Just logged on to tell you lot and put up the links but I see Stuart has beaten me to it.
I came out of the bank to find the ABC guy waiting for me. ABC studio is just over the road so I could hardly refuse. We wangled the mango into the studio, had a bit of a chat and then did the interview pretty much off the top of the head.
It aired next morning and at about 9.00 am the TV mob rang.
By the time they got here it was raining and cold standing round. Hence the top, Paul. I didn't need to remove it for a couple of runs up and down the street between the showers.
Edit. Oh you meant the flouro in the photo. Slow brain here. Put that on out of the velo. As you say not needed when riding.
There was no prior discussion with the reporter so I had no idea what she would ask. The cameraman took quite a bit of video and I see they cut and swapped around to fit. Not too bad a job for the TV news.
I hope that it helps with promoting velos.
Today we went out for a ride of about 20 km. Wife on trike with dog in trailer and me with the Mango. By the number of waves and toots quite a lot of people had seen the segment.
On the way home I passed a group of young indiginous guys who asked to take a photo. I had to act quickly to stop the guy with the half empty wine bottle who went to sit on the front. It was actually starting to buckle. He got a serve from his mate who told him it was only thin fibreglass. My fault I should have pointed out that it was fragile up front.
I moved the chain return tube from under the pulley to the side today and it more than halved the chain noise.
BTW Rhubarb and BSMUG. I don't come cheap.

If Baalzamon gets a Mango and moves down here we will be Albany Sinner Mango Group ASMUG (As Smug).

Here's the first leg of a great ride from Harry Leiben who works for Sinner Bikes (makers of the Mango):il padrone wrote: .... My brother rides a Rotovelo and I am surprised by the distances he rides, seemingly so easily.....
http://connect.garmin.com/page/activity ... id=1524580
There and back he rode over 400kms in a day. Not bad for a 50 year old. No doubt the reclined position helps out the back and joints over longer distances.
PS Check out the elevation chart though, unbelievable. I have more elevation on my 12km commute

There is a YouTube video I watched with Harry and Arjen I think riding some considerable distance to make a delivery.
Here are the vids.
Go to YouTube to read the details.
Even on ROAM and in the Rockies and all they were averaging insane distances. Can't recall if it was 200km or 200 miles per day.
I'm not fast but if I take it easy I think I'd be able to comfortably ride all day and in almost any weather. I can't say that for any of my other bikes.

You'll get very good at telling people how fragile the front is quickly, before they get too close. I must say, I really dislike people that need to look at my Mango with their fingers. You'll get a lot of that. It is particularly bad when it is dirty. Fingers rubbed on the dirty gelcoat leaves tiny scratches which have to be polished out - same with the hood's visor. Unsupervised children are the worst!
The interview went well but I can't help get the feeling that they were partly taking the piss to be honest, particularly the ABC interview.
Also, I'm a little perplexed that you say you were 'led to believe' the Mango would be faster, John, as you mentioned in the interview. Had you entered your power data into the speed calculator before? When punching the numbers into the speed & power calculator, my actaul cruising speed is spot on with the predicted speed:
http://www.hembrow.eu/personal/kreuzotter/espeed.htm
I'm 70kg, 173cm tall and can output a sustained ~200W below my anaerobic threshold for many hours. I can output much more for anaerobic sprints but this results in an oxygen debt that needs to be repaid so that's not really relevant. This gives me an on-the-flat cruising speed of 43km/h which is precisely what I comfortably cruise at.
The figures are also correct when I substitute the Mango Sport for my road bike (on the drops) - I cruise at about 34km/h on it (aerobic).

Yes I'd agree with the comments on taking the proverbial. I think it goes with the territory. Particularly with those breakfast programmes. The interviewer Andrew was in fact very interested in the mango and we had quite a talk about it afterwards. Had he not been so tall I might have let him try it out.
When it comes to the speed I have played with the calculator but I have no real idea of my power only to say it is not great or at least not sustainable. I can just hit 30 on the flat but cant maintain it for more than probably 30 seconds.
From my reading I'd decided I'd be somewhat faster than I currently manage. in fact I am a bit and that may improve. I'd love to have the chance to try one of those power meter devices and see what I in fact can produce.
More to the point is that in the interview you are having to respond quickly and off the top of your head so you don't always manage to say what you intend. I've done quite a few interviews over the years both for TV and radio and although I'm used to it it never seems to get easier.

Riding to town and back the other day there was a fairly strong wind. Going it was more or less a quartering tail wind from the left and returning a quartering head wind from the right.
Going to town is generally down hill whereas returning is more up.
On the way in I averaged around 22.5 and returning the average went up to 24.1 by the time I got back to my turn off on the highway.
Note that the average improved even though the return is more up hill.
Normally I'm a lot slower than that on this ride.
The only thing I can put the improvement down to is that there was some sort of sail effect a bit like tacking a yacht assisting me.

Does not make much sense. Yachts run much faster on a broad reach downwind than they can close-hauled into it.John Lewis wrote:The only thing I can put the improvement down to is that there was some sort of sail effect a bit like tacking a yacht assisting me.
Should be the same for velomobiles

That's why I can't figure it out.
There was obviously something at work though and I don't know what.

I used to sail a 12 foot Surfcat and during light breezes I found tensioning up the battens in the sail generated more lift by giving the sail more of an aerofoil shape.

I reckon it is more likely to be some sort of physical/psychological difference eg. you were more warmed up for the home run; or you were expecting a hard push homewards so rode it that much harder without realising.

Yes, the flat bottom of the Mango makes it slightly aerfoil in side view (and it does have holes in it). But I was talking about the plan view. An aerofoil in side view would give lift - not necessarily something that would produce higher speed.Joeblake wrote:Just looking at this photo it seems to me that with the flat bottom and curved top the shell vaguely resembles an aerofoil shape.
Has that canopy been Photoshopped on? And the front of the shell?

I sent the picture of mine to mate in Brisbane. He commented that he thought the hood was ugly. Indeed he thinks the Mango is too.
Anyway he sent me this GIMP job of mine to show me how he thought it ought to look.

Yes, it is a shame. I certainly would have expected more from the ABC but then they don't have a very good track record with their television breakfast show and I simply cannot stand our local ABC radio breakfast talking head.
30km/h on the flat would equate to about 100W at the crank. 50W at the crank will give you roughly a cruising speed on the flat (no wind) of 19km/h. A colleague of mine does does pre-operative anaerobic threshold testing and I was able to go on her machine for a bit of fun. At least I know the figures are accurate. Many devices for measuring power output are not very accurate. I hear stories of riders who claim to have a power output (aerobic) of 500W or more... that's just nonsense. Lance Armstrong at his peak had a sustained output below his AT of 370W and we was shoulders above the competition!John Lewis wrote:When it comes to the speed I have played with the calculator but I have no real idea of my power only to say it is not great or at least not sustainable.

I'm pretty happy with 200-250W!
Yes, I've done a few too. Even if you think you've said everything clearly it can be very easily edited to sound different. I'm slowly learning from my mistakes. My interviews have been with respect to mandatory bicycle helmet laws, not the Mango. In fact, I don't think anyone is particularly interested in it here in Brisbane. I'm sure they think I'm either mad or disabled.John Lewis wrote:More to the point is that in the interview you are having to respond quickly and off the top of your head so you don't always manage to say what you intend.
