Well I am very happy to hear about somebody interested in FWD and recumbent bikes. I like them very much and as I never got a chance to try one, I have already...

I have not heard that at all, and would not believe it to be correct. I'd say the flevoracer I have is actually much easier to control at speed then at slower...
I have riden in mine downhill maybe at that speed, one thing I can tell is that it is stable but you nead lots of concentration to stay on the line and of...

I came off a mountain in Vermont and had to brake a bit to hold it to 40 mph, roughly 64 kph. It was eerily stable, almost too stable, smooth as could be....

This pedaling strategy works, legs loose and at the ready for adjustments, and you can even do it pedaling backwards!...

... After more than 15 (?) years with 20" Flevo Bikes I can tell you that no pedaling or such is needed to stabilise downhill. After a few high-speed events...
That would be a good option. The 650 wheels are fine on a flevoracer, and the bike is still quite fast. I have one with 650 wheels. A higher angle headtube...
Thanks. I see that Wikipedia states: Roadster bicycles traditionally have a fairly slack seat-tube and head-tube angle of about 66 or 67 degrees, which...

Yes. The flevo is not the same as a standup. Steering is effected by pedal pressure. If you are very strong and pedaling slow, the power of your legs will move...
... And even more: The thought extension of the steering axle has to run through the rider's hip. This is perfectly matched by the Flevobike design. If you...
"The steeper headtube was always better. The caveat being that the trail must be kept at around 13-15 cm." Thanks for that advice. Won't the pedal steering...

Yes I agree. It IS the function of the rider to compensate for the steering torque. I was thinking (dreaming, really... ) of a mechanism that could be part of ...
