...Do it yourself

Click the Pictures to visit the relevant sites.

So you've had a good look around all the trailers and you think you could build something to better suit your needs. At the simple end of the scale you could make something like the Traileron (pictured top) which is sadly out of production now since the tragic Hurricanes & flooding in it's home town of New Orleans. It's a bit of PVC pipe drilled through to slide onto your saddle stem and semi drilled to provide a notch for the handle of your golf or shopping cart to sit in. It will even fit a four wheel garden truck if the truck has a ] shaped handle. Both ends have heavy duty rubber bands fitted for security and stiffness.
For a simple cart you could just cut out a piece of marine ply and mail order a parts pack from Bicycle R Evolution in the States. Stub axles and a hitch to fit to the rear axle of your bike are included as are the (rather small and rather plastic) wheels.

In my opinion the best axles for bike-trailers are wheel chair stub axles as these are durable and are designed to be mounted outboard of the vehicles frame for a stable, wide track, (track= measurement between wheels). A variation on this arrangement is used on the Carry Freedom Y frame trailer which uses wheelchair wheels but Carry freedom machine their own axle ends to fit.

Wheelchair wheels have push button centres which release the wheels from the axles to facilitate easy tyre changing or transportation of the trailer in a bag.
Obviously bike or pram wheels can be used. I means that just like your bicycle front wheel it needs supporting from both sides. I have seen scrapped front forks used horizontally for this. Otherwise you need to design your frame something like the camcart chassis. The Camcart frame is all steel and attaches to the bike via a high hitch. The hitch in itself is novel. It's a half size version of the 50mm ball hitch that every caravanner is familiar with. It bolts via two flat plates through the A formed at the top of the saddle stays of your bike. The Burley Flatbed also uses this double tube approach to mounting the wheels and it's Burley's picture which shows the best detail.  Many approaches and materials have been used including steel, aluminium, pvc pipe, wood and bamboo. I'll leave you for now with some pictures and a video to give you some designs to think about and will return with some more sources of plans, parts and "How to" videos in the next blog. Please email or comment if you have any queries, information and or photo's for inclusion in this series.
