    I have a KTM e-bike that weighs 22kg and a 2 bike Thule rack on the van that takes a total load of 50kg (but the specs say 19 kg per bike). I would only ever carry one bike. Is it dangerous to use it? With apologies for a stupid question from a 'wet behind the ears' motorhomer!

    Should be fine, I would make sure that bike is placed centrally on rack to spread the weight

    As said.. no problem..

    Put the bike on the rail closest to the van wall.. that minimises the cantilever force.

    be careful going over speed bumps .. take them nice and slow ..

    We have 2 e-bikes on our rear bike rack, together, with fabric panniers, but without the batteries, weigh about 50kg. Our bike rack is rated at 60kg.
    At the end of our last 3 month trip away I found that there was some crazing on the gel coating on the roof in line with the bike rack fittings.
    I took it to a local Rapido repair place and have been assured that it is nothing to do with the weight of the bikes.
    But what I have discovered on reading the leaflet that came with the bike rack is that when loaded the manufactures recommend that you shouldn't drive over 90kph and to reduce speed when it is windy.

    so what was the explanation ?

    speed won't do any damage but dynamic loads can.. however..
    there was a long thread about this and when I suggested that dynamic loads can cause damage I was told I was talking rubbish..that if the maker says it's ok to .. no worries..

    What? The explanation to the crazing?
    I have explained in another thread.
    But apparently it is due to the fact that the Rapido roof, and I assume many other makes are the same, have a floating roof i.e. Not attatched to the solid wood structure beneath. So, under certain conditions things like solar panels, which are stuck to the roof, can bounce/ vibrate causing the gel coat to crack.
    I have to say that I took a little convincing, but the guy that runs the repair shop is an ex employee of Rapido. He assured me that the load on the bike rack was not the cause.

    Yes it's not the cause because the roof skin isn't fastened to the back wall it just hangs over it

    Hi Techno,
    After a lot of soul searching and research we've finally gone out this afternoon and bought ourselves 2 KTM e-bikes (Macina Sport 10 CX5). (stated as 21.7Kg each inc batteries). They'll be on the back of our 'van carried on a Thule 'Sport G2' carrier, with a 50Kg max overall load but 19Kg max per bike load (not sure I understand that unless the max load also includes the weight of the rack 7.9Kg?). I'll be checking on how the rack is actually attached to the back of the Motorhome - just for reassurance.
    I'm interested in the photo you've posted showing the bike cover - it looks a lot more substantial than our previous Fiamma cover which has now torn. What make is it please and can you recommend it?
    Also, as one with limited/no experience of carrying heavier bikes (e-bikes), I'd be interested in any comments you have re our bikes/load situation please.

    Thanks
    John

    OK, thanks for the quick reply Andy, much appreciated.
    Looking at earlier photos of the 'van (Hymer B654) - before the rack was fitted, there were pre-installed fixing points that have been utilised when fittimg the rack. Therefore I'm thinking it's probably ok but will check bolts for tightness,

    Thanks
    John
