will know tomorrow if the work has been worthwhile.

 A cycle path lined with saplings which haven't yet come into leaf. The surface is superb apart from a couple of potholes. Quite a long climb but at least the traffic is at a safe distance. The absence of traffic gives a cycle path entirely its own atmosphere. The birds are also much more numerous.

7th 55-65F, 13-18C, windy, sunny. It¨s all very well being able to cruise effortlessly above 20mph but one always has to return into the head wind. The headset must have bedded down. It was loose and made the trike twitchy and prone to violent steering wobble. My knees and arms have caught a bit of a suntan. Lots of hare about today. 26 miles.


A more mature section of the cycle path. The denser growth is better at blocking traffic noise from the main road which runs closely parallel just here.

8th 60F, 16C, blowing a gale, cloudless and sunny. I was being blown about all over the place. Which made it tiring which ever direction I was going in. Gusty and turbulent. Even with a tail wind it kept blowing me backwards.   Headset still too loose with steering shimmy if I let go of the bars. Only 17miles.

Three hours cleaning and adjusting Mr Higgins in the afternoon plus a 3 mile test ride. The Shimano, steel, triple chainwheel is a pig to clean even using car engine cleaner and assorted brushes. The rings are riveted together despite being detachable as a unit from the alloy cranks. Stripping an alloy triple is a (relative) piece of cake. The plated finish on the steel rings is very scruffy and the bare steel remains dark and unattractive compared to alloy rings.

9th 65-68F, 18-20C, blowy, full sun. My knees complained as I pulled away but I was soon able to forget about them. Despite a headwind I was doing about 16-18mph. Faster still on the way back with my shopping. I am beginning to get back my climbing power for the first time. Until now I haven't been feeling very strong. Nor confident enough to risk hurting my knees. So my average speeds haven't been very high at all. The lilac hedges are suddenly in flower. Still only 17 miles.

10th May 66-73F, 19-23C, breezy, bright with sunny periods but slowly clouding over. Going well again. Putting much more effort into it. Even getting out of the saddle on hills to try and use different muscles. 26 miles.

Alan Schmidt is going well (down under) at the Paracycling World Cup in T1 in Sidney. Alan won both the massed start and the time trial! Well done Alan! His hard training and careful preparation are providing superb results.


Beauty and the beast?

11th 60F, 15C, breezy, overcast with spots of rain. 20 miles successfully avoiding showers.


I thought this salad bowl of subtle variations on green was gorgeous. So I stopped to take some pictures. It is, or rather was, a kind of wild play area on a narrow lane leading out of a tiny, rural village. It has a tattered rope hanging over a drop beneath an ancient tree. Steeply inclined banks offer exciting bike rides for those with the wind in their hair. It might have been a sand and gravel quarry in the dim, distant past.

From a time when kids still knew how to play out of doors without ephemeral props. When the only real dangers lay in in the boundless imagination. Before everything had already been done to death on an artificial screen. When the roads and lanes were still empty, linear playgrounds. Full of magic and raised, excited voices. Competing for hyperbole against a constant background of deafening birdsong. That was back before we sold our children's souls in exchange for commercial, plastic tat. For cheap, instant gratification and the opiate fix of lurid, secondhand entertainment.


 Here's confirmation of my love for lush spring woods and winding country lanes. I'm reposting a missing picture but can't duplicate the missing text.

12th GOOGLE REALLY SCREWED ITS BLOGGER CUSTOMERS. WILL WE EVER SEE OUR BLOG POSTS AGAIN? BETTER ASK GOOGLE! 26 miles.

13th Still no posts for the 12th and still no access to write. I'd better back everything up before Google loses it all again. Blogger is not a free service. It is paid for with Google advertising. 28  miles?
  
14th  ACCESS AT LAST BUT STILL NO POSTS FOR THE 12th. 28miles?

15th 60F, 16C, very windy, sunny periods with occasional, very heavy showers. I thought I was pedalling into a storm when the sky went black up ahead. Though only a few drops hit me as it went north of me. Still no 12th May posts. I am now backing up my mileage chart as often as I can remember to. Only 12 miles today.

A red Newton

*
Ivan Haynes, the owner of this Newton trike has not only provided some superbly sharp images but also shared some YouTube videos.

WARNING! Please note that the image enlargements in this chapter are from 300kB up to 600kB. If you are on a slow internet connection please be advised that clicking on any image may result in a considerable delay. If you have to pay for your downloads then this is one more reason to avoid the enlargements. I normally set a size limit of 300kB per image in my blogs but wanted to do justice to the photography on these excellent images: 


General view showing unisex top tube arrangement and twin front wheels in the so-called "tadpole" configuration. As opposed to "delta" which has two rear wheels. The tetrahedral arrangement of front frame tubes ensures stiffness at the front end. The steeply sloping, top tube is continued as a further pair of stays to the rear wheel drop-outs. Very strong and stiff but with a weight penalty. In fact, this Newton is no lightweight according to its owner.

The emphasis on weight at the front might make it more difficult to bump it up over a pavement edge. But at least the wheels don't run into the backs of your legs when you walk it around.  (as does a delta)


View from behind the cockpit. The rider can clearly see where the front wheels are going. Making it easier to avoid potholes compared with a delta. The front axle bracing is well seen from this viewpoint.



Right side, front axle in close-up. Showing the Welsh head badge and Newton signature. Brake equaliser bell-cranks are seen on the extended head tube. The steering rods are clearly seen with ball joints at either end. These take care of the strange angles as the wheels move from lock to lock in both directions. Ackermann steering with the king pins pointing down at the centre of the tyre contact patch to avoid bump steer. Earlier tadpole makers used upright kingpins with disastrous results on high speed stability on rough surfaces.

The tadpole has a much wider turning circle than a delta. Not a problem in normal riding but a possible inconvenience in tight spaces. The delta can turn in its own length if necessary. With the Newton I'm thinking about the bars fixed at the ends of cycle paths. They form a very tight chicane to stop motorcycles and scooters from entering and causing high speed mayhem.


Rear view of front hub and widely splayed bracing tubes to ensure the axle stays aligned on the front of the supporting bicycle frame. The king pin housing employs bicycle head tube bearings neatly capped off. This should ensure very long life and no early redundancy due to lack of spare parts. This can be a serious factor with proprietary cycle parts. Many of the recumbent machines on the market at the moment will become so much scrap metal if their manufacturers should fold. Their designs incorporate unique parts made and used only by their makers. The Newton has wisely chosen the well trodden path of standard parts. So should have no real limit on its lifetime if treated reasonably kindly.


Front wheel and hub seen from the front of the machine. The slim rims need no braking surfaces. The wheels are quick release thanks to a sprung pin through the hollow axle. These large flange, Sturmey-Archer, drum brake hubs are popular on wheelchairs. I have a pair of these wheels in the 24" size just waiting for me to finish a project to build a similar tadpole trike. At present progress I may be too old and doddery to ride it when it is finished! 


The finish is a little "untidy" on some of the joints. Particularly in the bottom bracket area. This uses a lugged, bottom bracket shell. Goodness knows where this came from originally. Perhaps a rear tandem bottom bracket?  


A single rear brake probably provides a steadying influence on long descents. I have no idea if the S-A drum brakes are prone to heat fade as are car drum brakes. One owner complained about the lack of braking power with drum brakes. Newton now employ disk brakes on their trikes and conversions but as some extra expense.


The bottom bracket are showing duplicate tubes for the front axle braces. I suppose one should call them front axle stays. Their lateral dimensions must ensure that the rider's toes do not collide with them in normal use.

Ivan Haynes, the owner, tells me that it is relatively easy to lift the front wheels individually while riding or standing still. Even to corner as if on a bicycle if so desired. The front wheels are also rather easily locked under hard braking. While on a delta it is almost impossible to lock the single front wheel even braking hard on black ice. Though it is much easier to do so on loose gravel.

Now a couple of videos of the Ivan showing the truly remarkable stability of the tadpole arrangement. Or is it just his acrobatic skills? It would take considerable practice on a delta to be able to lift a wheel and keep it in the air. I have tried lifting a wheel to ride on two but do not enjoy the feeling at all. It feels very unsafe and unstable and rather unkind to the wheels. Ivan, the owner of the Newton, makes it look very easy indeed. He himself emphasises how stable the Newton is compared with his own delta trike.

I am most grateful to Ivan for sharing these excellent images and links to his videos.

Ivan's review of his Newton follows: Note: I have split some of his original paragraphs into smaller sections dealing with specific points about the Newton trike. His words remain unchanged. Just as they were communicated to me in a private email. He has given me permission to post it here.

"My experience with an upright tadpole trike, having bought one last year and ridden one for the first time last year is that it is much easier to ride than an upright delta. Over the years I have tried many experienced (two wheel) cyclists on a delta and found they cannot ride it, but now if I try them with the tadpole first, they can then “progress” onto a delta after a few minutes. It is much more stable through bends, seems to require less lean from the rider (hanging off) and you can get away with braking into corners.
 

So far I haven’t really noticed any pull to one side even though the brakes are not quite even. That might be because the front brakes are not very sharp, but it is still very easy to lock up one of the front wheels under braking. Normally on a good surface you will know how hard it is to lock up the front wheel of a bike or delta trike. On the tadpole they lock up surprisingly easily however good the surface and grip is.
 

When cornering it is very easy to go round a corner with either the inside wheel or outside wheel lifted. In fact you can lean the machine over into a corner just like a bicycle. This is a bit trickier on a delta. Either of the front wheels can be lifted very easily indeed, again much easier than on a delta as there is much less rider weight on the front wheels than the back wheels of the delta. When riding along the road a front wheel will often come up “of its own accord” or from going over a bump.
 

Some downsides of the tadpole are as follows; Weight, it is quite a heavy machine, I must weigh it so that I can let you know what it actually does weigh. With all the extra work for steering the front wheels, it is quite heavy at the front and overall I would say is heavier than an equivalent delta.
 

Steering lock is also a limiting factor. This is not something that matters or would be noticed in normal road riding, but it has very limited steering lock. You know how you can almost spin on the spot with a delta, the turning circle is much larger with the tadpole. The frame design is shaped so that the front wheels can turn, but eventually they will meet and the tyre will rub on the frame (inside wheel). When riding, before it hits the frame if you turn too sharply, the wheel will make contact with your foot as there is huge toe overlap. This as said before is not an issue with normal road riding, unless you want to do a u turn on a narrow road.
 

Another issue with the Newton trike is build quality. I don’t like to speak badly of a builder and I have only got the experience of my machine, I have not seen other Newtons up close, but the frame is a little rough in its construction. It seems to be arc welded rather than fully brazed and some tubes are joined (in the middle) in their length. Overall though it is still a nice machine, just a few touches here and there could make it really nice."

Trykit in Reynolds 953

*
Ivan Haynes, the owner of this superb Trykit delta trike in satin finish, Reynolds 953 stainless steel has kindly shared some images. I believe this was only the second trike ever made out of this exotic material. The workmanship is truly amazing. The craftsmanship that of the true artist. It weighs a mere 21lbs complete with 27 gears.

I am delighted to be able to show these images here. I knew the trike existed from Geoff Booker's Trykit website but I could hardly just borrow his images to post here. Those images which have appeared I have obtained permission for and relate to Geoff's excellent 2WD system.


General view showing carbon forks and wide ratio gears. Radial spoked front and cross spoked rear wheels. A neat, side entry brake is hidden behind the forks. Ideal for avoiding the brake cable colliding with the down tube on turns. Dual action, racing, brake/gear levers.


Rear view emphasising the shapely curves of the chain stays, cross bracing  and axle loops. The joints are flawless. The conical bearing housings are beautifully elegant. Small bosses are provided for a removable, rear rack. A Trykit 2WD system is fitted.


The gentle slope of the top tube is nicely understated. I was brought up on horizontal top tubes so probably have very outdated ideas about sloping tubes. Low top tubes do have very real advantages on a trike when tackling pavement ramps at an angle. With the amount of traffic about today it isn't always possible to line things up neatly and take ramps straight on.

The rear wheels rise suddenly and completely out of unison. Rocking the top tube and saddle fiercely from side to side between one's legs. It pays to lift off the saddle to avoid a very rough ride. The lower the top tube the less overall movement thanks to the smaller radius from the centre of the rear axle.

The superb finish on this trike should last indefinitely. The usual paint chips and wear and tear will never mar the finish over time. Reynolds 953 stainless steel is wonderfully light yet stiff. Though reported not to make for an uncomfortable ride. No doubt the carbon forks aid comfort over rough surfaces. What a superb machine! I am most grateful to the Ivan for sharing his good fortune in owning this Trykit.

Geoff Booker of Trykit is certainly offering some of the most sophisticated delta, upright trikes in the world. His workmanship is superb. He builds not only frame sets in a wide choice of tubing but also hubs, wheels, axles, 2WD systems and complete trikes.

More images of this mouth-wateringly beautiful trike can be seen on the Trykit website, with others, at:


Oddly this link only works in Chrome and IE on my computer. Firefox refuses to show many of the images on the Trykit website. Even describes the individual referring links as broken! I hope you have more luck with your browser.

I am most grateful to Ivan Haynes for sharing these images of his gorgeous trike.

Postscript: My own Higgins "Ultralight" weighs 31lbs when fitted with a lightweight saddle. To have a fully equipped trike fully 10lbs lighter than one built with Reynolds 531 tubing is absolutely phenomenal!

PPS: Out of interest I weighed Mr Higgins today in full formal dress. Complete with shopping bag, lightweight waterproofs, rack and tool kit. It came to 38.5lbs or 17.5kilos! I often carry 10lbs of shopping uphill and down on top of that. It's no wonder I can't keep up with these young chaps who are out training on their lightweight racing bikes. :-)
