a few thoughts about this motorbike-trailer idea......
It is much more stable than it looks . The trick is to make the joint/linkage as high as possible . This way , while cornering , the momentum / centrifugue force tries to hold your bike upright -hence reducing the turning- . If you want to turn , just lean your body a little bit more than expected , but otherwise the result is that *most* people agree is more stable .
I have driven this thing up to a 110 k/h (on tarmac) and up to 80 on a piste. Feels safe , and doesnt make any noise.
Also , I was worried that the trailer ,-not having any suspension - would be destroid / banging /flipping , etc.. but as long as Its got low pressure in the tyres ... it behaves allright . I even drove it in a serious corrugation (Diema Nioro , ) and It hold up really well.
There are -however - a few dangers :
1 in the current configuration , if a car hits the trailer , then the trailers-arm will hit me lethally in the back.
2. If the weight is too far to the rear of the trailer , the arm is triying to lift up the rear of the bike , and that could trigger a nasty hi-side accident . Hoever , if the load is towards the front , It actually holds up the rear wheel with more weight.
3 The f*k%ing ball bearings. These trolleys are intended to carry lots of stuff , but at walking pace , not a 100 ks . so I litterally eat up a set of ballbearings every 1000k. They are dirt cheap and full available (shares the same bearings and shafts from that yamahas 50cc mopeds )
4 You are on a bike , but you are 1 metre wide again . If you forget this , you can kill someone , or destroy a car , or a donkey , or kill yourself . To the point that I was about to put a 1 metre wide stick on my front mud guard to remind me constantly that I was 1.2 metres wide.again
Obviously load Carrying . The trolley is rated up to 200 kilos. Even half of that would make terrible improvements in range / fuel/water , spare parts , etc..
you have the bike "clean" , therefore you can ride someone easily in the back of the bike.
Whenver you arrive at a city , you just simpliy unlock the trailer , park it at an hotel / camping , and then in 1 minute you got your motorbike "street going" ,without boxes , bags , panniers , etc.. . Much more easy than either exploring a city with all the stuff , or taking all the stuff off every day.
Where to get it ?
Well , obviously this can not be driven in Europe ! , but in Bamako , they sell them for about 30000 CFAS (50 EUR) and they will be happy to make all the linkages , attachements for free.
Is it Legal in Africa ?
So far , Bamako is the only place that I had problems . Everything unusual is an invitation for policemen to stop you . I guess any other exotic solution would have been "ilegal" for them . Rest of Africa is ok .. no problems , just smiles , and from time to time , some people which want to get a free ride in the trolley .
Resale Value :
Everywhere , absolutely everywhere , they askme to buy the trolley (they ll think is a exotic European equipment or something ) and offered me up to 200 Euros for it !
How much can you honestly carry on it ?
Deppends on the piste / Track . I put up to 100 kilos and it performed ok.This allows huge increases on range indeed. In critical scenarios Id go confidently for the maximum 200 kilos.
Is the performance of the bike modified ?
Not really . I can honestly not tell from the acceleration/speed if I had the trolley or not.
How well/bad performs in Sand ?
SURPRISINGLY WELL ! . Dunno why , but somehow if helps you to keep your bike straight up. Yep , the trolley wheels "drag" a bit , on the other hand , they pull more weight in your motorbike rear wheel , and so -far I have never got stuck. Maybe other more experienced riders can appreciate some difference , but me -I am absolutely new to bikes , less than 1 month experience before donig this trip!- I can not tell a difference in the handling on sand . If at all , is for the better.
WEll , hope this long boring stuff helps someone to decide for or against pulling a trailer with a bike.
Have a nice day
