Thunderbug Trike (yet another project)

With a fair bit of trepidation, following my abject failure to finish the Midge project, I have decided to announce my latest and probably most absurd project to date (probably not as absurd as the Mad Max Volvo Pickup I was building which ended when I broke my back running out of talent whilst mountain biking on Cannock Chase)IMG_0048

So without further ado, here is the future of urban personal transportation, The Thunderbug Trike

All right I will be the first to admit it looks like a box with three wheels magically suspect in a vertical position but it is a start.

I have been tinkering with the idea of building a trike for a number of years but was always put off by the fact that using steel would make the trike weigh around 40lb and that aluminium was just too difficult to work with without specialist equipment. I have also been tinkering with the idea of using bamboo as a frame material as I have the tools to work with wood (or grass) and just about enough skill to get me through. Some may remember the plywood recumbent me and Connor built two years ago whilst I was convalescing from my road accident. Indeed the seat and rear wheel have been salvaged from the back of the shed as temporary props for the Trike.

Whilst the bike made very interesting riding, it did prove that wood would work and that I would be able to ride a bike again as up to having my second operation riding an upright bike was out of the question.

So fast forward to the present and the urge to have a go at a trike had reached the top of the pile of things I wanted to try and build. In the intervening years it appears that composite materials are now readily available in the home user environment. There is a wealth of information out there and a number of suppliers happy to provide no minimum quantities to enthusiastic amateurs. There is also a growing number of people building bamboo bikes and whilst the knowledge required is generally more guarded by those in the know, probably because there is an abundant number of hipsters willing to part with loads of money for their ‘boo bikes.

After researching what is out there and buying a number of books (including the excellent “The Cycling Zoo” by Steve Nurse and “Bicycle design” by Mike Burrows I decided on doing away with the typical bike frame in favour of a monocoque chassis, after all in my mind a trike has more in common with a car (or a three wheeler) than a bike and with the use of composites it made sense to build a monocoque utilising the inherent strength of the materials, the weight saving benefits and the simplification of the build by bolting the components to the tub. The more I thought about it the more it made sense and would allow me to dabble with new skill sets.

The design has come along and will be an amalgamation of natural and man made fibres, bamboo for the front wishbones, pedal boom, rear arms and seat, carbon fibre for the tub and supports, aluminium for the brackets and links. I have incorporated four link shock absorption on the rear ( I wouldn’t dare call it suspension but hopefully it will take the pain of the bumps away) and I have ovalised the bamboo to utilise more substantial poles without adding to the bulkiness on the lines. I haven’t seen this done before and there is probably a good reason for it but naivety is the mother of invention, probably.

So far I have manufactured the tub from plywood, the plan is to manufacture the rest of the parts onto the plywood model making any alterations required until it all looks right, then to use it as a plug for a mold to form a fibreglass chassis. This chassis will be used on the road to see what breaks and what doesn’t work before finally committing the design to carbon fibre. The bamboo parts will be well tested and if they prove satisfactory will make it onto the final product, if they don’t they will be replaced by readily available carbon fibre tube but that is all months down the line.

This afternoon was the first opportunity to mount things in situ on the jig (offcut chipboard) and already I like how it looks although I have let to puzzle out how to mount the front boom and wishbones in the narrow space available, it looked wider in Sketchup than it is in reality.

The build costs so far …. edit… I was going to put the build costs down but I just scared myself totting it up. I will keep a record and decide if I dare report it as the project develops..

Sorry is the hardest word to say

Two weeks ago I was involved in an incident whilst cycling home from work. It was way to close for my liking and forced me to act to avoid a collision with a single decker bus operated by National Express on the 997 route. The Driver was wholly in the wrong after completely misjudging the situation. He chose to overtake me with the full intention of immediately pulling in to the kerb to allow passengers to board. There was also standing traffic at the roundabout ahead and oncoming traffic approaching at a point where the road narrows. I suppose if you are going to try the impossible you should be applauded for your efforts and this chap deserved an ovation.
Due to the conditions mentioned above he wasn’t able to make a getaway and I drew along side his cab to express my dissatisfaction. To be honest I would have been happy with an apology there and then, we are human, none of us are perfect. ” Sorry mate ” would have made things fine, hopefully we would have all learned a lesson ( obviously when I said  we I meant him)
Instead of “Sorry Mate ”  I got told to “Fuck Off”, I then got treated to further abuse using the medium of mime.  I recorded the event which is very crudely edited here link The full version remains in case anyone wanted it.
To be fair my first reaction to this would have put me in the wrong, so my second reaction was to complain to his company. I believed that this would help the driver gain an understanding of what it like to be assaulted with a deadly weapon and that arrogance is a very unlikeable character trait. I also believed the person best placed to deliver these valuable lessons should be the ones who paid his wages.
Sadly this appears not to be the case. There will be no apology, I will never discover if the 997 bus route is a little safer or that temerity is no longer a requirement for operating a psv. I don’t know if I am a marked man in an “On the buses” style with every bus overtake  being accompanied with a fist shake and a wail of “I’ll get you Biker” 
I finally received a reply from National Express complaints department after numerous emails and after throwing my Twitter toys out of the pram last night.
It appears the complaints department is very busy and is running days behind. I was informed I wouldn’t be told of the outcome to protect the driver but they did at least know who he was. So let’s get this straight, his incompetence nearly caused an accident, his reaction was to abuse me and I don’t get my apology to protect him. That is utter bollocks. I don’t need his name, although he is licensed and should be prepared to state both name and number when requested. I just wanted an apology from him and an undertaking from the company that he would be retrained, briefed as required to bring his standards up to those expected in his position.
I don’t think I am unreasonable, after all I saved him from attending an inquiry or making statements to the Police and all that nasty stuff with the Press and the years of counselling. Mind you I am only a cyclist, I don’t count. I suppose he and his Manager had a good laugh at my expense whilst having a swift half in the pub before the afternoon school run.
As far as my complaint I hope it provided some entertainment as they tried a few three pointers from the printer to the bin.
I have learned a lesson here, don’t bother complaining to National Express just go straight to social media. Public image is everything. In fact don’t go straight to Twitter just ring the Police, although in my experience their system was based on the National Express set up, but at least the Police apologise when necessary.
