Manky Monkey Motors

A while back I abandoned the idea of building a small camping trailer to pull behind the trike because I thought it would be too much for the drive train to pull. What does the Monkey panel think? ;D

Will depend on the size of trike. I have seen a few trikes towing small trailers through to tear drop trailer caravans.

I've had standard Reliant cars pass me on the motorway with 4 full grown blokes in them. Wouldn't have thought it'd be a problem to tow a small trailer behind a trike.

I have a mate with a 1300 VW with steel body on it that tows a Dandy trailer tent. Think the 1300 may be slightly less or about the same power as Reliant 850 and Reliant will be a fair bit lighter so I would think you will be fine

My GT550 has no trouble towing a standard Erde 102 trailer.  There are rules about sizes and I think mine is marginally too wide - or long, or something, but only just and not really likely to be stopped.

pull a small camping trailer behind the virago with no problems

ok thanks for the assurance! Thinking about it... the standard Reliant would probably be generally heavier overall,and thats without its potential passengers and/or cargo carrying capacity,plus the trailer is only for occasional use.Just me doing the 'belt and braces' thing as usual ::) Gotta go and 'weigh up'  :P the pro's and con's of a trailer for France.

Looking forward Rod it may be worth you making a teardrop. I know you said your Mrs didn't camp but would she with a teardrop? If paying for a trailer you may as well get moneys worth :)

You've got me wondering now. I'm planning on building a single bike trailer to pull wotsit behind my guzzi trike.I think it would be a sight at shows

Nabs....I built a teardrop years ago to pull behind my lead sled.Surprisingly heavy TBH,unless its made of f/glass!

HI Rod im building a teardrop to pull behind my trike you can get the weight down by thickness of woods  base, side, roof, and dimensions or look at THE PICO-LIGHT Teardrop at only 280lbs unladen mine on hold till weather warms a little as at this temp the bonding glue will not cure and your strength is in the van build

Just looked at that. What are you using for the chassis rails? Summat like 1 1/2" box or channel? Im not a fan of plywood out in the weather even if its treated.

One of the UK Ural sites make a teardrop, can't think which one but don't think it's F2 anyway I think theirs is well under 200kilos. May be worth a look

Just looked at them. Easy to make ,but getting the f/glass flat and nicely finished is beyond me!I found a source for some f/g faced ply,but its 9mm thick,therefore a bit heavy.Ive also got some f/glass sheet about 1mm or maybe less thick,very flexible.One side is smooth .Could be rivetted or stuck to a timber or aly frame . I reckon the inside would have to be carpeted with very thin carpet all over,to prevent condensation.
  Hmmmm................. shouldnt have started this thread,its got me thinking! ::)

Bare plywood, Fibreglass tape over the edges (this will strengthen and waterproof), sand smoothish and finish the whole lot with a couple of coats of latex paint.

Done similar to that in the past on stuff. Its deffo an answer to the problem,but looks a bit naff!

Welcome to my world  ;D

you can use 1/4 ply for sides roof and cover with 1mm alloy or the one side plastic coated alloy sheets floor 18mm for rigid strength and chassis is very minimal as strength in wood cube screws and bonding agent

See Rod, you l know it makes sense :)

Ive already formulated the plan and built it in my head mate! Broached the subject of camping in France with swmbo ,the look I got said it all!.........................................................so I wont be building one afterall!! ;D

How about the stuff I have used on the dash of my kit car, Alupanel, two sheets of 0.30mm ally sheet sandwiching a polythene core, very light and a brushed aluminum non scratch surface. Comes in 8 x 4 sheets. May be too flexible for the floor, but ideal for sides. By MultipanelUK ... http://www.multipaneluk.co.uk/products/sign-materials/alupanel/

Mendalot,How thick is this stuff.

Worth considering , I like the idea it comes in different colours.Sounds pricey?

Its 3.5mm and fairly rigid in short bits, the bit for the centre consol in the picture below took a fair bit of force to bend to the shape required. I can send you a sample if required as I have some left over. I get it from a local bloke who makes shop signs and facias, I seem to remember its about £85.00 for a full a sheet.

Nice dash!

8 X 4 sheets? Looks good stuff but could work out expensive . Would need 2 sheets for the sides of a teardrop,plus whatever the roof is done in.
 Whether it be aly or ply,it would still condensate inside,meaning covering with thin carpet.
 A main concern I've always found is the hinge mechanism and the way the door/flap seals. I tried various ideas,but none stopped the rain coming in ,especially as youre travelling when the rain is 'driving' into the gap.I would open the lid to find a line of water across the floor under the hinge area. I ended up having to gaffer tape the join when travelling.When the lid is raised in use,what stops the rain getting in the opened gap at the hinge? There are supposed to be 'piano' type hinges which by design are self sealing,I think theyre made of plastic or nylon type stuff, but Im not so sure even they would work efficiently.

I have two sheets of this stuff, A mate of mine works for a well known House building company,
And brought them home for me,I also have two new sheets of ally about 2mm thick.


  Nice dash.

That'sprobably why the Glassfibre ones don't have a hinged section!

This site might help free plans for a tear drop      http://www.mikenchell.com/images/GenericBenroyPlans.pdf

Thanks for the link, found it really interesting. Got a contact with a CNC router, going to pass it on to him and see if we can knock one up.

I think what we've all forgotten is that there are restrictions of length/width on what can be towed behind a trike!

What sizes are they then Rod

Cant remember! There was a thread/discussion on it a while back. Something like 2.5 metres from centre of trike rear axle to furthest point on the trailer. No more than 1 metre wide.The length should be ok for a Tear  drop,but if 1m width is correct,thats too narrow I reckon.

Going on those mesuerments you would have an internal size of approx 1.5mtrx1/2mtr.

Thats for a solo motorbike. motorbike and sidecar.

AS ABOVE THIS IS FOR A SOLO CYCLE a teardrop comes under a different categorize in size and weight if you look under THE PICO-LIGHT IN YOUR SEARCH ENGINE YOU WILL FIND DIFFERENT SHAPES OF TEARDROPS IF YOU CLICK ON Plans and illustrations in PDF file THY WILL OPEN UP AND GIVE YOU ALL DETAILS TO EACH TEARDROP JUST CLICK ON PIC OF TEARDROP YOU WANT AND THAT WILL OPEN ALL PLANS SIZES WEIGHT ETC

Hmmm....I stand to be corrected,I hope Im wrong TBH,but didnt we have this discussion when BikerGran bought a trailer to tow behind her trike? I was sort of quoting from memory on what was said back then.

So ..continuing on with trailers behind trikes.......Sorry,cant do links,so unable to illustrate my thoughts......Ive seen quite a few pics of trikes towing trailers,some with smaller diameter wheels(eg about 10" trailer rims)or car sized (13"?) look better. Ive got a pair of rims (15") that are the same as the ones on my trike and Im wondering whether they may be over size,so cant decide. I personally think that trike trailers with the smaller diam (usually white painted)wheels look like they have been just hooked onto the back of the trike,while trailers with nicer looking wheels make the trailer look part of the complete unit. A lot of the American trike trailers have larger diam wheels,but English ones tend to have just a pair of white basic trailer type wheels.Whats your thoughts?

When I get around to modifying my lightweight trailer I intend to fit with matching 15" wheels that are on trike. Like you say std 10" wheels look silly :)

Looking on the practical side ,there are pros and cons using wheels that are same as the trike rears. Pros being you will probably have a spare for the trailer,therefore its a spare for the Trike.And as mentioned ,the whole rig will look more of a unit. That spare for the trailer is gonna take up a fair bit more space than a smaller wheel!

There's also the question about the center of gravity being lower with small wheels less pron to turn over

Think you can drop the chassis below te wheel centre as they are usually stub axle or indispension type units. Would give you bibber wheel arches though

Yes you could mount the units inside the trailer body,ie above floor level.I dont think it would greatly affect the load space,or stability. A while back I mounted the units like this when I built a flat bed trailer that needed to be as low as poss for loading stuff from a drop down rear ramp.

There is also the weight difference,
The fifteens will probably be three or four times heavier.

As someone who tows a trailer, here's my five pennorth.

The trailer with small wheels looks fine behind the trike (if I can find a pic I'll post one)
I don't carry a spare, this was a conscious decision because of the weight, as my trike isn't very heavy and the law says that the maximum weight of unbraked trailer and load should not be more than half the weight of the towing vehicle.
My trailer is technically slightly oversize for the regs, so little in it that I don't worry about it, but I wouldn't want wheel arches taking up any of the space - also it would be less stable with the wheels inside.

Pic below is the trailer not actually hitched to the trike but gives the general idea.  It's an Erde 102
External Dimensions
Overall Length    1.74m    5’8”
Overall Width    1.25m    4’1”
Overall Height    0.82m    2’7″
Internal Dimensions
Length    1.06m    3’5”
Width    0.85m    2’9”
Depth    0.32m    1’2”

Good info there BG,thanks.

What's it like to tow a trailer with a trike Bobbi? Does it restrict your riding in any way? I've ridden plenty of trikes, but never towed anything.

Most of the time I forget it's there, in fact I have to remind myself to stay within the towing speeed limits.  I't a bit disconcerting if I leave something rattling around inside the trailer cos I wonder if it's coming unhitched!

The only real difference I notice is going up a long hill, I might have to change down a little earlier.  And this is with just a 550cc engine, and a fully loaded trailer.  Which is why I have neither a spare wheel nor a jockey wheel - all extra weight!

But it really is good when I pack up the camping gear at the end of the weekend, just to dump it in the trailer instead of having to pack it carefully on the rack and cover it with a tarp and remember which bungee goes where.....  Makes it a lot easier.

If I ride to Basingstoke I'll bring the trailer, but unless it's a really sunny day (haha) I'm more likely to use the car with the trike on the towing dolly, I think that would be of interest to lots of folks.

I have built a few trailers of various types over the years, but a type that I haven't built uses a single, oil vane, damped wheel, and the only example I have seen in use, albeit many years ago, seemed very effective, and as you don't use an articulated hitch, but rather fixed arms, might suit a trike rather well I feel,worth checking out anyway Rod, ciao, Morrag

If they're fixed arms, would it still count as a trailer? Or merely an extension of the vehicle?

Well, I would not be sure, but back in the day, it was described as a trailer, and is of course demountable, so not a fixed extension of the towing vehicle, which in the original case was a car, Morrag

So what's an "oil vane, damped wheel"?
Sorry, just curious as to how it pivots. I've seen small single wheeled trailers being towed by scooters & microcars, but think they were on fixed axles.

Someone was producing (or trying to) a one wheel trailer a year or two back Morrag. Can remember seeing it linked from some bike and trike related sites but can't think who it was or what they called it. Can't remember if it went into full production or not either

The trailer I saw was over 40 years ago, and manufactured quite successfully in the UK. The 'vane' damper was effectively the vertical shaft of the suspension unit running in a cylindrical oil-bath, with a vane welded to the shaft, it damped the oscillations inherently created by the road surface, thus keeping the plot running in the line of the towing vehicle. The guy who had this trailer swore by its efficiency, so.......

There are one-wheel trailers available designed specifically for towing from a motorcycle.

Yeah, BG, but those use conventional style articulated hitches to allow for the "banking" action of a solo when cornering, this type of trailer is designed to stay upright,as per conventional 3 or 4 wheeled vehicle towing, Morrag

Sorry to drag this up again......... ::)...having done more research on trikes towing trailers,I think I am right in saying that the sizes I quoted before are correct ,ie 2.5 M max from centre of trike axle to rear of trailer,and 1M max width. Someone has quoted chapter and verse on it from D of T regs. Im going to confirm it by phoning the DOT on Monday. So surely this would mean a teardrop is too large to tow dimension wise,let alone all the weight/braked/unbraked regs.

Probably is, and I wouldn't even try with my little trike - but have you ever heard of a triker being stopped for towing an oversized teardrop?  I haven't!

I believe those figures are for solo motorcycles and motorcycle/sidecar outfits.
The only limit I can find is a 254kg gross weight of trailer and load instead of the 150kg limit for bikes and combos.
Don't think legislation has yet caught up with trikes but I could well be wrong. A call to VOSA might be a good idea.

No one seems to mention size,They all talk about weight,
Bit of a discussion going on here.
http://www.ukcampsite.co.uk/chatter/display_topic_threads.asp?ForumID=10&TopicID=201306&PagePosition=1

I saw that Hunter,but it was posted in 2009,and I think the rules have changed since then.
 ON ..I think they have lumped the whole lot into one category now.
 BG...youre probably right,but I wouldnt like to be the first person to get a tug. I reckon they will make a huge example of the first one,to make the others think twice about doing it!
  I dont think VOSA deal with this. I'll give their policy dept a ring on Monday as well.
 
 Also the single wheel m/cycle trailers (not the type like Morrag spoke of)(but maybe!) rely on a connection to the bike/car that isnt a 'towball and socket ' type. I think there are also rules (British Standards or summat ::))and specs for the type of hitch allowed as well! I wanted to fit a vertical pin on my trike,and use a large rod end on the trailer,to give a more streamlined look,but I think that is illegal,even though I reckon it would be stronger than the 'pressed tin' tow hitch that is the correct type! I know tractors have the pin and ring system ,but they probably are ok cos its for agricultural use? Can of worms/minefield!! ::)

i think that vosa will tell you to contact D-f-Transport.
the best way is to go to your local police traffic station and talk to them
i done that to find out about my trike tow frame. it was a lot easier than talking to some one on the phone. who might not really know

TBH I havent got any faith in their knowledge so I wouldnt bother with them. I think the only way is to get a copy of the DOT regs and read them!

Some HGV's (if they are still called that) have ring and pin type hitches Rod, it isn't just agricultural. Well it wasn't when I was in the quarry anyway

Well there the ones that will nick you if your braking the law

This is what you will get from the DfT

Thank you for your telephone call to TTS Division about towing trailers.  I attach our information sheet on Requirement for Trailers.

The towing of trailers by motorcycles is covered by the Road Vehicles (Construction and Use) Regulations 1986, Regulation 84.

This states that for motorcycles with an engine capacity exceeding 125 cc:

i)          the trailer has an overall width not exceeding 1 m;

(ii)         the distance between the rear axle of the motor cycle and the rearmost part of the trailer does not exceed 2.5 m;

(iii)        the motor cycle is clearly and indelibly marked in a conspicuous and readily accessible position with its kerbside weight;

(iv)        the trailer is clearly and indelibly marked in a conspicuous and readily accessible position with its unladen weight; and

(v)         the laden weight of the trailer does not exceed 150 kg or two thirds of the kerbside weight of the motor cycle, whichever is the less.

In addition, the unladen weight of the trailer should not exceed 254kg.

The 254 kg unladen limit is applicable to both motorcycles and trikes, whereas the 150 kg laden limit is an additional requirement only applicable to motorcycles.  In practice the laden limit for motorcycles implies that the unladen weight must be less than 150 kg and so, inevitably, the trailer will also comply with the 254kg unladen weight.

There is no need for it to have only one axle although we are not aware of any evidence that single axle trailers have any particular problem with snaking.

Finally we  suggest  you  check with the manufacturer that your  bike has been designed for use while towing a trailer, in particular they may specify a lower laden weight than stated above if the vehicle brakes are not designed to stop a fully laden bike plus a trailer laden to 150kg.


I hope this is helpful.

Yours sincerely

Requirements for Trailers

Statement

Requirements regarding trailers used on the road are given in the Road Vehicles (Construction and Use) Regulations 1986, as amended (C&U) and the Road Vehicles Lighting Regulations 1989, as amended (RVLR).  The following is a summary of the main requirements.

Every effort has been made to ensure that it is factually correct but recipients should check with the producers of this document if they are unsure about the validity of a particular regulation after the date of publication or if they have reason to believe any part is not correct or is now out of date.

1   Weight

In the case of light trailers, that are less than 3500kg in maximum laden weight, there is not any specified relationship in UK law between the weight of the towing vehicle and the weight of the trailer.

For M1 category vehicles (motor vehicles used for the carriage of passengers and comprising not more than eight seats in addition to the driver’s seat) the maximum permissible trailer weight may be quoted by the vehicle manufacturer. Alternatively, the vehicle manufacturer may provide a maximum gross train weight (the laden weight of the trailer plus the laden weight of the towing vehicle). If either of these weights are exceeded it is possible that the Courts or Insurance Companies may take the view that this constitutes a danger.

The maximum laden weight of a trailer which may be towed by an M1 or a light goods vehicle depends on
the stated gross train weight of the towing vehicle (GTW) and/or
the vehicle manufacturer’s recommended maximum permissible trailer weight. 
Neither the maximum permissible trailer weight nor the maximum gross train weight (the laden weight of the trailer plus the laden weight of the towing vehicle) should be exceeded. 

It is possible that the stated gross train weight is less than the sum of the stated maximum permissible laden weight of the towing vehicle and the stated maximum permissible laden trailer weight.  In this case the towing vehicle and the trailer must be loaded such that each does not exceed its individual maximum limit and the sum of both does not exceed the maximum gross train weight.

It is not a requirement to display a notice of the unladen weight of the trailer or the towing vehicle, unless the towing vehicle is either a motor tractor or a locomotive, as defined in the C&U.

2   Dimensions

If the towing vehicle has a permissible gross weight in excess of 3.5 tonnes the maximum width and length of the trailer are 2.55 metres and 12 metres respectively. If however the gross weight of the towing vehicle is 3.5 tonnes or less, then the maximum permissible width and length for a drawbar trailer are 2.55 metres and 7 metres respectively. In both cases, the overall length of the towing vehicle and trailer must not exceed either 18m or 18.75m depending on the type of towing vehicle. If the vehicle combination (not including buses) is of the articulated category the maximum permissible width and length of the semi-trailer are 2.55 metres and 12.2 metres respectively. The overall length of the towing vehicle and trailer must not exceed 15.5m. 

The C&U definition of the overall length of a trailer makes it clear that the coupling device and draw-bar are not included in the length dimension. In the case of a caravan, where a protective box is mounted on to the front (for example to hold gas storage tanks) and is supported on the draw-bar, this box is included in the overall length.

These requirements also apply to visiting vehicles.  Under Regulation 4(4) Item 2 of C&U, we permit a vehicle to be brought into Great Britain by a person resident abroad, provided that the vehicle complies in every respect with the requirements relating to motor vehicles or trailers contained in:

article 21 and paragraph (1) of article 22 of the Convention on Road Traffic concluded at Geneva on September 19, 1949 and Part I,  Part II (so far as it relates to direction indicators and stoplamps) and Part III of Annex 6 to that Convention; or
paragraphs I, III and VIII of article 3 of the International Convention relative to Motor Traffic concluded at Paris on April 24, 1926.

Therefore we provide visiting vehicles an exemption from the construction, equipment and maintenance of vehicle requirements specified in Part II of C&U but not from the requirements for Regulations 7, 8, and 10, which relate to length, width and height respectively.

There is significant harmonisation of regulation within the European Union and freedom of movement across borders. European Council Directive 96/53/EC, Annex I, states the maximum authorised dimensions for certain road vehicles circulating within the Community. However Annex I relates to large passenger carrying vehicles, large goods vehicles and trailers with a weight of over 3500 kg. There are no specific requirements for light vehicles.

Article 3(2) permits Member States to require vehicles, not covered by Annex I, put into circulation in their own territory, to be in conformity with their own national requirements.

The UK is permitted to refuse to admit vehicles into the UK if the dimensions exceed limits fixed by the domestic legislation.

3   Brakes

Braking requirements are prescribed in Regulations 15 and 16 of C&U:
 
A trailer with a maximum design laden weight of more than 750 kg must be braked
An inertia (overrun) type braking system may be used up to a maximum permissible laden weight of 3500kg. 
It is not permitted to use an unbraked trailer, the laden weight of which exceeds 50% of the kerbside weight of the towing vehicle.
The braking system must be fitted with a device to stop the trailer automatically in the event of separation of the main coupling.  This is normally achieved by a breakaway cable attached to the parking brake mechanism which applies the brakes when the trailer becomes detached from the towing vehicle. However, for trailers up to 1500kg laden weight, it is permitted to use a secondary coupling (chain, wire rope, etc) which in the event of separation of the main coupling, will retain the trailer attached to the towing vehicle, prevent the nose of the trailer from touching the ground and provide some residual steering of the trailer.   
An inertia braking system must allow the trailer to be reversed with the towing vehicle without imposing a sustained drag force exceeding 8% of the technically permissible maximum mass of the trailer. Devices used for this purpose must act automatically and disengage automatically when the trailer moves forward.

4   Lights

The requirements for trailer lighting can be found in The Road Vehicles Lighting Regulations 1989 as amended (SI No.1796).  A copy can be obtained from The Stationery Office, or see Section 7 below.

5   Suspension and Wings

Most trailers will need to be equipped with suitable suspension between each wheel and the frame of the vehicle as required by C&U Regulation 22.  They will also require wings or other similar fittings to catch mud, water, etc thrown up by the rotation of its wheels as required by C&U Regulation 63.  .

6   Coupling devices (Towbars)

Any coupling device fitted to a passenger carrying vehicle with up to eight seats plus the driver that:

   a)  has European Whole Vehicle Type Approval (ECWVTA) and
   b)  that the manufacturer has authorised to tow a trailer and
   c)  is first registered on or after 1 August 1998

must be type approved in accordance with EU Directive 94/20/EC.  (Regulation 86B of C&U)

Modification to the coupling in any way, for example, by the addition of other devices that alter the position of the centre of a coupling ball, will render the approval invalid unless the coupling device manufacturer has taken this into account during approval of the device.  You will need to consult the manufacturer for advice.

A vehicle that has ECWVTA will have a Vehicle Identification Number plate (VIN plate) bearing the vehicle manufacturer’s name, chassis number and an approval number including the letter ”e” in a small rectangle.

If the manufacturer has not authorised the towing of a trailer by declaration during the type approval process, it is not permitted to fit a coupling device or tow a trailer.

7    Legislation

The Regulations referred to above may be obtained through The Stationery Office (TSO) under the references, SI 1986 No.1078 for the Road Vehicles (Construction and Use) Regulations and SI 1989 No. 1796 for the Road Vehicles Lighting Regulations.  However, there have been many amendments to these base Regulations and it is important to obtain all of these in order to be aware of the current situation.   

As an alternative, you may find it easier to visit a good, city based, reference library where a publication such as The Encyclopaedia of Road Traffic Law and Practice, published by Sweet and Maxwell, may be available.  This publication tracks the amendments to legislation and presents them in a consolidated and up-dated form.  One of the volumes will contain both the Construction and Use and Lighting Regulations.

Ah! Theyre the people I was going to phone on Monday,didnt think they were open Saturdays.
 Tis true the police are the ones to enforce the law,but what I meant was ,they arent exactly always clued up on each individual scenario. Ive found that they have varying views and ideas on the same subjects when it comes to specific 'odd' things,like trikes and trailers for instance.I'll have aread of the above stuff,thanks Terry.
  Have read the above,but cant see where it mentions Trikes specifically regarding sizes. Are trikes now in the same category as Bikes? It only mentions Trikes when it talks of the weight.

there not  open on Saturdays. ive had this email from them for a while now.
the weight is max unladen for a trike 254kg or 2 thrirds the trike weight. i also take it that its for class 3 trikes
