Excellent!!! Keep going and post the finished boyke :) Question. What did you use to paint the syrofoam to make it water tight ?
Come up with something to attach to pedals that would work like a paddle to catch the water. Great idea!
Great idea, and if you just modify the rear mudflap, and add a chain set, like those for Snow driving, but with small paddles, you can actually pedal you way!Some kind of rudder will be needed, too...
It's a Tyre chain set, of course.
Speaking as a complete noob, what if propellors were fitted about where the 'ver' is painted, on both sides of the bike, with a gear system running down to the bottom of the pontoons, so that when they're lowered, the system connects to the sides of the tyre? The props might need protection, like the railings on quadcopters provide.I know, this would mean reduced clearance and greater risk of snagging, but for elegant (I think, anyway) propulsion...There's another potential benefit. If clearance is going to be reduced at the back anyway, fins, around six inches long, could be put on the front pontoons, at around the same height,so that when lowered, they would provide steering.Again, I'm no expert, and there are probably pitfalls I haven't considered, but it's just a thought. - TrollhunterX
OH..MY...GOD! I amnot sure what I liked more, the idea or the video! Doesn't matter, I totally enjoyed myself onboth accounts! The idea was great andnot over-engineered. Your craftsmanship and ability to incorporate readilyavailable materials is MacGyver 2.0! Keep up the good work! - benm3
The propulsion system is still a bit sketchy I see :) - NicB17
You need a 'daggar boards' for the front pontoons - or at least a fin, like you'd find on the back of a surf board. Otherwise your front wheel will drift sideways. Lastly, just like folks put chains on snow tires in the Winter for traction, I'm sure you put something similar on your rear tires that have small fins, like you'd find on riverboat paddles (or paddle boats) Lastly, if you wanted a challenge, rig up a gear wheel that uses the friction of the rear tire to run a propeller on the back. If you did that, you would not need to keep the rear tire in the water. Or you could do both the chain (paddle fins) and propeller. Inflatable innertubes might be another good addition to the outside of the pontoons. And lastly for ocean biking - small outrigger pontoons, like you'd find on one side of Hawaiian 'war canoes'. Good luck with all these ideas. - drrota
damned crazy thing I'll follow ! - YaënD
If you weld the hinge a bit higher the wheel will sink a bit more. But I'm not sure if you'll have enough friction to get you move in the river.
