I posted about this trailer under the heading "Budget baggage" on 29th June last year. It was on ebay at £49.99. Recently I discovered the identical trailer from French trailer maker Erde. Possibly a bit of Taiwanese engineering with badges added in France. Not uncommon in the cycling world.
Wheels are 20" steel QR and the out-rigger bars are also quick release to allow easy wheel changing.
The top cover is included in the price and the trailer is fitted with reflectors. It folds flat for storage with the tow-arm underneath.Wilstow claim that this is the only bike trailer to have the German TUV quality cerificate.
This seems to be a good trailer for the money.
If you have one let me know how you get on with it.
