Small motorbike onboard?

I want to put a motorbike on my boat.

Notwithstanding that one of the reasons why I bought my boat was that their was plenty of deck space (relatively) behind the aft cabin which makes moving around the deck when line handling easier it is also just enough room to put a small motorbike / moped.

My thinking is that it would be something which would be road legal (including in the UK) and would not live permanently aboard, just when I was going foreign. I used to have access to a car in France which I always found useful – even for just “popping” up to the shops or to the hypermarket instead of the local shop, where “only! a couple of km’s on foot becomes a long way back with the shopping bags! – also having a bit of transport does I find increase my exploring range a great deal. I know I could use pushbikes, but I am not really one for them.

Anyway, the “problems” I have is finding a motorbike small enough for TWO people (although both slim!), that will be road legal (at least for one person – I am quite happy to modify something to add a pillion – I know it shouldn’t be done, but………) and then to have a method of getting it on and off the boat.

The Motorbikes I have “found” on the net are these:-


Monkey Bike

Sachs Madass - VERY cool as well!!!

Diblasi - folding motorbike - might need 2 of these!

But today I saw another model which MAY be suitable, given a tape measure – but unfortunately I haven’t got a camera phone and it wasn’t the usual Jap brand name – so I have forgotten it!

What I am thinking is something that would be worth the effort of getting off the boat for only a weekend – not necessarily bringing it aboard each night – although for obvious security reasons this would be nice.

Obviously weight is an issue as well, particularly when it comes to manhandling it in a restricted area (I am NOT a bodybuilder!), but I figure whatever I get I will need some mechanical assistance, so as long the motorbike is small the weight should be ok. Whilst a purpose built derrick / crane would be ideal it is not something that is in the budget or that I would want on the aft deck 24/7 anyway.

However, fortunately I have a mizzen mast and (fortunately??) it will need re-rigging anyway. The shrouds would just about let the boom extend over the side of the boat right at the aft ¼, but the motorbike would need to held right at the end of the boom for it to have any chance of reaching a pontoon – however as the stern does have a slight overhang at the top so the boat could be brought close into the pontoon stern facing with motorbike dropped off that way. Either way I am figuring on it probably being a two handed job and a block and tackle arrangement, with or without the use of any winches so as to “pull” the motorbike away from the vessel for clearance from the hull – especially as the mizzen boom would have to raised somewhat so the motorbike could clear the pushpit. As the boat takes the ground could even just be dropped on the beach I guess.

I know I am stretching here, but anyone done anything similar! It might not be for a motorbike, but say, beefing up the boom fittings etc to turn a mast / mizzen mast into a crane / derrick so that it could be used to lift heavy weights (MOB?) or barrels of beer?! I am guessing that the mast fittings will need beefing up as well as being made so that the boom has greater sideways and up and down movement than is normal and maybe also the shrouds will need to be beefed up?? Anyone got any thoughts? Or suggestions?

Also anyone found any other small makes of motorbike?
 
It seems an enormous amount of faffing and effort for little benefit. If the weather pipes up do you really want all that gear on your stern?

Unless you are too posh to peddle get a push bike! Otherwise hire something when you get there.
 
It probably sounds a bit more gear than it will be.........it will be a seaworthy enough arrangement.......but, yes, it is plenty of faffing around!

Not too posh to peddle, too lazy /forums/images/graemlins/laugh.gif. Hire a car? That would only work if I was going to use it everyday or I would have to plan ahead - with a Motorbike it would be a case of could be used and is just there when needed. Also would be useful when not in a Marina / near an Avis depot.

Agree it will often only be a slight benefit (but very occassionally very useful for me), certaintly compared to the effort involved - but I also like being self sufficient to a degree.......hence me asking for help / views here!
 
As you are determined to try it I'll answer as best I can then!

Unless your mizzen mast and boom are very light weight I would expect them to be able to used a derrick without much modification. You may, however want to strengthen the topping lift which would take most of the load, or you could use the halliard and fix it to the end of the boom. In any event you will probably want to be able to raise and lower the boom and you need to be sure that you can get the lines to a decent winch.....it will be a lot harder work than raising a small sail.
Without knowing the configuration at the head of the mast I can't comment other than to say that most of the strain will be taken there.

I've used a boom like this to lift engines into place and it's perfectly workable......though I wouldn't want to do it routinely.

The other thing to remember is that these bikes won't like salt water and will really need some kind of protection from the elements otherwise they will suffer quite rapidly.

I can understand the appeal of a motorbike, but on a boat? I still think it's daft! Why not go the whole way and install a heli-pad? /forums/images/graemlins/laugh.gif
 
we have had \ de blasi for a number of years , a great piece of kit

particularly useful in this new age of no local shops.
 
Get a Moto x mag as there are loads of 50-120cc bikes out there small light and neat and can be upgraded easily for more power.

Try ThumpStar too.
 
Your mizzen should be fine, I use mine to lift on and off a 125 yamaha trailway, which is pretty heavy, I use a block and tackle from boom end to bike and the topping lift is adequate to do the job of raising the boom, just haul up on boom, make fast and then lift bike with block and tackle to clear handrails, then lower boom until it is over the side, lower the block and tackle, bingo, if you need to pull it to the pontoon, a simple line will do that. Easy peasy, I do mine on my own! As has been said, loads of bikes available, look at some of the 50cc scooters as well, some are stripped down, so lighter. Remeber to make sure you get insurance to cover you wherever you are going to be.

Cheers for the advice - the head of teh mast taking most of the strain makes sense - I will try and factor this in.

This is one of the things that put's me off anything not japanese, particulerly something with even a hint of Italian /forums/images/graemlins/laugh.gif - I've got a commuter Scooter (Aprillia) which has a "retro" styling with plastic chrome which they reproduced 100% faithfully - it started bubbling within a month /forums/images/graemlins/mad.gif

Don't get me started with ideas! /forums/images/graemlins/smile.gif I am sure their is also a joke in here about having a large chopper /forums/images/graemlins/grin.gif

Cheers

Size wise this would be ideal - but it appears to have some italian in it - how is it holidng up? Do you keep it bagged up down below or on deck? and is it the standard or stainless version?

Also is it definately only a 1 person bike? Be a bit pricey for 2 of them..........maybe a sidecar? (joke!)
 
Your description of what I will be trying to do was so much more concise!

That would be nice - whether I achieve that is another matter!

As I said, I will be getting the mast down anyway so their is a degree of sense in beefing things up and making it capable of being a crane - even if the arrangement is "only" ever used as comfort for a MOB - quite high freeboard - the missus is quite small so would have no chance of lifting me aboard, even though their is not a lot of me! (the present MOB contingency is into the Avon, then aboard - but always good to have options).

Thanks guys for the advice and the fact that something similar has been done - obvioulsy will having a chat to the boatyard / other folk who can see the boat and mast - but it is always helpful to have a broad idea of where I am going. Time frame will be spring / summer 2006 at the earliest - will post some photos up IF it works!...........just to show off!

PS the SEGWAY looks interesting, but..........

Japanese will not be proof against salt. Jap bikes dissolve if used on british roads in winter without absurd levels of care (wash off thoroughly each time you use). Now my wife's Ural 650 (probably too heavy for you at 220kg ;-)) that likes it...
 
Why stop at a Bike?

Why indeed! Saw an American MoBo of about 45 foot in Marina Hemingway with a VW Golf on the aft deck. A pair of ramps handled the unloading.
 
Tee hee, love it!!! /forums/images/graemlins/smile.gif /forums/images/graemlins/smile.gif You this a lot on the French canals. When we came up from the Med. a few years ago, the SWMBO (penichette?!!) from the peniche we were in the lock with, took SWMBO shopping in the off loaded car with her.

About 4 or 5 locks further on, they were back, the car was re-embarked as was the shopping, and off we went!! /forums/images/graemlins/cool.gif Fabulous! /forums/images/graemlins/smile.gif

I've had a few in my time - maybe we use less salt down her on the roads, but overall lasted well - IMHO you can't make up for a lack of original build quality.

A Ural!! That would be cool - especially with a sidecar!

My thought process did include a trials bike - just remove the pushpit and "Hop" on up.........but I ain't that good /forums/images/graemlins/smile.gif /forums/images/graemlins/smile.gif
 
I had a Changjiang 750 (Chinese clone of Ural) in Beijing. OK with salt but disastrous with damp (Beijing is semi-desert). Worst electrics of any bike I've known!
