No doubt those who wish to compete have been inspired by the remarkable successes of Alan Schmidt.
Danes (and all others) are completely excluded from the only market in the world!
These trikes, trike frame-sets and axle conversion sets will be reserved for serious Danish, handicapped tricycle competitors only. Each trike or conversion set recipient will be carefully vetted for the seriousness of their interest in the sport.
A local bicycle shop can usually remove the wheels and pack a trike properly at a nominal charge. Then hold it until the courier arrives. (usually next day) The cost of packing and freight will be paid for by the buyer. Not the seller.
Sorry, but there is no interest in (two wheel) bikes. Donor racing bikes for turning trike conversion sets into trikes are readily available over here. Nor are "handicap" trikes of interest. These are also readily available in Denmark and completely unsuitable for serious, paracycling competition.
Thanks for your interest and patience,
