Towing bicycles

You could probably tow two bikes side-by-side behind your tractor with two sets of fork holders. High CofG, tendency to flop. Not so sure. With the towed bikes attached at their rear racks, the whole system might be very stable. See the aerial sketch below. http://www.johnballcycling.org.uk/photos/towing2b |

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. I'm certainly interested in quick and easy ideas. I'm not really ready for prototypes yet, probably not until well into the New Year. I'm away from 20/12/06 - 7/1/07 anyway, using my mountain bike over the mountains of Hainan.

They could always be lashed further back, I think. It does, however, knock out the use of rear panniers, but frees up front panniers. |

I went for the trailer option: http://homepages.nildram.co.uk/~tali.../biketrail.jpg But there ought to be a way of turning the two bikes into a sort of trailer - I'm thinking along the lines of taking the front wheels out, turning the forks 90 deg and fixing them onto a cross beam on the rack of the towing bike. You'd probably need some sort of tie rod between the seatposts to stop the bikes wandering apart or into each other. |

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 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.

A BikeHod style flexible seatpost hitch might be better than the rack hitch. -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ Error 1109: There is no message for this error |

Silly question, but why are you transporting bikes from school to school? What's the point in training kids without bikes to ride bikes? Surely if mum and dad want their young sprog to ride a bike and be trained by you it's up to them to get a bike to school. Plus if you're providing bikes for training purposes you're liable for any injurys due to faulty mechanics. You're insured for that (sorry, married a US lawyer and now I'm overly informed about liability)? Best of luck with a solution though. Laters, Marcus |

Surely if mum and dad want their young sprog to ride a bike and be trained by you it's up to them to get a bike to school. There are several reasons why school children might want cycle training but not have a bike at school, including: 1. They don't own a bike 2. The bike they have is not suitable 3. They are not yet trained so they are not allowed to ride to school 4. They can't ride a bike The grant I received for pool bikes is to make cycle training socially inclusive. Plus if you're providing bikes for training purposes you're liable for any injurys due to faulty mechanics. You're insured for that (sorry, married a US lawyer and now I'm overly informed about liability)? Insurance is fine. If a child crashes while training - covered If a child borrows a bike and crashes while practising at home due to faulty maintenance - covered If a child borrows a bike and crashes while practising at home due to cyclist error - not covered, not liable Best of luck with a solution though.

I expect a train connected by trail-gators would topple over at red lights. I think I have a simple cheap solution. Wooden boom handle bungeed securely across the rear of the 26" bike's rear rack. Front wheels removed from 24" bikes and forks 'hooked' over the broom handle. 24" bikes bungeed either side of the broom handle at the forks/down tube. 24" bikes bungeed together with a second broom handle at their rear racks, giving a stable trailer. Two 20" bikes, front wheels removed, hooked over the second broom handle and secured in the same way as the two 24" bikes, including at their rear rack by a third broom handle. I'll test it out in the playground at school one day after school next term and take a few shots. |
