April 1, 201610 yr Still in the test stage this spring drive is now running well. The drive is taken to the inner chainwheel. Power is initially achieved by winding up the three springs with the key. The springs are rewound when going downhill so almost 100% power recovery. Tests have shown this wind up to work quite well. The cam seen in the centre gives 12 stages of power. Very quiet in operation with only a soft tick which you can barely hear when talking. Bit more time needed to tidy things up. With a carbon fibre case and the key gold plated it should look quite striking. Any comments please feel free to chime in.
April 1, 201610 yr It would be interesting to know the true efficiency. There have been many designs for spring driving bikes previously of course, there's one such design on this link. .
April 1, 201610 yr Tests have shown this wind up to work quite well. Perhaps this phrase is the key to the posting?

In which case I have designed a method for extracting speeds up to, and including, ludicrous speed. It's based the badass "dongle" Essentially it is a device containing two small mirrors. The mirrors go either side of 3 springs. So if you look into either mirror there are now infinite springs stretching away Infinite springs ergo infinite power I'm calling it the "Goodrear Mangle" Kickstarter coming soon
April 1, 201610 yr Be careful that chain doesn`t do a Parry Jones on you ie wrapped around your neck causing strangulation, as might have happened to the Driver of Babs at Pendine in 1927 . This is disputed now and they think the upturned racing car might have been the cause . In any event don`t fall off the contraption or you won`t see the Summer of 2016 !
April 1, 201610 yr Caught me! Merry April to you. (By the way, your Gran wants her long case clock back)

April 1, 201610 yr Interesting,What kind of bike is that in the picture? I'm pretty sure is a 'Beast' model, from a company called Mythical. Been around for a long time.
April 1, 201610 yr I'm pretty sure is a 'Beast' model, from a company called Mythical. Been around for a long time. Yes it was a good April Fool but I am genuinely interested as it looks unusual and a quality build
April 1, 201610 yr Author Answers in order. Flecc- that link's a wind up Dave .-The wolf of Badenoch is barking up the right tree Timid tom,- well spotted-other clues, tick, talk, time, striking, chime. Kristin,-Speed on this one is in Knots. So MPH law does not apply Roadie Roger,- You leave Babs out of this, very nice girl before I met her. Mike K - It's a Westminster not a Longcase Haggis- It's a Xootr Swift ,google for spec Alan Q, Modelled on the Watkinson Dingbat. Earlier than the beast.
April 1, 201610 yr Answers in order. Flecc- that link's a wind up Yes, good one. I don't usually get caught by these but this time I was since there's been a number of spring drive bikes I knew of in the past, some of them really eccentric. Yours was unintentionally leaning towards practical! .
April 1, 201610 yr Author Glad you enjoyed it. I done one a couple of years back on a watch forum using a faked up Vacheron Constantin watch. Fooled lots of experts ,I even got mails from Geneva asking for more details . Brilliant laugh.

Now that really was stuffed with simple clues! .
