Bombtrack Munroe Cargo
The Munroe Cargo is the “compact” cargo bike in the Bombtrack range: an aluminium frame purpose-built for carrying loads, a 20" front wheel to increase cargo space, and a frame-mounted front rack with capacity up to 30 kg. It is a bike designed to replace the car for a wide range of urban trips, while keeping manageable dimensions and surprisingly intuitive handling.
Use & why it makes sense in the city
Less car, cleaner air: the Munroe Cargo is built to carry home the weekly groceries, boxes, crates of water or supplies for a party without starting the engine. Every trip made by bike instead of by car means less traffic, less noise and fewer emissions in the city.
Stable even when fully loaded: the rack is mounted to the frame, not to the fork. The load does not “steer” with the handlebar, so the bike remains neutral and predictable even with substantial weight on the front.
Agile handling despite everything: the smaller front wheel improves manoeuvrability; the generous Kenda tyres and Lune i24 rims make it robust on cobbles, tram tracks and urban potholes.
Low gears for easy starts: the 36 / 22 double chainring with 11–36 9-speed cassette lets you pull away smoothly at traffic lights and tackle climbs with a loaded rack without bogging down.
Powerful, controllable brakes: Shimano hydraulic disc brakes with 160 mm rotors keep both you and your load under control at all times, even in the wet.
What riders and the cycling press say
The Munroe Cargo is no longer a new model: it is one of the long-standing cargo bikes in the Bombtrack catalogue and has built a solid reputation among daily users over the years. Independent tests describe it as a very stiff and robust bike, designed to last and to carry significant loads without becoming nervous or unpredictable.
Some riders say they chose it as a definitive alternative to a standard urban bike or a gravel bike: it is not the “fast” bike for records, but the one you actually use to get to work, go to the market, head to the park with the dog or bring home two crates of beer. That is exactly where the Munroe Cargo performs at its best: the more you load it, the more you realise how much less car you need.
Size guide
The Bombtrack Munroe Cargo is offered in two sizes (M, L) with mixed wheel sizes: 27.5" at the rear and 20" at the front. The manufacturer’s height guidance is:
M: recommended height approx. 165–182 cm
L: recommended height approx. 180–195 cm
These are guidelines based on height only: torso proportions, leg length, mobility and riding style can all shift the choice between one size and the other. For a more precise fit, you can speak with the Bikejamming team (info@bikejamming.it) or with a professional bike fitter, so the bike can be tailored to your real-world use.
Advice & custom setups
Are you thinking about using the Munroe Cargo to replace the car in the city, for weekly shopping or for work? Bikejamming can help you understand whether it is the right model for your context such as gradients, type of loads, parking and commuting needs, and configure it with the most suitable accessories: bags, crates, lights, locks, possible tubeless conversion and much more. The goal is simple: to put a cargo bike outside your door that genuinely encourages you to use the car less.

Height-based size recommendations are only a starting point: no single guideline can be 100% accurate for every rider. For that reason, if you are unsure between two sizes or want to make the most of the Munroe Cargo’s car-light potential, we recommend speaking with Bikejamming or a professional bike fitter.
Frequently asked questions about the Bombtrack Munroe Cargo
Can the Bombtrack Munroe Cargo really replace the car in the city?
Yes, and that is exactly the kind of use it was designed for: groceries, errands, commuting, transporting boxes or bulky but urban-friendly loads. The 30 kg front rack and compact cargo structure make it far more practical than a standard urban bike when there is something real to carry.
How much can the Bombtrack Munroe Cargo carry?
The Bombtrack Cargo front rack has a stated capacity of up to 30 kg. The maximum declared total weight for rider plus luggage is 140 kg.
Is the Bombtrack Munroe Cargo difficult to ride?
No, and that is one of its strengths. The 20" front wheel and frame-mounted rack help keep the handling more neutral and intuitive than you might expect from a cargo bike.
Why is a frame-mounted front rack important?
Because the load does not turn with the handlebar. This helps keep the steering more predictable and stable, especially when the front rack is full or when you are stopping and starting frequently in urban traffic.
Is the Bombtrack Munroe Cargo suitable for climbs or loaded starts from a standstill?
Yes. The 2x9 drivetrain with 36 / 22 tooth chainrings and an 11–36 cassette is designed to provide low, manageable gearing that is useful for traffic-light starts and climbs with a loaded front rack.
Is the Bombtrack Munroe Cargo a longtail?
No. It is a compact cargo bike with a dedicated front rack and 20" front wheel, designed to remain more manageable and less bulky than many longer cargo bikes.
Is the Bombtrack Munroe Cargo suitable for groceries or work-related loads?
Yes. That is one of the most natural uses for this model: weekly groceries, crates, boxes, urban equipment or light but bulky work materials all fit perfectly within the logic of the bike.
Does the Bombtrack Munroe Cargo come with lights as standard?
No. The specifications list the lights as not included.
Can the Bombtrack Munroe Cargo also be used with a trailer or a child seat?
Yes. Both a bike trailer and a seat tube-mounted child seat are listed as approved.
