Single-Wheel Trailers
Extrawheel
The Extrawheel trailer consists of a stainless steel frame around a single 26''-wheel. The load is held in two nets on either side of the wheel. Thus, it is necessary to distribute the load to at least two pieces of equal weight. The trailer can carry loads of up to 30 kg.
Advantages Extrawheel:
- Extremely well going on difficult terrain and offroads due to the large wheel and the good floor clearance of the load
- Rather light weight (about 5 kg)
- Easy to mount on the towing bike making use of tension forces
- The 26''-wheel can be used as spare parts (rim, tire, spokes) in emergency when traveling in remote areas
Disadvantages Extrawheel:
- It is important to balance the loads, otherwise it won't run smoothly
- Packing the load into the nets is a bit more complicated
- The load is as wide as panniers; this may be unfavorable from an aerodynamic point of view when the trailer is used on a bike without panniers
Summary: The Extrawheel-Trailer is a true expedition trailer! It has its strength really in offroad situations and in difficult terrain. It is not so much the choice for grocery-shopping.
Rather short, but wide load . |
Bike stands when at an angle with the trailer. |
Loads to both side of the wheel need to be balnaced. |
Fork of the trailer is fixed to special rear axis by tension. |
Special rear axis with ball head holds the trailer fork. |
Trailer fork is lower than the panniers. |
Ibex
The IBEX is the suspended version of the classic single-wheel trailer, the YAK from BOB. The trailer is made for a big single piece of load that can easily be accessed from above. It can carry about 30 kg.
Advantages Ibex:
- Big platform for theload, easy to access;, flexible sized loads possible
- Runs very smoothly also at high speeds
- Narrow size, but longer; this is favorable if used with a towing bike without panniers
- Suspension helps to avoid big impacts on the load even on rough terrain
Disadvantages Ibex:
- Rather heavy (about 7.5 kg)
- Small 16''-wheel is disadvantageous in true offroad conditions
- When used on a bike together with panniers, the fork of the trailer may conflict with the rear rack or the panniers
Summary: The Ibex-trailer ist a robuster allround-trailer, which can be used on rough expeditions as well as for every-day purposes.
Great flexibility in size of loads, here with solar panel. |
Ideal for long and bulky items, such as ice axes. |
Suspension prevents damage of the load on rough roads. |
Attachment of the fork on the special rear axis. |
Easy fixation of trailer fork at the axis with a pivot system. |
Panniers and trailer sometimes can cause interference. |
