BoB
BOB build single-wheel trailers and strollers that track beautifully behind a bike or run on rough ground. The single wheel follows your line on narrow trails and towpaths where a two-wheel trailer simply won't go.

Is BOB right for you?
Tell us your bike, load and route and we'll help you decide.
BOB | The narrow way to carry your kit
BOB isn't the cargo trailer we'd suggest for everybody. That's exactly what makes it interesting.
Its single-wheel layout keeps the trailer narrow and following behind the bike, which makes much more sense when you're touring, heading onto narrower tracks or carrying kit somewhere a broad two-wheel trailer starts to feel cumbersome.
If you're hauling weekly groceries, we'd probably show you something else. If you're packing the bike and pointing it towards gravel, trails and a few days away, BOB becomes a very different proposition.
- Single-wheel simplicity — narrow and in line with the bike
- Made for travelling — a natural fit for touring and adventure loads
- Specialist rather than universal — excellent when the route matters as much as the cargo

Which BOB bike trailer is right for me?
The current BOB cargo bike trailer range centres on two models: the BOB YAK and BOB IBEX.
Both use BOB's distinctive single-wheel design, which creates a narrow trailer that follows closely behind the bicycle and is particularly well suited to cycle touring, bikepacking and adventure riding.
The BOB YAK uses a rigid chassis and is a strong choice for road touring, cycle paths and general cargo transport.
The BOB IBEX adds adjustable suspension, making it better suited to riders who regularly encounter gravel tracks, trails and rougher terrain.
Both are available in versions for 26-inch and 28–29-inch bicycles.
Hitch-A-Bike supplies BOB bike trailers and compatible accessories in the UK and can help identify the correct trailer and axle connection for your bicycle.

What is the difference between the BOB YAK and BOB IBEX?
The biggest difference between the BOB YAK and BOB IBEX is suspension.
The YAK uses a rigid single-wheel chassis. It is lightweight, simple and particularly well suited to road touring, commuting and journeys where the surfaces are relatively smooth.
The IBEX adds an adjustable suspension system designed to improve control and cargo protection when travelling over rougher surfaces.
Both have a 62 × 40 cm loading area, 16-inch trailer wheel, narrow single-track design and maximum load of 32 kg.
The YAK weighs approximately 6.1 kg, while the suspension-equipped IBEX weighs approximately 7.7 kg.
For primarily road-based touring, YAK provides the simpler solution. For gravel, trails and more adventurous touring, IBEX's suspension can provide a significant advantage.

What are the advantages of a single-wheel BOB bike trailer?
Unlike a conventional two-wheel cargo trailer, a BOB trailer has one wheel positioned directly behind the bicycle.
This gives the trailer a narrow profile that follows the bike's line through corners and narrow spaces.
The design also gives BOB trailers a low centre of gravity, helping create stable handling when the load is correctly packed.
This makes BOB particularly attractive for cycle touring, bikepacking, gravel riding and narrow trails, where the width of a conventional two-wheel trailer can be restrictive.
The trade-off is that a single-wheel trailer becomes part of the bicycle's balancing system, so careful loading and smooth riding technique are important.
For a comparable single-wheel cargo trailer from a different range, Hitch-A-Bike also supplies the Burley Coho XC, designed for gravel, trails and bikepacking.

Is the BOB IBEX suitable for off-road cycling and bikepacking?
Yes. The BOB IBEX is specifically designed for riders who need a single-wheel cargo trailer with suspension.
Its adjustable suspension can be set for loads from approximately 6.8 to 32 kg, helping the trailer respond appropriately to different cargo weights.
Combined with its narrow single-track layout, low centre of gravity and 16-inch wheel, this makes IBEX particularly well suited to gravel roads, forest tracks, bikepacking and adventure touring.
However, riding with a loaded trailer changes the bicycle's handling and braking characteristics. Speed and riding style should always be adapted to the terrain and cargo being carried.

How much weight can a BOB YAK or BOB IBEX carry?
Current BOB YAK and BOB IBEX trailers have a maximum cargo load of 32 kg.
Both provide a loading area approximately 62 cm long × 40 cm wide.
The rigid BOB YAK weighs approximately 6.1 kg, while the suspension-equipped BOB IBEX weighs approximately 7.7 kg.
For the best handling, cargo should be securely packed and positioned so that the trailer remains balanced.
The 32 kg maximum is a limit rather than a recommended everyday load. Bicycle suitability, terrain, braking performance and the rider's ability to control the additional weight should all be considered.

What size bicycle will a BOB YAK or BOB IBEX fit?
Current BOB YAK and BOB IBEX trailers are available in dedicated versions for 26-inch bicycles and 28–29-inch bicycles.
This means it is important to select the correct BOB trailer version for your bike rather than assuming one frame size fits every wheel diameter.
BOB trailers are suitable for several types of bicycle, including city, touring, mountain, sport and tandem bikes, subject to rear axle compatibility.
Wheel size is only one part of compatibility. The bicycle's rear hub width and axle type must also accept the appropriate BOB connection.
Hitch-A-Bike can help UK customers check both wheel size and rear axle compatibility before ordering.

Can I use a BOB trailer with a 29-inch mountain bike?
Yes. Current BOB YAK and BOB IBEX models are available specifically for 28–29-inch bicycles.
This makes BOB an option for modern 29er mountain bikes as well as touring, hybrid and other bicycles using larger wheels.
The correct trailer version must still be combined with a compatible rear axle.
Modern mountain bikes frequently use 12 mm thru-axles rather than traditional quick-release skewers, so an appropriate BOB-compatible thru-axle may be required.
If you're unsure, Hitch-A-Bike can help identify the correct BOB trailer and axle for your 29er.

Does the BOB IBEX have adjustable suspension?
Yes. BOB IBEX features adjustable suspension, which is the principal difference between IBEX and the rigid BOB YAK.
The suspension can be adjusted for cargo loads from approximately 6.8 kg to the trailer's maximum 32 kg load.
Correct adjustment helps the suspension work effectively according to the amount of equipment you're carrying.
This is particularly useful for bikepacking and touring, where your load may vary significantly during a journey as food, water and other supplies are added or used.
If suspension isn't necessary for your riding conditions, the lighter and simpler BOB YAK may be more appropriate.

What is the BOB Bag and how much does it hold?
The BOB Bag is a purpose-designed cargo bag for the BOB YAK and BOB IBEX.
It provides approximately 94 litres of storage capacity, allowing clothing, camping equipment and other touring gear to be packed together rather than individually strapped to the trailer.
The bag is designed to help protect luggage from sun, dust and water and fits within the BOB trailer's cargo area.
For touring and bikepacking, using the dedicated BOB Bag can also make loading and unloading significantly easier because the complete luggage bag can be removed from the trailer at your destination.

Can I use a BOB trailer with an e-bike?
A BOB trailer may be compatible with many e-bikes, but compatibility needs to be checked carefully.
The important factors include the bicycle's wheel size, rear hub width, axle specification and whether a suitable BOB axle or adapter is available.
Modern e-bikes frequently use 12 mm thru-axles, so the standard quick-release connection supplied with some BOB configurations may not be appropriate.
The additional weight of the trailer and cargo will also affect acceleration, braking distance, battery consumption and handling.

Which axle or adapter do I need for a BOB YAK or BOB IBEX?
The correct BOB connection depends on the rear axle fitted to your bicycle.
Current BOB YAK and IBEX trailers include a special quick-release skewer suitable for compatible rear hubs up to approximately 140 mm wide.
BOB also offers alternative connections for other bicycle configurations, including solid-axle adapters and 12 mm thru-axles.
For example, current BOB accessories include M12 × 142 mm thru-axles with different thread pitches, including 1.0 mm and 1.5 mm.
These measurements must match your bicycle exactly. A 12 mm axle of the wrong length or thread pitch is not interchangeable simply because its diameter is the same.
For M10 × 1.0 solid-axle bicycles, Hitch-A-Bike also supplies the specialist Robert Axle Project adapter for BOB Trailer.
If you're unsure which BOB axle you require, provide Hitch-A-Bike with your bike make, model, year and rear axle specification — or clear photographs and the markings on the existing axle.
