I enjoy my Vespa (GTS250ie) a lot, I use it both for professional transportation, as well as for personal use.
Downtown, traffic is often congested, parking is always expensive or problematic, and the Vespa is a very effective solution to both.
On holiday trips, I started to realize it is actually one of the best vehicles to discover the world :
* riding on a motorcycle (or bike) allows to experience the landscape and scenery in a more intense way (compared to car, bus, train,..)
* it's speed is slow enough to be able to experience everything, yet fast enough to make some progress through the day
* it's not too expensive

The only disadvantage or problem is that you can't really take a lot of luggage with you : there is a small rack at the back, but it only accomodates a small bag. In front of the driver is a hook, which will hold a small rucksack.
I really needed more storage, either for equipment on profesisonal jobs, or for camping gear during the holidays.
After seeing some examples of single-wheel trailers for bikes and scooters, I decided to make a multipurpose-trailer for my Vespa

Given the complexity of this project, and the safety (and road-legal) requirements, this was going to be a project which would take several months. Your needs and capabilities are likely to be different, and so you probably won't be able to build one yourself simply following this instructable. Still I hope that this story may help and inspire you to build one, some day.

Good luck & Hope to meet you on one of my trips one day !

Step 1: Requirements - Parts List - Tools - Costs

  1. Meet legal requirements. They differ from country to country. Google is your friend, as well as the forums of local scooter or motorcycle clubs
  2. Safety : strong construction for worry free rides.
  3. Durable : must withstand Europe's roads and weather conditions.
  4. Payload : >100 liter of volume, and about 40 kg of weight. Legally, the trailer has a maximum weight of 50% of the vehicle towed by (150kg), so that means a total weight of max 75 kg. This led to the option of building it in Aluminum.
  5. Comfortable ride : should not limit maneuverability of the Vespa itself. Ideally it should feel as if there was no trailer being towed/
  6. No permanent modifications made to the scooter. (in case I want to sell it some day.)

Parts list
  1. 12" wheel : I managed to buy one on ebay for 25 euro
  2. Faes Cases Defender Aluminium Case. I used a FA-74 type of 990mm*450mm*380mm (162 liter of volume)
  3. Aluminium tubes : 40mm*20mm*3mm
    1. 2 * 1050 mm
    2. 2 * 400 mm
    3. 2 * 360 mm
    4. 2 * 150 mm
    5. 2 * 380 mm
    6. 1 * 220 mm
    7. 2 * 255 mm
  4. Plywood : 980 mm * 440 mm * 12mm
  5. 2 x 4-function light block (rear light, braking light, turn indicator, license plate light)
  6. 3" caster.
  7. 2nd license plate

I can't be 100% exhaustive on the list of tools, but here are the most important ones
  • Tape-measure, Caliper
  • Steel carpenter's square
  • Disc grinder
  • Drill press
  • AC TIG Welder
Costs : total 500 euro = 650 $
  • Case : 300 euro
  • Aluminium tubes : 70 euro
  • Argon (TIG Welding gas consumed) : 20 euro
  • Plywood : 5 euro
  • Lights : 40 euro
  • Caster : 15 euro
  • Wheel (second hand - ebay) : 25 euro
  • 2nd license plate : 25 euro
loved the way you repurposed the caster for two axis movement, very ingenious!
<p>That's beautiful!</p><p>Looks really professional but simple at the same time. Less is more, as they say. :)</p>
<p>Brilliant! Sketchup model was really helpful in being able to cut the tubing to the correct size, and also as a base to modify the trailer. One question relating to wiring, where did you connect the wiring to on the Vespa (I suspect to keep it simple you may have taken feeds from the existing indicators etc..) </p>
<p>Well done! You've got skills man.</p>
<p>Have you considered making this trailer for order? I would buy one tomorrow if I could!</p>
<p>The simplicity of the design goes well with any scooter or motorcycle. Very cool.</p>
Very good! The caster wheel idea for the coupler is a great idea!
I absolutely love this. I have been wanting to build one for my &quot;Sachs Madass&quot;! I haven't built one because of the expense of the coupling. I love the caster idea and the simple design. Talk about having tail gate party. Great instructible. Thanks for sharing
Very nice execution. I really like the trailer connector. Since the whole thing is longer, do you have any trouble parallel parking, or do you usually just use a normal parking lot space?
Necessity is the mother of invention they say! I think that this will need to be copyrighted as some factory may be interested to build and sell this thing <br>
Very nice pic of the scooter with the brick wall behind. <br>Congratulations
Thanks. The building is the 'museum aan de stroom'. Just google images for MAS to get some more pics.
Have a nice time with it this summer (if weather permits !)
Great work, and the caster wheel idea is pure genius
That is so cool!! I dream of having a vespa. I'll definitely have to build this if I ever get one.
We built a pull-behind our motorcycle trailer based on a Harbor Freight small trailer frame and a SCARGO car topper. We have a large bike--1500 cc--and we don;t even notice her back there. <br> <br>We made the trailer a bit narrower to make it the same width as the bike---something I am VERY happy to see addressed here as I got a fairly BIG argument about it! <br> <br>We are planning on making our own version of a tear drop or other shape soon--the SCARGO is OK but not the most sturdy and things have a bad tendency to SHIFT in there---we made some internal baffles out of ply wood that fit into the &quot;ribs&quot; of the trailer and also put some crates in to seperate things. This also helped us learn how to BALANCE the load for the highway--several re-packs sent us off to a road side Wallyworld for crates and bungies! <br> <br>But for the cost of the trailer frame--something like $200 or less with coupon and sales--and a $10 used SCARGO and a few nuts n bolts; some lights--ditch the Harbor Freight trailer lights as a bad deal and just do yourself a favor and go to PEP Boys or even Walmart and get BOAT TRAILER lights for less than $50---better made; better wiring. much much brighter--you DO want to be SEEN--right?? <br> <br>Harbor Freight has RE-STOCKED their small CARGO TRAILER that is much like the one we built. <br> <br>We did several over nights as &quot;Shake downs&quot; and then trailered across NY State from Eastern border to Buffalo for our sons wedding--then dropped down to West Virginia and Ohio--and we LOVED how we were able to take what we needed and not have to lash things to the luggage rack--already occupied with a trunk bag!--or spend all our evening fumbling around in the saddle bags. <br> <br>Since I am handicapped we were very pleased to be able to haul my &quot;equipment&quot; also. <br> <br>Encourage ANYONE to buy build or borrow one to see what a great thing this is! <br>And consider that a purpose built motorcycle trailer--plain or fancy--STARTS at something like $3000----You can even find plans to make one of the cool fold out CAMPING TRAILERS---Not that hard once you know how! <br> <br>And LOVE the Vespa job!
Does the trailer you built have 1 or two wheels? Does it have a suspension?
You yanks are sooooo great!!! <br> <br>I love how easy you can approach road legal things. I have been in DC, NY, NE, NV, AZ and CA. Wherever I have traveled, I have often seen stuff riding (or driving) down the road that we could only dream of, here! <br> <br>Cheers!
Nice, nice, nice!!!<br> <br> The only things I could think of worrying about are not about your trailer:<br> - that chromed Vespa rack, while it's beautiful, doesn't look up to the job of supporting the hinge of the trailer ... are you sure it will keep up with full load and bumpy roads?<br> - that's a variable speed drive Vespa ... will the belt keep up well with the extra weight?<br> - I see a brake disk there but I guess it's just a spacer for the wheel; how much is the extra weight felt while braking? The distance of the hing from the &quot;middle&quot; axle is not much, and it's very high, so it could possibly even add weight to the front wheel ...<br> <br> Thanks again for the SUPER instructable!<br> Please, drop a note if you pass by Verona or Venice!
Hello 'fmasi', <br>* the rack seems to be OK until now, but you are right, it is something to be monitored. <br>* there is little extra drag, as far as I can feel. I think riding with a passenger is more load to the Vespa than riding with trailer. Of course riding with passenger + trailer is an extra load. <br>* yes, the trailer has no brakes. Legally it only needs brakes if &gt; 500kg. also in braking I don't really notice. Still I have only loaded 30kg until now. Still need to testdrive with 50 kg. <br> <br>When I manage to get Vespa and Trailer on the train to Bolzano, I will make a trip through the Dolomites and visit you :-)
Great! <br> <br>I know very well (very close to be a relative) the vicepresident-secretary of the Vespa Club d'Italia. <br> <br>I am sure that a lot of people would be very happy to have you as a guest in any Vespa event, if and when you plan to pass by while it's happening. <br>Check www.vespaclubditalia.it (Italian only, sorry) for calendars and addresses. Just in case you want to add some random fun to your trip! <br> <br>Cheers.
I have a couple of the original motorcycle trailers called PAV made here in the Czech Republic, so am very familiar with the concept. I was intrigued to see your instructable and all I can say is VERY well done. The use of the caster wheel housing is quite and ingenious to the two axis coupling question. I am sure that you shall keep the bearing in the caster well protected from moisture. I would love to give this a go myself, just for the hell of it but there are funny in this country about putting things on the road that are home made and even a small trailer must have its own documents. Then again on the other hand the police are not exactly rocket scientists. So again very well done.
PRETTY AWESOME . I love the adaptation of the multi axis castor for the trailer attachment .
Mate, my envy is really shooting through the roof ... <br>Because there's no chance they will ever let this marvel be road legal down here in Italy. <br> <br>Thanks for giving shape to dreams.
Fantastic project and you did a real great job on it too. Thanks for posting it.
Did you bush the vertical axis pivot? Seems as though one could incorporate the wheel itself by flattening one section of the circumference and strapping it to the hitching tube.
Could have used a little suspension with a small shock absorber. I've built a small bicycle carrying trailer to tow with my Prius with motorcycle wheels and independent suspension with shock absorbers and it handles like a charm even on Lisbon's &quot;Roman like&quot; stone streets.
Amazing! Looks great!
This is beautiful in every way! You might consider adding a safety strap or cable between the scooter and the trailer. Just in case, since you are asking a lot of the pivot point on that 3&quot; castor.
great instructable; love the coupling
Functional and beautiful, well done. <br> <br>Be careful or you may have to start a garage company building these for all the EU Vespa riders.
Nicely done; I think about doing something like this for my motorcycles and bicycles.
It's unclear where the caster wheel goes.....
The tongue of the trailer gets mounted into where the wheel was. <br> <br>Excellent idea!, Using the swivel castor to gain your dual axis!
See step 4. The caster is there. The wheel gets tossed.
Beautifully done!
Yeah. Ball bearings tend to catch on fire while you're welding them.
Very nice execution, VG instructible. a few things I will change, but I intend to follow your model.
this looks professional bood work!!! if i had a vespa or any other thing i want such a thing, it looks Like a great project,
that is an amazingly simple, yet brilliant idea
Wow!. I think the use of the castor wheel is brilliant!
I agree! The entire project is amazing but I think the castor wheel was the smartest design and construction element. I love when people find new-and-improved uses for common items!
So badass!
This looks great ! I looked at making something similar for my vintage moped, although British law states that a bike under 125cc cannot tow a trailer ...
I believe we have a similar law here in the states. And for anything with a 50CC motor, I would highly recommend AGAINST even trying to construct a trailer for that size engine moped or scooter, as it will burn out the clutch, and over-tax the motor. (this comes from connecting a 2-wheel bicycle &quot;Kiddy&quot; trailer, (which is supposed to be towed behind a pedal bicycle), , and trying to haul some radio equipment for a ham radio field day.) (cost me new piston rings, and BOTH High &amp; Low clutches on a 50cc TOMOS Targa.)
