Nah, Hoeha's bike is just cooler. :mrgreen:

It is kind-of weird. They both handle better than the other. The bikes that have more of a rear fork handle better with the rear steer tube angled toward the rear axle while the bikes with the steer tube more in the middle of the bike handle better with the tube angled more toward the crank. Both setups allow the weight of the rider and the geometry of the bike to sort-of self center. I prefer the rear fork style frames because they are easier to wheelie. Both styles handle well, just differently.

The placement of the pivot in relation to the rear hub isn't important like bikebuilder says The further back you get the seat and your body weight the easier it is to wheelie... however the angle of the rear pivot is very important and dictates to some degree what the bike will be able to do. The original swing bikes with the rear pivot tipped forward actually tip the seat and handlebars together when you swing the front end out. The rear facing pivot (parallel to the front steer tube) almost tips the seat and bars away from each other. As far as handling goes... the rear facing pivot is great for cruising and carving turns. It feels like your on skis carving from edge to edge! The forward facing pivot gives me much more control for tricks. It's all personal preference but try out both they are both really fun and eye catching.

my second attempt





Nice Swing bike, but I see a problem. Yours like mine will bend at the top of the back head set. You need a brace to prevent to bending back to the seat post. I put a stem in the head tube and another around the seat post, twisting them 90* from each other. Ive remodded 2 of mine and they work fine. Will take a pic of what I did in a bit.

Technically it is the position of the rear steer tube in relation to the frame and crank that is important; not the rear hub.

I don't want to pick a fight, but I have experimented with this. I experimented with one with the steer tube in the middle facing forward. It handled like crap. Putting pressure on the pedals would cause the crank to push out to the sides and toward the ground. I also tried one with the rear steer tube above the rear wheel tipped back parallel to the front steer tube. The pedals and crank flopped side to side and the pressure from pedaling would only add to the side to side flop as you would push on one side and then the other. Just holding these two reversed designs I tried upright you could feel the bikes were unstable.

If this doesn't make sense to you, go ahead and try it. It is at least entertaining. I am only trying to prevent headache and frustration.

Yes, sinner, yours would handle fine.

If you hold on to the handle bars with one hand and the seat with the other, twisting the seat side to side, your pedals should swing with the seat and at the same time rise. This is what I am trying to explain with the different angles. If you have have a middle head tube pointed toward the rear you will get the opposite effect. The same goes for having a rear head tube parallel to the front. your pedals will fall as you swing side to side. You want the pedals to rise when leaning or turning to maintain your ground clearance. Otherwise you will end up on the ground tied up in a pile of bike parts.

I think this thread is supposed to be a gallery thread, not a discussion. Can we move the comments to another thread? Maybe a swingbike geometry thread.

Just a thought.
