Wisper Video

Hi Guys

I thought you may enjoy these short videos sent to me by Anthony Clyde or Australasian Manager who does a lot of our R and D work. He was testing our new batteries on his test bike, a 2007 905.

They are simple hand held camera videos but I think they demonstrate the joys of e bike riding beautifully!

Up a very steep hill and overtaking Mr Lycra whilst whistling a happy song!

Down again (the man's crazy!)

Is it me but does the air look clearer in NZ?

Here's another from NZ.

The NZ promo video unfortunately with last years bikes.

All the best

David

Cool vids, NZ looks great reminds me of the passes here in the Lake District, obviously without the great weather

Thanks David, great countryside, enough to sicken any inner city commuter!

That Mr Lycra in the first video is going to destroy his knees straining uphill at that very low cadence. He'll regret it when the arthritis gets him prematurely in later years. Why can't people use their gears, there's been enough warnings on this over the years in cycling circles?

The look on Mr. Lycra's face was a scream, I nearly fell out of my chair I laughed so hard.

Vikki.

pardon my ignorance, what do you mean by low cadence results in athritis? Low cadence does this mean when you change the gears and it is very hard to cycle? What is the best cadence for no athritis

I am always make pedaling harder downhill, but uphill the gears I make them loose and easy to pedal

You've got it exactly the right way, change down to spin the pedals faster and make climbing easier.

The principle is simple. If a hill climb with 100 turns of the pedals needs X unit of work on each pedal stroke, changing down and using 200 turns of the pedals for that climb halves the pressure on the knee joints at each stroke. The pressures aren't cumulative, it's just important that a pressure on any stroke doesn't exceed the strength of the knee joint cartilage and bursa and damage them, allowing damaging bone to bone contact.

What that cyclist was doing in that video was very foolish, exerting a huge pressure on each stroke to make the climb. If he had no more gears to change down to, it would have been better to walk, since he was at walking pace anyway.

The recognised ideal cadence for sport cyclists is considered to be about 90 revs per minute, both for efficiency and minimum damage. That's too fast for many day to day cyclists, but keeping over 40 cadence is wise, preferably increasing that to a higher rate for uphill effort.

Thanks for the link to the videos...most enjoyable!


The last video shows the very functional poly-carbonate chainguard fitted to the City model.

Would it be possible to purchase these for retro-fitting to existing 905's, I really would like to throw away my trouser clips.

All the best

The air is absolutely cleaner in NZ. I don't know about Britain but here in Korea a 20km visibility through haze is pretty exceptional. In NZ it's possible to see much much further. It's possible to see mt Ruapehu from Mt Taranaki (130km) and apparently Mt Taranaki can be viewed from the South Island on an exceptional day. I once went to the viewing spot as a boy but it was a bit hazy.

From my parents house in Nelson we quite routinely look out to see snow on the Arthur ranges 70km away. That's routine, not exceptional.

I'm not sure what it's like in Britain, but one could never do this in South Korea.

Haha, that's brilliant!!!

...and what great roads too

Hi Bob

Yes no problem, send me your email address and I will get Norman to sort one out with you.

All the best

Pleased you liked them

Thanks Phil I thought they were brilliant!

It was Anthony's expressions of glee that I found most amusing!

All the best

I can vouch for that chain guard it has saved many of suites (even if it's not what all the cool kids have )
