Towing bicycles
The problem of transporting children's bicycles from one school to
another is one which had vexed me for some time. I have in the past bungeed bikes to my rear rack, but this has been unstable and not really satisfactory. A trailer would be a solution: http://tinyurl.com/u3l2x from http://www.islabikes.co.uk/images/ga...railer_480.jpg But that has a total of eight wheels, four of which are redundant. What about a solution which utilises at least some of the towed bike's wheels? How viable would this low cost solution be? http://www.johnballcycling.org.uk/photos/towing (Appologies for the poor quality of my sketch - especially the shocking positioning of the bottom bracket of the adult bike.) Would it be possible to tow two bikes side by side in this manner? What about a train, with two bikes being towed in series? Or a combination - four bikes being towed in a 2 x 2 array? Side by side seems the most viable option as the two bikes could be secured together by the rear rack, providing a stable upright position. The diagram is meant to illustrate a 26" bike towing a 20" bike (yes, I know the wheel proportions are wrong). What about other sizes. A 26" bike towing two 24" bikes, or even better, a 26" bike towing two 24" bikes, towing two 20" bikes? The rack extension: Will this be secure enough? Would a couple of broomstick handles secured either side of the crossbar of the lead bike be better? Before I go into prototype mode, almost certainly not until well into the New Year, it would be useful to hear any views or suggestions. |

Before I go into prototype mode, almost certainly not until well into the New Year, it would be useful to hear any views or suggestions. I have a trailer which is redundant and fitted for cycle carriage. If you can pick it up from Derbyshire it could be free to a good home.My wife would be delighted. We have no tow bars. That would be an easier solution. What I did for tjhis problem was buy a cheap folder from Loot .In fact there are some very cheap new folders around for cycle training or short distance use.Then there is no worry about how well they have been mounted on the car.

To reduce the redundancy as long as two bikes have the same size of wheel you could use their front wheels for the trailer. Actually with a little ingenuity you could use different sized wheels either side. How viable would this low cost solution be? http://www.johnballcycling.org.uk/photos/towing How about fixing a set of QR fork holders for a car roof-rack at the rear of the towing carrier. Take out the front wheel of the towed bike and fasten bungee that to the carrier. You could probably tow two bikes side-by-side behind your tractor with two sets of fork holders. -- Phil Cook looking north over the park to the "Westminster Gasworks" |

How viable would this low cost solution be? http://www.johnballcycling.org.uk/photos/towing I just had an idea, lashed a couple of bikes together and rode them up and down the road - it seemed to work quite well, so email[1] me if you want me to make some sketches and discuss further development. I have a vague idea how it could be better implemented in a cheap easy-fit sort of way, but can't concentrate on that right now. [1] address is valid |

A neat practical idea, Phil. http://www.johnballcycling.org.uk/photos/towing2 See amended diagram above: two side by side 24" bikes (shown as one bike), towed by a 26" bike, and towing two side by side 20" bikes (shown as one bike). Front wheels to be attached to front pannier racks (not shown), leaving rear panniers free for hi-vis tabards, tools and [spit] helmets. Attaching a QR fork holder to the rear racks of the 24" bikes is excellent. It will give the whole 'trailer' rigidity to stand on it's own four wheels so the whole thing won't collapse at traffic lights. My main concern is that the centre of gravity is so much higher, especially on the 24" bikes. Any thoughts, anyone? |

Take a piece of 1x-.5 in box section. drop this down behind the back wheel then place a q/r through it at the right height (could do two, one for 20" and one for 24".) That gets the cog down sufficiently. Ascii art follows(need a fixed width font.) showing a rear rack with a towbar attatched. * marks the q/r. Find a friendly metalworker, then bolt the tow bar under your rack. ------- === \ | / \ |/ ) * ...d |
