back on two wheels

OK, _you_ write something similarly technical in Japanese...

Ah; you sell cycle bits?

 

this is true. not all of 'em, though, just a subset

http://www.roman-road.co.uk if you want a look.

 

I'd GAMI, one who could write good idiomatic Japanese. It's not that bad,
anyway, and the oddities don't prevent it from being understood. But in a
commercial enterprise, I'd want to avoid anything that distracted my
audience from the message.

 

I guess that's true. I'm used to dealing with high-turn
high-inductance DC magnets, like ones that take a minimum of 26 minutes
(preferably 40) to ramp down from 75 A to zero (5.1-0 T) if you don't want
the winding to go supercritical and "quench", boiling off all the coolant
instantaneously. I suppose SC motors need coils with much less
self-inductance and have to rely on back-EMF to limit current densities
below the critical value. Not sure how they'd handle the high-current
start-up phase though -- some sort of ballast coil/resistor perhaps?
Or, as in the original paper cited, use a fixed field from SC magnets
and (warm) copper coils for the rotating bit.

I like the trike wotsit.

What would you charge for building a 26" wheel with customer-supplied SA
hub, stainless spokes and strong rim suitable for a heavy rider? Tyre to
be 1.5" road, suitable for general purpose.

 

Yep. I just changed the sticker on the motor to say 200w )

Rules like those are made up by flatlander fools dahn sarf. If you want to
use an electric bike in hilly country, you need more than 200w. Especially
if you are 6'8" and weigh 16 1/2 stones.

It pulls along at around 18mph on the flat with easy pedalling and does
around 12mph up fairly steep hills. So it's not grossly beyond the
intention of the law.

The twistgrip snaps back to the off position

It's well under the weight limit.

Two out of three ain't bad. ;-)

 

What, there ain't no way you're ever going to love me? I won't be sad...

He's a bit of a bloater, isn't he

 

The 15 mph is electric-only, anyway. You're allowed to supply extra go via
the pedals, I think.

indeed. looks a useful bit of kit. been thinking about electric-assist for
Father's trike, seeing as how he's not as young nor as fit as he was.

 

nah, lightweight.

 

ATB-size wheel? do you want a quote for a tyre as well?

 

May as well; all in one, it saves me farting about locally and I'd be
ordering in a tyre from outside anyway. Oh, include p&p to Ireland.

My email addy works.

 

Trikes can carry more batteries

The kits RRP is £325

I got mine for £200

The seller doesn't seem to realise that the motors are in the wheels on this
item. may suit your dads trike for an all wheel drive diy job?

ebay item 270060318952

 

I think that's the kind that drives the front wheel, which has been nicked.

 

Big looking hubs on the rear wheels then. Quite a few of that type do have
the motors in the rear. The battery was housed behind the seat. Pity that's
gone.

 

I met one of your machines for the first time today. Conversion on a
Scott bicycle, belongs to a senile delinquent called Alan from Essex.

 

coo. He's the bloke who's stone deaf, ISTR?

That's a recent one and the Scott was a PITA to make it for, all
non-standard oversize tubing. But it came out OK in the end.

Austin Shackles. www.ddol-las.net my opinions are just that
Once, when the secrets of science were the jealously guarded property of
a small priesthood, the common man had no hope of mastering their arcane
complexities. Years of study in musty classrooms were prerequisite to
obtaining even a dim, incoherent knowledge of science.
Today, all that has changed: a dim, incoherent knowledge of science is
available to anyone. - Tom Weller, Science Made Stupid, 1986

 

It certainly looked good. He didn't let me HAG so I can't vouch for how
well it rides.
