    Just a word of warning. Keep an eye on those sprint braces. If they're aluminum, they could end up breaking where they're crimped and bent. Or they might go years without problems. Elegant solution, though. If the Al doesn't hold up, you can always replace it with 3/8" stainless supply tubing.

    Ok, the bike is ridable. Just as I thought, I can actually turn. Tearing around streets is pretty easy, but tight turns are obviously a bit of a prob. I can turn 360 degrees at the cul-de-sac at the end of the street with out too much of a problem. It's a fast bike, and takes the hills really easily, which was kind of a nice suprise. The steering column has a bit too much flex in it for me, so I'm going to try some steel ape hanger handlebars and tilt them back. We'll see. There's video of my 2nd ride posted on youtube here:

    Glad to see you have a rideable 'bent

    It looks like you will have a lot of fun. Congratulations on building a very long wheel base bike that you can ride easily.

    THE FINISHED BIKE

    Here are the photos of my finished chopper/recumbent bike. I rode it this evening for about a mile and it rides really nice. It's really hilly here in Las Vegas and I'm exercising muscles that I've never used before, but other than that, it's great! Going down hills is really fun and it surprisingly climbs pretty well. I need to make some small adjustments on the rear dérailleur and will probably invest in some ape hanger handle bars for the leverage later on, but I can actually manage it pretty well in the current configuration. It does turn pretty wide, but I can turn a lot tighter than I thought I would.










    I'll see you guys on the road!

    Nice, clean JOB !!!

    How is the handling of this bike? Can you write down characteristic of steering? (Headtube angle, trail...) You have a HUGE trail(normal and mechanical) which translates also to big wheel flop.

    I try to make an semi-low recumbent with headtube of 45 degrees angle. I want to have drive mechanism somewhat similar to that of Thys rowingbike(Rowingbike). I had even build functional model without drive but with changeable headtube angle and changeable trail, to examine steering and stability properties. It seems like 80 mm of trail behaves best. Wheel flop is around 40 mm and because of lower wheel load it is manageable. I'm able to ride on that model even at small speeds, nearly to standstill. I can make curve of about 4m diameter.But there is issue of higher speeds. I can't try speeds higher than about 15-20 km/h. I have read that such high trail(mechanical trail is calculated to be 60mm) will make bike too stable at higher speeds... I tried lower trails... down to zero Scary Can you write me your experiences?
