BOB Cargo Trailers: Yak vs Ibex for Bikepacking, Camping and Off-Road Adventures

There is a familiar moment at the beginning of almost every bikepacking trip.

The tent is packed. The sleeping bag is compressed. The stove, food, waterproofs, tools and spare layers are lined up on the floor. Then you look at the bicycle and wonder how all of it is meant to fit. 

For riders carrying camping, photography, fishing or touring equipment, a cargo trailer can make adventure cycling considerably more practical. That is where the BOB single-wheel cargo trailer earns its name: BOB stands for Beast of Burden.

Rather than placing all your luggage on the bicycle, a BOB trailer carries the load low behind the rear wheel. Its narrow design follows the line of the tow bike, making it well suited to touring, gravel tracks, forest roads and narrower trails where a wide two-wheel trailer may feel cumbersome.

At Hitch A Bike, we offer two distinctive options: the lighter, unsuspended BOB Yak 26 in Black and the suspended BOB Ibex 28 in Gold.

Both carry the same maximum payload, but they are designed for different bikes, terrain and styles of adventure.

Why use a single-wheel cargo trailer for bikepacking?

Traditional bikepacking luggage is designed around travelling light. That is part of its charm, but it can also become restrictive.

A frame bag may compete with bottle space. A large saddle bag can sway. Fork bags add weight to the steering. Panniers are practical but need a suitable rack and make the bike wider through gates, traffic or narrow tracks.

A BOB trailer places the load in a low cargo bed. Its single wheel tracks behind the bike, while its narrow frame can negotiate routes that would be awkward with a broad utility trailer. Both models use 4130 chromoly steel frames and carry up to 32kg—although that maximum should not become a packing target.

A trailer does not make weight disappear: you still need to accelerate, control and stop it safely. It provides a dedicated platform without attaching every item to the bicycle, which can suit bikes without rack mounts or riders using several compatible bikes.

The single-wheel arrangement also means the trailer follows the tow bike’s path more closely than a wider two-wheel cargo trailer. This can be especially useful on narrow lanes, forest tracks and singletrack, although gates, steps and tight barriers still need to be assessed carefully.

BOB Yak 26: the lighter choice for touring and mixed surfaces

The BOB Yak 26 is the simpler and lighter of the two trailers.

It weighs approximately 6.1kg, has a 32kg load capacity and uses a 16 x 1.75-inch trailer tyre. Its chromoly cargo frame provides a loading area of roughly 64 x 41 x 46cm. The supplied equipment includes the quick-release attachment system, spare attachment pin, spider bungee, safety flag, mudguard and reflectors.

This version is intended for 26-inch bicycles, including many traditional mountain bikes, touring bikes and older expedition builds. The Yak has no suspension, which keeps the design straightforward and reduces its weight by around 1.6kg compared with the Ibex.

It is a strong choice for:

• Road and cycle-path touring

• Canal towpaths and converted railway routes

• Compact forestry roads

• Smoother gravel tracks

• Camping weekends

• Commuting and everyday utility trips

The Yak is not limited to perfect tarmac. Its low cargo position and single-track layout make it capable on mixed terrain. However, because its rear wheel is unsuspended, the rider needs to choose lines carefully on rocky tracks, roots, deep potholes and repeated rough surfaces.

Think of it as a dependable expedition mule rather than a miniature downhill rig.

Its relative simplicity will appeal to riders who favour equipment with fewer moving parts. When the planned journey is mainly on quiet roads, compact gravel and moderate trails, the Yak offers the essential BOB advantages without the additional weight of a suspension system.

BOB Ibex 28: suspension for rougher adventures

The BOB Ibex 28 is for riders who expect the surface to become considerably more interesting.

It has the same 4130 chromoly frame material and 32kg maximum load, but adds a fully adjustable suspension system with approximately three inches of travel. Its wider 16 x 2.125-inch trailer tyre and suspension help the wheel follow uneven ground and reduce impacts transmitted through the trailer and cargo.

The Ibex weighs approximately 7.7kg. This version is intended for 28-inch, 29er and 700c bicycles, making it especially relevant to modern mountain bikes, gravel bikes, touring bikes and compatible e-bikes.

It suits:

• Rough gravel roads

• Forestry and estate tracks

• Mountain-bike touring

• Rocky or rutted bridleways

• Remote camping trips

• Riders carrying camera or technical equipment

Suspension does not turn every path into a trailer route, but it gives the Ibex a clear advantage on washboard gravel, roots, stones and repeated uneven sections.

The suspension should be adjusted for the actual load. Pack correctly, set it up for the trip and the Ibex becomes the more capable off-road option.

The extra weight is therefore not simply a penalty. It represents a wider tyre and a suspension system designed for riders who regularly leave smoother surfaces behind.

BOB Yak vs BOB Ibex: at-a-glance comparison

The choice is less about capacity and more about terrain, wheel compatibility, suspension and weight.

Choose the Yak when your route is mainly paved, compact gravel or relatively smooth trail and you want the lighter, simpler trailer.

Choose the Ibex when rough surfaces are central to the trip and suspension is worth the additional weight.

Both models use an open cargo frame, allowing equipment to be arranged according to the trip. A separate weather-resistant cargo bag or dry bag is recommended for camping equipment, clothing and anything that should not become part of the British weather.

Can a BOB trailer be used with an e-bike or mountain bike?

In many cases, yes—but the correct axle connection is essential.

The standard BOB attachment works with compatible quick-release or solid-axle arrangements. Many modern mountain bikes, gravel bikes and e-bikes use 12mm thru-axles instead.

A normal thru-axle cannot simply be replaced with a random longer bolt or adapted using improvised hardware.

The Robert Axle Project produces purpose-designed thru-axles for BOB trailers across a range of lengths, thread pitches and hub standards. Its BOB-specific products are used with road bikes, mountain bikes, fat bikes, carbon bikes and e-bikes, but the exact axle must match the individual bicycle.

Compatibility depends on more than the bike brand. We need to establish:

1. The complete bike model and model year

2. Rear hub spacing, such as 12 x 142mm or 12 x 148mm Boost

3. Overall axle length

4. Thread pitch, commonly 1.0, 1.5 or 1.75mm

5. Frame and dropout clearance

6. Whether the bicycle manufacturer approves trailer towing

7. The bicycle’s permitted trailer and system weight

This is where Hitch A Bike can help.

Send us the bike make, complete model, year and clear photographs of both sides of the rear axle. Include any axle markings or measurements available. We can then help identify whether the supplied BOB system is appropriate or whether a dedicated replacement axle is required.

An e-bike can be an excellent tow bike because motor assistance helps on hills and when moving away with a load. It does not reduce braking distances or make an overloaded trailer safe.

Ride within the limits of the bike, brakes, trailer, route and conditions. You should also check that the bicycle manufacturer permits trailer towing before fitting any trailer or replacement axle.

How to pack a BOB trailer

A 32kg capacity can tempt riders to pack for every possible situation. Resist it.

Place dense items low and near the centre of the cargo area. Balance the load from side to side and secure everything so it cannot move when cornering or braking.

Sleeping bags and clothing can fill the upper space, while tools, food, water and cooking equipment should sit lower. Keeping the weight low helps preserve the trailer’s natural stability.

Waterproofs, snacks and repairs should remain accessible. A weather-resistant bag does not replace proper load restraint.

Before a long journey, complete a loaded test ride close to home. Practise:

• Slow turns

• Hill starts

• Controlled descending

• Firm braking

• Dismounting with the trailer attached

• Passing through gates and barriers

Check the attachment pins, axle, trailer tyre pressure, wheel security, reflectors and safety flag before departure and regularly during the trip.

Remember that the trailer adds length to the bicycle. Allow more space when pulling away, turning across a road or stopping beside other riders.

UK bikepacking routes and planning resources

Britain has an extraordinary network of tracks, bridleways, forest roads and quiet lanes. It also has gates, steps, mud and surfaces that change dramatically after rain.

“Gravel” does not automatically mean suitable for a loaded trailer.

Use route guides as a starting point, then inspect recent reports, mapping, access notes and elevation. A route that is enjoyable on an unloaded mountain bike may be much more demanding when towing camping equipment.

Rebellion Way, Norfolk

Cycling UK’s Rebellion Way is a 232-mile circular route around Norfolk using quiet roads, byways, cycle paths and bridleways.

Its mostly flatter character makes it an approachable first multi-day adventure.

Especially useful for trailer riders, Cycling UK provides a trike and trailer alternative route, developed to identify barriers, challenges and possible diversions. The route page also links to the official Rebellion Way Facebook group for community updates and local knowledge.

King Alfred’s Way

The King Alfred’s Way is a roughly 350km circular route through historic Wessex.

It connects sections of the Ridgeway, South Downs Way, North Downs Way riders’ route and Thames Path, passing landscapes and historical locations including Winchester, Salisbury, Stonehenge and Avebury.

It is a superb target for gravel and mountain bikes, but weather can significantly alter its difficulty.

With a trailer, assess the route section by section rather than assuming every bridleway, rut or gate will be straightforward. Plan conservative daily distances and leave time for sections where pushing may be more sensible than riding.

Great North Trail

Cycling UK’s Great North Trail links the Peak District with Cape Wrath or John o’Groats across approximately 800 miles.

It travels through several National Parks and some of Britain’s most impressive upland landscapes.

This is an inspirational long-distance project rather than an obvious first trailer tour. Some sections may be excellent, while others include remote terrain, gates and more technical ground.

Its individual route chapters are valuable for planning shorter expeditions without committing to the entire journey.

National Cycle Network

The Sustrans National Cycle Network helps riders build lower-traffic journeys using traffic-free paths, signed routes and quieter roads.

It can be particularly useful for a first overnight trip or for connecting a railway station with a campsite.

Check current surface and access information before travelling. Some barriers intended to restrict motor vehicles can also be awkward with a long bicycle-and-trailer combination.

BIKEPACKING.com

BIKEPACKING.com’s route library provides routes, photographs, GPX information, terrain notes and logistical advice.

Its dedicated pages for England and Wales include everything from local overnighters to demanding mountain journeys.

Treat difficulty ratings as guidance, then make an additional judgement for a trailer.

A short hike-a-bike for an unloaded rider is very different with a bicycle, BOB trailer and several days of camping equipment.

Communities and media worth following

Local knowledge can transform route planning.

The Rough-Stuff Fellowship is a long-established UK off-road cycling club for riders interested in tracks, trails, touring and bikepacking. It is an excellent resource for people whose idea of a good road does not necessarily involve much tarmac.

The Racing Collective is a UK bikepacking community focused on self-supported riding and events. Even when racing is not your goal, its route culture and practical experience can provide inspiration for longer journeys.

Cycling UK’s local group finder can help locate cycling clubs and community rides near you.

Social groups are especially useful for recent conditions. Ask specific questions:

• Are the gates trailer-friendly?

• Has forestry work closed a section?

• Is the ground rideable after recent rain?

• Are there steps or compulsory carrying sections?

• Where is the last reliable food or water stop?

• Is there secure cycle-and-trailer storage at the campsite?

The useful answer is often hidden in details that a GPX line cannot show.

Which BOB cargo trailer is right for your adventure?

The BOB Yak and BOB Ibex share the same idea: carry equipment low, keep the trailer narrow and allow it to track behind the bike.

The BOB Yak 26 is the lighter, simpler choice for 26-inch bikes, touring, commuting and smoother mixed terrain.

The BOB Ibex 28 adds adjustable suspension, a wider trailer tyre and compatibility with the listed 28-inch, 29er and 700c formats. It is the stronger option when rough gravel, forest roads and mountain-bike terrain are central to the plan.

Whichever model you choose, the advantage is not that it encourages you to carry everything.

It lets you carry the right equipment in a stable, organised way, so the bike remains a bicycle rather than becoming a collection of bags with handlebars.

Before ordering, send Hitch A Bike your bicycle make, model, year and rear-axle photographs. We can help check the appropriate trailer version and identify the correct BOB-compatible axle adaptor where required.

Then pack carefully, choose a route that suits the whole setup and go somewhere worth waking up outdoors for.
