Here is how I build a simple rowing bicycle with a child’s bicycle and a folding bike.

Several rowing bicycles are available aiming to improve upper body training. However, they are expensive, it is difficult to find local distributors and most of them are not really suitable for everyday use. This one is cheap, easy to drive and fulfils all traffic regulations that I’m aware of.

I open a blog for Spanish and other languages speakers: http://lamarianette.blogspot.com/

Step 1:

Find suitable bikes, in my case a folding bike and a child's bike:
<p>Very nice. Inspiring! Very inventive.</p>
That looks nice! Do you have a video of it?
Thanks, I added the video.
It might be more convenient if you uploaded the video to youtube and then embedded the video into the page. I'm interested, and I can't quite play the video for some reason...
The video is now in you tube: <br> <br>http://www.youtube.com/watch?NR=1&amp;feature=endscreen&amp;v=CJW3lzlbLcU <br>
Wow! This totally brings back childhood memories...at 6 my first bike was a four wheel &quot;Zoom Zoom&quot; push and pull bike with the stationary foot rest incorporated in the front wheel system. It ws simple and had a nice seat. All metal if my memory is acurate. Well done, now I'm going to see if I can recreate my fav childhood mode of transportation...Awesome!
Thanks, I wish you success with your project.
Have you thought, this is a gift from Heaven, for Africa's Amputee Children?
Could be, it is harder to move only with the arms though. The child will be tired soon. On the other hand it is easy to build. <br>For handicap tricycles are available http://bike-on.com/ using rotation movement. With a push-pull movement it is easier to keep equilibrium and driving a real bicycle would be possible. <br>
Yes, those guys are great, you too, some people do make a mark on this world...<br>But those models, I don't see some Blacksmith on Africa making such complex devices, very worthwhile that they are.<br><br>A Tricycle, on the other hand, is a more realistic transport solution, but for kids to feel like kids, again, even for a short while, the bicycle is irreplaceable.
It's really neat! You could even have independently moving handlebars for each hand and turn it into one of those cross trainer things! Might make steering a little hard though...
Thanks, see this one here: <br> <br>http://www.myspace.com/robbobike
Lo del el&aacute;stico, te dura desde los 3 a&ntilde;os: es momento de superar esa etapa y pasar definitivamente a los muelles (mejorando lo presente,ojo), que ya tienes una edad. IMPRESIONANTE la bici, aunque el nombre escogido s&iacute; es manifiestamente mejorable, suena hororoso le&iacute;do...
That's awesome! but do you still have full control of it?
I&rsquo;m also surprised, but it&rsquo;s very easy to drive, also turning while rowing (see movie). You don&rsquo;t have to row all the time (for instance in dangerous traffic), it also works only with pedals, like in any bike. I&rsquo;m commuting every day with it now. I have a back pedal brake, which helps braking while firmly holding the handlebar.
Looks complicated at first, but when one reads the steps, it turns out to be very cleverly and simply done, and well explained. Nice work!
