I'm Seriously Impressed. Way to go.

How much are you going to charge for the production model? 🙂

Class act. I was quite proud of the Dutch Speed Bike but doing it from
scratch is in a different league.

If anyone is daft enough to ride something that I built, then I don't
think I'd have the heart to charge much.

New skills required though:

Pipe bending (To build custom handlebars 'cos mine could do with longer
bar ends, but then I'd not get the shifter to work.)
Jig building (The next challenge. The frame alignment is well within
tolerance - possibly better than some cheap bikes - but it'd be nice to
get it closer.

While my welding is good enough, it'd be nice if it was much better.

Seriously though, if I can build a jig, I guess I could make a frame +
bottom bracket kit for any interested parties! <thinks>

Thanks. I'd still be interested in taking a look at one of the Dutch
Speed kits at some point.

Indeed, 'nuff respect Jon! I'll stick to throwing money at the problem
as my engineering skills don't get much beyond putting up shelves...

But if you want to play, I have a welder ...

They are about to scrap some abandoned bikes from the bike sheds so I could
get the second half of the prototandem ..

I'm having thoughts of doing a mixed up and down one now.. On to the drawing
board..

There's a picture of a rather nifty wooden one in the latest VeloVision...

I'm seriously impressed!

Maybe see some of you in York on Saturday. In Guy's (potential) absence
(Splitter!) where will we meet?

I'd love to have made it, but we have a really hectic schedule of
Other Stuff (TM) this weekend. :-(

Damn you, Jon Senior, you're giving me Ideas!

PS: If it's not a terribly rude question, what does your frame weigh?
Is your bottom bracket attachment the same as on the Dutch Speed Bike?

I haven't weighed it yet, but it's "not too heavy". My gut feeling is=20
that it weighs in at less than the Street Machine but obviously doesn't=20
have the bonus of rear suspension.

The interesting thing is that the weight appears to be distributed about=20
50:50. The CoG is high enough to mean that a solid brake with the front=20
wheel can lift the rear of the bike (There's not much danger of it doing=20
that once all the camping gear is on it though ;-)).

The bottom bracket attachment is frankly [censored] and in need of revision.=20
It's based on the same design but uses a complete shell and two 2mm=20
(thus flexible) steel plates with four bolt holes. The problem is that=20
the plates have to be distorted a lot before it generates enough=20
clamping force to resist the force of the pedals.

I plan to use our milling machine (and a jig) to make a steel version of=20
the beautiful machined aluminium jobbie that Dutch Speed provide.

The basic principle is however, the same.

And with regard to cost (Which I forgot to mention) back of an envelope=20
maths suggests a figure between =A3300 & =A3350. Probably nearer the latter=
=20
once I've sorted out a new front wheel!

Wot 'e said.

I designed a bent about 5 or 6 years ago (modelled on the Kingcycle),
but I decided that by the time I'd acquired the necessary skills and
bought materials and made all the mistakes that I was bound to make and
bought more materials, it'd probably be cheaper just to buy one.

I'm always seriously impressed when someone builds their own bike from
scratch, especially when they get it quite as right on the first attempt
as Jon seems to have done.
