Aero Garbage Wind Resistant a lie

[novocaine]

Mine is still in the loft waiting for me to have the space to build it again. I have managed to not cannibalism it for parts so far.

I have had a few 2 wheel recumbents too including a king cycle, a flevobike, and a lwb number whose builder escapes me.
2 wheelers are no good with steeper than 1:10 local uphill gradients - you need more speed to maintain comfortable balance than an upright bike, which can be a struggle if you can't stand on the pedals.

The flevo was like play-wrestling with a drunken lunatic - fascinating but dangerous.



That difficult point where steering flips to counter-steering is almost undetectable, with life-threatening consequences.

The, er, steering pivot is there under your perineum.

no argument from me, but I live in Cheshire, soooooo

you can see in the video that it's a bit twitchy at times, mainly down to the steering arrangement. I want to go over to above seat steering at some point, to see if a tiller helps with it. I found that on steeper climbs you could push back against the seat to get you up them, but it's not as easy as on a normal bike.

they don't fit in a bike rack very well

It looks like its going 200mph even while it's sitting still!
Oh, it actually is going 200 while sitting still!

The Rolling Road helps eliminate crosswind, i imagine

now you see, I read that as rolling top speed, not rolling road. Like towed to speed then shielded, not sat on a trainer.

Beauty is in the eye of the beholder and all. The Diamondback Andean. Possibly the first time this has ever graced Retrobike.

Did anyone discuss how much additional benefit there is to aero in a 20mph head wind?

Bet that’s fun in crosswinds.

Motor Paced is different.
Current record iirc

This bike doesn't need to be very aero either,
but the rider needs full on mc-racing crash protection!

This is probably why he's slower than...

You can ride this in lycra, but if you did fall off, you'd want to keep all parts of your anatomy away from the spinning rollers etc

Tbh the motor Paced ride could have gone faster with disc wheels, but the roller dude could've gone faster with a body position designed for power output rather than frontal surface area.

Give us these guys, the kit, an Allen key and a roll of gaffer tape, and we could beat both records.

if they are being towed why bother with cranks etc, its just a guy on a linear 2 wheeled trailer at high speed
