Advantages of our construction

· Remarkable stability. A great pile of luggage on the trailer is leaning on curves together with the bike displaying a lightweight performance which is causing general amazement. This is owing to the inconspicuous-looking fastening (fork) which at the same time is unusually rigid. Its arms go right in the middle of the ball-shaped joints and they only transfer longitudinal stress; just like a stick which is hard to break by pressing its ends. That’s why they can be so light and thin. The trailer is also marked by:

·  record-breaking lightweight performance – Extrawheel is the world’s lightest one-wheel bicycle trailer (4.8 kg with a 28-inch average quality wheel);

·  manoeuvrability – retaining the bicycle’s turning radius (the wheel is not placed behind but between the load, and the distance between the trailer’s wheel and the bicycle’s back wheel is smaller than the bicycle’s own wheel space);  

·  little rolling resistance (use of a large wheel);

·  functionality and simple operation – quick attaching and detaching of the fork (fastening); easy fixing of almost any load (self-locking buckle) and releasing it with a single movement of one hand;

·  easy storage – the trailer is not much wider than the wheel itself;

·  reduced risk of injuries (no hard trailer components protruding from the side);

·  wide range of wheels to choose from (large wheel);

·  minimum load on the bicycle’s rear axle (placing the wheel close to the centre of load gravity);

·  simplicity and safety of the fastening – making use of the fork arms’ resilience (specially quenched steel) instead of complicated clasps plus emergency detaching available in case of accident;

·  option of hanging the trailer, for instance over your shoulder (adjustable strap);

·  streamlined beauty – light net tautened by composite poles on the mudguard with ABS Cordura^®

·  price

Apart from the all-use quick release hub lock (available in the package), which is used to replace the bicycle’s rear wheel fastening, and the nuts 3/8'' 26 coils an inch (fitting a great majority of bicycles available on the Polish market), there are also three kinds of nuts (3/8'' 24 coils an inch, M10x1 and 13/32'' 26 coils an inch) available on special request.
